Oil Controls
The W-OLC controls the oil level in the compressor crankcase
with a oat operated valve and keeps the oil level at the
compressor manufacturer’s recommended level. It is a direct
replacement of popular competitive models.

• Universal mounting pattern for standard semi-
hermetic compressors
Specifications
• Maximum working pressure: 450 psi
• UL/CUL le number: SA8547

The Oil Level factory setting is in the middle of the Sight Glass at 30 PSI for the Oil Level
Control. Located on the top of the control is the seal cap. Remove this to adjust the oil level.
To adjust the stem, turn it clockwise and counterclockwise, respectively, to lower and raise
the stem. One can determine the adjustment needed from the OLC-2-4 Oil Level Chart. One
eighth of an inch increments are used to illustrate the oil level at a selection of differential
pressure conditions.
Unlike our Competitors Controls no damage will occur when attempting to adjust beyond 7
turns. Our Design has a hard Stop to prevent damage.
In the case of an unexpected system defrost or load increase, large amounts of oil will return
through the suction line. Consequently, the oil control will not be able to keep the oil level from
rising beyond the control point.
