1.0 DESCRIPTION
1.1 General Information and Principles of Operation
Your E-Series reverse osmosis (RO) machine is a durable piece of equipment which, with
proper care, will last for many years. These instructions give operating and maintenance
details vital to the sustained performance of the machine.
Reverse osmosis is the separation of one component of a solution from another component by
means of pressures exerted on a semipermeable membrane element. Removal of ionic, organ-
ic and suspended / dissolved impurities occurs during the RO process. Unlike a filter, which
separates by “normal” filtration, the General Electric (GE) Osmonics membrane element sep-
arates using a process called cross flow filtration. Feed water solution is separated into two
streams, permeate and concentrate, and collected from both sides of the membrane element. A
semipermeable RO membrane element, under sufficient pressure, allows passage of purified
water while rejecting and concentrating dissolved and suspended solids.
Figure 1.1
Normal Versus
Cross Flow Filtration
GE Osmonics manufactures a patented spiral-wound membrane element package, with a tur-
bulent flow design. This membrane element collects the purified water within a central tube,
the permeate tube (Figure 1.2, Membrane Element with Interconnectors and Figure 1.3, Cross
Sectional View of Membrane Element).

Some operating definitions are provided to help you further understand your machine:
Permeate Rate [Product Water Rate (Qp)] is the flow rate of purified water which has
passed through the membrane element and out of the membrane element housing;
expressed in gal/min (gpm) or gal/hr (gph) [in metric, liter/min (Lpm) or cubic
meters/hour (m3/h)]. Specified permeate rates are normally at 77ºF (25ºC).
Concentrate Rate [Waste Water Rate (Qc)] is the flow rate of water containing reject-
ed solids to drain in gpm or gph (Lpm or m3/h).
Feed Rate (Qf) is the flow rate of incoming water in gpm or gph (Lpm or m3/h).
Feedwater rate equals permeate rate plus concentrate rate.
Recovery equals permeate rate divided by feed rate and is expressed as a percentage.
For example, 33% recovery means that out of a given feed rate, 33% is produced as
purified water (permeate).
Concentration equals the Total Dissolved Solids (TDS) concentration of a solution
expressed as milligrams per liter (mg/L) or conductivity (microSiemens/cm).

Salt (Ionic) Rejection equals the percent of dissolved salt rejected by the membrane
element, calculated from an average concentration over the membrane.
Salt (Ionic) Passage equals (100% - rejection) or the percent of dissolved salts passed
through the membrane element.
An example of how to calculate salt rejection and recovery is given below:

Flow Description - The feed water passes through a replaceable 5-micron cartridge
pre-filter which removes bulk suspended solids. Filtered water then flows to the inlet con-
trol valve. This solenoid-controlled diaphragm valve is wired to the ON/OFF switch and
opens when the machine is turned ON, allowing water to flow to the pump inlet. When
the machine is turned off, the valve closes, preventing non-turbulent flow through the
membrane elements, which would lead to shortened membrane element life.
The pump feeds water to the membrane element housings arranged in parallel and serial
combinations. The direction of water flow is indicated by an arrow on each membrane ele-
ment housing. Water is separated by the membrane elements within the membranes and
leaves the membrane element housings in two streams: permeate and concentrate.
Permeate from each membrane element housing is collected in a common manifold. The
permeate then flows through a flow meter and to the outlet point of the machine.
The concentrate leaves the last membrane element housing and flows to the flow control
center (recycle/concentrate manifold). At this point, the recycle valve channels a prede-
termined amount of concentrate into the pump inlet. Recycle increases recovery while
maintaining adequate cross flow through the membrane elements. The other two ports of
the flow control center lead to the concentrate valve and final pressure gauge. The con-
centrate valve has three functions: It controls the amount of concentrate flowing to the
drain; it controls the pressure within the machine; and it helps control the system recov-
ery. An Autoflush solenoid is added to the flow control center with an additional tee. The
concentrate then flows through a flow meter and to the outlet point of the machine.

Operation of the SEPA-HR membrane element at pressures over 400 psig
(27.6 barg) will reduce salt passage slightly. Operation at 200 psig (13.8
bar) will increase the passage of monovalent ions by approximately 2.0
times and the passage of multivalent ions will increase by 1.5 times the
400 psig (27.6 bar) passage.

multivalent ions tend to have less passage than do monovalent ions. If
monovalent ions are combined with multivalent ions to form a salt, the
passage will be controlled by the multivalent ion. In RO all ions must be
combined as the salt form before passages can be considered.

INSTALLATION
2.1
Mounting
E4H machines are equipped with a stand alone frame, 61-inch (155-cm) H x 132-inch (335
cm) W x 34-inch (86 cm) D, which supports the machine. At least 45 inches
(114 cm) of space should be allowed on each end of the membrane element housings for
removal and loading of membrane elements. If 45-inches (114 cm) are not available, the
entire membrane element housing may need to be removed for membrane element
changes.
2.2
Piping
2.2.1 Inlet Piping
The feed water source is piped to the inlet using 1.5-inch NPT fittings. A CIP
system is supplied with the DLX Model E4H. FOR ECN MODEL: To install a
CIP system, remove plug and install valves on the E-Series machine as described
in Section 2.2.2. If the inlet pressure is in excess of 60 psig (4.1bar) or fluctuates
by more than 5 psig (0.4 bar), a pressure regulator should be installed ahead of the
CIP tee.
2.2.2 Required Valves for Clean-In-Place
NOTE: Clean-In-Place (CIP) valves are only required for Economy (ECN)
Models.
IMPORTANT NOTE: GE Osmonics has installed a plugged pipe tee in the
inlet line of the E4H units. This plug, when removed,
will facilitate cleaning of the unit. A tee with (two)
two-way valves or a single three-way valve should also
be installed on the permeate and concentrate outlets to
allow flow back to the cleaning tank. Never operate
the machine with the concentrate or permeate lines
blocked. Severe damage to the unit may result. (Refer
to the attached drawing # 1163858 for a system flow
schematic.)
2.2.3 Concentrate Outlet Connection
Install the CIP valve on the concentrate outlet tee, connect a 1-inch hose or pipe,
and run it to an open drain. To avoid drainage from the machine while not in use,
the concentrate outlet piping should be placed at a height at least equal to the
height of the machine. A siphon break may also be installed in the concentrate line
for added protection. The concentrate outlet hose can be any length, and the diam-
eter should match the outlet on the machine. [Maximum back pressure is 60 psig
(4.1 barg).]
10
2.2.4 Permeate Outlet Connection
Install the CIP valve on the permeate outlet tee. The pure water (permeate) should
be transported to the point of use via non-corroding-type tubing, pipe, or hose.
Examples are: food-grade flexible nylon tubing, stainless steel tubing, or PVC
hose. The permeate outlet is 1-inch FNPT.
2.3
Electrical
The DLX and ECN E-Series models are supplied with a single-phase, 110 VAC 60 Hz or
220 VAC 50 Hz control circuit and 8-foot cord which plugs into a three-prong
grounded receptacle. For 220 VAC, 50 Hz units, plug must be customer-supplied. A
20 amp dedicated service circuit is required for proper operation.
For each model, the motor is wired at the factory to an overload protection magnetic motor
starter which is controlled by a panel-mounted manual switch.
The electrical system control circuit is separate from the motor voltage. Therefore,
electrical wiring required in the field needs two supply voltages, the control circuit
voltage and a separate three-phase motor voltage. All field wiring must comply with
applicable local and national electric codes.
2.3.1 Economy Electrical System
STEPS
1.
2.
Connect the control circuit power cord to 115 VAC, 60 Hz, or 220 VAC,
50 Hz, single-phase power.
Connect the magnetic motor starter 230/460 VAC or 220/380 VAC,
three-phase power to match the motor voltage and phase. Check the tag
(located on the motor starter) that indicates the factory wiring. A separate,
fused disconnect for the motor wiring is required, with proper protection
for the Hp and amp draw of the motor.
Refer to drawing #1164309 for the ECN electrical diagram. The ECN
circuit has a timing relay for delayed machine shutdown.

PREPARATION AND START-UP
3.1
Pretreatment for Water Purification
All systems will operate most efficiently on filtered water with a pH of less than 6.5 and a
Silt Density Index (SDI) of 5 or below. If the machine is operated on higher pH water,
other forms of pretreatment may be necessary. A water analysis prior to start-up of the
machine is required. To minimize the chances of calcium carbonate, calcium sulfate, or
other salt precipitation on the membrane, GE Osmonics evaluates each application and
water condition and makes specific recommendations to ensure continuity of the mem-
brane membrane element warranty. Data from the water analysis is processed with a com-
puter program analysis to determine if potential problems exist. If the machine is to be run
at a different location than was originally intended, a new water analysis is required for
warranty consideration and should be sent to GE Osmonics for review and recommenda-
tions for operation of the machine.
Before entering the machine, the feed water must be filtered to 5 microns.
Thin-layer composite (TLC) membrane element feed water must not contain the following
chemicals or permanent loss of rejection and/or permeate flow may result:
•
•
free chlorine
formalin (until after a membrane elements have been run for 24 hours; thereafter,
0.5% formaldehyde may be used as a biocide)
•
•
•
•
•
iodine compounds
quaternary germicides
cationic surfactants
detergents containing non-ionic surfactants
cleaners not approved by GE Osmonics
CAUTION: A water softener should not regenerate while the machine is running
unless safeguards are used to be sure the machine is operated on softened
water during regeneration.
3.2
Start-Up
NOTE: If your machine is provided with the membrane elements installed in the hous-
ings, proceed to 3.2.1. If your machine is provided with the membrane elements
in shipping boxes, you must load the membrane elements in the housings prior
to starting the machine. For membrane element loading instructions, skip to
Section 4.6 (Membrane Element Installation). Upon completion of membrane
element installation, return to Step 1 to continue your start-up procedure.
12
STEPS
1.
Re-check the function and integrity of your pretreatment equipment.
Ensure that your water softener, activated carbon filters and iron filters
(where applicable) have been leak-checked, backwashed, and thoroughly
rinsed for service before starting up your RO unit.
2.
3.
4.
Attach the feed water pipe to the inlet of the machine.
Check for leaks at all connection points.
Turn ON the feed water gradually and check for leaks in the inlet piping.
No flow should go through the machine while the power is OFF and the
inlet solenoid is in the closed position.
NOTE: When the machine is OFF, there should never be flow through
the machine. Flow through the machine when it is OFF can ruin
the membrane elements, and the inlet solenoid must be repaired.
5.
6.
Attach tubing from permeate and concentrate outlet points and run the
tubing to drain.
Ensure that you have made provisions for both voltages required to oper-
ate your machine. The machine requires two power sources: (1) the high
voltage for the motor operation, and (2) the control circuit power supply.
The factory provides the 110 VAC (or 220 VAC 50 Hz) power cord need-
ed for the control circuit. The motor electrical service must be field-wired
directly into the motor starter on the machine. Bring your motor service to
terminals labeled “T” on the motor starter. Check the voltage label to
ensure that you have brought the correct voltage to the starter.
7.
8.
Be sure the power to the motor starter is de-energized.
With the machine ON/OFF switch in the OFF position, plug in the facto-
ry supplied 110 VAC (or 220 VAC 50 Hz) power cord.
9.
Open your concentrate and recycle flow control valves two complete
turns. These valves are positioned on the flow control center of the
machine. This piping is located on the left section of the machine, near
the membrane element housings. The flow control center features a con-
centrate flow control valve, a recycle flow control valve, and a pressure
gauge sensor point piped into the panel-mounted pressure gauge.
NOTE: The Autoflush valve is positioned in this flow control center.
The proper adjustment of these valves is critical to the operation of the RO
machine. The concentrate valve determines the amount of rejected water
leaving the machine, and creates the operating pressure shown on the
pressure gauge. The recycle valve returns unused reject flow back into the
13
inlet stream to the RO pump. It is important to balance the operating pres-
sure and the respective flows of these valves to ensure that your machine
is operating correctly. It is also important to understand the relationship of
these two valves, the pressure gauge, and your RO pump. The pump has
a fixed amount of flow produced, and the valves are the control devices to
distribute this fixed flow amount. The pressure gauge is an indicator of
applied membrane element pressure, at the flows set by the valves.
10.
Turn the ON/OFF switch to the ON position. Water will begin to flow
through the machine at this point but the pump will not start. Allow the
machine to operate in this manner for 10 minutes, to purge the air out of
the machine. Verify alarm set points in the Lakewood 2450 Reverse
Osmosis controller.
Consult the Lakewood Model 2450 Installation and Operation Manual
(P/N 1109695) for operating instructions. The factory alarm set points are
as follows:
Low Inlet Pressure
Low pH
12 psig (0.83 barg)
2.0
High pH
8.0
pH Control
High Temperature
5.6 - 6.2
120°F (49°C)
NOTE: The high-pressure pump should not be operating at this time.
As your machine is filling check for leaks and repair as needed.
Turn the ON/OFF switch to the OFF position.
11.
12.
13.
Energize the power source to the motor starter. The pump should not oper-
ate at this point.
14.
Check the rotation of the high-pressure pump by briefly turning the
ON/OFF switch to the ON position. Watch the motor, or coupling shaft,
for direction of rotation. The motor should rotate clockwise as one looks
at the motor end of the high-pressure pump. If the motor is not rotating
clockwise, change any two of the three leads (for three-phase) in the
motor starter and recheck rotation. Always turn the power off to change
any wiring.
WARNING: OPERATION OF THE PUMP BACKWARDS, EVEN
FOR A SHORT TIME, CAN CAUSE DAMAGE TO
THE PUMP.
15.
Turn the ON/OFF switch to the ON position. The high-pressure pump will
operate and the machine will begin to build pressure. As you are operat-
ing, be sure to watch the pressure gauge on the instrument panel. The
machine is designed to operate at 220 psi (15.2 bar).
14
NOTE: Do not allow the pressure to exceed 250 psi (17.2 bar). If the
pressure exceeds 250 psi (17.2 bar), open the concentrate flow
control valve until the pressure gauge shows 250 psi (17.2 bar)
or less.
As the machine purges the air and fills with water, the pressure will grad-
ually increase. You should see water flowing through the permeate and
concentrate flow meters. If you do not see flow, turn the machine OFF and
return to Step 1.
WARNING: NEVER ALLOW THE MACHINE TO OPERATE
WITHOUT ADEQUATE WATER PRESSURE. THIS
CAN CAUSE SEVERE DAMAGE TO THE HIGH-
PRESSURE PUMP
.
16.
Gradually close the concentrate flow control valve. As you close the
valve, watch the pressure gauge and your concentrate flow meter. Close
the valve until your concentrate flow meter displays your design flow, and
you do not exceed 250 psi (17.2 bar). If you reach 250 psi (17.2 bar)
before the valve is completely closed, open the recycle flow control valve
one full turn, then continue to close the concentrate flow control valve.
Continue to close the concentrate flow control valve until it is complete-
ly closed and your pressure is below 250 psi (17.2 bar).
The concentrate flow control valve has a drilled orifice to ensure a prede-
termined amount of flow and pressure in the closed position. This orifice
is sized to operate the machine at 75% recovery.
17.
With the concentrate flow control valve fully closed and the pressure
below 250 psi (17.2 bar), gradually close the recycle flow control valve
until the pressure reaches 250 psi (17.2 bar).
Your machine is now operating at the design pressure and flow rates, in a
75% recovery configuration. Your specific needs or conditions may dic-
tate the need to operate the machine at a lower recovery. If you wish to
operate in a recovery configuration lower than 75%, Step 18 (below) will
explain the necessary steps.
18.
Your machine is equipped with flow meters and a pressure gauge that will
assist you in setting alternate flow rates for variable recoveries. If you
wish to operate at a recovery lower than 75% you must ensure that the
flow rates for the permeate and concentrate are at desired levels. Some
minor adjustments in the concentrate and recycle flow control valves may
be necessary.
See Table 3.1 (Machine Recovery) below for specified flow rates for var-
ious machine recoveries. When you have selected your desired flow rate,
gradually adjust the concentrate flow control valve to achieve desired
flow and use the recycle valve to bring the operating pressure up to
250 psi (17.2 bar).
15
Once the desired flow rate is achieved [250 psi (17.2 bar) operating pres-
sure] no further valve adjustment is needed.
The table below shows flow rates at 50%, 66% and 75% recovery for the
E4H models. Use this table in adjusting flow rates.
NOTE: Permeate flow rates are dependent upon temperature and con-
ditions at your site. Contact your dealer if you have any ques-
tions.

The system is now operational.
Before putting the machine into final operation, continue to run the per-
meate and concentrate streams to drain for at least 30 minutes. This is
done to ensure that all of the bactericide has been removed from the mem-
brane elements.
21.
22.
Connect the permeate line to the point of use of the permeate. Check for
leaks and ensure that you have no kinks in hoses, or blockage of any pip-
ing on the permeate and concentrate outlet lines.
Make any necessary final adjustments to flows and pressure according to
Step 18.
NOTE: The membrane elements in your machine are rated for certain
flow rates at 77ºF (25ºC). Maximum flow rates are achieved
when the membrane elements have been completely rinsed and
on-line for at least 24 hours.

23.
A Daily Log Sheet (Section 10.0) which includes general operating con-
ditions (pressures, flows, concentrations, pH, and pretreatment condi-
tions), and routine or special maintenance (flushing or cleaning as need-
ed) must be kept. This Daily Log Sheet will be required by GE Osmonics
if a warranty question arises.
17
4.0
OPERATION AND MAINTENANCE
The operation and maintenance of your GE Osmonics E4H Machine is relatively simple but
requires regular data recording and routine preventative maintenance. We cannot emphasize too
strongly the importance of filling out the daily log sheet during each operating shift. A data sheet
was filled out upon start-up containing pertinent facts on the operation of your machine. These
two records are invaluable in diagnosing the performance of the equipment and must be kept for
reference. If you have questions concerning the operation of your machine or the method of data
recording, contact the GE Osmonics Application Engineering Department.
The three preventative maintenance procedures which must be done on a regular basis are as fol-
lows:
1.
2.
3.
Change the pre-filter cartridge.
Flush the machine daily.
Clean the machine with approved GE Osmonics cleaners.
See the following sections for specific maintenance procedures.
4.1
Daily Log Sheets
A Daily Log Sheet (Section 10.0) which includes general operating conditions (pressures,
flows and concentrations) and routine or special maintenance (pre-filter changes, flushing,
cleaning, etc.) must be kept. Copies of the log can be made from the template. A copy of
this log sheet will be required by GE Osmonics if a warranty question arises.
4.2
Pre-Filter Cartridge
A 5-micron pre-filter is factory-installed to protect the membrane elements and valves
from particles which may be in the feed water. The pre-filter uses two 20-inch (50.8-cm)
diameter, 5-micron nominal rated cartridges. To order replacements, contact your
distributor.
The pre-filter cartridges must be replaced, at a minimum, once per week or after every 100
hours of operation, whichever comes first. A pressure drop of 8 psig (0.6 bar) across the
filter or more during operation indicates one or more cartridges need changing. Use only
Osmonics approved filters rated for 5 microns or less. Do not attempt to clean used
filters - install new replacements.
IMPORTANT NOTE: Failure to change the pre-filter according to these requirements
will void the warranty.
18
4.3
Flushing
The machine should be flushed at least daily to remove sediment from membrane element
surfaces. To flush the unit:
STEPS
1.
Open the concentrate valve until the pressure gauge indicates the minimum pres-
sure designated on the nameplate. This increases the flushing action on the mem-
brane element.
NOTE: If pressure will not decrease to designated pressure, or if the concentrate
rate does not increase when the valve is opened, the valve may be
plugged.
2.
3.
Operate the machine at the designated minimum pressure for 10 to 20 minutes.
CAUTION: Do not operate the machine below the designated pressure
without approval from GE Osmonics. Operation below the
stated pressure may be detrimental to the pump.
Close the concentrate valve and ensure that the proper concentrate flow rate is
going to the drain (see the nameplate on the panel).
NOTE: The Autoflush (AUF) system, available in DLX packages, automati-
cally flushes the machine and eliminates the need for frequent manual
flushing.
4.4
Cleaning
Cleaning the E4H-Series machine on a regular basis is vital. Over time, contaminants
build up to form a layer on membrane element surfaces, reducing the permeate flow and
quality. If this build-up is not removed from the membrane element, it may cause perma-
nent chemical damage and reduce membrane element life. A decrease in permeate flow
and/or rejection of salts, or an increased pressure drop across the machine will indicate
when cleaning is required. Cleaning may be required as often as once every week or as
infrequently as every two months, depending upon the local water supply conditions.
GE Osmonics recommends cleaning at least every month to ensure good membrane ele-
ment performance and long membrane element life.
GE Osmonics offers a full line of chemical cleaners for specific cleaning needs. See
Table 4.4 (Dry Chemical Cleaners).

CLEANING PROCEDURE
STEPS
1.
With the RO machine running, open the Clean-In-Place (CIP) permeate valve. After this
valve has been opened, close the permeate service valve. Permeate water will flow into
the CIP tank. Allow the water to run through the CIP tank and the CIP tank drain valve
for a few minutes to ensure the tank is rinsed thoroughly. After a minute or so, close the
CIP tank drain valve. The CIP tank should begin to fill with RO permeate. When the CIP
tank has filled to the indicated full line, turn the ON/OFF switch on the RO machine to the
OFF position.
2.
3.
While the machine is OFF, open the CIP inlet valve. Divert the permeate and concentrate
streams to the cleaning container for recirculation. Ensure that the pre-filter is clean. A
CIP pump (supplied with DLX models only) is recommended to supply feed pressure into
the machine.
To circulate the cleaning solution through the machine with suction, remove the CIP plug.
Use a non-collapsible suction hose or pipe to feed the machine.
NOTE: Do not allow the machine pump to operate without concentrate flow. If pump
prime is lost while cleaning on suction, positive inlet pressure is required to
reprime. No air should be sucked into the inlet line during suction cleaning.
20
4.
Turn the CIP ON/OFF switch to the ON position and recirculate the cleaning solu-
tion through the machine. The cleaning solution should be recycled for approxi-
mately 15 minutes or until the solution temperature reaches 85°F (29°C). If heat
rise occurs too quickly, larger volumes of cleaning solution or the use of a heat
exchanger will slow the temperature rise. Turn the CIP OFF and allow it to soak
for 10 minutes.
TLC MEMBRANE NOTE: It is best to clean at temperatures of
100°F - 110°F (38°C to 43°C), but lower temper-
atures will suffice. Do not allow the cleaning
temperature to exceed 110°F (43°C). Allow the
cleaning solution to recirculate for 10 minutes.
Turn the machine off and allow the membrane
elements to soak in the solution for approximate-
ly 20 minutes.
WARNING: DO NOT LEAVE THE CLEANING STRENGTH SOLU-
TION IN THE MACHINE FOR A PERIOD LONGER THAN
ONE HOUR. THE CLEANING SOLUTION MAY DAM-
AGE THE MEMBRANE ELEMENTS AND/OR THE
MACHINE DURING AN EXTENDED PERIOD OF CON-
TACT.
5.
6.
To flush the detergent from the machine, close the CIP inlet valve and divert the
permeate and concentrate to drain by opening the CIP drain valve. Operate the
machine as described in the flushing section (Section 4.3, Flushing) for at least one
hour. The detergent is sufficiently flushed when the permeate conductivity is
restored to nearly its previous level.
To return the RO to service, open the permeate, concentrate valves so that flow is
routed as intended in the service mode. Close the CIP permeate, CIP concentrate
valves. The RO is now ready for operation.
4.5
Draining Machine for Shipment
Prior to shipping or outside storage of a GE Osmonics E4H Machine, the system should
be cleaned with the appropriate cleaner, flushed with water, and protected from biological
attack with the appropriate solution for TLC membrane. The membrane element housings
and piping lines of the machine must be completely drained. Any water remaining in the
piping of a machine may freeze, causing damage to the piping, pump, membrane elements,
etc. The party shipping or storing the machine is responsible for any damage resulting
from freezing.
STEPS
1.
2.
Disconnect the inlet, concentrate and permeate outlets.
Drain all water from the cartridge filter housing.
21
3.
Remove the tubing connections on the inlets and outlets of the membrane element
housings.
4.
5.
6.
Open the concentrate valve.
Remove the drain plugs from all PVC manifolds.
Be sure the flow meters are drained by disconnecting the bottom fitting of each
flow meter.
7.
8.
Allow the machine to drain for a minimum of eight hours or until the opened ports
quit dripping.
After draining is complete, reconnect all of the piping.
4.6
Membrane Element Installation
NOTE:
For machines with membrane elements not loaded at the factory, the fol-
lowing steps are to be used for installation.
CAUTION: The membrane element is packaged in a small amount of bactericide solu-
tion to prevent biological growth; provide adequate ventilation when han-
dling. The membrane element must be kept moist at all times in order to
prevent possible damage to the membrane element material.
STEPS
1.
Remove the membrane element bag containing the membrane element from the
shipping tube.
2.
3.
4.
Cut the bag open as close as possible to the seal at the end of the bag, so that the
bag may be re-used if necessary.
Remove the membrane element from the bag and remove the foam protectors from
each end of the membrane element.
Remove the parts from the parts container (if included) and inspect. Make sure that
all parts are clean and free from dirt. Examine the O-rings, brine seal, and perme-
ate tube for nicks or cuts. Replace the O-rings or brine seal if damaged. Set the
membrane element aside in a clean space and continue on to Step 5.
5.
6.
Remove the end caps from both ends of all membrane element housings on your
machine. This is done by loosening the clamp bolts at each end cap closure
assembly.
Determine the direction of fluid flow in the membrane element housing. (Be cer-
tain to look at the “Direction of Flow” arrow for each membrane element housing.
Direction of flow may vary within a given machine.)
22
7.
8.
9.
Inspect the membrane element housing and clean as necessary to remove any con-
taminants, obstructions, etc.
Apply a small amount of O-ring lubricant to all O-rings on the end caps, and the
brine seal on the membrane element.
Insert the downstream end of the membrane element in the upstream end of the
membrane element housing (i.e., load in the direction of flow; the brine seal is on
the end of the membrane element that goes in last. For membrane element hous-
ings with the flow arrow pointing up refer to Step 10.
10.
11.
12.
Insert the membrane element in the membrane element housing with a smooth and
constant motion. When you reach the point where the brine seal is about to enter
the housing, gently turn the membrane element to ensure the brine seal enters the
housing without coming out of the brine seal groove.
When all of your membrane elements are installed, you must close the membrane
element housing by reinstalling the end caps and clamps. It is preferred to install
the bottom end cap first, and tighten the clamp completely, before installing the
top end cap.
Reinstall the end caps by gently twisting the end cap while pushing it on to the
permeate tube. Ensure that you do not pinch or fatigue any O-rings while pushing
the end cap on. Push the end cap on until the outer diameter of the cap is flush with
the outer diameter of the membrane element housing. Install the clamp halves, and
tighten the bolts until the clamp halves meet.
13.
14.
Reconnect any fittings that were removed when disassembling the membrane ele-
ment housings.
Return to Section 3.2 (Start-Up, Step 1).
4.7
Membrane Element Replacement
As time progresses, the efficiency of the membrane element will be reduced. In general,
the salt rejection does not change much until two-three years after installation, when oper-
ated on properly pretreated feed water and when routine maintenance is performed. The
permeate flow rate will begin to decline slightly after one year of operation but can be
extended with diligent flushing and cleaning of the machine. High pH feed water and/or
precipitation of hardness can cause premature loss in rejection and even flow rate. The fol-
lowing procedure is to be followed to replace existing membrane elements in the machine.
STEPS
1.
Remove the end caps and clamps from all of the membrane element housings.
23
2.
3.
Remove all the membrane elements from the membrane element housings in the
direction of flow, where possible. If necessary, a membrane element can be
removed against the direction of flow. A heavy duty pliers or channel lock pliers
may be necessary to pull the old membrane element our of the membrane element
housing.
To reinstall replacement membrane elements, follow Steps 4 -14 (Section 4.6,
Membrane Element Installation).
NOTE: Do not operate the machine on water over 85°F (29°C).
NOTE: Do not allow the machine to freeze unless it is totally drained. The
machine must thaw a minimum of 24 hours before starting.

OPTIONAL ACCESSORIES
5.1
Level Controls
Float switches, pressurized storage switches or other level controls should be wired into
the control circuit line prior to the switch on the unit. The following ensures that the inlet
valve, instruments, and pump are not powered when storage tanks are full: float switch
assembly with cord, counterweight, and plastic float (used with an atmospheric storage
tank).
5.2
5.3
Filters and Water Softeners
Backwashable filters and softeners should be installed such that unfiltered or unsoftened
water will not be fed to the machine while the RO unit is operating. Failure to do this may
cause fouling or precipitation of calcium carbonate or other materials onto the membrane
elements.
Storage Tanks
Fiberglass, polyethylene, and stainless steel storage tanks are available. All tanks are
available with fittings installed at the factory. These tanks must be installed with even sup-
port along the bottom.

Warranty Service
SELLER’S OBLIGATION UNDER THIS WARRANTY IS LIMITED TO REPAIR OR
REPLACEMENT (AT SELLER’S SOLE OPTION) OF ANY PRODUCT, OR COMPO-
NENT THEREOF, PROVED TO BE DEFECTIVE IN MATERIAL OR WORKMAN-
SHIP WITHIN THE COVERED WARRANTY PERIOD. The Buyer. at the Buyer’s risk
and expense, shall be responsible for returning such product or component, upon obtain-
ing a Return Goods Authorization (RGA) number from the Seller, freight prepaid, and in
conformance with any special packaging and shipping instructions set forth on the opera-
tion documentation or RGA instructions, or as otherwise reasonably required, to the
Seller’s address set forth below, together with (1) RGA number issued by Seller at Buyer’s
request; (2) proof of purchase and, if necessary, proof of installation date; (3) a description
of the suspected defects; (4) the serial number of the Seller product alleged to be defec-
tive; and (5) a description of the type of water pretreatment equipment which has been uti-
lized in connection with the product, if any. Seller shall, in Seller’s reasonable discretion,
be the sole judge of whether a returned product or component is defective in material or
32
workmanship. Required or replaced products or components shall be returned to the
Buyer by the Seller, freight prepaid by Seller, via UPS ground or best way surface freight.
In genuine emergency situation, Seller will (at Seller’s sole option) forward replacement
parts to Buyer without waiting for authorized return of the questionable part(s). In such
cases, Buyer will issue a purchase order or other payment guarantee prior to shipment. If
the returned part is found to have been misused or abused, the defective part is not received
by Seller within thirty (30) days, the Buyer will be invoiced for replacement part(s) pro-
vided. This Warranty does not cover or include labor and/or travel to the Buyer’s premise
or location or any other location. Charges will be made for the usual and customary Seller
costs and associated expenses incurred by Seller in providing Warranty Service at any
location other than Seller’s factory at the address set forth below, and Seller reserves the
right to precondition such travel to Buyer’s premises upon prepayment of Seller’s antici-
pated costs of attending such premises.
Voidability of Warranty
This Warranty shall be void and unenforceable as to any Seller product which has been
damaged by accident, mishandling, abuse or has been repaired, modified, altered, disas-
sembled or otherwise tampered with by anyone other than Seller or an authorized Seller
service representative; or, if any replacement parts are not authorized by Seller have been
used, or, the product has not been installed, operated and maintained in strict accordance
and adherence with the operating documentation and manuals for such product. Any
express warranty, or similar representation of performance set forth in the operation doc-
umentation for a reverse osmosis or ultrafiltration membrane incorporated into a Seller
product shall be void and unenforceable unless the feed water requirements set forth in the
operating documentation for such product are unequivocally and strictly adhered to.

ARE EXCLUSIVE AND IN LIEU OF ANY AND ALL OTHER WARRANTY OR
REMEDIES, EXPRESSED OR IMPLIED, INCLUDING WITHOUT LIMITATION,

FOR DAMAGES FOR THE LOSS OF PRODUCTION OR PROFITS, OR INJURY TO
PERSON OR PROPERTY. NO PERSON HAS ANY AUTHORITY TO BIND SELLER
TO OTHER THAN WHAT IS SET FORTH ABOVE.

BUYER MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM JURISDICTION
TO JURISDICTION. THE PARTIES RECOGNIZE AND AGREE, THAT IN ALL
RESPECTS THE LAWS OF THE STATE OF MINNESOTA SHALL APPLY TO AND
