If water is found in the oil, drain sufficient volume of oil until no visible water is found - the heavier water
will collect at the low elevations of the oil system, thus it will likely be expelled first. If this condition
persists, consider the following solutions to avoid water condensation in the compressor oil:
·
Make sure that the correct setting for the thermostatic mixing valve element is used - value is
stamped on valve body. Fixed speed packages typically use 55ºC elements and variable speed
packages use 70ºC elements.
·
If using a Fixed Speed unit, replace the standard 55°C element with the 70ºC one. Refer to the
segment on the Thermostatic Mixing Valve within this Section for further details.
OIL CHANGE INTERVAL
- Recommended oil change intervals are based on oil temperature - see
Figure 5-4, page 58 for typical trends for the standard lubricant (AEON 4000) and a synthetic lubricant
(AEON 9000SP). Consult GD for additional lubricant types available for your compressor.
When operating conditions are severe (very dusty, high humidity, etc.), it will be necessary to change the
oil more frequently. Operating conditions and the appearance of the drained oil must be surveyed and
the oil change intervals planned accordingly by the user. Gardner Denver offers a free oil analysis
program with the AEON lubricants, and we recommend a sample be sent in at 100 hours on a new unit.

DRAINING AND REFILLING THE OIL SYSTEM
- Always drain the complete system. Draining when the
oil is hot will help to prevent varnish deposits and carry away impurities.
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. Thoroughly drain oil system while hot
– refer to Compressor Illustration on Page 10 for location of
various drain points:
·
Drain oil from oil sump by opening the drain valve at its bottom. Close drain valve.
·
Drain oil from the air end by removing the G1-1/2
” plug at the bottom of the discharge
·
Drain oil from the oil cooler by removing the G3/4
” plug on the oil header. Replace the plug.
·
Remove and drain oil from the oil filter. Reinstall the used filter. CAUTION - If the drained oil
and/or oil filter element is contaminated, discontinue this procedure and follow instead the
"Lubricant Change Procedure" listed on page 55.
4. Replace both used oil filter and air/oil separator element with new ones.
·
Remove each spin-on element.
·
Clean each gasket face of the filter body.
·
Coat each new element gasket with clean lubricant used in the unit
·
Screw each new element on the filter body and tighten by hand. Tighten 1/2 turn more after
gasket makes contact. DO NOT OVERTIGHTEN ELEMENT.
5. Wipe away all dirt around the oil filler plug.
6. Remove the oil filler plug and add oil as required to return the oil level to the full marker on the gauge.
