  • Page 3: Introduction

    6. 15-gallon atmospheric Storage Tank. 7. Constant pressure product water Re-pressurization Pump. The MRS-200 contains all the necessary piping, valves and fittings pre-assembled onto a floor- standing rack. Lengths of ¼” and 3/8” tubing are provided for connecting to the wastewater/drain and sample/flushing lines.

  • Page 4: System Installation

    Optional inlet booster pumps are available to increase supply water pressure and system production. System Installation 1. Locate the MRS-200 system in an area that is convenient to the inlet water supply and drain facilities, with access routing...
  • Page 5 3. Refer to Figure 2 for a view of the complete assembly, with a description of major components and connection points. Place the main unit on the shelf, positioning the cartridge heads directly over the cutout area. Insert a cable tie into one of the holes in the baseplate and through the wire “slats”...
  • Page 6 The booster pump increases the incoming pressure by approximately 45 PSI. Do not install the inlet booster pump on water supplies with a dynamic pressure in excess of 75 PSI. Do not connect the MRS-200 system after any water filtration system, unless specifically provided for use with the MRS-200.
  • Page 7 If a booster pump is required, refer to Figure 4. Assemble a male elbow fitting to the pump inlet and a male connector fitting to the pump outlet. Attach the pump to the mounting plate with the hardware provided. Attach the pump with mounting plate to the backplate with the hardware provided.
  • Page 8 ¾” ID minimum. Connect the appropriate size and type of tubing/piping and associated fittings to the RO product outlet on the MRS-200 system and route the lines to the equipment being serviced (i.e.; espresso, coffee, etc.).
  • Page 9 Figure 6 Figure 8 Figure 7 10. Attach short length’s of ¼” and 3/8” OD tubing to the TO flush valve and product water 3- way sample valve connection located near the TO flush valve. 11. Refer to figure 9. Locate the 10-foot power cord attached to the control enclosure. Connect the fork connectors on this cord to the terminals on the 24 VAC transformer.

  • Page 10: Cartridge Installation And Activation

    Cartridge Installation and Activation 1. Remove the outer shrink-wrap and protective closure from the pre-filter, TO and RO cartridges. 2. Remove the sump from the pre-filter housing. Install the pre-filter into the sump. Locate the O-ring in the small parts pack. Lightly lubricate this O-ring with a food grade lubricant and install it into the groove in the sump.
  • Page 11 Hint: Use the TO flush valve for a source of water to fill the storage tank after the level switch stops the flow of water. 3. The storage tank requires complete draining at this time. This can be accomplished one of two ways, based on what steps were done in step 1 above.

  • Page 12: Adjusting The Recovery

    40% recovery. Note: Problem water applications such as high TDS (TDS > 1000) or high silt (SDI > 3) will require a lower recovery of 10-20% to prevent membrane fouling. Consult Everpure Technical Service for assistance.

  • Page 14: Operation

    A double blink indicates calendar limits have been reached. Maintenance The MRS-200 Reverse Osmosis system requires very little maintenance. Regular cartridge change-out is the only normal requirement, and a very important one. The cartridge usage monitor provides visual indications once 80% and 100% of selected volume and calendar ranges are reached.
  • Page 15 9. Slowly open the inlet shut-off valve. 10. Connect the 24 VAC transformer to the 115-Volt receptacle. 11. Demand water from one of the pieces of equipment serviced by the MRS-200 to drain down the storage to the point the solenoid energizes and the system begins make RO water.

  • Page 16: Performance Monitoring

    1. Obtain an outlet water sample and TDS measurement as described above. 2. Obtain an inlet water sample in the same manner as above, but from the inlet water source to the MRS-200 system. 3. Using your TDS/conductivity tester, measure and record the TDS/conductivity value of the inlet water sample.

  • Page 17: Performance Log

    100 = 92% TDS reduction 600 ppm This means that the MRS-200 system has removed 92% of the dissolved solids from the inlet water. The RO cartridge should be changed every 1 to 1-1/2 years or when the percent reduction falls below 90%.
