“Bather Load” is the term used to describe the number of people using a spa, combined with the length of
usage, and the frequency of usage. All these factors have a great eect on the spa water. The higher the bather
load, the more chemicals need to be added and a longer filtration time will be needed.
Recommendations are designed for spas with average bather load (3 to 4 people, 15 minutes of usage,
three times a week at 100 degrees). If your bather load exceeds these guidelines, and you experience water
quality problems, increase the amount of filtration first, (go to the next higher filtration number) then if water
quality is still not adequate, consult the advice of your Cal Spas dealer for additional chemical or system
recommendations. Be sure to give them your bather load information.

The ozone generator releases ozone into the spa water. You will still need to test for chlorine or bromine and
occasionally replenish it to return the sanitizer level to the baseline.
For spas without a circulation pump, pump 1 will run at low speed and the ozonator will run during filtration.
The spa’s control system is factory-programmed with one filter cycle that will run in the evening when energy
rates are oen lower. The time and duration of the filter cycle can be set according to your needs. In addition, a
second filter cycle can be enabled. Filtration time may need to be increased with heavy bather load.
See instructions for setting filtration cycles on page 20.

Always make sure water diverter valves are turned all the way to the le or right and never le in the center
position during filtration cycles. When the diverter valve is in the center position, there is not enough suction
from the pump in order to inject ozone into the spa. The ozonator will generate ozone, but it will not be injected
into the water.
