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.
The unit must be installed in as level a position as possible while main-
taining the clearances shown in Figure 1.
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.
ROOF INSTALLATION
When installing units on a roof, the structure must be capable of sup-
porting the total weight of the unit, including a pad, lintels, rails, etc.,
which should be used to minimize the transmission of sound or vibra-
tion into the conditioned space.
WALL MOUNT INSTALLATION
Care must be taken to mount the outdoor unit on a solid base that is
sloped to shed water, secure from settlement, and is isolated from the
structural foundation or walls to prevent sound and vibration transmis-
sion into the living space.
On occasion, site conditions may require direct wall mounted brackets
to be used to locate and support the outdoor unit. In these applications,
care must be taken to address unit base pan support, structural integ-
rity, safe access and serviceability, as well as the possible sound and
vibration transmission into the structure. These applications are best
served by a properly engineered solution.
UNIT PLACEMENT
1. Provide a base in the pre-determined location.
2. Remove the shipping carton and inspect for possible damage.
3. Ensure that compressor tie-down bolts 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.

WARNING
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 condensate
will freeze when the temperature of the outdoor air is below 32°F.
!
NOTICE
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.
CAUTION
Failure to use the same as the original factory drier or using a substi-
tute drier or a granular type may result in damage to the equipment.
NOTICE
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. replace-
ment driers.
