Description


www.betterwater.com

DESCRIPTION Your Post-Treatment System has up to four Pyrogen Filters that are enclosed in special vessels to process RO Product water or DI water and provide an extremely high recovery rate. This Post-Treatment System is not intended for any other application. The Ultra-filtration process is similar to a Reverse Osmosis Machine. Your Post-Treatment System works from system water pressure boosted with on-board boost pump(s), Units with spiral wound membranes will have a small amount of waste or reject water going to drain. Filter cartridges will not. The output (product) water from the Post-Treatment System is affected by other components in the water treatment system; namely, pressure, temperature and flow-rate. The Pyrogen filters in the Post-Treatment System are of the highest quality known. Pyrogen filters are a consumable product. The life of the filter is directly related to the monitoring and routine care programs you maintain in your facility. A Post-Treatment System, in conjunction with good disinfecting programs, is the most effective means of controlling bacteria and endotoxins in the post treatment and distribution segments of a water purification system. Pyrogen filters can reject bacteria and endotoxins, whereas, submicron filters and ultraviolet irradiators are effective for bacteria alone.

VFD Operation & Adjustment


www.betterwater.com

TOSHIBA VFD OPERATION Beginning July 2010 an optional VFD for the Post Treatment Rack and Wall Mount Ultra Filter assemblies is offered by Better Water LLC. The VFD was added for energy savings as well as maintaining proper flow velocities through the RO water loop.

AAMI states the flow velocity minimum for a Direct Feed Loops is 1.5 ft/s. However, for indirect feed (storage tank fed) systems the recommended flow velocity minimum is 3 ft/s. (See next page for GPM required for 3ft/sec.

VFD Control Panel Operation.

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. Located on the VFD front panel are 2 arrow keys, an UP arrow key and a DOWN arrow key. Also located on the Front panel is a display, a RUN and a STOP button (which are inactive during operation) along with the MODE and ENT (ENTER) buttons.

The VFD set point and loop Product flow is set by using the UP or DOWN arrow keys (TOSHIBA model only). To properly set the correct set point for loop flow, push either the UP arrow key or the DOWN arrow key to set desired flow. When desired set point is reached, push the ENT (enter) button. FC will appear in the display. Push either the UP arrow key or DOWN arrow key and verify the set point. Push ENT (enter) button again to complete the operation.

Resistivity Monitor


www.betterwater.com

Resistivity Monitor For Post Treatment Rack It is recommended the Post Treatment Rack Resistivity Monitor be tested on a quarterly basis (every 3 months) to ensure proper operation in the event the operator has to go onto emergency D.I. Beginning January 2012 the Post Treatment Rack will have divert to drain (DTD) 3 way ball valve built onto the rack. The Resistivity Monitor however will be wall mounted in close proximity to the DTD valve. How To Test The DTD.

1. Plug Resistivity Monitor into a 115 VAC outlet. If testing with RO water the DTD will alarm and the valve will be diverting to drain.

2. Open the Resistivity Monitor control box. Locate the SET/MEASURE/CHECK switch located on Resistivity Monitor. It will be set to MEASURE ( center position). SEE FIG. 1.

3. Push the switch to the right to the CHECK position ( right position). SEE FIG. 2. After 90 seconds the DTD valve will go back to the loop outlet position and the drain will shut off.

4. Push the switch to the far left to the SET position FIG 3 then look at the display FIG 4. NOTE: The DTD valve will open back to drain and the Alarm will resound. It should read 1.2. If adjustment is required below the SET/MEASURE/CHECK to the lower left there are 2 pot screws labeled SET and CHECK. Adjust the SET screw until 1.2 is set in the display. Next check the Resistivity Alarm Box on the patient floor for Poor Quality light and audible piezo alarm.




Page 23 of 53

Resistivity monitor Con’t


www.betterwater.com

5. Push the switch back to the far right to CHECK again and verify the CONSTANT CHECK value FIG 5. Located on the probe wire next to the probe assembly there is CONSTANT value recorded for the probe FIG 6. An example would be C= 0.970. Look at the display it should read whatever CONSTANT value is recorded on the probe. If the CONSTANT has changed adjust the CHECK set screw until the value matches the probe value.

6. When the CONSTANT value check is completed let the DTD valve go back to the loop outlet position leaving the switch in the CHECK position FIG 2. Verify the DTD valve has gone back to the loop outlet position by looking at the loop return flow meter and for water flow from the loop is returning back to the storage tank. Go to the patient floor and check the Resistivity Alarm Box for a Good Quality light and no piezo alarm. Unplug the Resistivity Monitor. Test is complete.


Page 24 of 53

Resistivity Monitor Con’t


www.betterwater.com

Testing The Dtd Valve With D. I.

1. Have D.I. tanks online to perform this test. Plug the Resistivity Monitor into a 115 VAC outlet. If poor water quality exist the DTD valve will divert to drain and a alarm will be audible. Located on the bottom Resistivity Monitor is a toggle switch labeled AUTO and TEST. Make sure the toggle switch is set to AUTO.

2. When the water comes to good quality and the rinse up period completes then the DTD valve the will be in the loop outlet position. Verify the DTD valve has gone back to the loop outlet position by looking at the loop return flow meter and water flow from the loop is returning back to the storage tank.

3. Located on the bottom Resistivity Monitor the toggle switch should be set to AUTO. When the water Resistivity is greater the 2 MΩ/cm set the toggle switch to TEST. The DTD valve will go to drain and the alarm will be audible. Go to the patient floor and verify the Resistivity Alarm Box is in Poor Quality and there is a audible piezo alarm audible to the staff.

4. Set the toggle switch back to AUTO. If the Resistivity is still above 2 MΩ/cm the DTD valve will stop diverting to drain after 90 seconds. This is a delayed rinse up period. This time cannot be altered by the end user.

5. The Post Treatment Rack is now ready for D.I. use.

Conductivity Monitor


www.betterwater.com

Post Treatment Final Water Quality Conductivity Monitor The Post Treatment Final Water Quality Conductivity Monitor is for monitoring water quality going out to the loop. The Monitor is factory calibrated with a matched probe from the manufacturer. If a replacement is required the old probe cannot be used with a new Monitor. When ordering a Monitor a probe will with the Monitor. Part Number for the Monitor is EQMOBO01305. If the Monitor is replaced follow the set up procedure below. SETUP AND ADJUSTMENTS

1. Upon completion of installation the Monitor has to be setup.

2. Push the SET button. C=1.000 will be in the display. The button scrolls the button changes the number.

3. Look at the probe that comes with Monitor it will tag taped close to the probe. Example: It will read C=0.977. The Monitor says C=1.000 so it has to be changed to our example C=0.977. Push the button to remove the 1. Next push the button to scroll to the next number and change 0 to a 9 with the button. Repeat the same for changing the next two numbers. When finished push SET button to go to the next setting.

4. The next setting is the Alarm Set Point. The display will read 1999 µS/cm. Set this to 1050. Using button to change the number and the button to scroll to the next number. When the set point has been set then push the SET button twice to exit.

5. The display will the conductivity of the water in µS/cm as the default. If ppm is preferred push the button once and display will read in ppm.

The alarm set point is actually 105.0 µS/cm or 50.0ppm not 1050 µS/cm or 500ppm. If a lower set point is desired go to the set point display to change it. Do not change the C=####. Example if the new set point needs to set at 25.0ppm you need to convert ppm to µS/cm. So multiply 25.0 ppm X 2.1 = 52.5 µS/cm. So in the set point display that would be 525 µS/cm = 52.5 µS/cm = 25.0ppm. To convert µS/cm to ppm divide by 2.1. If you want to convert ppm to µS/cm mulitiply by 2.1. The alarm set point will always be in µS/cm not ppm. The Alarm Set-Point of the Final Water quality Monitor should be set to 4x the R.O. Product Water conductivity. On Better Water R.O.s, the conductivity is displayed PPM(TDS). The Final Water Quality Monitor displays in µS/cm2. To convert PPM to µS/cm2: PPM x 2.1 = µS/cm2.

DISINFECTING THE DISTRIBUTION

SYSTEM AND SPIRAL WOUND

FILTERS/ Absolute Pyrogen Filters

The use of household bleach (5.25%) is common for use in disinfecting water treatment systems and Bicarb delivery systems for hemodialysis. Bleach is a cost effective disinfectant and generally produces satisfactory results. Varying concentrations of Sodium Hypochlorite (bleach) are used among dialysis facilities for disinfection. DILUTIONS:

1. 5.25% household bleach is 50,000 ppm Sodium Hypochlorite

2. 6% household bleach is 60,000 ppm Sodium Hypochlorite

3. 1:1000 Dilution: 5.25%=50 ppm and 6% = 60 ppm. 4. 1:500 Dilution: 5.25%=100 ppm and 6% = 120 ppm. 5. 1:100 Dilution: 5.25%=500 ppm and 6% = 600 ppm. 6. 1:50 Dilution: 5.25%=1000 ppm and 6% = 1200

DISINFECTING The Post-Treatment System is disinfected as a component of the Distribution segment of the water treatment system. There are no unique disinfecting requirements for the Post-Treatment System when utilized in this mode of operation. The disinfecting schedule is determined by the Medical Director and the results of bacteria and endotoxins test. Recommended disinfecting solutions for loop/Post-Treatment system: 1. The manual over ride on the divert-to-drain MUST be engaged before disinfecting the water loop 2. A 500 ppm solution of sodium hypochlorite. To make this solution, add 1000 cc’s of 5.25% sodium hypochlorite (household bleach) to 230 gallons of R.O. water in the storage tank. Make sure to the water is flowing through the trapped overflow. * Recommended dwell time: 30-60 minutes. NOTE: The spiral wound ultra-filters are rated at 5000 ppm hour days with proper disinfection. This means that when disinfecting with a 500 ppm Sodium Hypochlorite solution, the ultra-filters would be rated at 240 hours dwell time. As you can see, the ultra-filters have a high tolerance to oxidizers, however, Better Water recommends replacing the 4x40 ultra-filters every 3 years under normal operating conditions. The cartridge based filters should be replaced every 6 months.

3. A 1% Renalin / Minncare solution (1 quart per 25 gallons of R.O. water) may also be used. The recommended dwell time is 2-4 hours. NOTE: When calculating dosage of disinfectants, one must consider water volumes in the loop piping, cartridge filter housing, 4x40 filter housings, etc. A common practice is to make a larger solution than needed to disinfect and discharge the solution to drain through the loop return-to-drain valve until the proper residual has been obtained, then close the loop return dump valve and let the solution return to the storage tank.

Beginning January 2010 an optional UV light was offered for the Post Treatment systems. When disinfecting the UV light needs to be off or unplugged. Failure to turn off the UV light during disinfection will cause the UV lamp intensity sensor to fail along with damaging the quartz sleeve. When disinfection is completed turn UV light back on.

Disinfect and Rinse Operation


www.betterwater.com

Disinfect/Rinse Operation: Beginning January 2012 for Disinfecting and Rinsing the Post Treatment Rack the operator will use the OPER/DISINFECT key switch on the front control panel. In this mode the UV and Conductivity Monitor will turn off. The pumps will auto cycle every five minutes so the operator does not have manually cycle the Repressurization pumps during the disinfect and rinsing associated with disinfection. The storage tank now has an inductor for drawing the disinfectant into the storage tank without the operator having to open the lid to pour the disinfectant in. The PRV for the Spray Ball has also been relocated lower so the operator doesn’t have to climb to the top tank for adjustments.

1. Turn the AUTO/MANUAL selector switch to OFF. Make sure the PUMP #1/PUMP #2 selector switch is OFF.

2. Turn the OPER/DISINFECT switch to DISINFECT. PUMP #1 will start first then 5 minutes later PUMP #2 will start and alternate from that point. Check the UV is off and the Conductivity Monitor is off.

3. Prepare the amount of disinfectant to be used. See dilutions. Connect the draw tubing to the quick disconnect of the Inductor but DO NOT place in the disinfectant.

4. Now close the Inductor bypass valve to ¾ to fully

closed position. Look at the Loop Return Flow Meter for air bubble if air bubbles are present. If no air bubbles is present close the Inductor Bypass Valve. Then adjust the Spray Ball PRV to 10 to 5 PSI. Bubble should become present. Next slightly crack open the Inductor Bypass Valve but not to much to eliminate the air bubbles. You want to see a steady flow of air bubbles going the Return Flow Meter.

5. Now place draw tubing into disinfectant and verify draw. When disinfectant draw is complete disconnect the draw tube from the Inductor. Next crack the Inductor Ball Valve to ½ to 1/4 open. Next reset the Ball Spray PRV to 20 to 25 PSI.

6. Proceed with disinfection rinsing. 7. When disinfection and rinsing is complete turn the

OPER/DISINFECT key switch back to OPER. Select AUTO on the AUTO/MANUAL selector switch. The Repressurization pump will restart, the UV will come on, and the Conductivity Monitor will power back up.

8. When AUTO is selected the pumps will cycle every 6 hours. The time cycles for each pup is as follows:

12:00am to 6:00am PUMP #1 6:00am to 12:00pm PUMP #2 12:00pm to 6:00pm PUMP #1 6:00pm to 12:00am PUMP #2

Relocation of Wire on Replacement VFDs TSB 2012010

Created/Last Revised Date 11/09/2012

Last Reviewed Date 11/09/2012

Page 1 of 1

OVERVIEW: The manufacturer discontinued the model of the VFD used in Better Water LLC’s 3046 ROs and Post-treatment devices in October of 2012. The replacement model is functionally the same with the exception of the use of one of the terminal posts and the location of grounding posts, both requiring the relocation of wires if the old model VFD is replaced with the new model. Better Water LLC’s part number of EQMOBO01350 which is the “3 Phase-In / 3 Phase-Out / 5 Horsepower VFD“ will remain the same. The difference between these two models is mostly cosmetic. See the pictures below of the old and new models.

TERMINAL POST & GROUND WIRE RELOCATION: 1. Turn off the power, and unplug the device from the electrical outlet before opening the control box. 2. On the old model VFD, take note of the location of the wire (from the pressure transducer) on the terminal

post labeled VIA and where the three ground wires are located. 3. Replace the old model VFD with the new model VFD, reconnecting the wires with the following exceptions.

4. On the new model VFD, relocate the wire (from the pressure transducer) to the terminal post labeled VIC. 5. Relocate the three ground wires to the three grounding posts on the bottom of the new model VFD.
