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: With a 50 amp service, turn off one
of the jet pumps to operate heater. With a 30 amp service, turn
off both jet pumps to operate heater. With a 60 amp service, the
heater will operate with both jet 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).
