High temperature operation can
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
R
compressor units are compatible with
AEON
t
9000 SP Lubricating Coolant.
Use caution when selecting down-
stream components such as air line
lubricating bowls, gaskets and valve
trim.
AEON
t
9000 SP Synthetic Lubricant
is not compatible with low nitrile Buna
N or acrylic paints. AEON
t
9000 SP is
compatible with most air system
downstream components.
Material Safety Sheets (MSDS) are available for all
AEON lubricants from your authorized Gardner Denver
distributor or by calling 217–222–5400.
COLD AMBIENT OPERATION – See “Installation for
Cold Weather Operation,” and FIGURE 2–3, page 9.
ADDITION OF OIL BETWEEN CHANGES must be
made when the oil level is below the center of the lower
sight gauge as read while the unit is completely off and
blown down, and the foam has settled out.
1.
Be sure the unit is completely off and that no air
pressure is in the oil reservoir.
2.
Disconnect, tag and lockout the power supply to
the starter.
3.
Wipe away all dirt around the oil filler plug.
4.
Remove the oil filler plug and add oil as required
to return the oil level to the bottom of the upper
sight gauge.
5.
Install oil filler plug, run and check for leaks.
DO NOT OVERFILL (you should not see oil in the up-
per sight gauge after running fully loaded and then
shutting down the machine and allowing the foam to
settle out). The quantity required to raise the oil level
from “ADD” to “FULL” is shown in FIGURE 5–2, page
27. Repeated addition of oil between oil changes may
indicate excessive oil carry–over and should be investi-
gated.
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.
Excessive oil carry–over can damage
equipment. Never fill oil reservoir
above the “FULL” marker.
OIL LEVEL SIGHT GAUGES (FIGURE 1–3, page 3)
indicate the amount of oil in the oil reservoir. Read oil
level when unit is shut off and the foam has settled out.
In operation the oil level will fluctuate as the compres-
sor loads and unloads.
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 32 and “Thermal Control (Thermostatic
Mixing) Valve,” page 31.
