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.
