Cleaning the D.E. grid cassette:
Step 19
Align wiper rod to fit through hole in top of
the cover. Place the cover on the filter body
and press firmly downward until the cover
comes to a stop against the filter body.
TIP: It is easier to replace the filter cover if the
air bleed valve is open.
Step 20
Clean the threads of the Ring-Lok nut and the
threads on the filter body with water or a
cloth. Place the Ring-Lok nut on the filter and
tighten to the “built-in stops.” Be sure that the
yellow safety latch is engaged.
Step 21
Tighten air bleed valve into cover . Screw
wiper handle on to exposed threads of wiper
rod.
If the Ring-Lok nut is not tightened to built-in
stops, the filter cover may blow off causing
injury or property damage.
You are now ready to perform the system start-up (see pages 7-8).
