5. Too much suction 5A. Adjust the jets to reduce suction

6. Dirty, loose, cracked filter 6A. Check/replace filter as needed

7. Metals or minerals in water 7A. Ozone may react with metals/minerals

in the water (this is common when new

water is added) causing cloudy water.

Check alkalinity, pH, and clean filter.

Run filtration system and ozone for 24

hours and clean filter.

SYMPTOM: Pump loses prime when system is off

PROBABLE CAUSE CORRECTIVE ACTION

1. No flapper valve in pump 1A. Add flapper valve

strainer

SYMPTOM: System on/off – water backing into ozonator

When your system is in its “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 ozone chip or the ozone lamp, the oxygen in the air is converted to

ozone. This ozonated air is introduced to the water via the venturi on your

return line.

When the system is in its “off” cycle water tends to flow back in the

tubing towards the ozonator. Therefore, mounting your ozone unit as high as

possible in relation to the spa water level is important. There is also a one-

way check valve provided to prevent the back flow of water from reaching the

ozonator. As a secondary precaution, a Hartford loop in the tubing, also

hanging above water level, will help prevent water damage to the ozonator

(see pg. 6, Fig. 2).
