If outdoor air intake will not be required on
units with bottom return air applications, the
damper assembly should still be mounted on
the side return air access panel, per the
instructions above, to insure moisture is not
drawn into the unit during operation. The cov-
ering over the mounting holes only need be
removed. Do not remove the opening cover.

CONDENSATE DRAIN

Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate
drain line from the one-inch NPT female connection on
the unit to an open drain.
NOTE: The condensate drain operates in a negative
pressure in the cabinet. The condensate drain
line MUST be trapped to provide proper drain-
age. See Figure 4.

COMPRESSORS

Units are shipped with compressor mountings factory-
adjusted and ready for operation.
Do not loosen compressor mounting bolts.

FILTERS

Two-inch filters are supplied with each unit, but units
can be converted easily to four-inch filters. Filters must
always be installed ahead of the evaporator coil and
must be kept clean or replaced with same size and
type. Dirty filters will reduce the capacity of the unit and
will result in frosted coils or safety shutdown. Minimum
filter area and required sizes are shown in Physical
Data Table 7.
