2. SELECTING THE INSTALLATION SITE
2-1. Indoor Unit
AVOID:
●
areas where leakage of flammable gas may be expected.
●
places where large amounts of oil mist exist.
●
direct sunlight.
●
locations near heat sources which may affect the performance of the unit.
●
locations where external air may enter the room directly. This may cause “condensation” on
the air discharge ports, causing them to spray or drip water.
●
locations where the remote controller will be splashed with water or affected by dampness or
humidity.
●
installing the remote controller behind curtains or furniture.
●
locations where high-frequency emissions are generated.
DO:
●
select an appropriate position from which every corner of the room can be uniformly cooled.
●
select a location where the ceiling is strong enough to support the weight of the unit.
●
make sure to install protective guards on the suction and discharge side to prevent
somebody from touching the fan motor, fan blades or heat exchanger.
●
select a location where tubing and drain pipe have the shortest run to the outdoor unit.
●
allow room for operation and maintenance as well as unrestricted airflow around the unit.
●
the limitation of the tubing length between the indoor and the outdoor units should be
referred to the Installation Instructions of the outdoor unit.
●
allow room for mounting the remote controller about 1 m off the floor, in an area that is not in
direct sunlight or in the flow of cool air from the indoor unit.

It is necessary to make space for the cleaning as well as
the maintenance of the drain pan and the heat exchanger.
Do not put any obstacle not to cause obstructing
maintenance or cleaning works.
If the place where the ceiling material cannot be removed,
make an opening section below the bottom surface of the
indoor unit in order to take it out.
If it is impossible to provide an opening, make space more
than 300 mm between the indoor unit’s bottom surface
and the ceiling material.
