Note that repeated addition of oil between oil changes may indicate excessive oil carry-over and should
be investigated.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
top of the measuring rod
Use only CLEAN containers and funnels to avoid contamination of oil. Provide
for clean storage of oils. Changing the oil will be of little benefit if done in a
careless manner
OIL CHANGE INTERVAL
– The AEON 9000SP Synthetic Lubricating Coolant shall be changed every
8000 hours of operation or as prescribed by the results of an oil analysis, whichever comes first. Note
that severe operating conditions (e.g., very dusty, high humidity, etc.), may require more frequent oil
changes.
Gardner Denver offers a free oil analysis program with our AEON 9000SP lubricant. The first sample
from a new unit should be sent in between 40-100 hours of operation.
DRAINING AND CLEANING OIL SYSTEM
- 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 the following
method: (See Figure 5-1, page 42.
1.
Be sure the unit is completely off and oil sump is depressurized.
2.
Disconnect, lockout and tagout the power supply to the compressor package.
3.
Close (if provided by user) valve isolating compressor package from air system.
4.
Remove fill plug (1) and drain valve (3) to evacuate oil.
5.
Close drain valve (3), add oil up to top of measuring rod, and replace fill plug.
6.
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. Inspect the oil separator element for dirt accumulation;
replace if necessary. If a varnish deposit exists, contact the factory for recommendations for
removal of the deposit and prevention of varnish.
