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.
The red LED not lit
on ozone generator
No power to the ozonator
Check the electrical connections and
then the fuse
