“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.
All versions of the Cal Spas Clear Water Plan 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.

Filter Cleaning
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.
Remove the filter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and 1.
out.
Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of Cal Spas “Liquid 2.
Filter Cleaner” 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.
Twist off the tablet tube and set it aside. 3.
Soak the filter for a minimum of 24 hours. 4.
Spray the filter with a water hose. Spray each pleat carefully. 5.
Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the filter. 6.
Reinstall the filter. Do not overtighten. 7.
About the Cal Pure UV Water Sanitizer
The Cal Pure system is installed at the factory and works 24 hours a day with the continuous filtration pump
during normal operation of the spa. There are no settings to adjust and is virtually maintenance-free. It
eradicates germs in the water that are resistant to chlorine-based chemicals using high intensity UV light.
Once a year the UV light needs to be replaced. This is not a user-serviceable item and must be performed
by a spa technician.
