Optional Cd Ozone Water Maintenance System; Error Conditions/Error Messages; Summer Logic - Jacuzzi J-315 Owner's Manual

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 Jacuzzi 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 cer-
tain materials in the spa. Damage caused by use of this chemi-
cal, or improper use of any chemicals, is not covered under the
spa's warranty.

12.3 Optional CD Ozone Water Maintenance System

If you have elected to have your spa equipped with the optional Jacuzzi
CD ozone water purification system you will find that your water stays
fresh and clear with significantly less chemical sanitizer usage. You will
also probably be able to go longer between complete spa drainings. The
CD ozone unit operates in conjunction with the circulation pump.

13.1 Summer Logic

When the actual spa water temperature reaches up to 2°F
(1°C) above the set temperature, the spa goes into "sum-
mer logic" causing the circulation pump and heater to turn off
automatically. This will avoid the addition of heated water to
the spa, which would eventually create an overheat condi-
tion. This setting is not user-programmable.
Note: The summer logic does not take effect until the spa water
temperature 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.
