J-400 Series
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 less than 60 amps, turn
off jets pump #1 and jets pump #2 to operate 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 1 degree above the
programmed “set temperature”, then turns off. The heater will reac-
tivate 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 injury! Always check water temperature carefully
before entering spa!
