COMPRESSORS
Units are shipped with compressor mountings factory-
adjusted and ready for operation.
Units with scroll compressors have a shipping bracket
which must be removed after the unit is set in place.
See Figure 2.
FILTERS
Filters supplied with each unit can be 25 mm (1”) or 51
mm (2”) in width. 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 8.
