12.0 Water Quality Maintenance

To decrease the risk of contracting a waterborne illness (e.g. an infection,
bacteria or virus) and/or respiratory ailments, maintain water quality within
specified limits. This will enhance your enjoyment and prolong the life of
the hot tub's equipment. Doing so requires regular attention because the
water chemistry involved is a balance of several factors. Procrastination in
regard to water maintenance will result in poor and potentially unhealthful
conditions for soaking and even damage to your hot tub investment. For
specific guidance on maintaining water quality, consult your Authorized
Sundance Spas dealer who can recommend appropriate chemical
products for sanitizing and maintaining your hot tub.
WARNING:
!
WILL:
• Increase risk of contracting a waterborne illness (e.g. an
infection bacteria or virus) and/or respiratory ailments.
• Damage the equipment, components and spa shell, which
are not covered under the hot tub's warranty.
CAUTION: Never store hot tub chemicals inside the hot tub's equip-
ment bay. The equipment bay may reach elevated temperatures,
this is where high voltage electronic devices are located. This area
is not intended for storage of any kind.

pH Control

pH is a measure of relative acidity or alkalinity of water and is measured
on a scale of 0 to 14. The midpoint of 7 is said to be neutral, above which
is alkaline and below which is acidic. In spa water, it is very important to
maintain a slightly alkaline condition of 7.4 to 7.6 pH. Problems become
proportionately severe the further outside of this range the water gets.
A low pH will be corrosive to metals in the spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling). In addition,
the ability of the sanitation agents to keep the spa clean is severely
affected as the pH moves beyond the ideal range. That is why almost all
spa water test kits contain a measure for pH as well as sanitizer.
12.2

Sanitizing

To destroy bacteria and organic compounds in the spa water, a sanitizer
must be used regularly. Chlorine and bromine are the two most popular
sanitizers used to date. Many other additives are available for your spa.
Some are necessary to compensate for out-of-balance water; some aid
in cosmetic water treatment and others simply alter the feel or smell of
the water. Your authorized Sundance dealer can advise you on the use of
these additives. When adding spa shock (chlorine or non-chlorine) or pH
balancing chemicals activate the jets pump(s) and leave the spa cover
open for a minimum of 20 minutes. By doing this you will allow excessive
chemical vapors to exit the spa, protecting pillows and plastic knobs from
chemical attack.
Note: SunPurity brominator cannot be used with the 680 Series.
