Hold nozzle at least one inch away from element (1) and direct compressed air against clean side of
element (1) (in direction opposite to normal air flow). Move air stream up and down length of pleats
until you can not see dust being blown out.
Prepare a solution of five gallons warm water (80-110° F (26.7-43.3° C)) and approximately one cup
of non-sudsing detergent in a container large enough to submerge the element (1). Never use
gasoline or solvents of any kind to clean elements.
Immerse the element (1) completely in the cleaning solution. Swish for two minutes. Soak the
element in the cleaning solution for 15 to 20 minutes, then swish it around again to remove
contaminants.
Remove the element (1) from the solution and let it drain.
Rinse the element with cool water (35-80° F (1.7-26.7° C)) from clean side to dirty side (in direction
opposite to normal air flow) with a gentle stream of water (no more than 40 psi (275.8 kpa)). If the
clean side was contaminated during the soak cycle, rinse the element from both sides.
Air dry the element (1) at normal room temperature until completely dry. Usually overnight is ade-
quate, but temperature and humidity will effect drying time. If you use circulating air, do not exceed
180° F (82.2° C). Do not use compressed air to speed drying time, you will damage your element.
Reinspect the element (1) and discard if damaged. If it checks out O.K., mark the date of cleaning
on it.
