Ozone troubleshooting guide

Posted by on 5/18/2023 to Chemical

When your spa is in it's "on" cycle a suction of air is being pulled through the tubing from the ozonator to the return line. As the air passes by the UV bulb or chip, the oxygen in the air is converted to ozone. This ozonated air is introduced to the water via an action known as "Venturi". When your spa is in it's "off" cycle water tends to flow back in the tubing towards the ozonator. Therefore, installing the provided check valve and a "Hartford Loop" (see illustrations above) will help prevent this from happening.

Ozone is introduced into the water via the low speed (filter) mode. It is recommended that it runs on a 24 hour cycle, although, it can operate on the timer mode as well. You may have to keep a chlorine or bromine reserve when operating in this mode. The 24 hour cycle mode will not only cut back your chlorine or bromine use, but may replace it all together. It is recommended you use a Non-Chlorine Shock or a Mineral Cartridge such as Nature2 (not bromine compatible) or The Frog (bromine compatible). These three combined will keep your water sanitized and crystal clear.

Problem	Corrective action
No blue light glowing from ozone unit.	Cord or power not connected Breaker or GFCI tripped -Make sure water has not flooded ozonator Defective bulb, transformer or chip REPLACE OZONATOR
Flickering blue light	Incorrect voltage supply to ozonator -Confirm voltage at power supply.
No bubbles from ozone jet	Air control leaks Open or leaking air control valve. Check air control cap O-ring, replace if necessary -Relates to air control (Venturi) installations only. No Suction from tube connected to the ozonator Check for dirty filter (remove and run spa to see if it makes any difference) Make sure all adjustable jets are open completely Check for debris in jets Check ozone supply check valve (make sure it is installed correctly) Make sure tubing is not pinched
Cloudy Water	Unit operation time too short (minimum of 6 hours is recommended) Water chemistry out of balance Adjust Alkalinity between 80 -150 PPM Adjust pH between 7.2 - 7.6 Adjust Calcium Hardness between 100 - 250 PPM (acrylic finishes) Clean or replace the filter Shock the water with a non-chlorine shock and add a Mineral Purifier Nature 2 (not bromine compatible) or The Frog (bromine compatible).

Ozonators and injectors

IMPORTANT: When selecting an ozonator please be sure to check the voltage from where the ozonator will be receiving it's power.

Do not assume that because 220 volts is supplying the equipment that the ozonator operates at 220 volts.

Over-voltage or under voltage will void the warranty!
