4.1 Routine Maintenance
Perform the maintenance procedures in Table 3 at least once per year or more often if needed.
Oil consumption varies by application and during initial operation. Monitor the oil level routinely to
determine a consistent pattern of actual consumption.
Table 3 Maintenance summary
Components Maintenance Reason For details, see:
Lubrication
& Cooling
System
• Monitor and check the oil level.
A low oil level or loss
of oil in the system will
result in overheating or
mechanical failure.
A high oil level may result
in excessive oil carryover
and oil discharge from
the Compressor Module
when the Compressors
are turned off.
4.3 - Checking
the Oil Level
(page 18)
• Add oil as needed.
4.5.1 - Topping
Off the Oil Level
(page 19)
• Change oil annually.
Note: Some applications may require more
frequent service.
4.5.2 - Changing
the Oil
(page 20)
• Check the condition of the lubricant
periodically. Normal color is clear or light
gray.

• Change the oil filter (if equipped) annually
or as required.

Gas Inlet
System
• Inspect and clean the inlet screen annually
or more often as needed.
A restricted inlet screen
will result in reduced flow.

Second-
Stage
Separator
System
• Inspect and clean the scavenge line orifice
annually or more often as needed.
A restricted scavenge
line orifice will result in
excessive oil carryover.
4.7 - Servicing
the Scavenge
Line Orifice
(page 22)
• Change the second-stage oil separator
element annually or more often if
contaminated.
Note: Some applications may require more
frequent service.
A dirty or plugged
separator element will
result in excessive oil
carryover.
