Installation Manual

Ceiling height
Install the unit where the the bottom panel is higher than 2.5 m
(8.2 ft) so the user cannot easily touch.
Use installation hooks when installing. Check that the
ceiling is strong enough to support the weight of the indoor
unit. If there is a risk, reinforce the ceiling before installing
the unit.
For the space required for installation, see the figure below.

DANGER
Do not install the unit in an area where flammable materials
are present. This could cause an explosion, which could
result in serious injury or death.
WARNING
If the base underneath the unit is not strong enough to
support the weight of the unit, the unit could fall and
cause serious injury.
Select an installation site where the following conditions
are fulfilled and that meets your customer's approval
- Optimum air distribution can be ensured.
- Nothing blocks air passage.
- Condensate water can be properly drained.
- The false ceiling is not on a noticeable incline.
- There is sufficient clearance for maintenance and service.
- There is no risk of flammable gas leaking.
- The atmosphere is not potentially explosive.
-
-
Piping between the indoor and outdoor units is possible within the
allowable limit. (Refer to the installation manual of the outdoor
unit.)
To prevent image interference and noise, keep the indoor unit,
outdoor unit, inter-unit wiring, and remote control wiring at least 1
m away from televisions and radios. (Noise may be generated
depending on the conditions under which the electric wave is
generated, even if a distance of 1 m is maintained.)
- When installing the wireless remote control kit, the distance
between the wireless remote control and the indoor unit might be
shorter if there are fluorescent lights that are electrically started in
the room. The indoor unit must be installed as far as possible
from fluorescent lights.
