Did you wipe the sealing surface of the filter housing with a clean, lint-free rag?

Did you remove the replacement element from its protective package?

Warning: Ensure you are wearing appropriate PPE

Loosen temperature control valve element without exerting excess stress on oil piping

Remove faulty temperature control valve element

Start and load unit to check for proper discharge temperature control

Sign off on the valve element replacement

Run compressor in full load mode and at rated pressure. Does the L.E.D. Table display 'XX PSI'?

Is the warning light on and does the display say 'CHG SEPR ELEMENT'?

If the warning light is on and the display says 'CHG SEPR ELEMENT', proceed with the following steps. Otherwise, no maintenance is required.

Disconnect the scavenge hose at the tank.

Loosen the fitting that holds the scavenge tube into the tank and withdraw the tube assembly.

Disconnect blowdown valve from elbow in tank cover.

Use a suitable wrench and remove the bolts that hold the tank cover in position. Remove cover by lifting up and away.

Carefully lift the separator element up and out of the tank. Discard the faulty element.

Clean cooler cores if discharge air temperature is excessive or if unit shutdown occurs on high air temperature.

Visually check the outside of the cooler cores to be certain that a complete outside cleaning of the cooler is required. Frequently dirt, dust or other foreign material, may only need to be removed to remedy the problem.

When the cooler is covered with a combination of oil, grease or other heavy substances that may affect the unit’s cooling, then it is recommended that the cooler cores be thoroughly cleaned on the outside.

Flush the outside cooler core using a safety solvent.

Follow solvent manufacturer’s directions for proper use.

Inspect sheave grooves for foreign material or rubber build-up

Clean and degrease sheaves before installing new belts

Install new belts in the reverse order of disassembly

Ensure new belt is not pried or forced over the sheave grooves

Apply a force at the center of the sheave span using a tension gauge or other calibrated spring

Loosen the nut on the pivot bolt located on the left side (nearest the separator tank) on the airend if belt tension is incorrect
