“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 the be added and a longer ltration 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 ltration rst, (go to the next higher ltration number) then if wa-
ter 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/bromine and
occasionally replenish it to return the sanitizer level back to baseline. For spas without a circulation pump,
“Pump 1” will run at low speed and the ozonator will run during ltration.
The spa’s control system is factory programmed with one lter cycle that will run in the evening, aligning
with lower energy rates in that time slot. The time and duration of the lter cycle can be set according to
your needs. In addition, a second lter cycles can be enabled. Filtration time may need to be increased with
a heavy bather load.
Make sure water diverter valves are turned all the way to the left or right, and never left in the center
position during ltration cycles. When the diverter valve is in the center potion, there is not enough suction
from the pump in order to inject ozone into the spa. The ozonator will generate ozone, but it would not be
injected into the water eectively.
