OIL LEVEL GAUGE
(Figure 5-4, page 57) - The oil level gauge indicates the amount of oil in the air/oil
reservoir. Read oil level only when the unit is shut down and the air/oil mixture has separated. Add oil
only when the oil level is below the min. range on the site glass. Drain oil only when the oil level is above
the max. range on the site glass.

MOISTURE IN THE OIL SYSTEM
- In normal humidity and with normal operating temperatures and
pressures, the thermal mixing valve controls the oil temperature and prevents moisture contamination of
the oil. Unusual cooling of the oil reservoir, short loaded cycle in high humidity or malfunctions of the
thermal valve may result in moisture in the oil system which is detrimental to compressor lubrication and
could cause oil carryover. If moisture is observed in the oil reservoir, drain the moisture and correct the
condition causing the accumulation.
See “Compressor Oil System Check”, page 61 and “Thermal Control Valve", page 59.
COMPRESSOR OIL FILTER
(Figure 1-2, page 10 and Figure 5-5, page 58)
-
This replaceable element
filter is a vital part in maintaining a trouble-free compressor, since it removes dirt and abrasives from the
circulated oil.
Improper oil filter maintenance will cause damage to equipment. Replace filter
element every 1000 hours of operation. More frequent replacement could be
required depending on operating conditions. A filter element left in service too
long may damage equipment.
Use only the replacement element shown on the filter tag or refer to the parts list for the part number. Use
the following procedure to replace the filter element. Do not disturb the piping.
