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.
CAUTION: Do not use chlorine tablets (Trichlor) in your spa. This
chemical can have an extremely corrosive effect on certain mate-
rials in the spa. Damage caused by use of this chemical, or improp-
er use of any chemicals, is not covered under the spa's warranty.
12.3 Optional UV or CD Ozone Water Maintenance System
If you have elected to have your spa equipped with the optional UV or CD
Ozone water purification system you will find that your water stays fresh
and clear with significantly less chemical sanitizer usage. You will also prob-
ably be able to go longer between complete spa drainings. The UV or CD
ozone unit operates in conjunction with the circulation pump.
13.0 Error Conditions / Error Messages13.1 Summer Logic
When the actual spa water temperature reaches up to 2 °F
(1 °C) above the set temperature, the spa goes into “summer
logic.” The circulation pump will turn off automatically to
avoid adding additional heat to the water, eventually creating
an overheat condition. This setting is not user-programma-
ble.
Note: The summer logic does not take effect until the spa water tempera-
ture reaches 95 °F (35 °C). This condition is more likely in excessively hot
weather. Remember, the spa’s ability to cool is directly affected by the
ambient temperature. An excessively hot ambient temperature may prevent
the spa from cooling down because it’s fully insulated construction is
designed to retain heat and to minimize operating costs. Page 27
