Warning: Use only genuine Gardner Denver air filter elements on Gardner Denver compressor units.

Warning: Do not oil this element. Do not wash in inflammable cleaning fluids. Do not use solvents other than water. Improper cleaning may damage the element.

Warning: Never operate the unit without the element. Never use elements that are damaged, ruptured or wet. Never use gaskets that won’t seal. Keep spare elements and gaskets on hand to reduce downtime. Store elements in a protected area free from damage, dirt and moisture. Handle all parts with care.

Remove the wing nut and pull out the filter element.

Visually inspect the element. If cleaning is not necessary, reinstall the filter element.

If the element requires cleaning, wash the element by soaking about 15 minutes in warm water with a mild non-sudsing detergent.

Rinse the element thoroughly with clean water; a hose may be used if the water pressure does not exceed 40 psig (2.8 bar).

Inspect the element for ruptures or cracks in the pleated media; replace the element if any are found.

Inspect the gasket on the bottom (outlet end) of the element; replace the entire element if the gasket is damaged.

Warning: Always wear eye and ear protection and stand clear of the discharge port when testing the relief valve to prevent injury.

Caution: Never paint, lubricate or alter a pressure relief valve. Do not plug vent or restrict discharge.

Danger: Operation of the unit with improper pressure relief valve setting can result in severe personal injury or machine damage. Ensure properly set valves are installed and maintained.

Check the pressure relief valve for proper operation.
