Moisture In The Oil System - Gardner Denver EDF-KB Operating And Service Manual

– Dump oil from the filter and reinstall used fil-
ter.
2. Fill the system with a 50 percent charge of the new
lubricant:
– Start the machine and stay there to observe.
– Allow the machine to run about five minutes
at temperature, or until temperature stabi-
lizes, then shut down.
3. Thoroughly drain the machine.
4. Change to a new filter and separator.
5. Fill the system with a full charge of the new lubri-
cant, then reinstall drain plug.
6. Machine should then be run normally, however,
total run time after the initial changeout should be
50 percent of normal anticipated service life of the
new lubricant.
– Drain all lubricant from the system, change
the filter and separator, and replace with a full
charge of the new lubricant.
7. Subsequent lubricant changeouts should be at
normal intervals. (See "Oil Change Interval" and
chart below.)
Improper equipment
with use of synthetic lubricants will
damage equipment. Oil filter and oil
separator change intervals remain
the same as for AEON
Maintenance Schedule, page 43.
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.

OIL LEVEL GAUGE (FIGURE 1–6, page 3, and
FIGURE 5–4, page 33) indicates the amount of oil in
the oil reservoir. 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
compressor 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.

Mixing) Valve," page 35.

High temperature
cause damage to equipment or per-
sonal injury. Do not repeatedly restart
the unit after high temperature stops
operation. Find and correct the mal-
function before resuming operation.
All materials used in Gardner Denver
compressor units are compatible with
AEON 9000 SP Lubricating Coolant.
Use caution when selecting down-
stream components such as air line
lubricating bowls, gaskets and valve
trim.
AEON 9000 SP Synthetic Lubricant
is not compatible with low nitrile Buna
N or acrylic paints. AEON 9000 SP is
compatible with most air system
downstream components.
