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
One-inch or two-inch 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 7.
