FIGURE 5–4 – OIL LEVEL GAUGE
Material Safety Sheets (MSDS) are available for all
AEON lubricants from your authorized Gardner Denver
distributor or by calling 217–222–5400.
OIL LEVEL GAUGE (FIGURE 1–3, page 3 and
FIGURE 5–4) indicates the amount of oil in the oil res-
ervoir. Read oil level only when unit is on. In operation
the oil level will fluctuate as the compressor loads and
unloads. Add oil only when the oil is at the bottom of
the red range on the gauge as read when the compres-
sor is on. Drain oil only when the oil level is above the
center of the green range on the gauge as read when
the compressor is on.
MOISTURE IN THE OIL SYSTEM – In normal humid-
ity and with normal operating temperatures and pres-
sures, the thermal mixing valve controls the oil temper-
ature 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 detri-
mental 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 33 and “Thermal Control (Thermostatic
Mixing) Valve,” page 32.
OIL CHANGE INTERVAL – Recommended oil change
intervals are based on oil temperature. FIGURE 5–3,
page 29, shows how the change interval is affected by
temperature.
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.

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.
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. In-
spect the oil separator elements for dirt accumula-
tion; replace if necessary. If a varnish deposit ex-
ists, contact the factory for recommendations for
removal of the deposit and prevention of varnish.
FILLING OIL RESERVOIR
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.
