2-2. Outdoor Unit
AVOID:
heat sources, exhaust fans, etc.
damp, humid or uneven locations
indoors (no-ventilation location)
DO:
choose a place as cool as possible.
choose a place that is well ventilated.
allow enough room around the unit for air intake/
exhaust and possible maintenance.
Installation Space
Install the outdoor unit where there is enough space for ven-
tilation. Otherwise the unit may not operate properly. Fig. 2-6
shows the minimum space requirement 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
Leave space open above the
unit.
Construct louvers or other
openings in the wall, if nec-
essary, to ensure adequate
ventilation.
NOTE
Do not do any wiring or tubing within 1 ft. of the front
panel, because this space is needed as a servicing
space for the compressor.
Ensure a base height of 4 in. or more to ensure that
drainage water does not accumulate and freeze
around the bottom of the unit.
If installing a drain pan, install the drain pan prior to
installing the outdoor unit.
* Make sure there is at least 6 in. 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.
