Installation of the Filter and Filter / Drier
1. Before performing a refrigerant recovery, inspect and clean the filter screen in the inlet fitting on the
unit. Replace the filter screen (p/n SK-6001) if necessary. A filter screen greatly reduces the risk
of damage to the unit by preventing foreign material from entering the unit and the system being
serviced. Failure to use a filter screen will invalidate the warranty.
Also use an in-line filter / drier (p/n 100343) in the inlet line.

aintenance
CAUTION : To prevent personal injury, disconnect the unit from the power supply before
performing maintenance.
Burned-out System
1. Use two high-acid capacity filter / driers in series when recovering from a “burned-out” system. Promax
recommends Alco type EK-162-F or Sporlan type C-162-F filters.
When you have finished recovering from the system, flush the unit with a small amount of clean
refrigerant and refrigerant oil to purge any foreign substances left in the unit.
Storage
1. Empty refrigerant from the unit into a storage cylinder. Liquid refrigerant left in the unit’s condenser may
expand, causing damage to components.
2. Completely evacuate the unit of any residual refrigerant and purge it with dry nitrogen before putting it
in storage for a long period of time.
