Problem Possible Cause Solution
No water running to
equipment.
Water supply is turned off. Turn on the water.
Water supply is blocked.
Prelter is plugged.
Clear blockage.
Change prelter.
Membrane cartridge is fouled. Replace membrane cartridge.
Incoming water line is crimped or
pinched off.
Check incoming line and verify no crimps in line. Remove any pinch points.
Running out of
optimized water
Operating pressure reduced Prelters need to be replaced.
Very cold feed water Feed water temperature too low, increase water temperature up to 80°F to
increase production with tempering valve or check if larger RO membrane or
tank can be added.
Valves are in incorrect positions Ensure the inlet valve and outlet valve on the RO processor are open. See hang
tag for normal operation. On the atmospheric tank, ensure the inlet valve is open
and the buffer tank outlet valve is open.
Atmospheric tank not working-
No power
See "repressurization pump does not turn on" page 23.
Demand exceeds system capacity Check RO permeate ow. Water temperatures of 48°F will reduce permeate
output by 50%. Inlet pressures of 30 psi will reduce permeate output by more
than 50% compared to 60 psi inlet. Consult with technical support if permeate
ow is too low. Determine if the demand is unusual or inconsistent, or resize
system with higher capacity membrane and/or tank.
Atmospheric tank -Low water
level- Atmospheric tank system
status yellow or ashing yellow
If system status is yellow, water will need to ll to minimum level. After water
rells tank above low level sensor, the status light will ash yellow and the
repressurization pump will start after 5 minute delay.
Atmospheric tank-
Repressurization pump running,
but not pumping water
Pump is air locked. Remove outlet pressure from pump by draining outlet to
reprime pump.
Reverse osmosis membrane
fouled
Replace reverse osmosis membrane every 12-24 months. See "Short membrane
life" page 23 for additional information.
Low feed water pressure Install optional feed water pressure booster pump to get pressure up to 60-80
psi. Check outlet pressure of existing booster pump if already installed.
Tank overowing
High level sensor and tank oat
shut-off failing
Check sensor connection, verify if connected to wire harness. Replace if needed.
Open tank cover and check oat shut-off by raising oat; replace if necessary.
Poor quality
optimized water
Blend valve out of adjustment Follow steps on page 17 to adjust blending valve.
Low TDS rejection
<75%
Inlet and outlet valve not in
normal operation
See Hang tag for normal operation. Measure reject ow rate and compare to
reject ow restrictor chart on page 13. Replace prelter, capillary ow control and
RO membrane as needed. When moving inlet and outlet handles from bypass to
service positions, you may detect a pressure imbalance that prevents the outlet
handle from reaching full nal position. Correcting this issue by turning the valve
outlet or inlet handles open and closed again, will help equalize pressure to allow
inlet and outlet valves handles to fully engage to the service position.
Blend valve out of adjustment Follow steps on page 17 to adjust blending valve.
Membrane failure Measure TDS out of permeate sample port. Measure reject ow rate. Replace
prelter and RO membrane as needed. Check to see if the capillary ow control is
plugged. Replace capillary ow control as needed.
Nonblended
optimized water
<25 ppm
Mineral feed cartridge exhausted Replace mineral feed cartridge with 4CM for 375 system, 7CM for 650 systems
every 6–2 months.
