5 EnglishPoints of the operation explanation3. SELECTION OF INSTALLATION LOCATIONWhen unpacking and moving the indoor unit after unpacked, do not apply force to the piping (refrig-erant and drain) and resin parts.(1) Select the installation location that meets the following conditions and get approval of the cus-tomer.• Where the cool and warm air spreads evenly in the room.• Where there is no obstacles in the air passage.• Where drainage can be ensured.• Where the ceiling lower surface is not inclined.• Where there is sufficient strength to withstand the mass of the indoor unit (if the strength is insufficient,the indoor unit may vibrate and get in contact with the ceiling and generate unpleasant chattering noise).• Where a space sufficient for installation and service can be ensured. (Refer to Fig. 1 and Fig. 2)• Where the piping length between the indoor and the outdoor units is ensured within the allowable length.(Refer to the installation manual attached to the outdoor unit.)• Where there is no risk of flammable gas leak.NOTE• If there is extra space required for * part, servicing can be conducted more easily if 200mm or more is secured.CAUTION• Install the indoor and outdoor units, power supply wiring, remote controller wiring and transmission wiringat least 1 meter away from televisions or radios to prevent image interference or noise.(Depending on the radio waves, a distance of 1 meter may not be sufficient to eliminate the noise.)• Install the indoor unit as far as possible from fluorescent lamps.If a wireless remote controller kit is installed, the transmission distance may be shorter in a room where anelectronic lighting type (inverter or rapid start type) fluorescent lamp is installed.(2) Use hanging bolts for installation. Investigate if the installation place can withstand the mass of theindoor unit and, if necessary, hang the indoor unit with bolts after it is reinforced by beams etc. (Refer tothe installation pattern paper (5) for the mounting pitch.).(3) Ceiling heightThis indoor unit can be installed up to 4.3m (for 35-71 model, 3.5m) of the ceiling.In addition to the general usage, since the items in the operation manual with the WARNING andCAUTION marks are likely to result in human bodily injuries and property damages, it is neces-sary not only to explain these items to the customer but also to have the customer read them.It is also necessary to explain the items of “NOT MALFUNCTION OF THE AIR CONDITIONER” to thecustomer and have the customer read them carefully.Fig. 1[ Required installation space (mm) ]*30 or more *30 or moreFig. 2DischargeObstacles2500 or morefrom floor levelFor high installationFloor level300 or moreSuction
