Installation of the Filter and Filter / Drier
1. Before performing a refrigerant recovery, always inspect and clean the filter screen in the inlet fitting on
the RG6000 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.
Promax also strongly recommends using an in-line filter / drier (p/n 100343) in the inlet line.

CAUTION : To prevent personal injury, disconnect the RG6000 from the power supply before
performing maintenance.
Burned-out System
1. Use two high-acid capacity lter / driers in series when recovering from a “burned-out” system. Promax
recommends Alco type EK-162-F or Sporlan type C-162-F lters.
When you have nished recovering from the system, ush the RG6000 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 RG6000 of any residual refrigerant and purge it with dry nitrogen before
putting it in storage for a long period of time.
