Note: In case of adding refrigerant, comply with the quantity specified for the refrigerating cycle. CAUTION • Do not discharge the refrigerant into the atmosphere. Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit. • For additional charging, charge the refrigerant from liquid phase of the gas cylinder. If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly. To maintain the high pressure of the gas cylinder, warm the gas cylinder with warm water (under 40°C) during cold season. But never use naked fire or steam.

Remove the service port cap of the stop valve on the side of the outdoor unit gas pipe. (The stop valve will not work in it initial state fresh out of the factory (totally closed with cap on).) Connect the gauge manifold valve and the vacuum pump to the service port of the stop valve on the gas pipe side of the outdoor unit. Run the vacuum pump. (Vacuumize for more than 15 minutes.) Check the vacuum with the gauge manifold valve, then close the gauge manifold valve, and stop the vacuum pump. Leave as it is for one or two minutes. Make sure the pointer gauge manifold valve remains in the same position. Confirm that the pressure gauge shows–0.101 Mpa [Gauge] (–760 mmHg). Pipe length up to 7 m No gas charge is needed. Pipe length exceeding 7 m Charge the prescribed amount of gas. (refer to 3) Remove the gauge manifold valve quickly from the service port of the stop valve. After refrigerant pipes are connected and evacuated, fully open all stop valves on both sides of gas pipe and liquid pipe. Operating without fully opening lowers the performance and this causes trouble. Tighten the cap to the service port to obtain the initial status. Retighten the cap. Leak test 3.

THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY • Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY” before installing the air conditioner. • Be sure to observe the cautions specified here as they include important items related to safety. • The indications and meanings are as follows. WARNING Could lead to death, serious injury, etc. CAUTION Could lead to serious injury in particular environments when operated incorrectly. • After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS in a handy place on the customer’s site. WARNING ■ Do not install the unit by yourself (customer). Incomplete installation could cause injury due to fire, electric shock, the unit falling or leakage of water. Consult the dealer from whom you purchased the unit or special installer. ■ Install the unit securely in a place which can bear the weight of the unit. When installed in an insufficient strong place, the unit could fall causing injury. ■ Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Incomplete connecting and fixing could cause fire. ■ Do not use intermediate connection of the power cord or the extension cord and do not connect many devices to one AC outlet. It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc. ■ Check that the refrigerant gas do not leak after installation has com- pleted. If refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated. ■ Perform the installation securely referring to the installation manual. Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or leakage of water. ■ Perform electrical work according to the installation manual and be sure to use an exclusive circuit. If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock. ■ Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely. If the electrical cover in the indoor unit and/or the service panel in the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc. ■ Be sure to use the part provided or specified parts for the installation work. The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc. ■ Be sure to cut off the main power in case of setting up the indoor electronic control P.C. board or wiring works. It could cause an electric shock. ■ The appliance shall be installed in accordance with national wiring regulations. ■ When installing or relocating the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.

INDOOR/OUTDOOR UNIT CONNECTION FINISHING AND TEST RUN INSTALLATION INFORMATION FOR THE AIR CONDI- TIONER WITH R410A REFRIGERANT • This room air conditioner adopts an HFC refrigerant (R410A) which will never destroy the ozone layer. • Pay particular attention to the following points, though the basic installation procedure is same as that for R22 air conditioners. 1 As R410A has a working pressure approx. 1.6 times as high as that of R22, some special tools and piping parts / materials are required. (Refer to the table below.) 2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and installation, since it is more susceptible to contaminations than R22. 3 For refrigerant piping, use clean, pressure-proof parts / materials specifically designed for R410A. (Refer to 2. Refrigerant piping.) 4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change. 6-1 Tools dedicated for the air conditioner with R410A refrigerant The following tools are required for R410A refrigerant. Some R22 tools can be substituted for R410A tools. The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being charged into the unit. (Cap size has been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads.) R410A tools Can R22 tools be used? Description R410A has high pressures beyond the meas- urement range of existing gauges. Gauge manifold No Port diameters have been changed to prevent any other refrigerant from being charged into the unit. Charge hose No Hose material and cap size have been changed to improve the pressure resistance. Gas leak detector No Dedicated for HFC refrigerant. Torque wrench Yes 1/4 and 3/8 No 1/2 and 5/8 Flare tool Yes Clamp bar hole has been enlarged to reinforce the spring strength in the tool. Flare gauge New Provided for flaring work (to be used with R22 flare tool). New Provided to prevent the back flow of oil. This adapter enables you to use existing vacuum pumps. New It is difficult to measure R410A with a charging cylinder because the refrigerant bubbles due to high pressure and high-speed vaporization. No: Not substitutable for R410A Yes: Substitutable for R410A 6-2 FLARING WORK • Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure. 1 Pipe cutting • Cut the copper pipe correctly with pipe cutter. 2 Burrs removal • Completely remove all burrs from the cut cross section of pipe. • Put the end of the copper pipe to downward direction as you remove burrs in order to avoid to let burrs drop in the piping. Copper pipe Good No good Tilted Uneven Burred Burr Copper pipe Spare reamer Pipe cutter Flare nut Copper pipe Die Copper pipe Flare nut Die Copper pipe Yor k Smooth all around Even length all around Inside is shining without any scratches. 90° Flaring tool Wing nut type Clutch type Be careful the drain hose is not raised. Separate the 2 connecting pipes and apply insulation individually. 8 mm thickness thermal insulation plastic Decide the installation position using mark on the installation plate indicating the indoor unit size as reference. When the piping is to be attached to a wall containing metals (tin plated) or metal netting, use a chemically treated wooden piece 20 mm or thicker between the wall and the piping or wrap 7 to 8 turns of insulation vinyl tape around the piping. Lock the catch. Front Piping can be directed towards rear, right, downward, left or left-rear directions. Rear side Right Rear Downward Left-rear Left Units should be installed by licensed contractor according to local code requirement. PIPING PREPARATION 1 Specifications Use the refrigerant pipes that meet the following specifications. Pipe Outside diameter Insulation thickness Insulation material mm mm For liquid A18/A24 6.35 8 A26/A30 9.52 8 For gas A18 12.7 8 A24/A26/A30 15.88 8 • Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm (for ø6.35, 9.52) or 1.0 mm (for ø12.7, ø15.88). Never use any pipe with a thickness less than 0.8 mm (for ø6.35, 9.52) or 1.0 mm (for ø12.7, ø15.88), as the pressure resistance is insufficient. 2 Ensure that the 2 refrigerant pipes are insulated to prevent condensation. 3 Refrigerant pipe bending radius must be 100 mm or more. CAUTION Be sure to use the insulation of specified thickness. Excessive thickness may cause incorrect installation of the indoor unit and lack of thickness may cause dew drippage. 4.

If you want to know how to release this function, consult the service center. • When the indoor unit is controlled with the remote controller, the operation mode, the set temperature, and the fan speed are memorized by the indoor electronic control P.C. board. The auto restart function sets to work the moment the power has restored after power failure, then, the unit will restart automatically. If the unit is operated in “I FEEL CONTROL” mode before power failure, the operation is not memorized. In “I FEEL CONTROL” mode, the operation is decided by the initial room temperature at (re)start. Operation 1 If the main power (230V AC) has been cut, the operation settings remain. 2 When three minutes have passed after power was restored, the unit will restart automatically according to the memory. Notes: • The operation settings are memorized when 10 seconds have passed after the remote controller was operated. • If the main power is turned off or a power failure occurs while AUTO START/STOP timer is active, the timer setting is cancelled. As these models are equipped with the auto restart function, the air conditioner should start operating at the same time that a power has restored. • If the unit has been off with the remote controller before power failure, the auto restart function does not work as the power button of the remote controller is off. • To prevent breaker off due to the rush of starting current, systematize other home appliances not to turn on at the same time. 4-6 PIPE FORMING • Place the drain hose below the refrigerant piping. • Make sure that the drain hose is not heaved or snaked. • Do not pull the hose to apply the tape. • When the drain hose passes the room, be sure to wrap insulation material (obtain- able at a store) around it. • Wrap the felt tape 7 around the pipe and the drain hose, then put the pipe in the back space of the indoor unit. Drain hose Be careful drain hose is not heaved. Firmly apply piping tape G from the end. Cut off in case of right piping. Cut off in case of downward piping. Drain cap FOR REAR, RIGHT OR DOWNWARD PIPING • Pipe arrangement Put the refrigerant piping and the drain hose together, then apply piping tape G to them. • Insert the piping and the drain hose into the wall hole sleeve C, and hook the upper part of the indoor unit on the installation plate 1. • Check if the indoor unit is hooked securely on the installation plate 1 by moving the unit to left and right. • Thrust the lower part of the indoor unit into the installation plate 1.
