Dual Oil Filters
On compressor units equipped with dual oil fi lters, only 
one fi lter should be in operation at a time.
NOTE
During operation, both oil fi lter outlet shut-off valves 
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
