•
This manual classifies the precautions into WARNINGS and CAUTIONS. Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNINGS
CAUTIONS
WARNINGS
CAUTIONS
Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.
Failure to follow any of CAUTION may in some cases result in grave consequences.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction.
Be sure to establish a proper
earth grounding connection.
Never attempt.
•
After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit according to the Operation Manual.
•
Installation should be left to the authorized dealer or another trained professional. Improper installation may cause water leakage, electrical shock, fire, or equipment damage.
•
Install the air conditioner according to the instructions given in this manual. Incomplete installation may cause water leakage, electrical shock, fire or equipment damage.
•
Be sure to use the supplied or exact specified installation parts. Use of other parts may cause the unit to come to lose, water leakage, electrical shock, fire or equipment damage.
• Install the air conditioner on a solid base that is level and can support the unit's weight.
An inadequate base or incomplete installation may cause injury or equipment damage in the event the unit falls off the base or comes loose.
•
Electrical work should be carried out in accordance with the installation manual and the national, state and local electrical wiring codes.
Insufficient capacity or incomplete electrical work may cause electrical shock, fire or equipment damage.
•
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. Follow all appropriate electrical codes.
•
Use the specified types of wires for electrical connections between the indoor and outdoor units. Follow all state and local electrical codes.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating, fire or euipment damage.
• After all installation is complete, check to make sure that no refrigerant is leaking.
(The refrigerant produces a toxic gas if exposed to flames.)
• Do not install the air conditioner where gas leakage would be exposed to open flames.
If the gas leaks and builds up around the unit, it may catch fire.
• Establish drain piping according to the instructions of this manual. Inadequate piping may cause water damage.
•
Tighten the flare nut according to the specified torque. A torque wrench should be used. If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.
• Do not touch the heat exchanger fins.
Improper handling may result in injury.
•
Be very careful about product transportation. Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.
•
Note for installing the outdoor unit. (For heat pump model only.) In regions of the country where the outside temperature is at or
below the freezing point, the drain may freeze. If so, it is recommended that an electric heater be installed in order to protect the drain from freezing.
•
After connecting all wiring be sure to shape the cables so that they do not put undue stress on the electrical covers, panels or terminals.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock,fire or equipment damage.
•
When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than the specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting in injury.)
• If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
• Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone ground.
Incomplete or inadequate grounding may cause equipment damage, or electrical shock and personal injury. A high surge current from lightning or other sources may cause damage to the air conditioner.
• Install an leak circuit breaker, as required. If an leak circuit breaker is not installed, electric shock may result.
•
Be sure to install a ground fault circuit interrupter breaker. Failure to install a ground fault circuit interrupter breaker may result in electrically shocks or personal injury.
•
During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the shut-off valve is open during
pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormally high pressure which could lead to equipment damage or and personal injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the compressor is not attached and the shut-off valve is open during pump-down, air will be sucked in when the compressor is run, causing
abnormally high pressure whichcould lead to equipment damage and personal injury.
•
For wiring, use a wire or cable long enough to cover the entire distance with no splices if possible. Do not use an extension cord. Do not put other
loads on the power supply.Use a only a separate dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock,fire or equipment damage.)

1. Flaring the pipe end
1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing downward
so that the chips do not enter the pipe.
3) Put the flare nut on the pipe.
4) Flare the pipe.
5) Check that the flaring is properly made.
2-2. Selection of Copper and Heat Insulation materials
• When using commercial copper pipes and fittings, observe the following:
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052 kW/mK (0.024-0.030 Btu/fth˚F)
Refrigerant gas pipe’s surface temperature reaches 230˚F max.
Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
3) Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
2. Refrigerant piping
1) Align the centres of both flares and tighten the flare nuts 3 or 4 turns
by hand. Then tighten them fully with the torque wrenches.
• Use torque wrenches when tightening the flare nuts to prevent
damage to the flare nuts and escaping gas.
2) To prevent gas leakage, apply refrigeration machine oil on both
inner and outer surfaces of the flare.
1) Do not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would reduce the unit life.
3)
Never use piping which has been used for previous installations. Only use parts which are provided with the unit.
4) Do never install a refrigerant drier to this unit.
5) The drying material may dissolve and damage the system.
6) Incomplete or improper flaring may cause refrigerant gas leakage.
Warning
2-1. Cautions on Pipe Handling
1) Protect the open end of the pipe against dust and moisture.
2) All pipe bends should be as gentle as possible. Use a pipe
bender for bending.
(Bending radius should be 1 3/16 to 1 9/16in or larger.)
