2. SELECTING THE INSTALLATION SITE
2-1. Indoor Unit
AVOID:
areas where leakage of fl ammable 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 “sweating” on the air discharge ports, causing
them to spray or drip.
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 air fl ow around the unit.
install the unit within the maximum elevation difference above ●
or below the outdoor unit and within a total tubing length (L)
from the outdoor unit as detailed in the installation manual
packed with the outdoor unit.
allow room for mounting the remote controller about 3 ft. off ●
the fl oor, in an area that is not in direct sunlight nor in the
fl ow of cool air from the indoor unit.
The elevation (Low Silhouette Ducted, Slim Low Static ●
Ducted) between the bottom unit and the fl oor surface should
be at least 8 feet.
If the elevation (Low Silhouette Ducted, Slim Low Static ●
Ducted) between them is less than 8 feet, install a fi lter
(optional/fi eld supply) or a protective device (fi eld supply) not
to touch the electrical parts or fan with hands.
The air intake and outtake openings should be provided with ●
the same location of a room.
