Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the “FULL” marker.
OIL LEVEL GAUGE
(Figure 1-3, page 9) indicates the amount of oil in the oil reservoir. Read oil level
when unit is shut off and the foam has settled out. In operation the oil level will fluctuate as the
compressor loads and unloads. If oil can be seen in the lower sight gauge, the oil level is adequate.
MOISTURE IN THE OIL SYSTEM –
In environments with normal operating temperatures and pressures
and low relative humidity, the thermal mixing valve controls the oil temperature and prevents moisture
accumulation in the oil. Unusual cooling of the oil reservoir, light duty cycles, high humidity, gross
compressor over-sizing or malfunctions of the thermal mixing valve may result in moisture accumulation
which is detrimental to compressor lubrication and may cause excessive oil carryover in the lubricant or
compressor failure. Please note that the airend discharge temperature must be maintained a minimum of
10
°
F above the pressure dew point temperature in Figure 5-3 or 5-4, page 50
.
Failure to maintain the
discharge temperature will cause moisture formation and compressor damage. The compressor must be
observed to ensure that it is operating properly. The best method for detecting moisture is a disciplined
lubricant sampling analysis program every 2,000 hours of operation. If moisture is observed in the oil
reservoir, drain the moisture and correct the operating conditions to reduce moisture. See
“Thermal
Control (Thermostatic Mixing) Valve, page 54,
“Water Shutoff Valve”, page 53 and “Compressor Oil
System Check
”, page 56, for additional system considerations. If moisture accumulation is observed in
the lubricant, the best option is a higher temperature mixing valve, AEON 9000TH lubricating fluid and
setting the high discharge temperature shutdown to 240
°
F.
