5. Add Start-Up Chemicals
Add the spa water chemicals as recommended by your authorized
Jacuzzi spa dealer. See section titled “Water Quality Maintenance”
(page 69) for general guidance.
6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading between 3.0-4.0 ppm chlorine
or 2.0-4.0 ppm bromine. To ensure healthy water conditions, always
maintain a constant sanitizer reading within the levels recommended
by the Association of Pool And Spa Professionals/USA printed on the
inside cover of this manual. If sanitizer levels cannot be stabilized,
perform the Decontamination Procedures on the following page.
Note: The “Decontamination Procedure” should also be used after
the spa has been “Winterized” (sec. 13.7, page 68) or has been sitting
without power for an extended period.
7. Set Spa To Heat
To warm spa water to a comfortable
temperature, follow these steps:
The LCD display on the control panel •
displays the actual temperature of
the spa water. Press either the UP or
DOWN button on the Navigational Quad Keypad to increase or
decrease the water temperature by 1 degree.
The heater will• turn off 1 degree above set temperature and turn
on 1 degree below set temperature.
Important Heater Details:
The maximum temperature for which the spa can be set is 104 °F •
(40 °C) and the minimum is 80°F (27°C).
For North American spas: With a 30 amp service, turn off one •
of the jet pumps to operate heater. With a 50 amp service, turn
off both jet pumps to operate heater. With a 60 amp service, the
heater will operate with both jet pumps on.
Setting the thermostat at maximum will not accelerate the heating •
process. This will only result in a higher ultimate temperature.
The heater operates until the water reaches • 1 degree above the
programmed “set temperature”, then turns off. The heater will
reactivate after the water cools to approximately 1 degree below
the “set temperature.”
8. Place Cover On Spa
Keeping the insulating cover in place anytime the spa is not in •
use will reduce the time required for heating, thereby minimizing
operating costs.
The ti• me required for initial heat-up will vary depending on the
starting water temperature.
