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 stabilizes, 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 lubricant, then reinstall drain plug.
6.
Machine should then be run normally; however, total run time after the initial change out 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 change outs should be at normal intervals. (See
“Oil Change Interval” and
Figure 5-7, page 74).
OIL LEVEL GAUGE
(Figure 1-6, page 12 and Figure 5-6) 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.

OIL CHANGE INTERVAL
- Recommended oil change intervals are based on oil temperature. Figure 5-7,
shows how the change interval is affected by temperature.
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.
