With proper care, preventative maintenance, and proper use, it should provide you with a very effective means of treating water for dialysis treatments. Before starting you should first read and have a thorough understanding of this entire Operator Manual. It describes in detail the steps and procedures for safe usage of the Matrix RO. Once the device has been delivered to you, "it is the responsibility of the Medical Director to ensure that the [device] is operated, monitored, and maintained in such a manner so as to satisfy all applicable standards for which the water may be used". (Quoted from HHS Publication FDA 89-4234). The RO cannot do the job alone. It is important to understand and monitor the changing tap water conditions, which include contaminants, temperature, pH, pressure and flow-rates, which have a direct impact on the quality and quantity of the RO’s output. This RO was designed to your specifications and requirements. Since municipal water conditions are constantly changing, good two-way communications with your municipal water supplier coupled with routine testing of the tap water is vital to the safe and effective operation of this device. To emphasize the importance of water treatment and proper use of water treatment equipment used for hemodialysis, the following is quoted from HHS Publication FDA 89-4234, "Numerous reports have documented that use of inadequately treated water for hemodialysis poses a severe threat to the health and safety of the hemodialysis patient. Despite this, water treatment and water quality are often neglected areas of hemodialysis. A major reason for this neglect is that water treatment is a technically complex subject which is not generally a part of the education and training of clinical staff in hemodialysis facilities."

MONITOR and CONTROL SYSTEM The Matrix RO is a semi-automated system comprised of several components that provide monitoring and control capabilities. The system operation is controlled by a Programmable Logical Controller (PLC). An Operator Interface Terminal (OIT) allows the user to select and monitor unit operation, review logs and trends, or view system parameters. It processes the analog and digital inputs and generates output signals to operate the unit. The PLC supplies the data to be displayed on the OIT. The Control Box houses both the PLC and the OIT as well as a 24 VDC Power Supply. This power supply provides power to the PLC, OIT, and to some solenoids and solenoid valves. There is a Power Switch inside the control box which is used to turn the PLC and OIT on or off, which should remain in the “ON” position during normal operation. A keyed OPER-DISINFECT Switch is an additional safety feature to prevent unauthorized activation of the disinfect cycle. In addition to visual alerts displayed on the OIT, the control box also has a visual RO Alarm Light as well as an Audible Alarm to alert users when required. During an alarm condition, the RO Alarm Light will remain on until the alarm conditions are cleared and the alarms are reset by pressing the RESET button on the OIT. The system also has a remote alarm which is usually installed near an operator or nurses’ station. A Feed Water Low Pressure Switch is located on the post-inlet filter. This switch, in conjunction with the PLC, will shut down the pump in the event of insufficient fluid flow through the pump to prevent pump failure. There are also two Conductivity Probes (Feed & Product), which work in concert to measure TDS as a function of conductivity. If the alarm is caused by poor water quality during the first 3 minutes, the RO alarm light will be lit, and neither the audible alarm or remote alarm will sound. Once the water quality meets the requirements this alarm light will go out. If after 3 minutes, if still in a poor water condition, the alarm light will be lit, and both the audible alarm and remote alarm will sound. RO UNIT The RO unit is built on a stainless-steel, powder-coated frame, and contains a variety of components. The components include the membranes, filters, pump, electrical, and plumbing parts required for the reverse osmosis process as well as distribution. The Membranes are at the heart of the reverse osmosis process, and the number in use will vary based on the Matrix RO model. These membranes are semi-permeable, allowing water that is being purified to pass through it, while rejecting the contaminants that remain. The reverse osmosis process uses these membranes to separate and remove dissolved solids, organics, pyrogens, and submicron colloidial matter from the water. The process is called “reverse” osmosis since it requires pressure to force water across the membranes, leaving the impurities behind. Reverse osmosis is capable of removing 95% to 99% of the total dissolved solids (TDS), thereby providing safe, and pure water.

A .03 Micron, 20” Final-Filter has been added on all models produced from September 2010 and after. The .03 final filteris located on the upper-left side of the RO on the Product Line. There is a Sanitary Sampling Port, and the pressure across this filter will be displayed on the OIT. This filter uses a standard, 20” filter Housing, and should be changed every 6 months or if the ΔP reaches or exceeds 15 psi. A 5 Micron, 20”, Pre-Filter is also used to help reduce contaminants from the feed water to the RO. This filter is located on the lower-left side of the RO on the Feed Line, and the pressure across this filter will be displayed on the OIT. This filter should be changed every 30 days or of the the ΔP reaches or exceeds 15 psi. The RO uses a stainless-steel, multi-stage, centrifugal, Air-Cooled Pump which will automatically shut-off in a no water condition. This is a heavy-duty pump designed for years of service with proper operation. It is a vertical pump, mounted in the center of the RO rack. The pump works in conjunction with the Variable Frequency Drive (VFD). VFDs are reliable, easy to operate, increase the degree of flow control, and reduce pump noise. It is an electronic controller that adjusts the speed of the RO pump by modulating the power being delivered to it. This provides continuous control matching motor speed specific to the demand required by the pump. REMOTE ALARM BOX (optional) The RO Remote Alarm Box is a molded plastic box, usually located on the patient floor, in a position where it can be easily seen by clinic personnel during normal work duties. The box is equipped with audible and visual alarms that monitor the RO and Reservoir water level. The Remote Alarm Monitoring Box requires no external power supply, but receives 24vac power and signals from the RO which it is monitoring. This box has 2 RED lights; one that will illuminate when the RO goes into an alarm condition and one when the water level in the reservoir falls below the low-level sensor. The AMBER light will illuminate when and flash when the RO is in Disinfect Mode. AAMI standards require that the RO alarms be audible in the patient area. If the RO is located close enough to be heard in the patient area, the remote alarm may be omitted.

GENERAL REQUIREMENTS & SPECIFICATIONS 1. Floor Space: Level floor, minimum 48” x 48”. Sufficient space for installation, operation, and service 2. Water Connections: 1” female NPT threaded water connection with an adjacent shut-off valve 3. Drain Requirements: Sanitary drain capable of discharging 20 gallons per minute or better 4. Electrical Requirements: a. 208V – 230V models 3 phase, 30 amp, 60 Hz (3 hots, 1 neutral, 1 ground) b. 230V models 1 phase, 50 amp, 60 Hz (2 hots, 1 neutral, 1 ground) c. 460V models 3 phase, 15 amp, 60 Hz (3 hots, 1 neutral, 1 ground) 5. Operating Weight: 450-600 lbs 6. Loop: The distribution loop should be constructed of

materials that comply with current AAMI standards. The maximum distribution loop length for direct-feed systems should not exceed 700 feet. Installation should also comply with current AAMI standards.

7. Pressure The importance of monitoring and controlling the

feed water cannot be underestimated. Feed water pressure should be a minimum of 20 psi and no greater than 90 psi maximum. The minimum pressure must be maintained with the water flowing at the maximum required flow-rate.

8. Flow Rate The minimum flow-rate in gallons per minute is

based on the incoming pre-treatment equipment. 9. Chlorine / Chloramines Chlorine is commonly used as a disinfecting

agent in municipal water systems. Disinfection by-products can form when disinfectants, such as chlorine, react with naturally present compounds in the water. Chlorine/Chloramines in the feed water must be less than 0.1 ppm.

10. Silt Density Index Silt Density Index (SDI) is a measure of the

amount of suspended solids and colloidal materials in the feed water. High SDI values can lead to membrane fouling. A SDI of less than 3 SDI units is considered acceptable.

11. Turbidity Turbidity in water is caused by suspended and

colloidal matter such as clay, silt, finely divided organic matter, inorganic matter, plankton, and other microscopic organisms. Feed water turbidity must be less than 1 nephelometric turbidity units.


Page 12 of 93


12. Hardness Hardness is characteristic of feed water due to the presence of dissolved calcium and magnesium. Water hardness is responsible for most scale formation and can form insoluble residue in pipes and other water contact surfaces. Hardness is usually expressed in grains per gallon, parts per million, or milligrams per liter, all as calcium carbonate equivalent. Hardness level in the feed water must be less than 3 grains per gallon, or 51.3 parts per million.

13. Temperature Feed water temperature must be between 50o F

and 92o F. The optimum temperature is 77o F. The RO will shut-down at 93o F.

FAMILIARIZATION WITH THE OPERATOR INTERFACE TERMINAL (OIT) The Operator Interface Terminal (OIT) is the user’s primary means of controlling and monitoring the Matrix RO. It sends control commands to the PLC, allows the setup or changing of system parameters, and displays operational information, alarms, and system logs and trending information. At a glance it provides a current status of the system. OIT SCREEN SAVER The OIT has a screen saver function, that if there is no activity on the OIT for 15 minutes, the screen will simply go black. To awaken the OIT, simply touch only ONCE anywhere on the screen to reactivate the display, and allow time for it to wake up. MAIN SCREEN: Sub-Screens, Displays, Indicators, Function Buttons The Main Screen provides the user with a view of current status of the RO, operational control for primary functions, and access to operational and informational sub-menus. Each of these displays and controls will be described in detail below. EVENT / ALARM SCROLL BAR This display area, at the top of the Main Screen, scrolls the latest event performed or alarm encountered during the operation of the RO. Further information is available for these alarms and events from the Alarms or Logs Sub-Menus. CURRENT TIME DISPLAY This displays the current PLC time, and is used as the basis for triggering time-based events such as flush cycles and disinfection when the Auto-Start has been setup. This time is maintained by the system, and should not need to be reset after a power interruption, but can be changed by the user if necessary. - See the System Setup-Change Time section on how to change the time. MAIN-SCREEN BUTTON Pressing the MAIN SCREEN Button will display the Main Screen if the user has selected any of the Sub-Screens listed below.

NOTE: Press buttons only ONCE, then wait for the function to initiate. Pressing buttons multiple times can cause the CPU

to stall causing a noticeable delay in the execution of the selected process.


Page 14 of 93


SUB-SCREEN BUTTONS There are seven SUB-SCREEN Buttons that allow access to other operational and informational functions, which are discussed in detail later in this manual. - DATA Screen Button This screen displays in real-time the current operation information such as flows and pressures. - ALARMS Screen Button This screen allows the user to view the nature of alarm conditions to assist in correcting them. - DISINFECT Screen Button If a disinfect has been initiated by pressing the DISINFECT START Button, and the user has exited the disinfect monitoring screen, pressing this button will return the user to that same monitoring screen where they exiting from to continue monitoring the procedure. - LOGS Screen Button This screen provides a centralized means for viewing important events and alarms recorded in the log. - TRENDS MENU Button This screen allows the user to view certain operational values captured over a period of time and are displayed in a graphical format. - SETUP Screen Button This screen allows the user to access different levels of security protected system parameters. - HELP Menu Button This screen provides the user with multiple help screens based the many screens and functions available. WARNING INDICATORS A box on the Main Screen contains Warning Indicator Lights that flash in certain problem conditions. - Pre-Treat Interlock Open: Indicates the Pre-Treatment lockout is interrupted due to carbon or softener backwash/ regeneration. - Check Surge Suppressor Located in Junction Box #2: Indicates a problem with the 120VAC surge suppressor for the 120VAC/24DC transformer protecting the PLC in Junction Box #1. - Tank Cut Out Switch Activated Tank Has Filled: If both the top level switch and the middle level switch are OFF (OPEN), this light will flash. It will continue flashing until the water level reaches the bottom level and the level switch is turned ON (CLOSED). STATUS REPORT BUTTON When the STATUS REPORT Button is pressed the user may view the current operating parameters such as pressures and flow-rates as well as days since the last disinfect was performed. This data can also be saved to a SD card for offsite analysis. * See the Data Screen section for more information about the Status Report Screen ALARM RESET BUTTON Pressing the ALARM RESET Button temporarily turns OFF the audible alarm and alarm lights. This does not correct the cause of the alarm. Once pressed, the RO will attempt to retry the operation during which the alarm occurred, and in most cases the same condition will trip the alarm again after a short period time. Some situations will require the RO to shut OFF until the alarm condition is corrected.

MAIN SCREEN: Operational Buttons and Indicator Lights FLUSH START BUTTON and FLUSH INDICATOR LIGHT the flush cycle is a programmed sequence that pumps RO water through system at a preset time. The flush mode can be initiated anytime the user chooses or as part of a normal end-of-day procedure. Pressing FLUSH START Button will initiate this flush cycle, and can only be initiated if the OPER- DISINFECT Switch is in the OPER position. When this button is pressed the FLUSH INDICATOR Light will light up and display ON. When not in flush mode, the FLUSH INDICATOR Light will go out and display OFF. TIMED OPERATE START BUTTON and TIMED OPERATE STATUS INDICATOR LIGHT This function only works in Tank Mode and not Direct Mode, and only if the OPER-DISINFECT Switch is in the OPER position. It is usually done at the start of a shift to allow the user to perform water quality tests. Pressing the TIMED OPERATE START Button will start the RO for 30 minutes, and the TIMED OPERATE STATUS INDICATOR Light will light up and display ON. During this time the reservoir level controls will be bypassed as the RO produces water, and will simply go to drain if an overflow situation occurs. When this cycle is complete the level controls will return to normal mode, the RO to normal operation, and the TIMED OPERATE STATUS INDICATOR Light will go out and display OFF. OPERATE ON BUTTON, OPERATE OFF BUTTON, and OPERATE INDICATOR LIGHT If the OPER-DISINFECT Switch is in the OPER position, pressing the OPERATE ON Button will place the RO in operate mode, essentially turning it on to produce water as needed. When pressed, the OPERATE INDICATOR Light will light up and display ON. Pressing the OPERATE OFF BUTTON will take the RO out of operate mode, essentially turning it off. If off, the OPERATE INDICATOR LIGHT will not be lit and display OFF.

GENERAL CLEANING and DISINFECTING INFORMATION To perform at peak efficiency the RO system must periodically be cleaned and disinfected. The Cleaning Process is designed to remove mineral deposits that may build-up on internal surfaces. The Disinfecting Process is designed to significantly reduce bacteria and endotoxins that may build-up in the water and on the internal surfaces in the form of bio-film. The importance of regular and frequent disinfection cannot be minimized due to the risk associated with bacteria proliferation. CLEANING and DISINFECTING FREQUENCY As the manufacturer, Better Water LLC recommends that the RO be… … Disinfect and Clean when membrane fouling is indicated … Disinfect monthly … Clean quarterly Clinics may require more or less frequent cleaning and disinfecting, which is ultimately the Medical Director’s responsibility to determine and is typically based on water testing. Membrane fouling should be the primary trigger for performing this procedure indicated by the following signs: 1. The Product Flow decreases and the Reject Flow increases, and the two cannot be adjusted to design specifications. 2. The Water Quality Monitor indicates a continuous decline in water quality. Changes in the tap water pH, TDS, temperature, or pressure, can also cause significant changes in the overall performance of the RO. After 30 days, if no disinfection has been performed, the RO will periodically display a message to remind the user to do so. OUTSOURCED WATER TESTING A laboratory specified by the physician or Medical Director should perform chemical and microbial analyses as outlined in the current AAMI/ISO Standards to determine the current compatibility of the system with the feed water and the suitability of the system for providing product water meeting the AAMI requirements. This should be performed annually or more often if needed but, is it is ultimately at the discretion of the physician or Medical Director. WATER SAMPLING This RO is but a part of a total system designed to create AAMI quality water. As such, it is recommended that the water samples be drawn not only from the RO, but also from the other components in order to capture a complete view of the bio-burden impacting the system. Here are a few examples of these other sample points: - Municipal Feed Water - Pre-Treatment Water to the RO - Product Water from the RO prior to cleaning and disinfecting - Product Water from the RO after cleaning and disinfecting - Within the Distribution Loop - From the Reservoir


Page 24 of 93


The user should draw samples from the RO before and after the cleaning and disinfecting procedure in order to measure the effectiveness of the cleaning and disinfecting process. Copies of the test results should be filed and available for review. TESTING FREQUENCY Better Water LLC recommends bacterial testing should be performed once a month on the RO product water by a qualified microbiological laboratory. More frequent bacterial testing should be performed if the system has undergone repair or if the results of the cultures exhibit higher than allowable counts. Testing may increase or decrease at the discretion of the Facility Medical Director. RESIDUAL CHEMICAL TESTING Users should refer to the chemical agent manufacturer to determine the appropriate method for testing for residual chemical substances in the water after cleaning and disinfecting. The water must be clear of detectable levels of cleaning and disinfecting agents prior to use with patients GENERAL INFORMATION The cleaning process for the Matrix TM System is designed to remove calcium and other mineral deposits or scale by using a 1% to 5% acidic solution. The RO was built with components that will tolerate Peracetic acid type disinfectants.

Facilities that have more than one distribution loop may have to clean, disinfect, and rinse each loop separately. The unit must be thoroughly rinsed prior to initiating a cleaning/disinfecting cycle.

WARNING Chemical cleaners and disinfectants can cause serious injury or death.

Proper protective equipment must be used.

The preparation of these chemical solutions must be done in accordance with the

specifications established for the particular chemical.

These chemical solutions must be handled in accordance with their Material Safety Data Sheet (MSDS).

These procedures should be performed by trained and qualified technicians.

WARNING Do not disinfect or clean the RO system or distribution loop while patients are

dialyzing.

CAUTION The membranes will not tolerate sodium hypochlorite (bleach).

CAUTION It is recommended that you routinely disinfect the membranes every 30 days with an approved disinfectant that will not degrade the membranes or the components of the

RO.

SAMPLE COLLECTING from a SANITARY SAMPLE PORT In an effort to allow accurate bacterial testing of the product water from the RO, the Sanitary Sampling Port was added to all models produced August 2010 and later. - Sample Ports on RO’s produced before August 2010 SHOULD NOT be used to collect samples for bacteria cultures or LAL’s. These sample ports should only be used to measure TDS only. - The new Sanitary Sample Port can also be used for TDS measurement and AAMI samples. PROCEDURE 1. Put on surgical gloves (or similar) and a face shield. - NOTE: Failure to do so may result in inaccurate and/or false readings from the sampling. 2. Flush the Sanitary Sample Port with water by removing the Luer Lock Cap and twist the valve until a steady Stream of water exits the sample port. Let the water flow for a minimum of 2 minutes, then close the valve. - NOTE: Do not misplace the Luer Lock Cap. 3. Prepare a 10cc syringe with the supplied injection needle, and draw into the syringe 10 cc of 70-90% isopropyl alcohol. 4. Inject the alcohol into the sample port. When the Injection is complete, replace the Cap and let dwell for 10 minutes. 5. After the 10 minute dwell is complete, remove the cap and wipe the outside of the port with an alcohol wipe. 6. Allow the alcohol to air dry, usually within 30 seconds after application. 7. Twist the valve until a steady stream is present. - Flush at least 1000 ml from the port, then close the valve. - Discard this water. - This ensures that the port (internally) has been rinsed of alcohol residue and possible endotoxins left from the disinfection. 8. Prepare a sample cup for sampling, and place it cup under the valve - Open the Sanitary Sample Port slowly to collect the sample. - Avoid splatter which could cross contaminate the sample. - Do not allow the cup to touch or come in contact with the Sanitary Sample Port. 9. Close the valve when enough sample has been taken. - Immediately replace the lid on the sample cup. - Avoid sample cup cap contamination by coming in contact with any external surfaces. - Replace the Luer Lock Cap on the Sanitary Sample Port. 10. Follow appropriate procedures for collection of samples with Accu Vials for colony count and LAL.

USER ADJUSTMENTS On occasion, the RO may require adjustments that can be performed by qualified operators. There are many factors that can affect the performance of the RO. If minor adjustments to the RO do not produce the desired results, investigate changes in the tap water feeding the RO. Tap water pH, temperature, pressure, TDS, and flow changes can cause a reduction in the RO performance. In worst case situations, changes to the tap water can create conditions the RO cannot handle without supplemental water treatment. USER ADJUSTMENTS: VARIABLE FREQUENCY DRIVE VFD – Adjusting Product and Reject Set-Points The VFD is pre-programmed with operational parameters set by Better Water and locked out to the end user. If trouble shooting VFD issues Call Better Water for technical assistance. The VFD set point and Product/Reject flow are set by turning the ADJUSTMENT Wheel. - To properly set the correct set point and Product/Reject of the RO, the RO must be on and running. - Run the RO for 5 minutes before setting the set point. The set point relates to the desired product and reject flow of the RO. - To calculate the flow count: - Example: A 4 membrane array RO will be set at 5 gpm Product and 5 gpm Reject at 50% recovery. - Number of membranes x 1.25 gpm = Rated Product Flow 4 membranes x 1.25 gpm = 5.0 Rated Product Flow - At 50% recovery the Reject flow will 5 gpm as well. When setting the correct flow, the Post Filter pressure should be at 40 psi on the RO when making the adjustment. If not, adjust the Post City Boost VFD on the Pre-Treatment. - Turn the ADJUSTMENT Wheel to set the desired Product flow and set point. - Once set then push ENT Button. - FC will appear briefly in the display and then the display will read actual frequency the RO Pump is running at. - If the ENT is not pushed the VFD will revert back to the original set point.

CAUTION Only qualified RO operators should make adjustments to the unit. Before making any adjustments, read this entire section and pay close attention to cautions, notes, and items marked important. While making adjustments, the RO must be running with no alarm conditions indicated. The inlet water temperature must be 70-92°F with 77°F being optimum. The temperature must be measured while the RO is in normal operation. The RO inlet water pressure must be >40 psi while flowing at the rate specified for this unit. See Unit Specification Sheet.

VFD – Breaker The VFD breaker is located in Junction Box # 2. If the breaker has tripped the RO Pump and VFD will not operate. This breaker will shut off power to the VFD to prevent damage to the VFD and the RO PUMP. VFD – Transducer The VFD transducer is threaded into a tee located post RO Pump/pre membrane. The transducer communicates with the VFD to maintain the set point by analyzing pressure differentials pre and post RO Pump. For example, if the pre or post RP Pump pressure drops the transducer transmits that signal to the VFD. The VFD will increase the frequency to compensate for the pressure loss and will try to maintain set point and Product/Reject flows. The same is true if the pre or post RO Pump pressures increases the transducer signals the VFD to decrease frequency. USER ADJUSTMENTS: PRODUCT and REJECT FLOW Peak efficiency for the RO is based on the Product and Reject Flow. The Reject & Product Adjustment T-Handle located on the front of the RO is used to make this adjustment. This procedure describes how to adjust both Product and Reject Flow. 1. Press the DATA SCREEN Button on the MAIN Screen to display the current operating information. 2. Locate the Reject & Product T-Handle on the Reject/Product Regulating Valve, and turn it slowly either clockwise or counter-clockwise adjust the flows. The goal is to balance or get the product and reject flows as close as possible. - Examples: Product Flow = 5.0 gpm; Reject Flow = 5.0 gpm; Recovery = 50% 3. After the Reject and Product Flows have been balanced, perform a Quality Assurance Check on the RO to insure all pressures and flows are within design specifications. USER ADJUSTMENTS: RECIRCULATION FLOW There is no recirculation flow adjustment on this RO. It is pre-set by the manufacturer. USER ADJUSTMENTS: MEMBRANE PRESSURE 1. Open the VFD Control Box. 2. Turn the ADJUSTMENT Wheel to increase and decrease membrane pressure. USER ADJUSTMENTS: REJECT PRESSURE There are no requirements to adjust the Reject Pressure. The Reject Pressure is used solely to monitor the pressure drop across the membrane.


Page 58 of 93


USER ADJUSTMENTS: PRODUCT PRESSURE If a Tank Feed System, there are no requirements to adjust the Product Pressure. For Direct Feed Systems the Product Pressure should be adjusted only when there are no requirements for RO water. 1. Locate the Pressure Bypass T-handle at the end of the distribution loop. 2. Turn the T-handle clockwise to increase product pressure, and counter-clockwise to decrease product pressure. - Maximum product pressure is 70 psi. - Product pressure must be 10 psi greater than feed water/5 micron filter out pressure to the RO Adjustments on feed water pressure may be required before attempting to adjust product pressure. - EXAMPLE: If the Feed Water/5 micron Filter Pressure is at 40 psi, then the Product Return Pressure should be set to 50 psi. USER ADJUSTMENTS: FLUSH TIMER Normally, the RO Membranes should be flushed four to six times per day. If the facility’s operation is considered less than normal (less than 6 days a week operation), it is recommend that the frequency of the flush cycle should be set to occur once every four to six hours for 15 minutes. These flush cycles activate only when the RO has been placed in flush mode by the user. The flush frequency and duration are set on the SETUP FLUSH TIMERS Screen which is accessible via the SETUP Screen. * See the SETUP SCREEN-Flush Timers section for detailed instructions.

CAUTION The time that a FLUSH CYCLE is scheduled should not coincide with the backwash or regeneration of any pre-treatment component. If the two should occur simultaneously, it could trigger a LOW PRESSURE ALARM due to insufficient water pressure and insufficient quantity being available to meet the demand.

SYSTEM MAINTENANCE, Change Membranes and O-Rings Better Water LLC, recommends that the membranes be changed if low flow rates or percent of rejection fall below operational parameters after cleaning. The life of an RO membrane is dependent on many factors such as feed water quality, properly operating pre-treatment and routine maintenance such as membrane cleanings and disinfections. Normally, you can expect the membranes to last from 3-5 years or more. Eventually, you will need to replace membranes and the following should be used as a guide for this procedure. For Older Model ROs: RO models manufactured prior to September 2006 were made with different membrane housings than the fiberglass ones used currently. If ordering replacement membranes and O-rings for these ROs refer to the information below or call Technical Support for assistance. For ROs with Stainless Steel Housings: - Spacer adapters are required to make the membrane properly fit because this housing is slightly different in size. The Inner O-ring is different as well. - Membrane replacement kit which includes the Membranes and Adapters: EQSUBMEM001 - Inner End-Cap O-Ring: EQFHOO01588 - Outer End-Cap O-Ring : EQFHOO01587

CAUTION Failure to follow these instructions can result in voiding the membrane warranty.

NOTE It is recommended that the O-Rings be replaced when the membranes are replaced,

and that medical grade glycerin be used as a lubricate because of its water-solubility.

PREPARATION 1. Make sure that there are no requirements for RO water (no patients are dialyzing). 2. Turn the RO OFF and unplug or disconnect from the main power source. 3. Turn OFF the RO Inlet Valve from the Pre-treatment. 4. Depress the red pressure relief button on the Big Blue Pre-Filter to the RO to relieve the pressure. UNPACK MEMBRANES 5. Open and unpack the membranes from their shipping cartons. 6. Verify Correct Membranes - Before opening the boxes of the new membranes, verify that they are the correct membranes for your RO. - If they are not the correct membranes, DO NOT ATTEMPT to install them. - A “RO MEMBRANE” label should be adhered to the box. This label will have a received date. Membrane is good for one year from this date. - Each membrane is also labeled with an individual serial number which should be recorded and also noted in which membrane housing the specific membrane will be installed. 7. Open and Unpack the New Membrane - Open the membrane box. - If the membrane was ordered with adapters which are required for older model housings, these adapters will be in one end of the box, so don’t discard the box without retrieving these. - Remove the bagged membrane from the box discarding the packing material. - Do not open the bag containing the membrane REPLACE MEMBRANES 8. Remove the end-cap clamps - On the top of the membrane housing, locate the 2 metal clamps that secure the membrane end cap. - Loosen and/or remove the Allen Screws securing the end cap. There are 2 clamps and Allen screws on each end cap. - After removing the Allen Screws (or loosening them enough for the clamps to be removed, slide the clamps toward the center of the membrane housing until they are released from the groove in the membrane housing.

9. Remove the Compression nut and Blue Tubing. - Locate and loosen the compression nut on the top of the end cap that secures the blue tubing. - It is only necessary to remove the outermost nut, and this should only be hand tight. - It is NOT necessary to remove the entire compression fitting from the end cap. - Remove the Compression nut, leaving it attached to the blue tubing. - Move this tubing out of the way. 10. Remove the End Cap - With the metal clamps and smaller blue tubing removed, grasp the larger blue hose and firmly wiggle the hose and end cap back and forth while pulling up to remove the end cap from the housing. - Move the end cap (still attached to the blue hose) out of the way. - NOTE: If the end cap is too tight and will not move, refer to Alternate Membrane End Cap Removal Procedure, detailed below. 11. Remove the Old Membrane - Reach into the membrane housing and grasp the membrane by the membrane adapter and gently pull the membrane out of the housing and discard. - It may be necessary to grasp the membrane adapter or one of the “spokes” with a pair of needle nose pliers to pull it out. 12. Install the New Membrane - CAUTION: As stated before, the new membrane is packed in a liquid preservative, so take caution in handling to prevent slippage and exposure to prevent injury. - This preservative can be drained from the packaging into a suitable container and transferred to a drain, or… - This preservative can be poured into the membrane housing as the membrane is being installed. - Install new spacer adapters into each end of the membrane if required, based on the membrane housing. - Hold the membrane, still in the foil bag, upright above the membrane housing, with the open end of the foil bag down. - Slowly and gently allow the membrane to slide through the foil bag and into the membrane housing. - CAUTION: DO NOT allow the membrane to quickly drop into the membrane housing, as this can cause damage to the membrane adapter.

ALTERNATE MEMBRANE END-CAP REMOVAL PROCEDURE, USING “TEE-HANDLE TOOL” After the RO has been in use for several years, you may find it difficult to remove the end cap by just pulling on the blue hose in which case follow the following steps: 1. After removing the metal clamps and the compression nut securing the blue tubing, remove the compression fitting that is threaded into the end cap by using a socket wrench. 2. Remove any excess Teflon tape from the socket that may have been left. 3. Insert a “Tee Handled Removal Tool” into the end cap, where he compression fitting was. - CAUTION: DO NOT OVERTIGHTEN the stainless steel nipple, as this can crack or split the end cap. - Only thread the nipple in a few turns or until it is snug. 4. Grasp the Tool and move it back and forth while pulling upward to break the end cap loose and remove it.

5. Clean any old Teflon tape and/or pipe dope from the compression fitting that was removed. - Wrap only 3-4 wraps of new Teflon tape on the threads of the compression fitting. - Apply a very small amount of Teflon pipe dope to the threads/tape. - Re-install compression fitting in the end cap, being extremely careful not to over-tighten as this can crack or split the end cap.

NOTE It is recommended that a "Tee-Handle Removal Tool" be fabricated to facilitate membrane removal.
