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.
●
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.
●
Set up the airflow increase in case of the following conditions.
Ceiling heights are: 2.7 m (Type 22-56)
3.0 m (Type 60-90)
3.6 m (Type 106-160)
If the floor-to-ceiling is high, the wind speed distribution will become poor. For the setting
method, see
Section “7-3. Others”.
●
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.
