Possible Cause
Possible Remedy
If pool has excessive salt or if salt is not properly mixed, system may eventually shut down and must be restarted by turning off the power swtich,
(located on the bottom of the unit), and turning it back on again.
If system shuts down due to excessive salt, a water sample should be taken to your pool/spa dealer for an accurate, (electronic), salt reading.
Once salt level exceeds 3,000 ppm, the CSS system automatically lowers power, therefore chlorine production.
If salt exceeds 4,000 ppm, system may shut down and will require a power restart. Dilute pool water to adjust.
If power indicator light does not come on when system is powered up:
Verify system switch is in the “On” position.
Check for water flow through the bypass, ensuring there are no kinks in the hoses.
Verify ozone optic indicator light is on.
If chlorine reading is low or non-existent:
Check for debris in cell.
Run system longer
Reset power switch
Perform “bucket test” to verify chlorine cell is working, by first turning off pool pump. Disconnect 3/4” hose from bypass exit. Screw supplied cap onto
exit point fitting. Turn pool pump on and fill a 5-gallon bucket with the water coming out of the 3/4” bypass hose. Turn pump off. Take a sample of the
water in the bucket. Dilute 10:1 with distilled water and test. Perform this test twice, once with the chlorine dial at 100% and again with the chlorine dial
at 20%. Remove cap and reconnect 3/4” hose to bypass exit point fitting before restarting pool pump.
If you still get no chlorine reading, contact a Prozone customer representative.
