RECEIVING AND INSTALLATION
I. STEP I--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 fox" shipping damage while unit is still oi1 shipping
pallet. If unit appears to be damaged or is torn loose fi'om its
securing points, have it examined by transportation inspec
tars before removal. Fox,yard claim papers directly to trans
portation company. Manufacturer is not responsible for any
damage incurred in transit.
Check all items against stripping list. hmnediately notify yotxr
local representative if any item is missing.
To prevent loss or dan]age, 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 tire 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 1/a inch. This is necessary
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 tire 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 minimmn 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.
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 tire handholds provided in the unit
basepan. Refer to Table 1 for operating weights. U:se extreme
caution m prevent (tamaqe when movJI\_ the unit. Unit mu_st
rolnaJi1 ill all u[)r_q]lt posJHoi1 duriil_ _1]] nlovillg oDer_lHolls.
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.
