Select an installation site where the following conditions are
fulfilled and that meets your customer's approval.
- Where optimum air distribution can be ensured.
- Where nothing blocks air passage.
- Where condensate water can be properly drained.
- Where the false ceiling is not noticeably on an incline.
- Where sufficient clearance for maintenance and service can be
ensured.
- Where there is no risk of flammable gas leaking.
- The equipment is not intended for use in a potentially explosive
atmosphere.
- Where piping between indoor and outdoor units is possible
within the allowable limit.(Refer to the installation manual of the
outdoor unit.)
- Keep indoor unit, outdoor unit, inter unit wiring and remote
control wiring at least 3.3 feet away from televisions and
radios.This is to prevent image interference and noise in those
electrical appliances.(Noise may be generated depending on
the conditions under which the electric wave is generated,even
if 3.3ft is kept.)
- When installing the wireless remote control kit, the distance
between wireless remote control and indoor unit might be
shorter if there are fluorescent lights who are electrically started
in the room.The indoor unit must be installed as far as possible
away from fluorescent lights.
