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.
All return air must pass through the filters before entering
the unit. 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 in unit shutdowns. Air filter pressure drop
must not exceed 0.08 inches WC. When replacing the air
filters, a suitable air filter must be installed ahead of the
evaporator coil of the return air system. Refer to Table 1
for recommended filter sizes.

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 to Table 3 (page 27) 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. See Figure 4.
• Keep the unit in an upright position at all times.
The rigging must be located outside the units
center of gravity. Refer to Figures 12 - 14 (pages
22 - 27) for locating the center of gravity.
• All panels must be securely in place during
rigging and hoisting.
Minimum Clearance Requirements
R6GP units are certified as combination heating and
cooling equipment for outdoor installation only. Figure 5
(page 9) displays the minimum clearances to combustible
materials for both Downflow and Horizontal discharge.
R6GP units may be installed on non-combustible surfaces
when used with bottom supply and return air ducts.
Units may be installed on wood flooring or on Class A,
