1.0DESCRIPTION

E-CE Series Reverse Osmosis (RO) machines are durable pieces of equipment, which, with prop- er care, will last for many years. These instructions give operation and maintenance details vital to the sustained performance of the machine. Please read completely before operating your machine.

1.1Definitions

The operating definitions provided below will help you further understand your machine and this manual.

1.1.1Permeate Rate (Product Water Rate) [Qp]

The Permeate Rate is the flow rate of purified water that passed through the mem- brane element and out of the membrane element in liter/min (Lpm), cubic meters/hour (m3/h), gallons/min (gpm) or gallons/hour (gph). Specified perme- ate rates are based on a feed water temperature of 25??C (77??F). Permeate rate will vary with temperature.

1.1.2Concentrate Rate (Wastewater Rate) [Qc]

The Concentrate Rate is the flow of incoming water in Lpm or m3/h (gpm or gph).

1.1.3Feed Rate [Qf]

The Feed Rate is the flow rate of incoming water in Lpm or m3/h (gpm or gph). Feed water rate equals permeate plus concentrate rate.

1.1.4Reverse Osmosis

Reverse Osmosis (RO) is the separation of one component in a solution from another component of a solution from another component by means of pressures exerted on a semi-permeable membrane element. The feed solution is separated into two streams, permeate and concentrate, and collected from both sides of the membrane element.

Normal Versus Cross Flow Filtration

1.1.5Membrane Elements

Membrane elements are interleaved layers of semi-permeable membrane, spacer, and permeate carrier spiraled around a central permeate tube make up the mem- brane element.

Figure 1.2

Membrane Element with Interconnectors

1.1.6Clean-In-Place

The abbreviation for Clean-In-Place is CIP.

1.1.7Flow Control Center

The Flow Control Center features a concentrate flow control valve, a recycle flow control valve, and a pressure gauge. It is located directly behind the control enclo- sure.

1.1.8Average Pressure

PAVG (Average Pressure) = [(PPRIMARY + PFINAL) ??? 2]

1.1.9Concentration

Concentration equals the Total Dissolved Solids (TDS) concentration of a solution expressed as conductivity (???S/cm) or parts per million (ppm).

1.1.10Salt (Ionic) Passage

Ionic Salt Passage equals the percent of dissolved salts passed through the mem- brane element or 100% minus rejection.

1.1.11Recovery

Recovery equals permeate rate divided by feed rate and is expressed as a per- centage. For example, 75% recovery means that out of a given feed rate, 75% is produced as purified water (permeate).

1.1.12Salt (Ionic) Rejection

Ionic Salt Rejection equals the percent of dissolved salt rejected by the membrane element, calculated from an average concentration over the membrane element.

An example of how to calculate salt rejection and recovery is below:

2.0INSTALLATION

The following installation guidelines will help you install your new E-CE RO machine.

2.1Feed Water Requirements

The following feed water requirements must be met before installing your new E-CE RO machine to ensure quality permeate and extended membrane element life.

Table 2.4

Feed Water Requirements

2.2Mounting

E-CE Series machines are equipped with a stand-alone frame, which supports the machine. At least 114 cm (45-inches) of space should be allowed on each end of the

membrane element housings for removal and loading of membrane elements. If 114 cm (45-inches) are not available, the entire membrane element housing may need to be removed for membrane element replacement.

2.3Plumbing

The E4H-CE and E8-CE come with flanged connections installed on all isolation valves.

Table 2.5

Connections

2.4Power and Electrical Requirements

WARNING: BEFORE OBTAINING ACCESS TO TERMINALS, ALL SUPPLY

CIRCUITS MUST BE DISCONNECTED.

IMPORTANT NOTE: Motor are dual rated. Factory installed starters and wiring are for 400VAC (380VAC). Motor starter and motor wiring must be replaced prior to converting to lower voltage. Custom Factory Order (CFO) based motors can be rated at other voltages. Check motor for rating.

The E4H-CE and E8-CE machines are supplied with a single source of incoming power. This power can be 230, 380, 415, 460, or 575 VAC. Check tag on High Voltage Enclosure to verify which voltage is required. The power for control is transformed down from the three-phase power at the main disconnect to 230 single-phase and then down to 24 VDC.

For each model, the motor is wired at the factory to an overload protection motor starter, which is controlled by the panel-mounted Operator Interface Terminal (OIT).

3.0PREPARATION AND START-UP

3.1Pretreatment 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 element, GE Osmonics evaluates each applica- tion and water condition and makes specific recommendations to assure continuity of the membrane element warranty. Data from the water analysis is processed with a computer program analysis to determine if potential problems may exist. If the machine is to be run at a different location than was originally intended, a new water analysis is required for warranty considerations and should be sent to GE Osmonics for review and recommen- dations for operation of the machine.

Before installing the machine, the feed water must be filtered to 5 microns.

Thin-layer composite (TLC) membrane element feed water must not contain the follow- ing chemicals or permanent loss of rejection and/or permeate flow may result:

Free chlorine

Formalin (until after membrane element has run for 24 hours, thereafter, 0.5% formalde- hyde 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.

NOTE: To control the RO operation based on water softener regeneration cycle, wire the softener to the Pretreatment Shutdown Control circuit, as described in Field Installed Accessories.

3.2Initial Start-Up

NOTE: If your machine has the membrane elements installed in the housing, pro- ceed to Steps below. If your machine is provided with the membrane ele- ments in shipping boxes, you must load the membrane elements in the housings prior to starting the machine. For membrane element loading instructions, go to Section 4.5 (Membrane Element Installation). Once membrane element installation is complete, return to Step 1 (below) to continue the start-up procedure.

STEPS

1.Recheck the function and integrity of your pretreatment equipment. Ensure that your water softener, activated carbon filters, and iron filters (where applicable) have been leaked checked, back washed, and thoroughly rinsed for service before starting up your RO unit.

2.Attach the feed water pipe to the inlet of the machine. The standard connection fitting is a polyvinyl chloride (PVC) flanged connection. Refer to Table 2.5 (Connections) for connection sizes.

3.Check for leaks at all connection points.

4.Turn the feed water supply gradually ON and check for leaks in the inlet plumb- ing.

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 mem- brane elements.

5.Attach discharge plumbing to permeate and concentrate outlet points and run the tubing to the drain. The standard connection fitting is a polyvinyl chloride (PVC) flanged connection. Refer to Table 2.5 (Connections).

6.The machine requires one high voltage power source. The motor electrical ser- vice must be field wired directly into the motor starter on the machine. Be sure the power to the motor starter is de-energized by turning the disconnect on the high voltage enclosure to the OFF position. The high voltage enclosure can only be opened while in the OFF position. Bring your motor service to terminals labeled ???T??? on the motor starter. Check the voltage label to ensure you have brought the correct voltage to the starter.

IMPORTANT NOTE Motors are dual rated. Factory installed starters and wiring are rated for 400VAC (380VAC). The motor starter and motor wiring must be replaced prior to con- verting to a lower voltage.

7.Open your concentrate and recycle flow control valves (located behind the con- trol enclosure).

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 inlet stream to the RO pump. It is important to balance the operating pressure 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 pres- sure gauge is an indicator of applied membrane element pressure a the flows set by the valves

8.Press the Fill Button on the OIT so it is in the ON position. Water should begin to flow through the machine at this point, but the pump will not start. Allow the machine to fill for ten (10) minutes.

9.As your machine is filling check for leaks and repair as needed.

10.Turn the ON/OFF switch, located on the High Voltage Enclosure, to the ON posi- tion.

11.Energize the power source to the motor starter. The pump should not operate at this point.

12.Check the rotation of the high-pressure pump:

12a Press the RO button so it is in the ON position.

After the minimum inlet pressure [0.8 bar (11.6 psi)] is established and maintained for six (6) seconds, the high-pressure pump will start.

12b When the high-pressure pump starts, immediately press the RO button so it is in the OFF position.

The motor should rotate clockwise while looking at the motor end of the high- pressure pump. If the motor is not rotating clockwise, change any two of the three leads in the motor starter and recheck rotation.

WARNING: ALWAYS TURN POWER OFF TO CHANGE ANY

WIRING.

CAUTION: Operation of the pump backward, even for a short time, can cause damage to the pump.

13.Press the RO button so it is in the ON position. The high-pressure pump will operate and the machine will begin to build pressure.

14.As the machine is operating, watch the primary and final pressure gauges on the instrument panel. The machine is designed to operate at approximately 7.6 bar (110 psi).

NOTE: Do not allow the pressure to exceed the maximum boost pressure (Pmax) specified for your machine model (Table 1.2). If the pressure exceeds Pmax, open the concentrate and/or recycle control valves until the pressure gauge shows Pmax or less.

15.As the machine purges the air and fills with water, the pressure will gradually increase. Water should flow through the permeate and concentrate piping, viewed on the individual flow meters. If you do not see flow, turn the machine OFF and return to Section 3.2 (Initial Start-Up).

16.Gradually adjust the concentrate flow control valve. As you adjust the valve, watch the average pressure (Pavg) and the your concentrate flow meter. Adjust the valve until your concentrate flow meter displays the desired flow and does not exceed Pmax. If Pmax is exceeded before the valve is completely closed, open the recycle flow control valve one full turn, then continue to adjust the concentrate flow valve.

17.With the concentrate flow control valve set to obtain the desired concentrate flow and the pressure below Pmax, gradually adjust the recycle flow control valve until Pavg reaches 7.6 bar (110 psi). Readjust the concentrate and then the recycle valves, if necessary.

18.Once the desired flow rate is achieved [7.6 bar (110 psi)] operating pressure, no further valve adjustment is needed.

NOTE: Permeate flow rates are dependent upon temperature and conditions at your site. Contact your distributor if you have any questions.

The system is now operational.

19.Before putting the machine into final operation, continue to run the permeate and concentrate streams to the drain for at least thirty (30) minutes. This is done to ensure that all the preservative have been removed from the membrane elements.

20.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 plumbing on the permeate and concentrate outlet lines.

21.Make any final adjustments for flow and pressure, according to Step 18, if need- ed.

22.Complete and create copies of the Start-Up Log Sheet (Section 7.2). A Daily Log Sheet (Section 7.3), including general operating conditions (pressures, flow, con- centrations, pH, and pretreatment conditions) and routine or special maintenance (flushing or cleaning as needed) must be kept. GE Osmonics will require these Log Sheets if a warranty question arises.

4.0MACHINE OPERATION AND MAINTENANCE

The operation and maintenance of a E-CE RO Series machine is relatively simple, but requires regular data recording and routine preventative maintenance. It cannot be emphasized enough the importance of filling out the Daily Log Sheet (Section 7.3) during each operating shift. A Start- Up Data Sheet was completed at start-up (Section 7.2) containing pertinent facts on the operation of your machine. These two records are invaluable in diagnosing the performance of the equip- ment or warranty issues, 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.

Three preventative maintenance procedures, which must be done on a regular basis, are as follows:

1.Change the pre-filter cartridges.

2.Flush the machine.

3.Clean the machine with approved Osmonics cleaners.

4.1Daily Log Sheets

A Daily Log Sheet, 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 Daily Log Sheet can be made from the Template (Section 7.3). GE Osmonics will require copies of Daily Log Sheets if a warranty ques- tion arises.

4.2Pre-filter Cartridge

A 5 micron pre-filter cartridge is factory installed to protect the membrane elements and valves from particles, which may be in the feed water. To order replacements, see the Spare Parts List (P/N 1233377).

Pre-filter cartridge must be replaced, at a minimum, once per week or after every 100 hours of operation, whichever occurs first. A pressure drop across the filter of 0.6 barg (8.7 psig) or more during operation indicates that the pre-filters cartridge(s) need chang- ing. Use only GE 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 filter according to these requirements will void machine warranty.

4.3Cleaning

Cleaning the E-CE RO machines 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 per- manent 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 indi- cate when cleaning is required. GE Osmonics recommends cleaning at least every month to assure good membrane element performance and long membrane element life.

GE Osmonics offers a full line of chemical cleaners for specific cleaning needs. Refer to the Spare Parts List (P/N 1233377).

To clean membrane elements:

STEPS

1.The E-CE RO machines do not include a Clean-In-Place (CIP) pump. A CIP pump and tank need to be installed in order to complete the cleaning process. GE Osmonics offers a stand-alone CIP system for the cleaning process. Refer to the Spare Parts List (P/N 1233377).

2.With the E-CE RO machine running, open the CIP permeate valve. After this valve has been opened, close the permeate service valve. Permeate water will flow into the CIP tank. Open the CIP tank drain valve. Allow the water to run through the CIP tank and the CIP drain valve for a few minutes to assure the tank is rinsed thoroughly. Once the tank is rinsed, close the CIP tank drain valve. The CIP tank will begin to fill with RO permeate. When the CIP tank has filled to the indicated full line, press the RO button so it is in the OFF position.

3.With the machine OFF, close the service inlet and concentrate valves and open the CIP inlet and concentrate valves. This will divert permeate and concentrate streams to the cleaning container for recirculation. Insure that the pre-filter is clean. GE Osmonics recommends that you replace the pre-filters prior to clean- ing and again replace pre-filters after cleaning. Call GE Osmonics Customer Support Center with questions concerning pre-filter replacement and cleaning.

4.Press the CIP button so it is in the ON position. The cleaning solution should be recirculated for approximately fifteen (15) minutes or until the solution tempera- ture reaches 38??C (100??F). DO NOT EXCEED 43??C (110??F). The membrane elements can only handle temperatures in excess or 29??C (85??F) for short periods of time. If heat rise occurs to quickly, larger volumes of cleaning solution or the use of a heat exchanger will slow the temperature rise. Press the CIP button so it is in the OFF position and allow the machine to soak for ten (10) minutes.

CAUTION Do not leave the cleaning strength solution in the machine for a period longer than one hour. The cleaning solution may damage the membrane elements and the machine during an extended period of contact.

5.To flush the detergent from the machine, close the CIP inlet valve, open the ser- vice inlet valve, and divert permeate and concentrate to the drain by opening the CIP drain valve. Press the RO ON/OFF button so it is in the ON position to

reestablish normal operation. Operate the machine as described in the flushing section for at least one hour. The detergent is sufficiently flushed when the per- meate conductivity is restored to its normal previous level. When conductivity is back to normal, divert the permeate and concentrate back to service positions.

4.4Draining Machine for Shipment

Prior to shipping or outside storage of a GE Osmonics E-CE RO machine, the system should be cleaned with the appropriate cleaner, flushed with water, and protected from biological attack with the appropriate solution. The membrane element housings and pluming lines of the machine must be completely drained. Any water remaining in the plumbing may freeze, causing damage to the plumbing, pump, membrane elements, etc. The party shipping or storing the machine is responsible for any damage resulting from freezing.

STEPS

1.Disconnect the inlet, concentrate, and permeate outlets.

2.Drain all water from the pre-filter cartridge housing.

3.Remove the tubing connections on the outlets of the membrane element housings.

4.Open the concentrate valve.

5.Open all sample/drain valves.

6.Remove drain plug from pump discharge plumbing.

7.Allow the machine to drain for a minimum of eight (8) hours or until the opened ports quit dripping.

8.After draining is complete, reconnect all of the plumbing.

4.5Membrane Element Replacement

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.

For machines with membrane elements not loaded at the factory:

STEPS

1.Remove the membrane element bag containing the membrane element from the shipping tube.

2.Cut the bag open as close as possible to the seal at the end of the bag, so that the bag may be reused if necessary.

3.Remove the membrane element from the bag and remove the foam protectors from each end of the membrane element.

4.Remove the parts from the parts container (if included) and inspect. Make sure all parts are clean and free of dirt. Examine the O-rings, brine seal, and permeate 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.Remove the end caps from both ends of all membrane element housings on your machine. This is done by removing the screws and retaining ring on each end cap closure assembly.

6.Determine the direction of fluid flow in the membrane element housing. (Be cer- tain to look at the ???Direction of Flow??? arrow on each membrane element housing; they may be different within a given machine.)

7.Inspect the membrane element housing and clean as necessary to remove any con- taminants, obstructions, etc.

8.Apply a small amount of O-ring lubricant to all O-rings on the end caps and the brine seal on the membrane element.

9.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).

10.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 that the brine seal enters the housing without coming out of the brine seal groove.

11.When all of your membrane elements are installed, close the membrane element housing by reinstalling the end caps and clamps. It is preferred to install the bot- tom end cap first and tighten the clamp completely before installing the top end cap.

12.Reinstall the end caps by gently twisting the end cap while pushing it on to the permeate tube. Insure 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 passes the retaining ring groove. Install the retaining ring screws.

13.Reconnect any fittings that were removed when disassembling the membrane ele- ment housings.

14.Return to Initial Start-Up (Section 3.2).

4.6Membrane Element Removal

As time progresses, the efficiency of the membrane element will be reduced. In general, the salt rejection does not change much until two or three years after installation, when operated on properly pretreated feed water and routine maintenance performed. The per- meate 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 following procedure is to be followed to replace existing membrane elements in the machine.

STEPS

1.Remove the end caps and clamps from all the membrane element housings.

2.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. Heavy-duty pliers or channel-lock pliers may be necessary to pull the old membrane element out of the membrane element housing.

3.To reinstall replacement membrane elements, see Section 4.5 (Membrane Element Replacement).

NOTE: Follow Membrane Element Specifications (Table 1.3).

NOTE: Do not allow the machine to freeze unless it is totally drained. It must thaw a minimum of 24 hours before starting.

5.0FIELD INSTALLED ACCESSORIES

5.1Pretreatment Shutdown

E-CE Series RO machines are equipped with Pretreatment Shutdown control capability. Pretreatment Shutdown is the ON/OFF control of the RO via a signal from a remote device. External Control can be used when Permeate Flush is not desired prior to RO shutdown (Permeate Flush, Section 5.2). The Permeate Shutdown control could be remote ON/OFF, level control, pretreatment lockout, and/or post-treatment lockout, etc. Utilization of this feature requires a customer-wired control loop, wired to factory-sup- plied terminals. This procedure is as follows:

WARNING: BEFORE OBTAININGACCESS TO THE TERMINALS, ALL SUP-

PLY CIRCUITS MUST BE DISCONNECTED.

STEPS

1.Establish that the remote device(s) have dry contacts available to provide the shut- down signal to the RO. Ensure that the normal mode of contact is such that it opens when shutdown is desired.

2.With power removed from control enclosure, open enclosure.

3.Wire from the 24VDC source terminal #514 to the first remote device. Wire all additional devices in series with the first. Wire the last remote device to terminal #1006.

4.On the OIT, press the ???Auto/Hand??? button located under the RO button. Make sure it is in the Auto position.

With multiple remote devices wired in series, as described above, an open contact from any of the configured devices will activate the External Control Shutdown.

5.2Permeate Flush

Permeate Flush is designed into the E-CE-RO machines to provide an integral means of reducing the fouling potential of the stagnant concentrate in the RO during extended peri- ods after automatic shutdown. The E-CE-RO machines are equipped with the necessary plumbing and electrical controls to provide a 10-minute pure water (permeate) flush. Activation of the purge cycle by remote device requires a customer-wired control loop to factory supplied terminals. This procedure is provided later.

A second way to perform permeate purge is by manually pressing the Permeate Purge but- ton on the OIT screen.

The purge cycle is activated by a shutdown signal received from an external device wired to the RO. Upon activation of the Purge Cycle, the machine remains in run mode and the permeate stream is redirected to the inlet of the machine. The feed water is diluted by an amount proportional to the operating recovery of the machine. The net result, after con-

centration of the diluted feed stream, at the operating recovery, is that the water in the machine at shutdown will have total dissolved solids (TDS) concentrations approximate- ly equal to the machine feed TDS level. The low TDS environment created reduces the potential for membrane element fouling during the down period, extending membrane ele- ment life. The purge operates for a ten (10) minute period. During this period, no per- meate is discharged from the machine and concentrate flows from the machine at the nor- mal operating rate. When the cycle is complete, the RO pump will shut down. When the request to restart is received, the RO will restart and operate as normal. If the restart sig- nal is received during the Purge Cycle, the cycle will terminate and the RO will return to normal operating mode.

Since this feature is designed to provide a low TDS environment during extended shut- down periods, the purge sequence will not activate for any factory-configured shutdown event (i.e., ON/OFF switch, alarm shutdown, etc.). These shutdown events are assumed to be typically short down periods. Also, activation of the purge cycle for these events may be undesirable if immediate shutdown is required. The purge cycle will activate when a shutdown request is made by an external component that is configured for purge- activated RO shutdown.

Level control of a permeate storage tank is GE Osmonics??? standard external control device which activates the purge shutdown. Any other remote device(s) can be used where per- meate purge is desired prior to RO shutdown. Examples include: remote ON/OFF, post- treatment lockout, etc.

WARNING: DO NOT CONFIGURE PRETREATMENT DEVICES FOR

PURGE-ACTIVATED SHUTDOWN. THE PURGE CYCLE

REQUIRES THE FEED WATER SUPPLIED BY THESE

DEVICES.

To establish the control loop for purge-activated shutdown, perform the following steps:

WARNING: BEFORE OBTAINING ACCESS TO TERMINALS, ALL SUPPLY

CIRCUITS MUST BE DISCONNECTED.

STEPS

1.Establish that the remote device(s) has dry contacts available to provide the shut- down signal to the RO.

2.With power removed from the control enclosure, open enclosure.

3.Wire from the 24VDC source terminal #515 to the first remote device. Wire all additional devices in series with the first. Wire from the last remote device to ter- minal #1007.

4.Turn the AUTO/HAND Button on the Purge Button located on the OIT to the ???AUTO??? position.

With multiple remote devices wired in series, as described above, an open contact from any of the configured devices will activate the Permeate Purge Cycle.

5.3Chemical Pump

GE Osmonics offers a stand-alone chemical pump and tank that can be used to control the pH of the RO system. Refer to the Spare Parts List (P/N 1233377) for ordering informa- tion.

5.4Clean-In-Place Installation

8.0WARRANTY

8.1Warranty Terms

Subject to the terms and conditions set forth hereinafter, Seller (GE Osmonics, Inc. or any of its authorized subsidiaries) warrants to the original purchaser (hereafter the ???Buyer???) that the products manufactured by Seller are free from defects in material and in work- manship for twelve (12) months from the Warranty Commencement Date (as defined below) only when used strictly in accordance with the applicable operating instructions and within the range of the operating conditions specified by Seller for each such product. This Warranty does not extent to equipment or components manufactured by others into which a Seller product has been incorporated or to equipment or components which have been incorporated into a Seller product but, if allowable, Seller hereby assigns, without warranty, to the Buyer its interest, if any, under any warranty made by the manufacturer of such equipment or component. This Warranty does not cover disposable items such as fuses, lamps, filters, cartridges, or other such disposable items, which must be replaced periodically under the normal and foreseeable operating conditions of the goods warrant- ed hereby.

8.2Warranty Commencement Date

The Warranty Commencement Date for each Seller product shall be the later of the date of: (1) receipt by the Buyer, or (2) the date of installation at the Buyer???s premises provid- ed that such installation must occur within three (3) months of shipment from the Seller???s manufacturing facility in Minnetonka, Minnesota. In no event shall the Warranty Commencement Date exceed three (3) months from the shipment from the Seller???s man- ufacturing facility. The Buyer shall provide proof of purchase in order to exercise rights granted under this Warranty. If requested by Osmonics, the Buyer must also provide proof of the installation date. Proof of installation shall be returned by Buyer to Seller within thirty (30) days after installation by virtue of supplying a Warranty Validation Card sup- plied with each Seller product fully completed and signed in ink by Buyer and the autho- rized installer of the product.

8.3Warranty 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 descrip- tion of the suspected defects; (4) the serial number of the Seller product alleged to be defective; and (5) a description of the type of water pretreatment equipment which has been utilized 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 workmanship. Required or replaced products or components shall be returned 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) provided. This Warranty does not cover or include labor and/or trav- el 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 pre- payment of Seller???s anticipated costs of attending such premises.

8.4Voidability 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.
