Selecting 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.
