Figure 5-6 - Oil Level Gauge; Figure 5-7 - Oil Change Interval - Gardner Denver AirSmart EAU99T Operating And Service Manual

OIL LEVEL GAUGE (Figure 1-2, page 10 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 AEON lubricants. The first sample from a new unit should be sent in after 100 hours.
