Section 7 Refrigeration System<br />
FILTER-DRIERS<br />
The filter-driers used on <strong>Manitowoc</strong> ice machines are<br />
manufactured to <strong>Manitowoc</strong> specifications.<br />
The difference between <strong>Manitowoc</strong> driers and off-theshelf<br />
driers is in filtration. <strong>Manitowoc</strong> driers have dirtretaining<br />
filtration, with fiberglass filters on both the inlet<br />
and outlet ends. This is very important because ice<br />
machines have a back-flushing action which takes place<br />
during every harvest cycle.<br />
These filter-driers have a very high moisture removal<br />
capability and a good acid removal capability.<br />
The size of the filter-drier is important. The refrigerant<br />
charge is critical. Using an improperly sized filter-drier<br />
will cause the ice machine to be improperly charged with<br />
refrigerant.<br />
Important<br />
Driers are covered as a warranty part. The drier<br />
must be replaced any time the system is opened for<br />
repairs.<br />
