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
Johnson Controls Unitary Products
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.
