The indoor unit should be sited in a place where:

• the restrictions on installation specified in the

indoor unit installation drawings are met,

• both air intake and exhaust have clear paths met,
• the unit is not in the path of direct sunlight,
• the unit is away from the source of heat or steam,
• there is no source of machine oil vapour (this

may shorten indoor unit life),

• cool (heat) air is circulated throughout the room,
• the unit is away from electronic ignition type flu-

orescent lamps (inverter or rapid start type) as
they may shorten the remote control range,

• the unit is at least 1 metre away from any televi-

sion or radio set (unit may cause interference
with the picture or sound).

The outdoor unit should be sited in a place where:

• the restrictions on installation specified in the outdoor unit installation diagram are met,
• drain water causes no trouble or problem in particular,
• both air intake and exhaust have clear paths of air (they should be free of

snow in snowy districts),

• the unit is in a clear path of air but not directly exposed to rain, strong

winds, or direct sunlight,

• there is no fear of inflammable gas leakage,
• the unit is no directly exposed to salt, sulfidized gases, or machine oil

vapour (they may shorten outdoor unit life),

• operation noise or hot air flow does not cause trouble to neighbours,
• the unit is at least 3 metres away from any television or radio antenna.

• Turn on all the fluorescent lamps in the room, if any, and find the site where remote

controller signals are properly received by the indoor unit (within 7 metres).
