drain the moisture and correct the condition causing
the accumulation. See “Compressor Oil System
Check,” page 50 and “Thermal Control (Thermostatic
Mixing) Valve,” page 46.
OIL CHANGE INTERVAL – Recommended oil change
intervals are based on oil temperature (see
FIGURE 5–3).
When operating conditions are severe (very dusty, high
humidity, etc.), it will be necessary to change the oil
more frequently. Operating conditions and the appear-
ance of the drained oil must be surveyed and the oil
change intervals planned accordingly by the user. A
good lubricant analysis program is helpful in planning
the change interval.
Change the oil filter every 1000 hours.
DRAINING AND CLEANING OIL SYSTEM
Air/oil under pressure will cause
severe personal injury or death. Shut
down compressor, relieve system of
all pressure, disconnect, tag and
lockout power supply to the starter
before removing valves, caps, plugs,
fittings, bolts, and filters.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.
Always drain the complete system. Draining when the
oil is hot will help to prevent varnish deposits and carry
away impurities.
To drain the system, use one of the following methods:
1. If the unit is not elevated high enough to use the
oil reservoir drain line to drain oil, a small hand,
electric or air operated pump should be used to
drain reservoir through the oil filler opening or from
the drain valve.
2. If the unit is elevated so that the oil reservoir drain
can be used, empty the oil reservoir through the
drain valve to a suitable container or sump.
3. If the drained oil and/or the oil filter element are
contaminated with dirt, flush the entire system:
reservoir, oil cooler, mixing valve and lines.
4. Inspect the oil separator elements for dirt accu-
mulation; replace if necessary. If a varnish de-
posit exists, contact the factory for recommen-
dations for removal of the deposit and
prevention of varnish.
