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.

13.0 Error Conditions/Error Messages

Your spa has a self-diagnostic control system. The system will
automatically display the following if a problem is detected.

13.1 Summer Logic (Spas with Circulation Pump Option)

When the actual spa water temperature reaches up to 2°F
(1°C) above the set temperature, the spa goes into "summer
logic." The 24-hour circulation pump will turn off automatically
to avoid adding additional heat to the water, eventually creat-
ing an overheat condition. This setting is not user-program-
mable.
Note: The summer logic does not take effect until the spa water temper-
ature 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 construc-
tion is designed to retain heat and to minimize operating costs.

13.2 Panel Displays COL

Cool Condition - Temperature has dropped 20°F (11°C)
below the current set temperature. Jets pump 1 and the
heater have been activated to bring the temperature to with-
in 15°F (8°C) of the set temperature. No corrective action is required!
Note: this condition is common during first time fillups or during refills
since tap water is often very cold.

13.3 Panel Displays ICE

Freeze Protection - A potential freeze condition has been
detected. No action is required. The pump and heater will
operate to circulate and warm water through the plumbing
until spa is out of danger. See "Winterizing" (page 28).
