    Depending on the feed water quality, it may be possible to operate the unit with a lower concen- trate flow rate, which would decrease operating costs. Refer to the printout from the Culligan® CAAP® (Computer Aided Application Program) software, which indicates maximum allowable recovery.
  • Page 27 Once all the desired flows are set, allow the system to run for approximately 30 minutes, and then record the following measurements using the units gauges (U) and your instruments (I): a. Feed Water Temperature, °F (I) b. Feed Water SDI (I) c.

    Accessories TDS Probe (Optional: Order Separately) An optional TDS probe (P/N 01021876) monitors the water quality in the system. If the total dissolved solids measured by the TDS probe exceeds the required quality level set by the DIP switches, the system will stop producing treated water. The probe is connected to the CP Plus board via an MT board (P/N 01022143): see Figure 23.

  • Page 34: Service And Maintenance

    Service and Maintenance Serial Numbers The Culligan M1 units have a serial number located directly behind the electronic controller on the side panel. Do not remove or destroy these serial number labels. They must be referenced if you require repairs or parts replacement under warranty.

  • Page 39 Sanitizing Modules The modules may need sanitizing if either of the following conditions exist: • The RO system is subject to biofouling and the operator wants to reduce the cleaning frequency. • The water treatment application limits the microbial count in the product water. CAUTION! The bottom of the tank must be higher than the pump on the RO unit to prevent cavita- tion of the pump when solution is drawn from the tank.
  • Page 40 Apply power to the unit, and then press the RUN NOW button. Slowly close the recirculation and drain valves until the system operating pressure increases to normal pressure. NOTE Increase the pressure no faster than 5 psi per second. Cat. No. 01022940 Culligan® M1 Series Reverse Osmosis...
  • Page 41 Allow the unit to run for at least 30 minutes. Check the product water until the pH for the concentrate and prod- uct remains stable for five (5) minutes and the TDS is greater than 95 percent rejection. Turn the unit power off. Connect the concentrate tubing from the membrane to the motor panel.

  • Page 43 Prepare the Equipment for Cleaning Turn the unit power off. Place the solution tank on the tank stand. Connect the tubing to the cleaning adapter then place the other end of the tubing at the bottom of the solution tank. NOTICE The tubing length should be as short as possible to prevent excessive pressure drop.
  • Page 44 The temperature of the chemical solution will rise as it is recirculated. If the temper- ature exceeds 95°F, turn the unit power off and allow the solution to cool to prevent damage to the RO elements. Cat. No. 01022940 Culligan® M1 Series Reverse Osmosis...
  • Page 45 Compare these values with the “new” and “now” values to determine if cleaning has been successful. If cleaning has not been successful, contact the service department at Culligan International Company for suggestions on alternate cleaning chemicals. If cleaning has been successful, note which chemicals were effective. Use the same chemical(s) when the unit is cleaned again.

    Appendix B Basic Principles Reverse Osmosis In order to understand reverse osmosis, we must first define osmosis. Osmosis is the passage of a liquid through a semi-permeable membrane. A semi-permeable membrane is a membrane which allows one component of a solution to pass through it and not the others.
