Unit Location —
This heat pump is designed only
for outdoor installations. Choosing the location of
the unit should be based on minimizing the length
of the supply and return ducts. Consideration
should also be given to availability of electric
power, service access, noise, and shade.
Suffi cient clearance for unobstructed airfl ow
through the outdoor coil must be maintained in
order to achieve rated performance
See Figure
4
for minimum clearances to obstructions.
Air Filters —
A suitable air fi lter must be installed
in the return air system. Air fi lter pressure drop
must not exceed 0.08 inches w.c. at 300 fpm.
Condensate Drain —
Condensate is removed
from the unit through the 3/4” female pipe fi tting
located on the front side of the unit.
See Figure
5.
Install a 2 inch condensate trap in the drain
line of the same size and prime with water. When
connecting rigid drain line, hold the female fi tting
with a wrench to prevent twisting.
Do not over
tighten!
Refer to local codes and restrictions for
proper condensate disposal requirements.
UNIT INSTALLATION
Ground Level —
When installing the unit at
ground level, provide a concrete mounting pad
separate from the building foundation. The
pad must be level to insure proper condensate
disposal and strong enough to support the unit’s
weight. Refer to
Figure 3.
Make sure the slab is
a minimum of 2” above the grade and in an area
that drains well.
See Figure 6
