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 air flow 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 Tables 1-5 and 1-6.
●
allow room for mounting the remote controller about
1m off the floor, in an area that is not in direct
sunlight or in the flow of cool air from the indoor unit.
2-2. Outdoor Unit
AVOID:
●
heat sources and exhaust fans, etc. (Fig. 2-4)
●
damp, humid or uneven locations.
DO:
●
choose a place as cool as possible.
●
choose a place that is well ventilated and outside air
temperature does not exceed maximum 45°C
constantly.
●
allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 2-5)
●
use lug bolts or equal to bolt down unit, reducing
vibration and noise.
●
If cooling operation is to be used when the outdoor
air temperature is –5°C or below, install a duct on the
outdoor unit.
