23G-Series RO System 5.0 MACHINE OPERATION AND MAINTENANCE Proper maintenance of the 23G RO system in accordance with this manual and good medical practices is essential when the system is used in a medical application for water purification for use in hemodialysis. FAILURE TO FOLLOW THE REQUIREMENTS SET FORTH IN THIS SECTION AND GOOD MEDICAL PRACTICES COULD POSE A RISK OF SERIOUS INJURY OR DEATH TO HEMODIALYSIS PATIENTS.
23G-Series RO System WARNING: Determination of microbial culturing and disinfection frequency is the responsibility of the operating facility. Failure to conduct timely microbial culturing and disinfection could pose a risk of serious injury or death to hemodialysis patients. 1. Observe and record hardness level in the feedwater to the RO (for systems with softener pretreatment).
23G-Series RO System 8. Observe and record the percent rejection and permeate conductivity displayed on the ECM-100 display. 9. Measure and record the feed water temperature on the Operation Log. A hand held thermometer may be used. The water temperature has a significant effect on the flow rate of the RO membrane. 10. Flushing The machine should be flushed daily to remove sediment from membrane surfaces.
23G-Series RO System 5.4 Quarterly Requirements 1. Clean/sanitize the membrane elements. Refer to Section 5.8 for the membrane cleaning/sanitizing procedure. Cleaning/sanitizing the machine is vital because contaminants and/or biological materials accumulate on the membrane surface potentially reducing the permeate flow rate and affecting the permeate quality. A layer left on the membrane may cause permanent damage and reduce membrane life.
23G-Series RO System 5.5 Semi-Annual requirements 1. Tighten all electrical screws in the control box. NOTE: Disconnect from both sources of power prior to opening control box. 2. 5.6 Tighten high voltage wires to motor starter. Annual Requirements The actions below should be performed in addition to the monthly requirements. 5.7 1. An AAMI Water Quality Analysis of the product water should be conducted at least yearly. 2. Check the ECM monitoring for accuracy. Recalibrate as necessary. 3.
23G-Series RO System CAUTION: Do not operate the machine with more than 30% additional concentrate flow without prior approval from Mar Cor Purification. Operation above this flow rate may damage the pump and motor. 2. 5.8 Use the AUTO-ON commands in the Timer Presets Menu (03) of the ECM-100, to flush the machine automatically during extended shutdown periods (over 4 hours). If using the AUTO-ON command, the machine must be in the AUTO mode.
23G-Series RO System NOTE: Cleaning may be required as often as once every week or infrequently as every quarter, depending upon the local water supply conditions. For more information, or for instructions on long-term machine shutdown (greater than 72 hours), contact your equipment supplier. Read and understand all instructions prior to beginning procedure.
23G-Series RO System 3. Hook up the CIP feed hose to the quick connect fitting on the pump. Hook the other end of the hose to the quick connect fitting on the CIP tank. 4. Place the CIP skid near the 23G so all CIP lines will reach CIP ports on the machine. 5. Connect the feed permeate and concentrate lines to the CIP tank quick connect on CIP pump and then to the CIP port on the machine. Open the CIP valves on the machine. 5.8.2 Cleaning/Sanitizing with 23G CIP 1.
23G-Series RO System 10. Return to the ECM-100 controller and push the HAND/AUTO button to HAND. The Hand Mode light will illuminate. Push the On button, and both the 23G pump and the 23G skid pump will start. See Cleaning in the 23G Operator’s Manual for cleaning instructions. NOTE: The CIP system must provide positive feed pressure to the RO machine. Mar Cor Purification strongly recommends using a CIP pump to provide sufficient inlet pressure (20 - 30 psi [1.38 - 2.
23G-Series RO System CAUTION: Do not leave cleaning solution in the machine for a period longer than one hour. The cleaning solution may damage the membranes and the machine during an extended period of contact. 17. To flush the cleaner from the machine close the CIP inlet valve. 18. Open the inlet feed valve. 19. Open the CIP tank drain valve. 20. Permeate and concentrate will continue to flow to the CIP tank and then to the drain. 21.
23G-Series RO System 5.9 Sanitizing Using a CIP System WARNING: Determination of microbial culturing and disinfection frequency is the responsibility of the operating facility. Failure to conduct timely microbial culturing and disinfection could pose a risk of serious injury or death to hemodialysis patients.
23G-Series RO System • The peracetic acid-based chemical solution is mixed with water free from iron and other transitional metals. RO water is preferred. • The peracetic acid-based chemical solution temperature is kept at or below 77°F (25°C). Ice or other cooling methods may be required to keep temperature down. • The PA membranes’ exposure to the peracetic acid-based chemical solution does not exceed one hour per week at a chemical solution concentration of 1%.
23G-Series RO System 2. Remove the pre-filter bowl by rotating it counterclockwise. 3. Remove the old filter. 4. Install the new filter. 5. Re-install the pre-filter bowl. NOTE: Failure to change pre-filters may void machine warranty. 5.12 Recording Performance Data Operating performance data should be recorded daily and kept on file or submitted to your equipment supplier or Mar Cor Purification. Copies of data sheets will be required by Mar Cor Purification if a warranty question arises.
23G-Series RO System 5.14 Membrane Element Replacement As time progresses, the efficiency of the membrane elements will begin to decline. Generally, the salt rejection of the membrane will not change significantly when properly operated on water until about two years after installation. Under ordinary conditions, the permeate rate may decline slightly after one to two years of operation. This period can be extended with frequent flushing and cleaning as outlined in these instructions.
23G-Series RO System CAUTION: Upon start-up of a new machine or installation of new membranes machine must be operated with permeate running to drain for a period of 3 hours in order to flush out all membrane preservatives. Failure to properly flush the membranes can result in patient safety issues. If the 23G RO machine is going to be disinfected rinse the system to drain under normal pressures for a minimum of one (1) hour before exposing membranes to Minncare®.

If the 23G RO machine is going to be disinfected, rinse the system to drain under normal pressures for a minimum of one (1) hour before exposing membranes to Minncare®. Flush the system to drain under normal pressures for a minimum of six (6) hours before exposing membranes to formaldehyde.
23G-Series RO System CAUTION: The flow control orifice valves are sealed to prevent tampering, and should not be adjusted by unauthorized personnel. Damage to the machine may occur and physical injury is possible. • The flow control orifices are factory set; according to the design specifications of the machine. • Adjustment of the orifices in the field are permitted only with the approval of the equipment supplier.
23G-Series RO System 5.15.1 Leaks During adjustment it is normal for a very small amount of water to leak from under the larger nut of the orifice, and/or from around the locking nut on the orifice adjustment screw. • To correct leaking under the large nut, the two O-rings need to be replaced. Contact your equipment supplier for assistance. • Any other leaks on the machine should be corrected promptly. Any cracked or broken fittings must be replaced. Contact your equipment supplier for assistance.
23G-Series RO System Do not make adjustments when the Autoflush light is ON. Always wait until the Autoflush finishes and the light goes out before adjusting the orifices. Make sure concentrate valve is closed. 1. Concentrate Orifice - screwdriver adjustment. • Adjusts the concentrate flow output to the drain. • Adjust so that the concentrate flow rate matches the value printed on the machine nameplate.
23G-Series RO System Adjusting the Orifices - requires two wrenches and a large screwdriver. a. Use one wrench to hold the large nut and prevent it from turning. b. Use another wrench to loosen the locking nut, adjust the flow with the screwdriver. c. Tighten the locking nut after. • While adjusting, make sure the pump boost pressure (primary pressure less pre-filter pressure) reading never goes outside of value listed in Section 1.8.4. • Clockwise (in) increases primary pressure and permeate flow rate.
23G-Series RO System 5.16 Permeate Divert Factory-installed valves divert the RO permeate to drain for a preset period of time upon machine start-up or when the RO permeate exceeds a preset conductivity level. This optional feature ensures good quality water flows to storage or to points of use. A start-up divert timer setting in the timer presets menu of the ECM-100 controls the duration of permeate divert each time the machine starts up.
23G-Series RO System 6.1 Level Controls Float switches pressurized storage tank switches or other level controls may be connected to the ECM-100’s tank level control inputs. To recognize the tank level status, the ECM-100 must be in the AUTO mode. A level control system with “one” input signal may be connected to the ECM-100 across terminals 17 and 18 of the main strip. Terminals 40 and 41 must be jumpered together in this case.
23G-Series RO System 6.2 pH Controller/Sensor (ECM-100-pH) A factory installed pH sensor can be connected to your ECM-100. A high/low pH alarm is included with the pH sensor and should be set at pH 7 and 4, respectively (unless special instructions or conditions indicate otherwise) to protect against excess or loss of buffer feed. If the high pH alarm deactivates the machine, the buffer tank and buffer pump must be checked to ensure that buffer is being fed properly, and that the pump is primed.
23G-Series RO System 6.3 Printer/Computer Interface The ECM-100 is designed to allow data downloads to a computer or a printer. The basic process of downloading the information to a printer or computer is the same. Data can be downloaded as individual lines of information (Current display), or large groups of information (Historical log).
23G-Series RO System To capture data from ECM-100 to a PC using HyperTerminal® Go to the windows application (START menu) and choose “Programs””Accessories””Communications””HyperTerminal” You will then need to choose a file name, i.e. “23G RO data” click OK You will then need to choose the connection, i.e. COMM 1, COMM 2 etc. click OK You will then be prompted to choose a BAUD rate. The baud rate on the computer should match the baud rate on the ECM-100 controller.

23G-Series RO System 7.2.1 Resetting the ECM-100 If exterior problems (such as power surges, lightening storm) have damaged the ECM-100. Power down (disconnect) to reset the ECM-100. A high quality inline surge protector suppressor is recommended to avoid related problems. 1. Press the ECM-100 OFF key to turn the machine OFF. 2. Disconnect the power to the ECM-100 (for single-phase machines, also disconnect power to the motor controls).
23G-Series RO System 6. Ensure the terminal board is firmly connected to the main board by gently pressing on the top of the strip, pushing it toward the main board. CAUTION: Do not apply too much pressure - you may damage the board. 7. Reconnect power and test for proper operation. For additional assistance contact your equipment supplier. 7.2.3 If sporadic, unexplained alarms occur, check the Relay Board Terminal Strip for good connections (Relay Board).
23G-Series RO System The ECM-100 calculates % rejection using the following equation: % Rejection = 1- Permeate Conductivity Feed Conductivity x 100 Since the % rejection is based on a ratio between the feed conductivity and the permeate conductivity, higher quality feed water may result in a low % rejection alarm. Higher recovery will typically lower the permeate rejection using the ECM- 100 calculations.
23G-Series RO System 7.2.5 Verifying the Temperature Circuitry of the Main Board 1. Turn the machine OFF. 2. Unplug the power cord for the ECM-100. 3. Disconnect the temperature sensor wires from terminal posts 23 and 24. 4. Cover the temperature sensor wires which were removed from terminal posts 23 and 24 with electrical tape. Secure these wires in a location that prevents contact with the main circuit board. 5. Install a 3 K ohm resistor between terminal posts 23 and 24. 6.
23G-Series RO System 7.2.6 Difficulty Calibrating Permeate Conductivity The integrity of the permeate conductivity circuitry on the main logic board can be verified by connecting a fixed resistor in place of the conductivity probe. 1. Turn the machine OFF. 2. Unplug the power cord for the ECM-100. 3. Disconnect the permeate conductivity wires from terminal posts 27 and 28. 4. Install a 5 or 10 K ohm resistor between terminal posts 27 and 28. 5.
23G-Series RO System V1 and V2 main logic boards and relay boards are interchangeable (i.e., you could have a V1 main logic board and a V2 relay board and vice versa). 23G machines built after 1997 contain Version 2 (V2) circuit boards. This new circuit board includes extra electronic components built into the circuit board. When ordering replacement parts identify whether you have V1 (machines built prior to 1997) or V2 (machines built after 1997). Contact your equipment supplier with questions.
23G-Series RO System 8.3 8. Rinse or blot away any remaining droplets of the pH solution and reinstall the pH sensor into the incoming waterline. 9. Generally this 2-point pH calibration procedure should be repeated on a bi-monthly basis. Some situations will require more frequent recalibration while others will require less. 10. If the probe does not seem to be responding, try soaking it in a 2.0 pH acid for 10 minutes. Repeat the calibration. 11.
