5.   Add Start-Up Chemicals
  Add the spa water chemicals as recommended by your authorized 
Jacuzzi dealer. See Section 13.0 “Water Quality Maintenance” (page 
39) for general guidance.
WARNING:  RISK OF POISONING OR DEATH.
Never leave chemicals opened and accessible to anyone. 
Use chemicals according to the vendors instructions. Always 
store chemicals in a safe and/or locked location. Keep away 
from and out of reach of children.

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 12.7, page 38) 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 America spas connected to a 40 amp service, jets pump 
#1 must be set to low speed and jets pump #2 must be turned off to 
operate the heater.
•  For Export spas connected to a 20 amp service, jets pump #1 must 
be set to low speed 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.
