HEAT PUMP INSTALLATION
Locating the Heat pump
• Select a solid, level position, preferably on a
concrete slab, slightly above the grade level,
and parallel to the home. DO NOT PLACE
UNIT UNDER THE HOME.
• The hot condenser air must be discharged up
and away from the home, and if possible, in a
direction with the prevailing wind.
• Do not place the unit in a confi ned space.
• If practical, place the heat pump and its ducts
in an area where they will be shaded from
the afternoon sun, when the heat load is
greatest.
• If possible, select a site for the unit that is as
close as possible to the proposed return grille
location.
• The length of the supply and return ducts
should be kept to a minimum with no sharp
radius bends.
Unpacking the Unit
It is recommended that the unit be unpacked
at the installation site to minimize damage due
to handling.
CAUTION:
Do not tip the unit on its side. Oil
may enter the compressor cylinders
and cause starting trouble. If unit has
been set on its side, restore to upright
position and do not run for several
hours. Then run unit for a few seconds.
Do this three or four times with fi ve
minutes between runs.
1. Remove the bands from around the unit.
2. Unfold the top and bottom cap fl anges.
3. Carefully remove the top cap and tube.
Minimum Clearances
Minimum clearances MUST be maintained from
adjacent structures to provide room for proper
servicing and air circulation. See Figure 2. DO
NOT install unit in a confi ned or recessed area that
will allow discharge air from the unit to re-circulate
into the condenser air inlet, through the coil.
Service Access Clearance:
Blower access panel side .......................... 24”
Electrical compartment access panel side ... 12”
Clearance between overhang and
top of unit ...............................................72”
Clearance around condenser coil area to
wall or shrubs (excludes duct panel side) .. 12”
Clearances to Combustible Materials:
Combustible Base (Wood or Class A, B, or C
roof Covering material) ...............................0”
Supply and Return Air Ducts .......................0”
Duct Connection side ..................................0”
Duct Requirements
The supply duct system, including the number
and type of registers, will have much more
effect on the performance of an air conditioning
system then any other factor. The duct must be
suffi ciently large to conduct an adequate amount
of air to each register.

CONDENSATE DRAINAGE
A 3/4” condensate fi tting extends out of the side
of the unit (Figure 3). The drain trap, shipped in
the electrical compartment, must be installed to
prevent water from collecting inside the unit.
1. Thread the elbow provided with the unit into
the drain connection until hand tight.
2. Connect the condensate tubing onto the fi tting,
forming a trap near the drain connection.
3. Route the condensate tube from the trap to
a suitable drain. NOTE: For proper drainage,
make sure the trap is level to the ground and
tubing outlet is below trap level.
