Check the oil level at the sight glass on the front of the WHASP Tank.
Continue adding oil until the level is correct.
Reinstall the fill cap.
Clean the WHASP Tank around the coalescing filter to prevent
contamination.
Remove the spin on coalescing filter by turning it counterclockwise
(Figure 41).
Clean the gasket sealing surface and inspect it for damage. The surface
must be free of old gasket material and smooth to ensure a good seal
(Figure 41).
Apply a thin coat of compressor oil to the rubber gasket on the new
coalescing filter.
Spin the new filter onto the threaded nipple until the gasket contacts the
sealing surface on the tank, then tighten the filter an additional 3/4 to 1
turn to seat the gasket.

Once the system has sat for 5 minutes, check the oil level through the
sight glass. The level must be between the
“MIN” and “MAX” level
indicators.
Verify there are no oil leaks.
Inspect sealing
