Dual Oil Filters
On compressor units equipped with dual oil fi lters, only
one fi lter should be in operation at a time.

should be open. This will help minimize the sudden loss
of oil pressure when switching between oil fi lters for
servicing.
Refer to Oil Filter Replacement in Section 5 for further
