Air Filter Requirements
WARNING:
Never operate the unit without a filter in place.
Dust and lint could accumulate on internal parts,
resulting in loss of efficiency, equipment damage
and possible fire. Replace disposable filters with
the same type and size.
= Air filter(s) are not supplied and must be installed Jn
the unit or in the return air system by the installer. Only
three phase units are equipped with an internal filter
rack assembly.
= If using an Economizer or Fresh Air Equipment, the
factory installed filter rack must be removed prior to
installation. See page 8 for removal instructions.
= All return air must pass through the filters before
entering the unit. Recommended filter sizes are listed in
Table 1. NOTE: It is important that all filters be kept clean
and replaced frequently to ensure proper operation of
unit. Dirty or clogged filters will reduce the efficiency
of the unit and result Jnunit shutdowns.
= Air filter pressure drop must not exceed 0.08 inches
WC. When replacing the air filters, a suitable air filter
must be installed upstream of the evaporator coil of
the return air system.
= Downflow installations require an internal filter
accessory kit to be installed.
= Horizontal installations require the air filter system be
installed in the return air ductwork.

AIR CONDiTiONER INSTALLATION
Packaging Removal
Remove the shipping carton and User's Manual from
the equipment. Take care not to damage the tubing
connections when removing the carton. For rooftop
installations, remove and discard the two supports
attached beneath the unit.
Rigging and Hoisting
WARNING:
To avoid the risk of property damage, personal
injury, or death, it is the rigger's responsibility
to ensure that whatever means are used to hoist
the unit are safe and adequate:
The lifting equipment must be adequate for the
load. Refer toTable 4 (page 14) for unit weights.
The unit must be lifted from the holes in the
base rails using cables or chains.
Spreader bars are required to protect the unit
and ensure even loading.
Keep the unit in an upright position at all times.
The rigging must be located outside the units
center of gravity. Refer to Figure 9 (page 14)
for locating the center of gravity.
All panels must be securely in place during
rigging and hoisting.
Minimum Clearance Requirements
P6SD units are certified as cooling equipment for
outdoor installation only. Figure 2 (page 6) displays the
minimum clearances to obstructions for both Downflow
and Horizontal discharge.
Units may be installed on wood flooring or on Class A,
B, or C roof covering material when used with bottom
supply and return air ducts. If using bottom discharge
with return air ducts, a roof curb must be installed prior
to unit installation. See Rigging and Hoisting section for
setting of the unit.
Ground Level
Ground level installations must be located according to
local building codes or ordinances and these requirements:
= Clearances must be in accordance with those shown
in Figure 2.
= A suitable mounting pad (Figure 3, page 8) must be
provided and separate from the building foundation.
The pad must be level to ensure proper condensate
disposal and strong enough to support the unit's weight.
The slab height must be a minimum of 2" (5cm) above
grade and with adequate drainage.
= Allow sufficient clearances for access to the internal
filter rack.
