and soak filter element about 15 minutes. Refer to
directions on filter cleaner carton for complete
information.
B. After soaking filter for 15 minutes, rinse it with
clear water. Maximum water pressure must not
exceed 40 psi to prevent damage to the filter
element. Rinse filter from clean side to dirty to side.

(160F ) max), or allow element to air-dry. Do not
use a 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" from filter and
move nozzle up and down while rotating the filter
element. Inspect for holes and tears by looking
through the filter toward a bright light.
