Problem
Possible Cause
What to Do
Cloudy water
condition even
though the unit
appears to be
operating properly
Unit and pump not operating
long enough
Increase operating time (min. 6
hours is recommended)
Total alkalinity not correct
Adjust total alkalinity between 8 and
150 ppm
pH not correctly balanced
Check for proper pH between 7.2
and 7.6
Not enough suction
Clear any obstruction in the water
lines or return fitting
Dirty, loose or cracked filter
Check/replace spa filter as needed
Metals or minerals in the
water
Ozone may react with metals/
minerals in the water causing
cloudy water. Check alkalinity
pH and clean filter. Run filtration
system and ozone 24 hours.
System won’t turn
on/off
Water backing into the unit
Mounting the 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 it. As a secondary
precaution, a Hartford Loop in
the tubing, also hanging above
water level, will help prevent water
damage to the unit.
