FLUID FILTER ELEMENT REPLACEMENT

Use a wrench to remove the filter canister.

Remove and dispose of the filter element properly.

NOTE: Dispose of fluids in accordance with applicable federal, state, and local regulations.

Clean the gasket seating surface.

Apply a light film of fluid to the element seal.

CAUTION: Do not mix different types of lubricants. Mixing lubricants can cause malfunctions or compressor damage and will void the compressor’s warranty.

Sullair encourages its customers to participate in a fluid analysis program with the fluid suppliers. In some cases, the analysis results suggest a fluid change interval that differs from the User Manual. Contact a Sullair representative for details.

When performing a fluid change or topping off the fill, the proper level should be at half of the sight glass, with the machine off.

Mixing, changing, or adding other lubricants within the compressor unit may void the air-end warranty.

Change the compressor fluid using instructions shown in the Lubrication Guide.

Refer to Figure 3-1 for the fluid fill port location.
