Filter Cleaning; Bather Load - Cal Spas Inground Spas Owner's Manual

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 pe-
riodically 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.
1. Remove the filter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and
out.
2. Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of Cal Spas "Liquid
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.
3. Twist off the tablet tube and set it aside
4. Soak the filter for a minimum of 24 hours.
5. Spray the filter with a water hose. Spray each pleat carefully.
6. Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the filter.
7. Reinstall the filter. Do not overtighten.

Bather Load

"Bather Load" is the term used to describe the num-
ber of people using a spa, combined with the length
of usage, and the frequency of usage. All these fac-
tors have a great effect on the spa water. The higher
the bather load, the more chemicals need to be add-
ed 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
2009 Inground Spas
LTR20091002, Rev. B
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 prob-
lems, 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 recom-
mendations. Be sure to give them your bather load
information.
