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 (70ºC)for the thermostatic mixing valve element is used -
value is stamped on valve body.
OIL CHANGE INTERVAL
- Recommended oil change intervals are based on oil temperature-see Figure
5 - 4 Figure 5 - 4, page 41 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 system is hot:
·
Drain oil from air end and cooler by removing single drain plug at the bottom of the oil core tank -
see Figure 1-3 page 10 for details. Make sure to provide a suitable pan to catch the 2gal oil
charge. Reinstall the drain plug after drainage.
·
If the drained oil and/or oil filter element is contaminated, discontinue this procedure and follow
instead the "Lubricant Change Procedure" listed on page 50.
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
