UNIT INSTALLATION
Packaging Removal
Remove the shipping carton and User's Manual from the
equipment. Set aside the 13" x 2" PVCpipe for later use
when installing the heat exchanger condensate drain
and vent kit.
Rigging & 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 7 (page 23) 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 7 (page 23)
for locating the center of gravity.
• All panels must be securely in place during
rigging and hoisting.
Clearances to Combustible Materials
These units are certified as combination heating and
cooling equipment for outdoor ground level installations.
• Sufficient clearance for unobstructed airflow through
the outdoor coil must also be maintained in order to
achieve rated performance. See page 5 for information
about locating the equipment.
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 1 (page 5).
• A suitable mounting pad must be provided and be
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. See Figure 3.
• Remove and discard the horizontal Supply and Return
duct covers located on the rear of the unit. Form duct
attachment flanges by bending the sheet metal outward
90 degrees along the perforated lines.
• Firmly attach ductwork directly to these flanges with
screws or other approved mechanical connections and
not to the Supply/Return air panels to avoid damage to
internal components of the equipment. Use approved
duct sealing methods to ensure an air and watertight
seal is achieved.

Condensate Drain (Air Conditioning)
Air conditioning condensate is removed from the unit
through the 3/4" female pipe fitting located on the front
side of the unit. See Figure 4.
Install a 2 inch condensate trap in the drain line of the
same size and prime with water. When connecting rigid
drain line, hold the female fitting with a wrench to prevent
twisting. Do not over tighten! Refer to local codes and
restrictions for proper condensate disposal requirements.
