NOTE
Check the vacuator valve to be sure it is not damaged
or plugged. Be sure the cup joint at the end is sealing
properly.
4. Remove the element and inspect it by placing a bright
light inside. Rotate the element slowly and inspect for any
rupture, holes or damaged gaskets; replace as required.
5. If the service indicator flag reaches the top of the indica-
tor, the element should be cleaned (or replaced) using air or
water as follows:
A. Direct air pressure at the pleated paper inside of the ele-
ment. Keep the nozzle at least one inch from the pleated
paper. Move the nozzle up and down while rotating the
element. Air pressure must not exceed 100 psi.
B. Soak the element for 15 minutes or more in a cleaner
and water solution. Rinse until the water is clear; maxi-
mum water pressure 40 psi. Air dry or use warm flow-
ing air not to exceed 160F. Do not use compressed air
