The following procedures are provided for inform-
ation only. Elements should be installed in accord-
ance with the element manufacturer's recommend-
ations. Where conflicts exist, contact the element
manufacturer or Pentair Water for clarification.
To replace elements, proceed as follows.
Removing Elements
1. Remove heads from both ends of vessels as
described in Opening the Vessel.
NOTE
Always remove and install element in
the direction of feed flow. The feed
end (upstream end) is the end plumbed
most directly to the pump.
2. Push element out of vessel from the upstream
end.
3. For multi-element vessels, remove the inter-
connectors and retain for reinstallation.
Inserting Elements
1. Ensure that heads are available in clean, as-new
condition before proceeding. (If in doubt as to
head condition see section on inspecting parts,
page 9).
2. Check that all required elements are ready for assem-
bly, with no dings or other damage which could
scratch the inside of the vessel.
3. Check that the interior of the vessel is clean and free
o f b u r r s , s h a r p e d g e s o r o t h e r d a m a g e .
Remove any residual lubricant from the vessel bore
and work a fresh, thin film of Parker-Super O-Lube
silicon lubricant into the lead-in chamfer and an area
approximately ½ inch in from the chamfer
CAUTION
When lubricating the vessel chamfer,
wear protective gloves or finger cots to
prevent cuts or penetration of
fiberglass.

Replacing Elements
4. Install adapter if required into one end plug. At
downstream end of vessel, orient end plug
ports into desired position and push plug fully
into vessel. A sharp, forceful thrust may be
needed to enter plug seal into the vessel bore.
5. Carefully insert retaining ring into its groove.
This is done by inserting the lead end of the
spiral retaining ring (end without bent tab) into
the stainless steel retaining ring groove located
in the shell, and slowly pushing the remaining
turns into the shell.

6. Check that the spiral retaining ring is fully seated
in the groove. If it is not, remove and check for
foreign material that is causing the spiral ring not
to sit into the groove.
