FILTER-DRIERS

Liquid Line Filter Drier

The filter-driers used on Manitowoc ice machines are manufactured to Manitowoc specifications.

The difference between Manitowoc driers and off-the- shelf driers is in filtration. Manitowoc driers have dirt- retaining filtration, with fiberglass filters on both the inlet and outlet ends.

These filter-driers have a very high moisture removal capability and a good 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.

Listed below are the recommended O.E.M. field replacement driers:

SUCTION CLEAN-UP FILTER/DRIER

QF400/QC700/QF800

Contaminated systems must have a suction line filter/ drier installed to remove contamination (See System Contamination Clean-Up Procedures). An access valve must be installed on the inlet side of the suction filter to allow pressure drop readings to be obtained.

Remote Models

Contact your local Manitowoc Distributor for suction filter capable of cleaning the system. The clean-up filter drier must have a minimum nominal capacity of 3 hp. After clean-up is complete (see System Contamination Clean- Up Procedures), remove clean-up filter drier and replace with new suction filter.

Important

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

Suction Line Filter

Remote condensing units have a suction line filter to trap particles introduced during field installation. The suction filter does not have acid or moisture removal capabilities.
