General information
The 40E30N RO Pressure Vessel is designed for continuous, long-term use as housing for reverse osmosis in typical
commercial water treatment systems. Models are available for 300 psi. The 40E Series vessels are designed to
accommodate any make of 4-inch nominal diameter spiral-wound element with a 3/4” diameter male product water
tube. The fiberglass shell can be damaged by rigid clamping, impact, scratches or abrasion. Metal parts must be
maintained free of corrosion to eliminate potentially unsafe conditions due to corrosion. The information and
guidelines incorporated in this User’s Guide are intended only as a supplement to good industrial practice. Full
responsibility for correct operation and maintenance of vessel remains with the user. This guide should be used in
conjunction with drawing number 518016. When properly installed and maintained, Model 40E30N vessels can be
expected to provide safe operation over a long service life.

Installation
Regardless of when or by whom your vessel may have been installed, there are a few quick checks you should
make before use. Check that each vessel is:
Mounted with compliant material (Polyurethane saddle) between the fiberglass shell and any rigid frame.
Free to expand under pressure - shell not clamped rigidly in place, no rigid piping connections to port fittings.
Not used in any way to support other components such as piping, manifolds hanging from ports.

Opening the vessel
Contamination removal
Metal oxidation products and mineral deposits
can interfere with vessel disassembly. Remove
all foreign matter from both ends of vessel as
follows:
1. Remove contaminants using a small wire
brush or suitable abrasive (such as medium-
grade ScotchBriteTM).
2. Flush away loosened deposits with clean
water.
Cleaning inside the vessel
Removing the head
40E30N head assembly is shown in Figure 1 at
page 3
Remove head as follows:
Disconnect permeate piping and the feet
concentrate piping
1. Disconnect permeate piping as required at
nearest convenient joint, being careful not
to place undue stress on the threaded
connections of the plastic permeate port(s)
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 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 LPSTM or WD40TM,
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.
2. Remove the 4” retaining ring from the
stainless steel groove in the shell by rotating
WARNING: Relieve pressure from vessel
before beginning this procedure.
CAUTION: DO NOT tap on fittings as this
could damage the ports.

your finger behind the ring as it continues to
exit the groove.
Removal of retaining ring
3. Once the retaining ring has been removed,
examine the area for burrs or dings which
could damage the head or membrane. If
necessary, use ScotchBriteTM or 600 grade
sandpaper to smooth the area.
Removing head assembly
1. Using a mallet, tap the head assembly
lightly. Do not use a metal component to tap
the head assembly.
2. Thread a ½” O.D. Engineering Thermoplastic
pipe approximately 1 feet long into the
permeate port.
3. 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).
4. Once the Plug seal is broken, pull straight
outward to remove the head assembly from
the vessel.
5. Remove and discard plug seal, taking care
not to scratch or otherwise damage the
sealing surfaces.
Removing the head assembly
6. Repeat same procedure for opposite end of
the vessel.
7. 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
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-LubeTM 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.

Closing the vessel
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.
Retaining ring seated in the groove
7. Lubricate element seals sparingly with the
element manufacturers recommended
lubricant or with glycerin.
8. Insert each element with the brine seal
(typically a U-cup seat) installed on the
upstream end with its lip facing upstream.
9. Install the interconnectors between multiple
elements as each succeeding element is
installed.
10. 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.
11. Reconnect piping to vessel as described in
Remaking Pipe Connection to Eng Plug.
12. 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.
WARNING: Any remaining lubricant should
be cleaned from the vessel bore before
applying fresh lubricant. Glycerin is a
commercially available lubricant that will not
foul the membranes.
CAUTION: DO NOT tolerate any leaks. Leaks
can result in corrosion and eventual
catastrophic vessel failure.
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.

Refurbishing parts
Inspecting parts
Plastic parts: examine for cracking, softening or
discoloring. This may indicate chemical attack of
the material. Defective parts must be replaced.
Alternate material may be required. Contact
your supplier or Codeline for assistance.
Metal parts: check for corrosion, scratches,
dents, cracks or other damages to insert ring
and spiral retaining ring.
Other parts: examine for any damage, such as
gouges, chips or cracks that could affect
structural strength or sealing characteristics. The
following are some examples of defects that
may require replacement of the affected part.
End plug:
cracked, discolored, sealing areas damaged
(chipped or gouged), port threads stripped
or cross-threaded.
Spiral Retaining rings: are the sole means of
end plug retention. Parts bent, corroded,
cracked or damaged in any way must not be
used. Carefully check for hairline cracks.
Refurbishing shell
1. Using a fine wire brush, remove any large
deposits from locking ring groove in the
shell.
2. Using a medium or finer grade of
ScotchBriteTM and mild soap solution, clean
the inside of the vessel at least 4 inches in
from each end. Take care not to damage
feed/concentrate port and its respective
seal.
3. Use clean water to rinse away all loosened
deposits and soap residue.
4. Examine inside of vessel for scratches,
gouges, or other imperfections that could
prevent proper sealing. If such areas exist
and leaks are observed when the vessel is
placed back in service, the shell may need to
be replaced.
Refurbishing other parts
1. Remove any large deposit from metal parts
using a wire brush.
2. Scrub the entire surface with medium grade
ScotchBriteTM until all contaminants are
removed.
3. Rinse parts clean with fresh water and dry.
4. Inspect all parts for serviceability as
specified above.
Part replacement
Replace all parts that cannot be restored to as-
new condition.
Replace any parts showing signs of structural
damage or corrosion.
Seals should be replaced as necessary each time
the vessel is serviced. Any parts that need to be
replaced are available from your supplier or
from Codeline.
CAUTION: Use of components damaged by
corrosion can cause catastrophic failure.
