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 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 filter 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 filtering performance and heating efficiency.
In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned
periodically to dissolve scale and particles that get lodged deep within the filter fibers and impede the filtration
process. Even if the filter looks clean, scale and particles can clog the fibers and prevent water from flowing
through the filter resulting in the most common spa problem—no heat, caused by a dirty filter.
We recommend you clean your filter once a month and replace it once a year or as necessary.
It is extremely important that you never run the spa without a filter. There is a possibility that
debris may be sucked into the plumbing through the filter well.
Set the spa in Hold Mode before you remove the filter. Hold Mode pauses all spa operations for
60 minutes for service functions like cleaning or replacing the filter. See
page 19 or page 27 for
instructions on using Hold Mode .
Cleaning the filter
Remove the filter by unscrewing it and pulling it up and out.
1.
Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of liquid filter cleaner
2.
to the bucket of water.
Note:
It is a good idea to keep a spare filter to use in the spa while the dirty filter is being deep cleaned.
This way, you can rotate the filters and both will last longer.
Soak the filter for a minimum of 24 hours.
3.
Spray the filter with a water hose. Spray each pleat carefully.
4.
Reinstall the filter. Do not overtighten.
