Remedy
Replace cartridge(s).
Replace MR-600F RO Membrane Cartridge.
Check/repair booster pump and inlet line.
Refer to Problem 1.
Verify system output. If output is within specification, increase output if applicable.
Refer to Problem 1.
Replace MR-600F RO Membrane Cartridge.
Increase tubing/piping diameter. Refer to "System Installation" section for recommendations.
Replace prefiltration cartridge(s).
Check/correct any restrictions in drain line tubing. Make sure to allow for an air gap at the drain.
Disconnect reject line at quick-connect fitting and inspect for obstruction or damage. Remove
obstruction. Replace if required.
Check/repair booster pump and inlet line.
Check electrical connector engagement with pressure transducer.
Check for restriction/blockage in permeate line causing abnormally high pressure. Relieve
pressure in permeate line and correct restriction/blockage condition.
Measure RO permeate flow and TDS, then compare to previously recorded values or system
specifications. High permeate flow and/or poor TDS reduction indicates excessive passage of
water around or within the RO cartridge. Remove the RO cartridge and check the integrity of all
three (3) o-ring seals and correct as needed. If seals appear OK, replace the RO cartridge. After
making the repairs, press any key on controller to clear the fault, then recheck RO permeate
flows and TDS, then compare to previously recorded value or system specifications. If the fault
reappears after returning to normal operation, replace controller and/or pressure transducer or
