Remove the Retaining Ring from the groove
1. Lift the tabbed end of the retaining ring up and out
of the stainless steel groove in the shell and then
away from the head so that it rests in the end margin
of the vessel. This is best accomplished by using
TM
CodeLine Removal Tool, part number 50303, which
is available from your supplier. This can also be
accomplished using a screwdriver and a pair of pliers
if the tool is not readily available.
With the removal tool the retaining ring can be
lifted upward by simply rotating the tool
counterclockwise after inserting it over the tab on
the retaining ring (Use the smaller hole). Hold the
tool flat against the end margin and parallel to the
vessel bore. It is then possible to pull the end of the
retaining ring straight out. The retaining ring may
snap back into the groove if this alignment is not
closely adhered to. If the retaining ring is difficult
to remove, try soaking with a release agent such as
TM 0TM
LPS or WD4 , being careful to avoid any
contamination of a membrane element.
Retaining Ring Removal Tool
When using screwdriver and pliers, pry the tabbed
end of the retaining ring out of the stainless steel
groove with the tip of the screwdriver. Once the end
of the retaining ring is clear of the groove, grab the
tab with the pliers and pull towards the end of the
vessel until the end of the ring is resting in the end
margin of the shell.

Opening the Vessel...

Remove the 4” retaining ring from the stainless steel
groove in the shell by rotating your finger behind the
ring as it continues to exit the groove.
2.
Removal of Retaining Ring
Once the retaining ring has been removed, examine
the area for burrs or dings which could damage the
TM
head or membrane. If necessary, use ScotchBrite
or 600 grade sandpaper to smooth the area.
3.
Removing Head Assembly
Using a mallet, tap the head assembly lightly. Do not
use a metal component to tap the head assembly.
1.
Thread a ½” O.D. Engineering Thermoplastic pipe
approximately 1 feet long into the permeate port.
2.
Carefully rock the head assembly back and forth to
release the seal (care should be taken to avoid too
much stress on the product port threads).
3.
Once the Plug seal is broken, pull straight outward to
remove the head assembly from the vessel.
4.
Remove and discard plug seal, taking care not
to scratch or otherwise damage the sealing
surfaces.
5.
Removing the head assembly
Repeat same procedure for opposite end of the
vessel.
6.
As soon as possible after removal, disassemble
and check all head components, as described in
Rebuilding the Head and Refurbishing Parts.

Replacing Elements
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
TM
manufacturer or CodeLine for clarification.
To replace elements, proceed as follows.
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.
Removing Elements
Remove heads from both ends of vessels as
described in Opening the Vessel.
Push element out of vessel from the upstream
end.

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
1.
CAUTION
When lubricating the vessel chamfer,
wear protective gloves or finger cots to
prevent cuts or penetration of
fiberglass.
Check that all required elements are ready for assem-
bly, with no dings or other damage which could
scratch the inside of the vessel.
2.
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
TM
and work a fresh, thin film of Parker-Super-O-Lube
silicon lubricant into the shell area behind the retaining
ring groove and approx. ½”into the vessel I.D. .
3.
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.
4.
Installation of the End Plug Assembly
into the vessel
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.
5.
Inserting Retaining Ring into the groove

Closing the Vessel
Page 6 of 9
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.
6.
Insert each element with the brine seal (typically a
U-cup seat) installed on the upstream end with its
lip facing upstream.
8.
Install the interconnectors between multiple elements
as each succeeding element is installed.
9.
Push each element downstream into the shell as it is
installed until the element is fully engaged with the
downstream head. If the elements are hard to push,
make sure the brine seal is properly installed and you
are pushing from the upstream end. When all the
elements are fully inserted into the vessel, install the
upstream head as described in paragraphs 4 through
6 on page 5 & 6.
10.
CAUTION
System malfunctions and element damage
may result if elements are
installed in the wrong direction.
NOTE
On some systems it may be easier to install
the piping connections before the head
is installed.
If so, please proceed with Steps 10 & 11.
Retaining ring seated in the grooove
Reconnect piping to vessel as described in Remaking
Pipe Connection to Eng Plug on page 9.
11.
Pressurize the vessel. Inspect for leaks at connections
to the vessel and all around the vessel itself. If any
leaks occur, release pressure from the vessel and
tighten the fittings as necessary. Then pressurize
vessel and check for leaks again.
12.
CAUTION
DO NOT tolerate any leaks. Leaks can
result in corrosion and eventual
catastrophic vessel failure.
WARNING
Any remaining lubricant should be cleaned
from the vessel bore before applying fresh
lubricant. Glycerine is a commercially
available lubricant that will not foul the
membranes
Lubricate element seals sparingly with the element
manufacturers recommended lubricant or with
glycerine.
