Ozonator
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 ltration.
For spas with a circulation pump, the ozonator will run with the circulation pump.
The spa’s control system is factory-programmed with one lter cycle that will run in the evening when energy
rates are often lower. The time and duration of the lter cycle can be set according to your needs. In addition,
a second lter cycle can be enabled. Filtration time may need to be increased with heavy bather load.
See instructions for setting ltration cycles on page 11.
Bather Load
Filter Cleaning
“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 effect on the spa water. The higher the bather
load, the more chemicals need to 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 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 lter is the part of your spa that removes the debris from the water and needs to be cleaned on a regular
basis to maximize your spa’s ltering performance and heating efciency.
In addition to spraying off the lter weekly to remove surface debris, your lter should be deep cleaned
periodically to dissolve scale and particles that get lodged deep within the lter bers and impede the ltration
process. Even if the lter looks clean, scale and particles can clog the bers and prevent water from owing
through the lter resulting in the most common spa problem—no heat, caused by a dirty lter.
We recommend you clean your lter once a month and replace it once a year or as necessary.
It is extremely important that you never run the spa without a lter. There is a possibility that
debris may be sucked into the plumbing through the lter well.
Cleaning the lter
Remove the lter by unscrewing it and pulling it up and out.
1.
Place the dirty lter into a bucket of water deep enough to cover the lter. Add 8 oz of liquid lter cleaner 2.
to the bucket of water.
Note: It is a good idea to keep a spare lter to use in the spa while the dirty lter is being deep cleaned.
This way, you can rotate the lters and both will last longer.
Soak the lter for a minimum of 24 hours.3.
Spray the lter with a water hose. Spray each pleat carefully.4.
Reinstall the lter. Do not overtighten.5.
