side of the filter element. Holding nozzle about six
inches away from element, move nozzle up and down,
rotating element until no dust is visually being removed
(approxi-mately 10 minutes). Direct air perpendicularly
to pleats using 100 psi maximum air pres-sure. Do not
damage element with the air flow from nozzle.
Filter element can be cleaned by washing in water
cleaner to 1 gallon of water. For best mixing results use
a small amount of cool tap water, then add to warm (70°
(100°F) the solution, the better the cleaning. Soak
element for 15 minutes, then rotate element back and
forth with clean water. If a hose is used to wash or rinse
the filter, be careful not to rupture the paper with the
water jet. Rinse the filter element until drain water be-
comes clear. Proper rinsing is very important. Let filter
element air dry completely before using. Do not use
compressed air for drying.
