150 ppm

cloudy water. Check alkalinity
pH and clean filter. Run filtration
system and ozone 24 hours.

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.
