(page 46) 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 
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 9-15 should 
also be used after the spa has been “Winterized” (sec. 12.7, page 
45) 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 tempera-
ture of the spa water. Press either the COOLER   
or WARMER   button once to display the “set” tem-
perature 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 but-
tons is pressed.
•   The heater will turn off when the temperature corresponding to the 
thermostat setting is achieved.  
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). 
 
•   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.”
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 operat-
ing costs.
