The 40E60 RO Pressure Vessel Housings are
designed to be used in water desalination systems. Any
make of 4 inch nominal diameter spiral wound ele
ment may be used. The vessels utilize a fiberglass
reinforced plastic shell for superior corrosion resis
tance. However, metallic parts of the vessel may be
subject to corrosion, which can result in an unsafe
condition. The fiberglass shell can be damaged by rigid
clamping, impact, scratches or abrasion.
The information and guidelines incorporated in this
User's Guide are intended only as a supplement to good
industrial practice. Full responsibility for correct opera
tion and maintenance of vessel remains with the user.
This guide should be used in conjunction with drawing
number 518017.
When properly installed and maintained, 40E60
vessels can be expected to provide safe operation over
a long service life.

Contamination Removal
Removing the Head
The head assembly is shown in figure 1.
Remove head as follows:
Opening The Vessel
.
Page 3 of 6
1. Disconnect permeate piping as required at
nearest convenient joint, being careful not to
place undue stress on the threaded
connections in the plastic end plug.
WARNING
DO NOT tap on fittings as this
could damage ports.
CAUTION
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
ScotchBrite).
2. Flush away loosened deposits with clean water.
2. Lift the tabbed end of the retaining ring up 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.
(User 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.
When using screwdriver and pliers, pry the tabbed
end of the retaining ring out of the stainless steel
groove with the tip of the screw driver. 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.
3. Remove the 4" retaining ring from stainless groove in
the shell by rotating your finger behind the ring as it
continues to exit the groove.
4. Once the retaining ring has been removed, examine
the area for burrs or dings which could damage the
head or membrane. If necessary, use ScotchBrite or
600 grade sandpaper to smooth the area.
5. Grasp the feed/concentrate port and pull the necessary
head assembly straight out. It may be necessary to
give a sharp forceful tug or to rock the head from side
to side in order to start the head moving. Take care
to avoid damaging the permeate port. It is made of
PVC or other engineering thermoplastic (occasionally
stainless steel or other metal) and is not designed to
withstand mistreatment.
6. Remove and discard plug seal, taking care not to
scratch or otherwise damage the sealing surfaces.
7. Repeat above procedures for opposite end of vessel.

Replacing Elements
The following procedures are provided for informa
tion only. Elements should be installed in accord
ance with the element manufacturer's recommen
dations. Where conflicts exist, contact the element
manufacturer or CodeLine for clarification. To
replace elements, proceed as follows.
Removing Elements
2. Push element(s) out of vessel from the upstream
end.
3. For multi element element vessels, remove the
interconnectors and retain for reinstallation
Inserting Elements
5. Install interconnectors between multiple elements
as each succeeding element is inserted.
6. Push each element downstream into shell as it is
installed until elements fully engage with the
downstream head. If elements are hard to push,
make sure the brine seal is properly installed and
you are pushing from the upstream end.
7. When all elements are installed, close the vessel
as described in the following section.
1.Ensure that element exterior and shell bore are
in clean, as new condition before proceeding
(See Refurbishing Shell, Page 6)
2.Reinstall head assembly at the downstream end
as described in losing the Vessel, with adapter
fitted (if required)
1. Remove heads from both ends of vessels as
described in Opening the Vessel.
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.
Note
3.Lubricate element seals sparingly with the manu
facturers recommended lubricant or with glycerine
(a commercially available lubricant that will not
foul elements)
DO NOT lubricate element seals with
a silicone-based material (such as
Parker Super O-lubeTM , the recom-
mended lubricant for end plug seals
CAUTION
4. Insert each element with the brine seal (typically a
u cup seal) installed on the upstream end with its lip
facing upstream.
System malfunctions and element
damage may result if elements are
installed in the wrong direction.
CAUTION

Product Bulletin 526004 Rev. A
Closing the Vessel
Prepare and install head assemblies as described
below.
1.Refurbish or replace head components as required
to ensure as new condition. (See refurbishing
Parts.) O rings should be replaced each time
2.Cover O rings with a thin, even layer of Parker
Super O LubeTM silicone lubricant or the lubricant
recommended by your supplier.
When lubricating vessel chamfer,
wear protective gloves or finger cots
to prevent cuts or penetration by
fiberglass
CAUTION
Glycerine is a commercially available
lubricant that will not foul elements.
However silicone lubricant is recom-
mended for this application
NOTE
3. Remove any residual lubricant from the vessel bore
and work a fresh, thin film of Parker Super O LubeTM
silicone lubricant into the lead in chamfer and an area
approximately 1/2 inch in width from the chamfer.
4. Install small O ring groove inside small end of
plastic end plug.
5.Install large O ring(s) in external groove(s) of end
plug. (Some plugs take two external O rings.)
6.Install adapters, if required, into end plugs. Insert
one end plug into downstream end of vessel. Using
both thumbs, apply equal pressure on opposite sides of
end plug to force plug into vessel so that steel bearing
ring slears retaining ring groove.
7. Carefully insert retaining ring into its groove. This is
done by inserting the lead end of the spiral retaining
ring (end without the bent tab) into the stainless steel
retaining ring groove located in the shell, and slowly
pushing the remaining turns into the shell.
8.Check that spiral retaining ring is fully seated in
groove. If it is not, remove and check for materials
causing the spiral ring not to fully seat.
9. Insert elements, then install upstream head, (with
adapter if required).
10. Reconnect piping to vessel, as described in Refur-
bishing Parts (Page 6)
11. If threading fittings into end plug, a oid
o ertightening. Hand tight plus approximately
1/4 turn should produce a satisfactory seal. If
leaks occur on pressurization, a small amount of
further tightening may be required.
12. Pressurize vessel. Inspect for leaks at connections
to the vessel and all around the vessel itself. If any
leaks occur, release pressure from vessel and tighten
fittings as necessary. then pressurize vessel and check
for leaks again.
DO NOT pressurize vessel without
element(s) properly installed.
Caution
DO NOT tolerate any leaks. Leaks
can result in corrosion and eventual
catastrophic vessel failure.
Caution

Plastic parts: examine for cracking, softening, or
discoloring. This may indicate chemical attack of the
material. Defective parts must be replaced. Alternate
materials may be required. Contact your supplier or
CodeLine for assistance.
Metal parts: check for corrosion, scratches, dents,
cracks or other damage to anodized surface of the
bearing plate, bearing ring and spiral locking ring.
Inspecting Parts
1. Using a fine wire brush, remove any large
deposits from locking ring groove in the vessel.
2. Using a medium or finer grade of ScotchBrite
and mild soap solution, clean the inside of the
vessel at least 4 inches in from each end.
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 ob
served when the vessel is placed back in service,
the shell may need to be replaced.
Seals should be replaced as necessary each time the
vessel is serviced. Any parts that need to be re
placed are available from your supplier or from
CodeLine.

CAUTION
1. Remove any large deposits from metal parts using
a wire brush.
2. Scrub the entire surface with medium grade
ScotchBrite until all contaminants are removed.
3. Rinse parts clean with fresh water and dry
Remaking Pipe Connections to End
Plug
1. Use a wire brush to remove all foreign matter from
threads on pipe fittings.
2. Apply non hardening thread sealant or TeflonTM
tape to fittings and install into end plug. Tighten
each fitting a maximum one quarter turn past hand
tight; the plastic end plug could be damaged if
fittings are overtightened.
3. Fit end plug and retaining ring as described in
losing the Vessel (page 5)
