• The heater will turn off when the temperature corresponding to the
thermostat setting is achieved.
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.
• The time required for initial heat-up will vary depending on the start-
ing water temperature.
Decontamination Procedure (Steps 9-15)
Steps 9-15 pages below are only required when sanitizer levels are
unstable after performing steps 1-6 above. Disregard steps 9-15 below
if sanitizer levels remain stable at 3.0-4.0 ppm chlorine or 2.0-4.0 ppm
bromine after performing steps 1-6.

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 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.
• 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.
