Sundance Spas Export 680 Series Owner's Manual page 25

Important Heater Details:
• The maximum temperature for which the spa can be set is 40°C
(104°F) and the minimum is 18°C (65°F).
• 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°C (2°F) 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.

Check water temperature carefully before entering hot tub!
Excessive water temperature can cause burns, welts and
body temperature to rise, hyperthermia (over-heating).
