INSTALLATION
Step 1 -- Unpack and Inspect Units
-- Units are
packaged for shipment to avoid damage during nonnal transit
and handling. It is the receiving party's responsibility to inspect
the equipment upon arrival. Any obvious damage to the carton
and/or its contents should be reported on the bill of lading and a
claim should be filed with the transportation company and the
factory. Unit should always be stored in a dry place, and in the
proper orientation as marked on the carton.
To avoid equipment damage, do not lift unit by the drain
pipe or refrigerant piping. Unit should be lifted using the
mounting brackets.
After determining the condition of the carton exterior, care-
fully remove each unit from the carton and inspect for hidden
damage. Check to make sure that items such as thermostats,
controller etc. are accounted for whether packaged separately
or shipped at a later date. Any hidden damage should be re-
corded, a claim should be filed with the transportation compa-
ny, and the factory should be notified. In the event a claim for
shipping damage is filed, the unit, shipping carton, and all
packing must be retained for physical inspection by the trans-
portation company. All units should be stored in the factory
shipping carton with internal packaging in place until installa-
tion.
PROTECTING UNITS FROM DAMAGE -- Do not apply
force or pressure to the coil, piping, or drain stub-outs during
handling. All units should be handled by the chassis or as close
as possible to the unit mounting point locations.
The unit must always be properly supported. Temporary
supports used during installation or service must be adequate to
hold the unit securely. To maintain warranty, protect units
against hostile enviromnents (such as rain, snow or extreme
temperature), theft, vandalism, and debris on jobsite. Equip-
ment covered in this manual is not suitable for outdoor installa-
tions. Do not allow foreign material to fall into drain pan. Pre-
vent dust and debris from being deposited on motor, fan wheels
and coils. Failure to do so may have serious adverse effects on
unit operation and in the case of motor and blower assembly,
may result in ilrunediate or premature failure. Failure of any
unit caused by deposits of foreign material on the motor or
blower wheels will not be covered by the manufacturer's war-
ranty. Some units and/or job conditions may require some form
of temporary covering during construction.
PREPARING JOBSITE FOR UNIT INSTALLATION --
To save time and to reduce the possibility of costly errors, set
up a complete sample installation in a typical room at jobsite.
Check all critical dfinensions such as pipe, wire, and duct con-
nections requirements. Refer to job drawings and product
dimension drawings as required. Instruct all trades in their
parts of the installation. Units must be installed in compliance
with all applicable local code requirements.
IDENTIFYING AND PREPARING UNITS -- Be sure
power requirements match available power source. Refer to
unit nameplate and wiring diagram. In addition:
• Check all tags on unit to determine if shipping screws are
to be removed. Remove screws as directed.
Rotate the fan wheel by hand to ensure that the fan is
unrestricted and can rotate freely. Check for shipping
damage and fan obstructions. Adjust blower motor as
required.
Step 2 -- Position the Unit
Units must not be installed where they may be exposed to
potentially explosive or flmmnable atmosphere. If this
instruction is not followed exactly, a fire or explosion may
result, causing property damage, injury, or loss of life.
Select the unit position with the following points in mind:
• The unit should be installed on wall studs that are strong
enough to support the total weight of the unit, refrigerant
piping, and condensate.
• The unit should be mounted 8 ft or more from the floor
and if possible, centrally located on the wall from both
ends.
Proper clearance should be provided on the side and top
as shown in Fig. 4.
