780 SERIES
Important Heater Details:
• The maximum temperature for which the spa can be set is
104°F (40°C) and the minimum is 65°F (18°C).
• For North American 2-pump spas powered by 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.
• For Export (50 Hz) 2-pump spas powered by a 20 amp
service, jet 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."
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:
Check water temperature carefully before entering hot tub!
!
Excessive water temperature can cause burns, welts and
body temperature to rise, hyperthermia (over-heating).
