Replacing the filter elements
Replace the filter elements if the pressure difference be-
tween the inlet and outlet exceeds 20 psig (1.4 bar) or after
six months of operation, whichever occurs first.
Service steps
1. Close the inlet valve for the filter bank.
2. Unscrew the filter bowls slightly to relieve pressure.
Notes
•
If you can't remove bowls by hand, use a strap or
band wrench at the top of the bowl
only
. Avoid ex-
cessive pressure to the side of the bowl.
•
A small amount of water will spill when the filter
bowls are removed. A shallow drip pan under the
filter will minimize clean-up.
3. Remove the filter bowl and elements together. Remove
and discard the filter elements. Inspect the contents of
the bowls. A change in water quality, pump housing, or
impeller deterioration, or a missing or damaged up-
stream filter, can sometimes be detected early by in-
specting the filter bowls and elements.
4. Clean the bowls and fill with fresh water.
Install the new elements in the bowls, and then install on
the filter heads. Seal rings, provided with the elements,
seal the elements to the heads. Lubricate the rings with
food-grade grease. Make sure the filter elements are in-
stalled on the correct filter heads; look for the markings
to make sure.
5. Make sure the seal ring is in place, then tighten each
bowl hand tight on the filter bank head.
6. Open the inlet valve. Check for leaks. Bleed air from the
filters using the bleed valve.
7. Run the intensifier pump for 5 minutes at low pressure
with the cutting nozzle open to purge any air from the
system. Failure to do so could damage the high-pressure
seals.
