For units without oil-level sight glasses, oil levels cannot be checked.
For units with oil-level sight glasses,
the oil level must
be monitored as part of schedule maintenance.
Be sure that the room temperature is within 4°F (2.2°C) and the relative humidity is within 10% of the unit-
nameplate values. Check the oil level after 30 minutes of compressor operation.
The oil level should be as near the middle of the sight glass as possible,
and in any case between 1/4 and 3/4 full.
If the oil level is incorrect after 30 minutes of compressor operation, contact a Dectron-certified technician.
