Liquid Line Filter-Driers; Suction Filter - Manitowoc QuietQube Series Technician's Handbook

LIQUID LINE FILTER-DRIERS

The filter-driers used on Manitowoc ice machines are
manufactured to Manitowoc specifications. A Manitowoc
drier has dirt-retaining filtration, with fiberglass filters
on both the inlet and outlet ends. This is very important
because ice machines have a back-flushing action that
takes place during every Harvest cycle.
The size of the filter-drier is important. The refrigerant
charge is critical. Using an improperly sized filter-drier
will cause the ice machine to be improperly charged with
refrigerant.
Driers are covered as a warranty part. The drier must
be replaced any time the system is opened for repairs.

SUCTION FILTER

The suction filter on QuietQube® CVD condensing units
traps particulate only, and do not contain a desiccant. The
filter needs replacement when:
1. The pressure drop across the drier exceeds 2 psig.
2. A compressor is replaced.
3. Refrigeration system contains contaminants.
