Bather Load; Filter Cleaning - Cal Spas F-1222 Owner's Manual

Using Bromine as a Sanitizer
Bromine is a very effective sanitizer that produces
low chemical odors. Unlike chlorine, it can break
down bacteria and other impurities to a safe level
with a low burn-out rate.
Use granulated sodium bromide to establish your
bromine base.
When you begin with fresh water, add 2 ounces of
granulated bromide. Open all of the jets and run the
spa at high speed with the cover open for at least
30 minutes.
Follow the maintenance schedule on page 40.

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.

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.
It is extremely important that you never run the spa without a filter. There is a possibility that
debris may be sucked into the plumbing through the filter well.
Set the spa in Hold Mode before you remove the filter. Hold Mode pauses all spa operations for 60
minutes for service functions like cleaning or replacing the filter. See page 15 for instructions on
using Hold Mode .
Cleaning the filter
1. Remove the filter by unscrewing it and pulling it up and out.

Shocking the Water
In addition to using a chemical sanitizer, you will
periodically need to shock the water. Shocking the
water helps remove burned-out chemicals, bacteria,
and other organic material from your spa's water
and improves your sanitizer's effectiveness.
Do not use chlorinating shock, which will damage
your spa's jets and pump seals. Only use an oxidizer
shock. It can be used with either chlorine or bromine
sanitizers.
Add one ounce of oxidizer shock once a week, after
heavy bather loads, or if water has a strong odor.
Spa must be running with all of the jets on high for
30 minutes with the cover open. If necessary, repeat
oxidizer shock in 30 minute intervals.
