Replacing elements
The following procedures are provided for
information only. Elements should be installed in
accordance with the element manufacturer’s
recommendations.
Where conflicts exist, contact the element
manufacturer or Codeline for clarification.
To replace elements, proceed as follows.
Removing Elements
1. Remove heads from both ends of vessels as
described in Opening the Vessel.
2. Push element out of vessel from the
upstream end.
3. For multi-element vessels, remove the
interconnectors 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 conditions see section on
inspecting parts at pg.10).
2. Check that all required elements are ready
for assembly, 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 of burrs, sharp edges or other
damage. Remove any residual lubricant from
the vessel bore and work a fresh, thin film of
Parker-Super-O-Lube
TM
silicon lubricant into
the shell area behind the retaining ring
groove and approx. ½” into the vessel I.D.
4. Orient end plug port into desired position
and push plug fully into vessel. A sharp,
forceful thrust may be needed to enter plug
seal into the vessel bore.
Installation of the End Plug Assembly into the vessel
5. Carefully insert retaining ring into its groove.
This is done by inserting the lead end of the
spiral retaining ring (the non-bent tab end)
into the retaining ring groove located in the
shell, and slowly pushing the remaining
turns into the shell.
Inserting Retaining Ring into the groove
CAUTION: When lubricating the vessel
chamfer, wear protective gloves or finger
cots to prevent cuts or penetration of
fiberglass.
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.
