Jacuzzi dealer. See Section 13.0 “Water Quality Maintenance” (page
43) for general guidance.

6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading of no less than 1.0 ppm free chlorine
or 2.0 ppm bromine. To ensure healthy water conditions, always maintain
a constant sanitizer reading within the levels recommended on the inside
cover of this manual. If sanitizer levels cannot be stabilized, perform the
decontamination procedure steps 9-15 on the following page.
Note: The “decontamination procedure” steps 9-16 should also be used
after the spa has been “Winterized” (Section 12.8, page 42) 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 LED display on the control panel displays the actual
temperature of the spa water. Press either the COOLER ( ) or
WARMER ( ) button once to display the “set” temperature for 5
seconds. If you want the water to heat to a different temperature,
simply press COOLER ( ) or WARMER ( ) within 5 seconds.
The set temperature increases or decreases by one degree each
time one of these buttons is pressed.
• The heater will turn off when the temperature corresponding to the
thermostat setting is achieved.
Important Heater Details:
• The maximum water temperature setting for your spa is 104°F
(40°C) and the minimum setting is 65°F (18°C).
• For North American spas connected to a 40 amp service, jets pump
#1 and jets pump #2 must be turned off to operate the heater.
• For Export spas connected to a 20 amp service, jets pump #1 and
jets pump #2 must be turned off to operate the heater.
• 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 the programmed “set
temperature,” then turns off. The heater will reactivate after the
water cools to approximately 1.5° below the set temperature.
