CAUTION
4-2. Indoor 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.
select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
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. 4-6
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 drain-
age. Make provisions for anchor bolts, platform height, and
other site-specifi c installation requirements.
Leave space open above the
unit.
Construct louvers or other
openings in the wall, if neces-
sary, to ensure adequate venti-
lation.
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 drain-
age water does not accumulate and freeze around the
bottom of the unit.
If installing a drain pan, install the drain pan prior to install-
ing 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.
