Requirements and procedures vary by location. Follow
your local laws governing the recovery, evacuation
and charging of equipment that contains propane
refrigerant.
LIQUID LINE FILTER-DRIERS
The filter-driers used on Manitowoc ice machines are
manufactured to Manitowoc specifications.
The difference between a Manitowoc drier and an off-
the-shelf drier is in filtration. A Manitowoc drier has
dirt-retaining filtration, with 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.
A Manitowoc filter-drier has high moisture and acid
removal capability.
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.
TOTAL SYSTEM REFRIGERANT CHARGE
NOTE: All machines listed use R-290 refrigerant - This
information is for reference only. Refer to the ice
machine serial number tag to verify the system
charge. Serial plate information overrides information

Driers are covered as a warranty part. The drier
must be replaced any time the system is opened for
repairs.
