protective equipment (goggles/shield, gloves, etc.).
1.
Hold nozzle at least 1 in. (25 mm) 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 dust no longer blows out.
2.
Prepare a solution of five gal. warm water 80-110°F (27-43°C) and one cup of non-sudsing detergent
in a container large enough to submerge element (1).

Immerse element (1) completely in cleaning solution, swish for two minutes, soak element (1) for
15-20 min., then swish it around again to remove contaminants.

Remove element (1) from the solution and let drain.
5.
Rinse element (1) with cool water 35-80°F (2-27°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 (276 kPa). If the clean side of
element (1) was contaminated during soak cycle, rinse from both sides.
CAUTION
Do not use compressed air to speed drying time or damage to
element may result.
