Clear Water Plan

“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.
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 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.

Filter Cleaning
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 efciency.
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.
Remove the lter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and 4.
out.
Place the dirty lter into a bucket of water deep enough to cover the lter. Add 8 oz of Cal Spas “Liquid 5.
Filter Cleaner” 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.
Twist off the tablet tube and set it aside6.
Soak the lter for a minimum of 24 hours.7.
Spray the lter with a water hose. Spray each pleat carefully.8.
Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the lter.9.
Reinstall the lter. Do not overtighten.10.
