Insufficient water flow or air bubbles
This may happen temporarily if there is air in the
lines at initial startup. Check water level, pump
cavitation, air or blockages in plumbing, and all
valves & seals. Clean filters & strainers. Ensure
at least 25-30 GPM flow rate.
Verify correct orientation, cable is plugged in, 6-
12" of straight pipe before Flow Switch
Ensure O-Rings are clean and in good condition.
Threaded collars are cross-threaded or
pipes are misaligned
Inspect threads for damage, ensure that each
screws back on without resistance.
Real-Time Salinity and Cell
current read zero
Zero reading during normal rest cycle
No action is required. Will rise after rest cycle or
raising output
Incorrect voltage / loose cell connection
Have professional check wiring.
Incorrect Cell Version set
Verify Cell Version in Status Menu.
No Flow, Lo Salt, High Salt, or Cell Maint.
LED on
Cell frequently has mineral
buildup
This is due to imbalanced water chemistry
and a high Saturation Index
Ensure that your Saturation Index is at or near
zero, in order to avoid damage or premature
Cell failure. (page 8)
Cell never or rarely has mineral
buildup
Water may be corrosive due to imbalanced
water chemistry and a low Saturation Index
Ensure that your Saturation Index is at or near
zero, in order to avoid damage or premature
Cell failure. (page 8)
Water temperature is too hot or cold for
operation
Check operation of heater, or turn off until water
temp is above 65° and more sanitation is needed.
Clean Cell (see page 12).
