RECEIVING AND INSTALLATION

I. STEP 1 — CHECK EQUIPMENT
A. Identify Unit
The unit model number and serial number are stamped on
the unit identification plate. Check this information against
shipping papers.
B. Inspect Shipment
Inspect for shipping damage while unit is still on shipping
pallet. If unit appears to be damaged or is torn loose from its
securing points, have it examined by transportation inspec-
tors before removal. Forward claim papers directly to trans-
portation company. Manufacturer is not responsible for any
damage incurred in transit.
Check all items against shipping list. Immediately notify your
local representative if any item is missing.
To prevent loss or damage, leave all parts in original pack-
ages until installation.
II. STEP 2 — PROVIDE UNIT SUPPORT
A. Slab Mount
Place the unit on a rigid, level surface, suitable to support
the unit weight. The flat surface should extend approxi-
mately 2-in. beyond the unit casing on the 2 sides. The duct
connection side and condensate drain connection sides should
be flush with the edge of the flat surface. A concrete pad or a
suitable fiberglass mounting pad is recommended.
A 6-in. wide gravel apron should be used around the flat sur-
face to prevent airflow blockage by grass or shrubs. Do not
secure the unit to the flat surface except where required by
local codes.
The unit should be level to within
for the unit drain to function properly.

III. STEP 3 — PROVIDE CLEARANCES
The required minimum service clearances and clearances to
combustibles are shown in Fig. 2-4. Adequate ventilation and
condenser air must be provided.
The condenser fan pulls air through the condenser coil and
discharges it through the fan on the top cover. Be sure that
the fan discharge does not recirculate to the condenser coil.
Do not locate the unit in either a corner or under an over-
head obstruction. The minimum clearance under a partial over-
hang (such as a normal house overhang) is 48 in. above the
unit top. The maximum horizontal extension of a partial over-
hang must not exceed 48 inches.
CAUTION: Do not restrict condenser airflow. An air
restriction at either the outdoor-air inlet or the fan dis-
charge can be harmful to compressor life.
Do not place the unit where water, ice, or snow from an
overhang or roof will damage or flood the unit. The unit may
be installed on wood flooring or on Class A, B, or C roof cov-
ering materials.
IV. STEP 4 — PLACE UNIT
Unit can be moved with the handholds provided in the unit
basepan. Refer to Table 1 for operating weights. Use extreme
caution to prevent damage when moving the unit. Unit must
remain in an upright position during all moving operations.
The unit must be level for proper condensate drainage; the
ground-level pad must be level before setting the unit in place.
When a field-fabricated support is used, be sure that the sup-
port is level and that it properly supports the unit.
