Safety PrecautionsAccessoriesChoosing a Site1. Indoor unit.• The indoor unit should be sited in a place where:1) the restrictions on installation specified in the indoor unit installation drawings are met,2) both air intake and exhaust have clear paths met,3) the unit is not in the path of direct sunlight,4) the unit is away from the source of heat or steam,5) there is no source of machine oil vapour (this may shorten indoor unit life),6) cool air is circulated throughout the room,7) the unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as they may shorten the remote controller range,8) the unit is at least 3.5 ft (1m) away from any television or radio set (unit may cause interference with the picture or sound).2. Wireless remote controller.1) Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals areproperly received by the indoor unit (within 23 ft (7m)).• Before choosing the installation site, obtain user approval.A Mounting plate E Remote controller holder K Operation manualL Installation manualD Wireless remote controllerB Mounting plate fixing screws3/16” × 1”L (M4 × 25mm)F Fixing screws for remote controllerholder 1/8” × 13/16”L (M3 × 20mm)C Air-purifying filter withphotocatalytic deodorizing function G Dry batteries AAA.

A torque wrench should be used.If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.• Do not touch the heat exchanger fins.Improper handling may result in injury.• Be very careful about product transportation.Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.WARNING• When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than the specified refrigerant (R410A), such as air.(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting in 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 abnormally high pressure which could lead to equipment damage or and personal injury.• During installation, attach the refrigerant piping securely before running the compressor.If the compressor is not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causingabnormally high pressure which could lead to equipment damage and personal injury.• Be sure to install a ground fault circuit interrupter breaker.Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, or fire personal injury.
