Clear Water Plan

“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 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 prob-
lems, 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 recom-
mendations. 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 pe-
riodically 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 1.
out.
Place the dirty lter into a bucket of water deep enough to cover the lter. 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 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 aside3.
Soak the lter for a minimum of 24 hours.4.
Spray the lter 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 lter.6.
Reinstall the lter. Do not overtighten.7.
