WARNING
Soak element in a mild detergent solution for 15 min-
utes. Do not soak more than 24 hours. Swish element
around in the solution to help remove dirt. Rinse ele-
ments from inside out with a gentle stream of water
(less than 40 psi) to remove all suds and dirt. Dry ele-
ment before reuse with warm air at less than 1600F
(710C). Do not use a light bulb to dry the element.
Inspect for holes and tears by looking through the ele-
ment toward a bright light. Check for damaged gas-
kets or dented metal parts. Do not reuse damaged ele-
ments. Protect element from dust and damage during
drying and storage.
Replace air filter after six cleanings. A cleaned filter will
have approximately 70% of the life of a new filter ele-
ment. A restricted filter element may not appear exces-
sively dirty.
