COMPRESSORS
Units are shipped with compressor mountings factory-
adjusted and ready for operation.
FILTERS
51 mm (2”) or 102 mm (4”) filters can be supplied with
each unit. 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 shut-
down. Minimum filter area and required sizes are
shown in Physical Data Table 5.
