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 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 either buttons is pressed.
• The heater will turn off 1 degree above set temperature and turn on 1
degree below set temperature.
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).
• For North American spas powered by a service of 30 amps, turn
off jets pumps to operate heater. With a 40 amp or 50 amp, turn off
both jets pumps to operate heater. With a 60 amp, the heater will
operate with both jets pumps on.
• 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 1 degree above the
programmed “set temperature”, then turns off. The heater will
reactivate after the water cools to approximately 1 degree 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
operating costs.
• The time required for initial heat-up will vary depending on the
starting water temperature.
DANGER: RISK OF PERSONAL INJURY.
Check water temperature carefully before entering hot tub!
Excessive water temperature can cause burns, welts and body
temperature to rise, hyperthermia (over-heating).
