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” (page 45) or has been sitting with-
out power for an extended period.

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 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.
• To access the overtemp feature refer to Section 10.3, page 28.
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 2° below the set temperature.
