SECTION III: UNIT INSTALLATION
LOCATION
Before starting the installation, select and check the suitability of the
location for both the indoor and outdoor unit. Observe all limitations and
clearance requirements.
The outdoor unit must have sufficient clearance for air entrance to the
condenser coil, for air discharge, and for service access. See Figure 1.
If the unit is to be installed on a hot sun exposed roof or a black-topped
ground area, the unit should be raised sufficiently above the roof or
ground to avoid taking the accumulated layer of hot air into the outdoor
unit.
Provide an adequate structural support.
GROUND INSTALLATION
The unit may be installed at ground level on a solid base that will not
shift or settle, causing strain on the refrigerant lines and possible leaks.
Maintain the clearances shown in Figure 1 and install the unit in a level
position.
Normal operating sound levels may be objectionable if the unit is placed
directly under windows of certain rooms (bedrooms, study, etc.).
Condensate will drain from beneath the coil of the outdoor unit during
the defrost cycle. Normally this condensate may be allowed to drain
directly on the ground.
Elevate the unit sufficiently to prevent any blockage of the air entrances
by snow in areas where there will be snow accumulation. Check the
local weather bureau for the expected snow accumulation in your area.
Isolate the unit from rain gutters to avoid any possible wash out of the
foundation.
UNIT PLACEMENT
1. Provide a base in the pre-determined location.
2. Remove the shipping carton and inspect for possible damage.
3. Compressor tie-down bolts should remain tightened.
4. Position the unit on the base provided.
LIQUID LINE FILTER-DRIER
The heat pumps have a solid core bi-flow filter/drier located on the liquid
line.

For multiple unit installations, units must be spaced a minimum of 18
inches apart (coil face to coil face).

NEC CLASS 2 WIRING
The outdoor unit should not be installed in an area where mud or ice
could cause personal injury. Remember that condensate will drip
from the unit coil during heat and defrost cycles and that this conden-
sate will freeze when the temperature of the outdoor air is below
32°F.
Heat pumps will defrost periodically resulting in water drainage. The
unit should not be located where water drainage may freeze and cre-
ate a hazardous condition - such as sidewalks and steps.
Replacements for the liquid line drier must be exactly the same as
marked on the original factory drier. See Source 1 for O.E.M.
replacement driers.
