    when handling parts or reaching into the unit.

    !

    CAUTION

    INTRODUCTION

    This heat pump is fully self--contained and designed for outdoor

    installation. (See Fig. 1) Standard units are shipped in a

    horizontal--discharge configuration for installation on a ground

    level slab. Standard units can be converted to downflow (vertical)

    discharge configurations for rooftop applications.

    RECEIVING AND INSTALLATION

    Step 1 — Check Equipment

    Identify Unit

    The unit model number and serial number are stamped on the unit

    identification plate. Check this information against shipping

    papers.

    Inspect Shipment

    Inspect for shipping damage before removing packaging material.

    If unit appears to be damaged or is torn loose from its anchorage,

    have it examined by transportation inspectors before removal.

    Forward claim papers directly to transportation company.

    Manufacturer is not responsible for any damage incurred in transit.

    Check all items against shipping list. Immediately notify the

    nearest equipment distributor if any item is missing. To prevent

    loss or damage, leave all parts in original packages until

    installation.

    If the unit is to be mounted on a curb in a downflow application,

    review Step 5 to determine which method is to be used to remove

    the downflow panels before rigging and lifting into place. The

    panel removal process may require the unit to be on the ground.

    Step 2 — Provide Unit Support

    Roof Curb

    Install accessory roof curb in accordance with instructions shipped

    with curb (See Fig. 4). Install insulation, cant strips, roofing, and

    flashing. Ductwork must be attached to curb.

    IMPORTANT: The gasketing of the unit to the roof curb is critical

    for a watertight seal. Install gasketing material supplied with the

    roof curb. Improperly applied gasketing also can result in air leaks

    and poor unit performance.

    Curb should be level to within 1/4 in. (6 mm) (See Fig. 7). This is

    necessary for unit drain to function properly. Refer to accessory

    roof curb installation instructions for additional information as

    required.

    Installation on older “G” series roof curbs.

    Two accessory kits are available to aid in installing a new “G”

    series unit on an old “G” roof curb.

    1. Accessory kit number CPADCURB001A00, (small chassis)

    and accessory kit number CPADCURB002A00, (large

    chassis) includes roof curb adapter and gaskets for the

    perimeter seal and duct openings. No additional

    modifications to the curb are required when using this kit.

    2. An alternative to the adapter curb is to modify the existing

    curb by removing the outer horizontal flange and use

    accessory kit number CPGSKTKIT001A00 which includes

    spacer blocks (for easy alignment to existing curb) and

    gaskets for the perimeter seal and duct openings. This kit is

    used when existing curb is modified by removing outer

    horizontal flange.

    UNIT/STRUCTURAL DAMAGE HAZARD

    Failure to follow this caution may result in property

    damage.

    Ensure there is sufficient clearance for saw blade when

    cutting the outer horizontal flange of the roof curb so there

    is no damage to the roof or flashing.

    !

    CAUTION

    Slab Mount

    Place the unit on a solid, level pad that is at least 2 in. (51 mm)

    above grade (See Fig. 8). The pad should extend approximately 2

    in. (51 mm) beyond the casing on all 4 sides of the unit. Do not

    secure the unit to the pad except when required by local codes.

    Step 3 — Provide Clearances

    The required minimum service clearances are shown in Fig. 2 and

    3. Adequate ventilation and outdoor air must be provided. The

    outdoor fan draws air through the outdoor coil and discharges it

    through the top fan grille. Be sure that the fan discharge does not

    recirculate to the outdoor coil. Do not locate the unit in either a

    corner or under an overhead obstruction. The minimum clearance

    under a partial overhang (such as a normal house overhang) is 48

    in. (1219 mm) above the unit top. The maximum horizontal

    extension of a partial overhang must not exceed 48 in. (1219 mm).

    IMPORTANT: Do not restrict outdoor airflow. An air restriction

    at either the outdoor--air inlet or the fan discharge may be

    detrimental to compressor life.

    Do not place the unit where water, ice, or snow from an overhang

    or roof will damage or flood the unit. Do not install the unit on

    carpeting or other combustible materials. Slab--mounted units

    should be at least 2 in. (51 mm) above the highest expected water

    and runoff levels. Do not use unit if it has been under water.

    Step 5 — Select and Install Ductwork

    The design and installation of the duct system must be in

    accordance with the standards of the NFPA for installation of

    non--residence type air conditioning and ventilating systems,

    NFPA 90A or residence--type, NFPA 90B and/or local codes and

    ordinances.

    Select and size ductwork, supply--air registers, and return air grilles

    according to ASHRAE (American Society of Heating,

    Refrigeration, and Air Conditioning Engineers) recommendations.

    The unit has duct flanges on the supply-- and return--air openings

    on the side of the unit.

    PERSONAL INJURY HAZARD

    Failure to follow this warning could result in personal

    injury or death.

    For vertical supply and return units, tools or parts could

    drop into ductwork Install a 90 degree turn in the return

    ductwork between the unit and the conditioned space. If a

    90 degree elbow cannot be installed, then a grille of

    sufficient strength and density should be installed to

    prevent objects from falling into the conditioned space.

    Units with electric heaters require 90 degree elbow in

    supply duct.

    !

    WARNING

    When designing and installing ductwork, consider the following:

    1. All units should have field--supplied filters or accessory

    filter rack installed in the return--air side of the unit.

    Recommended sizes for filters are shown in Table 1.

    2. Avoid abrupt duct size increases and reductions. Abrupt

    change in duct size adversely affects air performance.

    IMPORTANT: Use flexible connectors between ductwork and

    unit to prevent transmission of vibration. Use suitable gaskets to

    ensure weather tight and airtight seal. When electric heat is

    installed, use fireproof canvas (or similar heat resistant material)

    connector between ductwork and unit discharge connection. If

    flexible duct is used, insert a sheet metal sleeve inside duct. Heat

    resistant duct connector (or sheet metal sleeve) must extend 24--in.

    (610 mm) from electric heater element.

    3. Size ductwork for cooling air quantity (cfm). The minimum

    air quantity for proper electric heater operation is listed in

    Table 2. Heater limit switches may trip at air quantities

    below those recommended.

    4. Seal, insulate, and weatherproof all external ductwork. Seal,

    insulate and cover with a vapor barrier all ductwork passing

    through conditioned spaces. Follow latest Sheet Metal and

    Air Conditioning Contractors National Association

    (SMACNA) and Air Conditioning Contractors Association

    (ACCA) minimum installation standards for residential

    heating and air conditioning systems.

    5. Secure all ducts to building structure. Flash, weatherproof,

    and vibration--isolate duct openings in wall or roof

    according to good construction practices.

    Step 6 — Provide for Condensate Disposal

    NOTE: Ensure that condensate--water disposal methods comply

    with local codes, restrictions, and practices.

    The unit disposes of condensate through a 3/4 in. NPT female

    fitting that exits on the compressor end of the unit. Condensate

    water can be drained directly onto the roof in rooftop installations

    (where permitted) or onto a gravel apron in ground level

    installations. Install a field--supplied condensate trap at end of

    condensate connection to ensure proper drainage. Make sure that

    the outlet of the trap is at least 1 in. (25 mm) lower than the

    drain--pan condensate connection to prevent the pan from

    overflowing. Prime the trap with water. When using a gravel apron,

    make sure it slopes away from the unit.

    If the installation requires draining the condensate water away from

    the unit, install a field--supplied 2 --in. (51mm) trap at the

    condensate connection to ensure proper drainage. Condensate trap

    is available as an accessory or is field--supplied. Make sure that the

    outlet of the trap is at least 1 in. (25 mm) lower than the unit

    drain--pan condensate connection to prevent the pan from

    overflowing. Connect a drain tube using a minimum of

    field--supplied 3/4--in. PVC or field--supplied 3/4--in. copper pipe

    at outlet end of the 2--in. (51 mm) trap. (See Fig. 9) Do not

    undersize the tube. Pitch the drain tube downward at a slope of at

    least 1 in. (25 mm) every 10 ft (3 m) of horizontal run. Be sure to

    check the drain trough for leaks. Prime the trap at the beginning of

    the cooling season start--up.

    voltage of 208 vac.

    !

    WARNING

    Control Voltage Connections

    NOTE: Do not use any type of power--stealing thermostat. Unit

    control problems may result.

    Use no. 18 American Wire Gage (AWG) color--coded, insulated

    (35C minimum) wires to make the control voltage connections

    between the thermostat and the unit. If the thermostat is located

    more than 100 ft (30.5 m) from the unit (as measured along the

    control voltage wires), use no. 16 AWG color--coded, insulated

    (35 C minimum) wires.

    Standard Connections

    Locate the eight (nine on 3--phase) low voltage thermostat leads in

    24 volt splice box. See Fig. 10 for connection diagram. Run the

    low--voltage leads from the thermostat, through the control wiring

    inlet hole grommet (Fig. 2 and 3), and into the low--voltage splice

    box. Provide a drip loop before running wires through panel.

    Secure and strain relief all wires so that they do not interfere with

    operation of unit. A gray wire is standard on 3--phase units for

    connection to an economizer.

    If an accessory electric heater is installed, low voltage leads from

    heater must be connected to factory supplied control leads from

    Indoor Fan Board P4 connector.

    NOTE: If the unit 24V wires do not have a matching receptacle,

    cut the 24V wires from the electric heater plug, strip the ends, and

    wire nut together to match the schematic connections. If the electric

    heater 24V wires do not have a matching plug, cut the 24V wires

    from the unit receptacle, strip the ends, and wire nut together to

    match the schematic connections.

    Factory wires are provided for electric heat staging W1 and W2

    (W2 and W3 on IFB). If room thermostat has only one stage of

    supplemental heat, connect white and violet wires shown in Fig. 10

    to second stage heat field wire.

    Some electric heaters have four control wires (plus common wire).

    Consult unit wiring diagram and electric heater wiring diagram for

    additional details.

    Transformer Protection

    The transformer is of the energy--limiting type. It is set to withstand

    a 30--second overload or shorted secondary condition. If an

    overload or short is present, correct overload condition and check

    for blown fuse on Interface Fan Board. Replace fuse as required

    with correct size and rating.

    Accessory Electric Heaters Installation

    Electric heaters may be installed with the unit per instructions

    supplied with electric heater package. See unit rating plate for

    factory--approved electric heater kits.

    Sequence of Operation

    a. CONTINUOUS FAN

    (1.) Thermostat closes circuit R to G energizing the

    blower motor for continuous fan.

    b. COOLING MODE

    (1.) If indoor temperature is above temperature set

    point, thermostat closes circuits R to G, R to Y and

    R to O--The unit delivers cooling airflow.

    c. ELECTRIC HEATING MODE

    (1.) Thermostat closes circuit R to W/W1, or W2 and R

    to G. There are no on or off delays.

    d. HEAT PUMP HEATING MODE

    (1.) Thermostat closes circuits R to G and R to Y. The

    compressor, indoor and outdoor fans are energized.

    e. HEAT PUMP HEATING WITH AUXILIARY

    ELECTRIC HEAT

    (1.) Thermostat closes circuits R to G, R to Y and R to

    W/W1 or W2. The compressor, indoor and outdoor

    fans are energized, as well as the electric heat re-

    lays.

    f. DEFROST MODE

    The defrost mode is automatically energized by the de-

    frost board during heating mode. The defrost board en-

    ergizes “O” (reversing valve) and “W2” (electric heat). It

    also de--energizes the outdoor fan. When defrost is com-

    plete, unit will return to heating mode. If room thermo-

    stat is satisfied during defrost, unit will shut down and

    restart in defrost on next call for heat.

    sources are disconnected and tagged.

    4. Never attempt to repair soldered connection while

    refrigerant system is under pressure.

    5. Do not use torch to remove any component. System

    contains oil and refrigerant under pressure.

    To remove a component, wear protective goggles and

    proceed as follows:

    a. Shut off electrical power to unit and install lockout

    tag.

    b. Relieve and reclaim all refrigerant from system

    using both high-- and low--pressure ports.

    c. Cut component connecting tubing with tubing

    cutter and remove component from unit.

    d. Carefully unsweat remaining tubing stubs when

    necessary. Oil can ignite when exposed to torch

    flame.

    !

    WARNING

    Use the Start--Up Checklist supplied at the end of this book and

    proceed as follows to inspect and prepare the unit for initial

    start--up:

    1. Remove all access panels (see Fig. 21).

    2. Read and follow instructions on all DANGER, WARNING,

    CAUTION, and INFORMATION labels attached to, or

    shipped with, unit.

    3. Make the following inspections:

    a. Inspect for shipping and handling damages such as

    broken lines, loose parts, disconnected wires, etc.

    b. Inspect all field and factory--wiring connections. Be sure

    that connections are completed and tight. Ensure wires

    do not touch refrigerant tubing or sharp sheet metal

    edges.

    c. Inspect coil fins. If damaged during shipping and

    handling, carefully straighten fins with a fin comb.

    4. Verify the following conditions:

    a. Make sure that outdoor--fan blade is correctly positioned

    in fan orifice.

    b. Make sure that air filter(s) is in place.

    c. Make sure that condensate drain pan and trap are filled

    with water to ensure proper drainage.

    d. Make sure that all tools and miscellaneous loose parts

    have been removed.

    5. Each unit system has 2 Schrader--type ports, one low--side

    Schrader fitting located on the suction line, and one high--

    side Schrader fitting located on the compressor discharge

    line. Be sure that caps on the ports are tight.

    START--UP

    Checking Cooling and Heating Control Operation

    Start and check the unit for proper control operation as follows:

    (1.) Place room thermostat SYSTEM switch or MODE

    control in OFF position. Observe that blower

    motor starts when FAN mode is placed in FAN ON

    position and shuts down when FAN MODE switch

    is placed in AUTO position.

    (2.) Thermostat:

    When the room temperature rises to a point that is

    slightly above the cooling control setting of the

    thermostat, the thermostat completes the circuit

    between thermostat terminal R to terminals Y, O

    and G.These completed circuits through the

    thermostat connect contactor coil (C) (through unit

    wire Y) and Indoor Fan board (through unit wire

    G) across the 24--v. secondary of transformer

    (TRAN).

    (3.) Place system switch or MODE control in HEAT

    position. Set control above room temperature.

    Observe that compressor, outdoor fan, and indoor

    blower motors start. Observe that heating cycle

    shuts down when control setting is satisfied.

    (4.) When using an automatic changeover room

    thermostat place both SYSTEM or MODE control

    and FAN mode switches in AUTO positions.

    Observe that unit operates in Cooling mode when

    temperature control is set to “call for Cooling”

    (below room temperature), and unit operates in

    Heating mode when temperature control is set to

    “call for Heating” (above room temperature).

    NOTE: Once the compressor has started and then has stopped, it

    should not be started again until 5 minutes have elapsed. The

    defrost board has a built--in 5 minute delay between cycles. The 5

    minute compressor delay also applies to heat pump heating mode.

    Step 1 — Check for Refrigerant Leaks

    EXPLOSION HAZARD

    Failure to follow this warning could

    result in death, serious personal injury,

    and/or property damage.

    Never use air or gases containing

    oxygen for leak testing or operating

    refrigerant compressors. Pressurized

    mixtures of air or gases containing

    oxygen can lead to an explosion.

    !

    WARNING

    Proceed as follows to locate and repair a refrigerant leak and to

    charge the unit:

    1. Locate leak and make sure that refrigerant system pressure

    has been relieved and reclaimed from both high-- and low--

    pressure ports.

    2. Repair leak following Refrigerant Service procedures.

    NOTE: Install a bi--flow filter drier whenever the system has been

    opened for repair.

    3. Add a small charge of R--410A refrigerant vapor to system

    and leak--test unit.

    4. Recover refrigerant from refrigerant system and evacuate to

    500 microns if no additional leaks are not found.

    5. Charge unit with R--410A refrigerant, using an electronic

    scale. Refer to unit rating plate for required charge.

    PH4G -- -- B

  • Page 18:

    18

    Step 2 — Start--Up Adjustments

    Complete the required procedures given in the Pre--Start--Up

    section before starting the unit. Do not jumper any safety devices

    when operating the unit. Do not operate the unit in Cooling mode

    when the outdoor temperature is below 40_F(4_C) (unless

    accessory low--ambient kit is installed).

    IMPORTANT: Three--phase, scroll compressors are direction

    oriented. Unit must be checked to ensure proper compressor

    3--phase power lead orientation. If not corrected within 5 minutes,

    the internal protector will shut off the compressor. The 3--phase

    power leads to the unit must be reversed to correct rotation. When

    turning backwards, the difference between compressor suction and

    discharge pressures may be near zero.

    Checking and Adjusting Refrigerant Charge

    The refrigerant system is fully charged with R--410A refrigerant

    and is tested and factory sealed.

    EXPLOSION HAZARD

    Failure to follow this warning could

    result in death, serious personal injury,

    and/or property damage.

    Never use air or gases containing

    oxygen for leak testing or operating

    refrigerant compressors. Pressurized

    mixtures of air or gases containing

    oxygen can lead to an explosion.

    !

    WARNING

    NOTE: Adjustment of the refrigerant charge is not required

    unless the unit is suspected of not having the proper R--410A

    charge.

    NOTE: Some units have fixed orifice refrigerant metering

    devices. There is a different charging procedure for both expansion

    devices. Refer to the correct procedure for your unit.

    The charging label and the tables shown refer to system

    temperatures and pressures in cooling mode only. A refrigerant

    charging label is attached to the inside of the compressor access

    panel. (See Fig. 18 Subcool chart for units with TXV and

    superheat chart for units with fixed orifice.) The chart includes the

    required liquid line temperature at given discharge line pressures

    and outdoor ambient temperatures.

    A superheat chart is attached to the inside of the compressor access

    panel for the unit with fixed metering device. Refer to the charging

    procedure on the label.

    An accurate thermocouple-- or thermistor--type thermometer, and a

    gauge manifold are required when using the subcooling charging

    method for evaluating the unit charge. Do not use mercury or small

    dial--type thermometers because they are not adequate for this type

    of measurement.

    NOTE: Allow system to operate for a minimum of 15 minutes

    before checking or adjusting refrigerant charge.

    IMPORTANT: When evaluating the refrigerant charge, an

    indicated adjustment to the specified factory charge must always be

    very minimal. If a substantial adjustment is indicated, an abnormal

    condition exists somewhere in the cooling system, such as

    insufficient airflow across either coil or both coils.

    Proceed as follows:

    1. Remove caps from low-- and high--pressure service fittings.

    2. Using hoses with valve core depressors, attach low-- and

    high--pressure gauge hoses to low-- and high--pressure

    service fittings, respectively.

    3. Start unit and let run until system pressures stabilize.

    4. Measure and record the following:

    a. Outdoor ambient--air temperature (F[C] db).

    b. Liquid line temperature (F[C]) at TXV.

    c. Discharge (high--side) pressure (psig).

    d. Suction (low--side) pressure (psig) (for reference only).

    5. Using Cooling Charging Charts compare outdoor--air

    temperature (F[C] db) with the discharge line pressure

    (psig) to determine desired system operating liquid line

    temperature (See Fig. 18).

    6. Compare actual liquid line temperature with desired liquid

    line temperature. Using a tolerance of 2F(1.1C), add

    refrigerant if actual temperature is more than 2F(1.1C)

    higher than proper liquid line temperature, or remove

    refrigerant if actual temperature is more than 2F(1.1C)

    lower than required liquid line temperature.

    NOTE: If the problem causing the inaccurate readings is a

    refrigerant leak, refer to Check for Refrigerant Leaks section.

    Indoor Airflow and Airflow Adjustments

    UNIT OPERATION HAZARD

    Failure to follow this caution may result in unit damage.

    For cooling operation, the recommended airflow is 350 to

    450 cfm for each 12,000 Btuh of rated cooling capacity. For

    heating operation, the airflow must produce a temperature

    rise that falls within the range stamped on the unit rating

    plate.

    CAUTION

    !

    NOTE: Be sure that all supply--and return--air grilles are open,

    free from obstructions, and adjusted properly.

    ELECTRICAL SHOCK HAZARD

    Failure to follow this warning could result in personal

    injury or death.

    Disconnect electrical power to the unit and install lockout

    tag before changing blower speed.

    !

    WARNING

    This unit is factory-set up for use with a single cooling fan speed.

    In addition, this unit has the field-selectable capability to run two

    different cooling fan speeds: The rated cooling fan speed (350~400

    CFM/Ton) and an enhanced dehumidification fan speed (As low as

    320 CFM/Ton) for use with either a dehumidistat or a thermostat

    that supports dehumidification.

    The cooling speed is marked “LOW” on the interface fan board

    (IFB) (See Fig. 16) . The factory-shipped settings are noted in

    Table 5. There are 4 additional speed tap wires available for use in

    either electric heating or cooling (For color coding on the indoor

    fan motor leads, see Table 3). The additional 4 speed tap wires are

    shipped loose with vinyl caps and are located in the control box,

    near the interface fan board (IFB) (See Fig. 16).

    Single Cooling Fan Speed Set-up (Dehumidification

    feature not

    used)

    To change cooling speed:

    1. Remove the vinyl cap off of the desired speed tap wire

    (Refer to Table 3 for color coding). Add the wet coil

    pressure drop in Table 8 to the system static to determine the

    correct cooling airflow speed in Table 5 that will deliver the

    nominal cooling airflow as listed in Table 1 for each size.

    2. Remove the current speed tap wire from the “LOW”

    terminal on the interface fan board (IFB) (See Fig. 16) and

    place vinyl cap over the connector on the wire.

    3. Connect the desired speed tap wire to the “LOW” terminal

    on the interface fan board (IFB).

    19

    NOTE: If accessory electric heat is installed, and the electric heat

    fan speed is chosen to be the same as the normal cooling fan speed,

    the dry airflow must meet or exceed the minimum airflow speed

    specified in Table 2 for the specific size unit.

    Two Cooling Fan Speeds Set-up (Dehumidification

    feature

    used)

    IMPORTANT: Dehumidification control must open control

    circuit on humidity rise above set point.

    Use of the dehumidification cooling fan speed requires use of

    either a 24 VAC dehumidistat or a thermostat which includes

    control of a 24 VAC dehumidistat connection. In either case, the

    dehumidification control must open the control circuit on humidity

    rise above the dehumidification set point.

    1. Using Fig. 16, move the two pin DEHUM jumper from the

    “STD” position to the “DEHUM” position.

    2. Remove fan speed tap wire from the “LOW” terminal on

    the interface fan board (IFB) (See Fig. 16).

    3. Determine correct normal cooling fan speed for unit and

    application. Add the wet coil pressure drop in Table 8 to

    the system static to determine the correct cooling airflow

    speed in Table 5 that will deliver the nominal cooling

    airflow as listed in Table 1 for each size.

    NOTE: If accessory electric heat is installed, the dry

    airflow must meet or exceed the minimum airflow speed

    specified in Table 2 for the specific size unit. The electric

    heat fan speed will be the same as the normal cooling fan

    speed.

    4. Remove the vinyl cap off of the desired speed tap wire

    (Refer to Table 3 for color coding) for the normal cooling

    fan speed and place desired speed tap wire on “HIGH” on

    the interface board.

    5. Refer to airflow tables (Table 5) to determine allowable

    speeds for the dehumidification cooling fan speed. In Table

    5, speeds that are not allowed for dehumidification cooling

    are shaded.

    6. Remove the vinyl cap off of the desired speed tap wire

    (Refer to Table 3 for color coding) for the dehumidification

    cooling fan speed and place desired speed tap wire on the

    “LOW” connection on the interface board (IFB). Verify

    that static pressure is in the acceptable range for the speed

    tap to be used for dehumidification cooling.

    7. Use any spare vinyl plugs to cap any unused speed tap

    wires.

    Single Speed Cooling With Higher Electric Heat Speed

    This unit can also be configured to operate with single speed

    cooling and a higher speed for an accessory electric heater.

    1. Move the two pin DEHUM jumper located on control

    board (see Fig. 16) from the “STD” position to the “DE-

    HUM” position.

    2. See Table 2 for minimum airflow for electric heat operation.

    Add electric heater and filter pressure drop to duct system

    static pressure to determine total external static pressure.

    3. Select speed tap from Table 5 that will achieve required air-

    flow from Table 2.

    4. Remove the vinyl cap off of the desired speed tap wire (Re-

    fer to Table 3 for color coding).

    5. Connect the desired speed tap wire to the “HIGH” terminal

    on the interface fan board (IFB).

    UNIT OPERATION HAZARD

    Failure to follow this caution may result in unit component

    damage or improper operation.

    To use this mode, a speed connection must be made on the

    “HIGH” terminal that meets or exceeds the minimum

    airflow found in Table 2.

    !

    CAUTION

    ELECTRICAL SHOCK HAZARD

    Failure to follow this warning could result in personal

    injury or death.

    Disconnect electrical power to the unit and install lockout

    tag before changing blower speed.

    !

    WARNING

    Continuous Fan Operation

    When the DEHUM feature is not used, the continuous fan speed

    will be the same as cooling fan speed. When the DEHUM feature

    is used, the continuous fan will operate on IFB “LOW” speed

    when the DH control lead is not energized, or IFB “HIGH” speed

    when the DH lead is energized (see Fig. 16).

    Fig. 17 -- Typical Heat Pump Operation, Heating Mode

    Step 3 — Defrost Control

    Defrost Control

    The defrost control is used in all R--410A heat pump models. Its

    features include selectable defrost intervals of 30, 60, 90 minutes,

    and standard defrost speed up capability. This section describes the

    sequence of operation and trouble shooting methods for this

    control.

    Defrost

    Sequence

    The defrost control is a time/temperature control that has field

    selectable settings of 30, 60, and 90 minutes. These represent the

    amount of time that must pass after closure of the defrost

    thermostat before the defrost sequence begins.

    The defrost thermostat senses coil temperature throughout the

    heating cycle. When the coil temperature reaches the defrost

    thermostat setting, it will close, which energizes the DFT terminal

    and begins the defrost timing sequence. When the DTF has been

    energized for the selected time, the defrost cycle begins, and the

    control shifts the reversing valve into cooling position, and turns

    the outdoor fan off. This shifts hot gas flow into the outdoor coil

    which melts the frost from the coil. The defrost cycle is terminated

    when defrost thermostat opens, or automatically after 10 minutes.

    NOTE: TO EQUIPMENT OWNER: Consult your local dealer

    about the availability of a maintenance contract.

    PERSONAL INJURY AND UNIT DAMAGE HAZARD

    Failure to follow this warning could result in personal injury

    or death and unit component damage.

    The ability to properly perform maintenance on this

    equipment requires certain expertise, mechanical skills, tools

    and equipment. If you do not possess these, do not attempt to

    perform any maintenance on this equipment, other than those

    procedures recommended in the Owner’s Manual.

    !

    WARNING

    ELECTRICAL SHOCK HAZARD

    Failure to follow these warnings could result in personal

    injury or death:

    1. Turn off electrical power to the unit and install a lockout

    tag before performing any maintenance or service on this

    unit.

    2. Use extreme caution when removing panels and parts.

    3. Never place anything combustible either on or in contact

    with the unit.

    !

    WARNING

    UNIT OPERATION HAZARD

    Failure to follow this caution may result in improper

    operation.

    Errors made when reconnecting wires may cause improper

    and dangerous operation. Label all wires prior to

    disconnecting when servicing.

    CAUTION

    !

    The minimum maintenance requirements for this equipment are as

    follows:

    1. Inspect air filter(s) each month. Clean or replace when

    necessary.

    2. Inspect indoor coil, drain pan, and condensate drain each

    cooling season for cleanliness. Clean when necessary.

    3. Inspect blower motor and wheel for cleanliness each

    cooling season. Clean when necessary.

    4. Check electrical connections for tightness and controls for

    proper operation each cooling season. Service when

    necessary.

    Step 1 — Air Filter

    IMPORTANT: Never operate the unit without a suitable air filter

    in the return--air duct system. Always replace the filter with the

    same dimensional size and type as originally installed. See Table 1

    for recommended filter sizes.

    Inspect air filter(s) at least once each month and replace

    (throwaway--type) or clean (cleanable--type) at least twice during

    each cooling season and twice during the heating season, or

    whenever the filter becomes clogged with dust and lint.

    Indoor Blower and Motor

    NOTE: All motors are pre--lubricated. Do not attempt to lubricate

    these motors.

    NOTE: 460 volt units have a stepdown autotransformer that

    Step 2 — Outdoor Coil, Indoor Coil, and

    Condensate Drain Pan

    Inspect the condenser coil, evaporator coil, and condensate drain

    pan at least once each year.

    The coils are easily cleaned when dry; therefore, inspect and clean

    the coils either before or after each cooling season. Remove all

    obstructions, including weeds and shrubs, that interfere with the

    airflow through the condenser coil.

    Straighten bent fins with a fin comb. If coated with dirt or lint,

    clean the coils with a vacuum cleaner, using the soft brush

    attachment. Be careful not to bend the fins. If coated with oil or

    grease, clean the coils with a mild detergent--and--water solution.

    Rinse coils with clear water, using a garden hose. Be careful not to

    splash water on motors, insulation, wiring, or air filter(s). For best

    results, spray condenser coil fins from inside to outside the unit. On

    units with an outer and inner condenser coil, be sure to clean

    between the coils. Be sure to flush all dirt and debris from the unit

    base.

    Inspect the drain pan and condensate drain line when inspecting

    the coils. Clean the drain pan and condensate drain by removing all

    foreign matter from the pan. Flush the pan and drain trough with

    clear water. Do not splash water on the insulation, motor, wiring, or

    air filter(s). If the drain tube is restricted, clear it with a plumbers

    snake or similar probe device.

    Step 3 — Outdoor Fan

    Keep the condenser fan free from all obstructions to ensure proper

    cooling operation. Never place articles on top of the unit. Damage

    to unit may result.

    1. Remove 6 screws holding outdoor grille and motor to top

    cover.

    2. Turn motor/grille assembly upside down on top cover to

    expose fan blade.

    3. Inspect the fan blades for cracks or bends.

    4. If fan needs to be removed, loosen setscrew and slide fan off

    motor shaft.

    5. When replacing fan blade, position blade back to same posi-

    tion as before.

    6. Ensure that setscrew engages the flat area on the motor shaft

    when tightening.

    7. Replace grille.

    Step 4 — Electrical Controls and Wiring

    Inspect and check the electrical controls and wiring annually. Be

    sure to turn off the electrical power to the unit.

    Remove access panels (see Fig 22) to locate all the electrical

    controls and wiring. Check all electrical connections for tightness.

    Tighten all screw connections. If any discolored or burned

    connections are noticed, disassemble the connection, clean all the

    parts, restrip the wire end and reassemble the connection properly

    and securely.

    After inspecting the electrical controls and wiring, replace all the

    panels. Start the unit, and observe at least one complete cooling

    cycle to ensure proper operation. If discrepancies are observed in

    operating cycle, or if a suspected malfunction has occurred, check

    each electrical component with the proper electrical

    instrumentation. Refer to the unit wiring label when making these

    checkouts.

    Step 5 — Refrigerant Circuit

    Inspect all refrigerant tubing connections.

    If low performance is suspected, leak--test all refrigerant tubing

    using an electronic leak detector, or liquid--soap solution. If a

    refrigerant leak is detected, refer to Check for Refrigerant Leaks

    section.

    If no refrigerant leaks are found and low performance is suspected,

    refer to Checking and Adjusting Refrigerant Charge section.

    Step 6 — Indoor Airflow

    The heating and/or cooling airflow does not require checking

    unless improper performance is suspected. If a problem exists, be

    sure that all supply--air and return--air grilles are open and free

    from obstructions, and that the air filter is clean. When necessary,

    refer to Indoor Airflow and Airflow Adjustments section to check

    the system airflow.

    Step 7 — Metering Devices--TXV & Piston

    This unit uses 2 types of metering devices. The outdoor metering

    device is a fixed orifice and is contained in the brass hex--body in

    each liquid line feeding the outdoor coils. The indoor metering

    device is a TXV type device.

    Step 8 — Pressure Switches

    Pressure switches are protective devices wired into control circuit

    (low voltage). They shut off compressor if abnormally high or low

    pressures are present in the refrigeration circuit. These pressure

    switches are specifically designed to operate with R--410A

    systems. R--22 pressure switches must not be used as replacements

    for the R--410A system.

    Step 9 — Loss of Charge Switch

    This switch is located on the liquid line and protects against low

    suction pressures caused by such events as loss of charge, low

    airflow across indoor coil, dirty filters, etc. It opens on a pressure

    drop at about 20 psig. If system pressure is above this, switch

    should be closed. To check switch:

    1. Turn off all power to unit.

    2. Disconnect leads on switch.

    3. Apply ohm meter leads across switch. You should have

    continuity on a good switch.

    NOTE: Because these switches are attached to refrigeration

    system under pressure, it is not advisable to remove this device for

    troubleshooting unless you are reasonably certain that a problem

    exists. If switch must be removed, remove and recover all system

    charge so that pressure gauges read 0 psig. Never open system

    without breaking vacuum with dry nitrogen.

    Step 10 — High--Pressure Switch

    The high--pressure switch is located in the discharge line and

    protects against excessive condenser coil pressure. It opens at 650

    psig.

    High pressure may be caused by a dirty outdoor coil, failed fan

    motor, or outdoor air recirculation.

    To check switch:

    1. Turn off all power to unit.

    2. Disconnect leads on switch.

    3. Apply ohm meter leads across switch. You should have

    continuity on a good switch.

    Step 11 — Copeland Scroll Compressor (R--410A

    Refrigerant)

    The compressor used in this product is specifically designed to

    operate with R--410A refrigerant and cannot be interchanged.

    EXPLOSION HAZARD

    Failure to follow this warning could

    result in personal injury, death or

    property damage.

    Wear safety glasses and gloves when

    handling refrigerants. Keep torches

    and other ignition sources away from

    refrigerant and oils.

    !

    WARNING

    The scroll compressor pumps refrigerant throughout the system by

    the interaction of a stationary and an orbiting scroll. The scroll

    compressor has no dynamic suction or discharge valves, and it is

    more tolerant of stresses caused by debris, liquid slugging, and

    flooded starts. The compressor is equipped with an internal

    pressure relief port. The pressure relief port is a safety device,

    designed to protect against extreme high pressure. The relief port

    has an operating range between 550 and 625 psig differential

    pressure.

    Step 12 — Refrigerant System

    This step covers the refrigerant system including the compressor

    oil needed, servicing systems on roofs containing synthetic

    materials, the filter drier and refrigerant charging.

    refrigerant may be used in this system. Gauge set, hoses, and

    recovery system must be designed to handle R--410A. If you

    are unsure consult the equipment manufacturer.

    !

    WARNING

    PH4G -- -- B

  • Page 34:

    34

    This system uses R--410A refrigerant which has higher operating

    pressures than R--22 and other refrigerants. No other refrigerant

    may be used in this system. Gage set, hoses, and recovery system

    must be designed to handle R--410A. If you are unsure, consult the

    equipment manufacturer. Failure to use R--410A compatible

    servicing equipment or replacement components may result in

    property damage or injury.

    Compressor Oil

    The Copeland scroll compressor uses 3MAF POE oil. If additional

    oil is needed, use Uniqema RL32--3MAF. If this oil is not

    available, use Copeland Ultra 32 CC or Mobil Arctic EAL22 CC.

    This oil is extremely hygroscopic, meaning it absorbs water

    readily. POE oils can absorb 15 times as much water as other oils

    designed to HCFC and CFC refrigerants. Take all necessary

    precautions to avoid exposure of the oil to the atmosphere.

    Servicing Systems on Roofs with Synthetic Materials

    POE (polyolester) compressor lubricants are known to cause long

    term damage to some synthetic roofing materials. Exposure, even if

    immediately cleaned up, may cause embrittlement (leading to

    cracking) to occur in one year or more. When performing any

    service that may risk exposure of compressor oil to the roof, take

    appropriate precautions to protect roofing. Procedures which risk

    oil leakage include, but are not limited to, compressor replacement,

    repairing refrigerant leaks, replacing refrigerant components such

    as filter drier, pressure switch, metering device, coil, accumulator,

    or reversing valve.

    Synthetic Roof Precautionary Procedure

    1. Cover extended roof working area with an impermeable

    polyethylene (plastic) drip cloth or tarp. Cover an

    approximate 10x10 ft (3x3 m) area.

    2. Cover area in front of the unit service panel with a terry

    cloth shop towel to absorb lubricant spills and prevent

    run--offs, and protect drop cloth from tears caused by tools

    or components.

    3. Place terry cloth shop towel inside unit immediately under

    component(s) to be serviced and prevent lubricant run--offs

    through the louvered openings in the unit base.

    4. Perform required service.

    5. Remove and dispose of any oil contaminated material per

    local codes.

    Liquid Line Filter Drier

    The biflow filter drier is specifically designed to operate with

    R--410A. Use only factory--authorized components. Filter drier

    must be replaced whenever the refrigerant system is opened. When

    removing a filter drier, use a tubing cutter to cut the drier from the

    system. Do not unsweat a filter drier from the system. Heat from

    unsweating will release moisture and contaminants from drier into

    system.

    R--410A Refrigerant Charging

    Refer to unit information plate and charging chart. Some R--410A

    refrigerant cylinders contain a dip tube to allow liquid refrigerant to

    flow from cylinder in upright position. For cylinders equipped

    with a dip tube, charge R--410A units with cylinder in upright

    position and a commercial metering device in manifold hose.

    Charge refrigerant into suction--line.

    Step 13 — System Information

    Loss of Charge Switch

    The loss of charge switch is a protective device wired into control

    circuit (low voltage). It shuts off the compressor if abnormally low

    pressures are present in the refrigeration circuit.

    NOTE: Because these switches are attached to refrigeration

    system under pressure, it is not advisable to remove this device for

    troubleshooting unless you are reasonably certain that a problem

    exists. If switch must be removed, remove and recover all system

    charge so that pressure gauges read 0 psig. Never open system

    without breaking vacuum with dry nitrogen.

    Check Defrost Thermostat

    The defrost thermostat is usually located on the lowest liquid

    leaving circuit of the left condenser coil (see Fig. 23). The

    thermostat closes at 32_F(0_C) and opens at 65_F(18_C).

    The defrost thermostat signals heat pump that conditions are right

    for defrost or that conditions have changed to terminate defrost. It

    is a thermally actuated switch clamped to outdoor coil to sense its

    temperature. Normal temperature range is closed at 32_  3_F(0

     1.7_C) and open at 65_  5_F(18 2.8_C).

    NOTE: The defrost thermostat must be located on the liquid side

    of the outdoor coil on the bottom circuit and as close to the coil as

    possible. The factory location is on the left/back coil.
