Washing Method
A. Prepare solution of filter cleaner and water. Soak
filter element about 15 minutes. Refer to directions
on filter cleaner carton for complete information.

light bulb to dry the filter element because damage
could result.
Compressed Air Method
A. Blow compressed air from inside to the outside of
dry filter element. Do not exceed 100 psi to prevent
damage to the element.
B. Keep air hose nozzle at least 2 inches (5 cm) from
the filter. Move nozzle up and down while rotating the
filter element. Inspect for holes and tears by looking
through the filter toward a bright light.

ping damage. Check sealing end of filter. Do not install
a damaged filter.
