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 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.
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.
Ozonator
The ozone generator releases ozone into the spa water. You will still need to test for chlorine or bromine and
occasionally replenish it to return the sanitizer level to the baseline.
Set the spa’s filtration time for “F4” (described on
page 14 and
page 17
. This activates the ozonator and
produces the ozone gas. Note: Filtration time may need to be increased with heavy bather load.
“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.
