9 English(5) When hanging the indoor unit, make sure to use the level to have better drainage and install it hor-izontally. Also, if it is possible at the installation site, install so that the drain piping side is slightlylower. (Refer to Fig. 12)CAUTION• Setting the indoor unit at an angle opposite to the drain piping might cause a water leakage.• Do not insert materials other than that specified into the clearance between the hanger and thewasher for hanger (3).Unless the washers are properly attached, the hanging bolts may come off from the hanger.A.When the drain piping is tilted to the right, or to the right and back.Place it level, or tilt it slightly to the right or the back. (Within 1°)B.When the drain piping is tilted to the left, or to the left and back.Place it level, or tilt it slightly to the left or the back. (Within 1°)WARNINGThe indoor unit must be securely installed on a place that can withstand the mass.If the strength is insufficient, the indoor unit may fall down and cause injuries.6. REFRIGERANT PIPING WORK• For the outdoor unit refrigerant piping, refer to the installation manual attached to the outdoor unit.• Carry out insulation of both gas and liquid refrigerant piping securely. If not insulated, it may cause waterleakage. For gas piping, use insulation material of which heat resistant temperature is not less than 120°C.For use under high humidity, strengthen the insulation material for refrigerant piping. If not strengthened,the surface of insulation material may sweat.• Before installation work, make sure that the refrigerant is R410A. (Unless the refrigerant is R410A, the nor-mal operation cannot be expected.)CAUTIONThis air conditioner is a dedicated model for new refrigerant R410A. Make sure to meet the require-ments shown below and carry out installation work.• Use dedicated piping cutters and flaring tools for R410A.• When making a flare connection, coat the flared inner surface only with ether oil or ester oil.• Use only the flare nuts attached to the air conditioner. If other flare nuts are used, it may causerefrigerant leakage.• To prevent contamination or moisture from getting into the piping, take measures such as pinch-ing or taping the pipings.Do not mix substance other than the specified refrigerant such as air into the refrigeration circuit.If the refrigerant leaks during the work, ventilate the room.• Remove the stay for packing and delivering (reinforcing plate) before refrigerant piping work.(Refer to Fig. 18)• The refrigerant is pre-charged in the outdoor unit.A A.BB≤ 1˚≤ 1˚≤ 1˚Fig. 12
