They both contain important information regarding safety. Be sure to observe all precautions without fail. • Meaning of WARNING and CAUTION notices WARNING .... Failure to follow these instructions properly may result in personal injury or loss of life. CAUTION ..... Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances. • The safety marks shown in this manual have the following meanings: Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt. • After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual. WARNING • Ask your dealer or qualified personnel to carry out installation work. Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire. • Install the air conditioner in accordance with the instructions in this installation manual. Improper installation may result in water leakage, electric shocks or fire. • Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire. • Install the air conditioner on a foundation strong enough to withstand the weight of the unit. A foundation of insufficient strength may result in the equipment falling and causing injury. • Electrical work must be performed in accordance with relevant local and national regulations and with instructions in this installation manual. Be sure to use a dedicated power supply circuit only. Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire. • Use a cable of suitable length. Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire. • Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal connections or wires. Improper connections or securing of wires may result in abnormal heat build-up or fire. • When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires so that the control box lid can be securely fastened. Improper positioning of the control box lid may result in electric shocks, fire or over heating terminals. • If refrigerant gas leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire. • After completing installation, check for refrigerant gas leakage. Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker. • When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specified refrigerant (R410A). The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury. • During installation, attach the refrigerant piping securely before running the compressor. If the compressor is not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury. • During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury. • Be sure to earth the air conditioner. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks. • Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fire. CAUTION • Do not install the air conditioner at any place where there is a danger of flammable gas leakage. In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out. • While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation. Improper drain piping may result in indoor water leakage and property damage. • Tighten the flare nut according to the specified method such as with a torque wrench. If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage. 1 ■English 01_EN_3P248445-1.fm Page 2 Wednesday, September 2, 2009 11:29 AM Indoor unit English Accessories A – H , A Mounting plate 1 D Remote controller holder 1 G Operation manual 1 B Titanium apatite photocatalytic air-purifying filter 2 E Dry battery AAA.

Refrigerant Piping Work With a multi indoor unit , install as described in the installation manual supplied with the multi outdoor unit. 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. (Cut exactly at right angles.) Remove burrs. Flaring Set exactly at the position shown below. A Die A Flare tool for R410A Conventional flare tool Clutch-type Clutch-type (Rigid-type) Wing-nut type (Imperial-type) 0-0.5mm 1.5-2.0mm 1.0-1.5mm Check Flare’s inner surface must be flaw-free. The pipe end must be evenly flared in a perfect circle. Make sure that the flare nut is fitted. WARNING • Do not use mineral oil on flared part. • Prevent mineral oil from getting into the system as this would reduce the lifetime of the units. • Never use piping which has been used for previous installations. Only use parts which are delivered with the unit. • Do never install a drier to this R410A unit in order to guarantee its lifetime. • The drying material may dissolve and damage the system. • Incomplete flaring may cause refrigerant gas leakage. ■English 6 01_EN_3P248445-1.fm Page 7 Wednesday, September 2, 2009 11:29 AM Refrigerant Piping Work 2. Refrigerant piping CAUTION • Use the flare nut fixed to the main unit. (To prevent cracking of the flare nut by aged deterioration.) • To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.) • Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage. 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.
