English 54) Set the suspension bolt. (Use W3/8 or M8-M10 size sus-pension bolts.)• Adjust the distance from the unit to the ceiling slabbeforehand. (Refer to Fig. 8)NOTENOTENOTENOTE• All the above parts are field supplied.5. INDOOR UNIT INSTALLATIONInstalling optional accessories before installing the indoorunit is easier.As for the parts to be used for installation work, be sure to usethe provided accessories and specified parts designated by ourcompany.(1) Secure the hooks to the eyebolts. (Refer to Fig. 9)NOTENOTENOTENOTE• To ensure they are safely secured, use the included wash-ers, and secure them with a double nut to make sure.(2) Lift the indoor unit’s main body, insert the bolt (M8) forthe hook into the attachment part on the hook, whilesliding the main body from the front. (Refer to Fig. 10)(3) Fasten the bolts for the hooks (M8) securely in the fourlocations, left and right. (Refer to Fig. 10)(4) Replace the screws for the hooks which had beenremoved (M5) securely in 2 places left and right. This isnecessary to prevent any forward and back deviance inthe main body of the indoor unit. (Refer to Fig. 10)(5) When hanging the indoor unit main body, be sure touse a level or a plastic tube with water in it to make surethe drain piping is set either level or slightly tilted, inorder to ensure proper drainage. (Refer to Fig. 11)A.When the drain piping is tilted to the right, or to the rightand 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 andback.Place it level, or tilt it slightly to the left or the back.(Within 1°.)CAUTIONSetting the unit at an angle opposite to the drain pipingmight cause leaks.6. REFRIGERANT PIPING WORK• For the outdoor unit refrigerant piping, refer to the installationmanual attached to the outdoor unit.• Carry out insulation of both gas and liquid refrigerant pipingsecurely. If not insulated, it may cause water leakage. Forgas piping, use insulation material of which heat resistanttemperature is not less than 120°C.For use under high humidity, strengthen the insulation mate-rial for refrigerant piping. If not strengthened, the surface ofinsulation material may sweat.• Before installation work, make sure that the refrigerant isR410A. (Unless the refrigerant is R410A, the normal opera-tion cannot be expected.)CAUTIONThis air conditioner is a dedicated model for new refriger-ant R410A. Make sure to meet the requirements shownbelow and carry out installation work.• Use dedicated piping cutters and flaring tools for R410A.• When making a flare connection, coat the flared innersurface only with ether oil or ester oil.• Use only the flare nuts attached to the air conditioner. Ifother flare nuts are used, it may cause refrigerant leak-age.• To prevent contamination or moisture from getting intothe piping, take measures such as pinching or taping thepipings.Do not mix substance other than the specified refrigerantsuch as air into the refrigeration circuit.If the refrigerant leaks during the work, ventilate the room. !
