ture 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 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.
• The time required for initial heat-up will vary depending on the start-
ing water temperature.
DANGER: Risk of injury, always check water temperature
carefully before entering spa!
