Installation Space
Install the outdoor unit where there is enough space
for ventilation. Otherwise the unit may not operate
properly. Fig. 2-7 shows the minimum space require-
ment around the outdoor units when 3 sides are open
and only 1 side is shuttered, with open space above
the unit. The mounting base should be concrete or a
similar material that allows for adequate drainage.
Make provisions for anchor bolts, platform height, and
other site-specific installation requirements.
CAUTION
NOTE
G
Do not do any wiring or tubing within 30 cm of the
front panel, because this space is needed as a ser-
vicing space for the compressor.
G
Ensure a base height of 100 mm or more to ensure
that drainage water does not accumulate and
freeze around the bottom of the unit.
G
If installing a drain pan, install the drain pan prior to
installing the outdoor unit.
* Make sure there is at least 150 mm between the
outdoor unit and the ground.
Also, the direction of the tubing and electrical wiring
should be from the front of the outdoor unit.
G
Leave space open above
the unit.
G Construct louvers or other
openings in the wall, if
necessary, to ensure ade-
quate ventilation.
