INSTALLATION

 

SITE

1

Select an installation site where the following conditions are
fulfilled and that meets your customer's approval.

-

The installation location is frost-free.

-

Where optimum air distribution can be ensured.

-

Where nothing blocks air passage.

-

Where condensate water can be properly drained.

-

Where the floor or wall is strong enough to bear the indoor 
unit weight.

-

Where sufficient clearance for maintenance and service can 
be ensured.

-

Where piping between indoor and outdoor units is possible 
within the allowable limit. (Refer to the installation manual of 
the outdoor unit.)

-

This is a class A product. In a domestic environment this 
product may cause radio interference in which case the user 
may be required to take adequate measures.

-

Keep indoor unit, outdoor unit, power supply wiring and 
transmission wiring at least 1 meter 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 1 meter is kept.)

-

When installing the wireless remote controller kit, the 
communication distance between wireless remote controller 
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.

-

Do not place objects that are susceptible to moisture directly 
beneath the indoor or outdoor units. Under certain 
conditions, condensation on the main unit or refrigerant 
pipes, air filter dirt or drain blockage may cause dripping, 
resulting in fouling or failure of the object concerned.
