Your new hot tub comes equipped with an electric heater.
Following the directions listed below will ensure the most
efficient operation:
NOTE: This method is only for hot tub usage under two
hours a week.
• Keep the hot tub’s operating temperature 5˚F below
the desired usage temperature when not in use. One
or two hours before use, set the temperature to the
desired temperature.
• If the hot tub usage exceeds two hours a week, the
set temperature should remain at the desired usage
temperature.
• The air venturis should be used sparingly. When open,
water temperature drops quite rapidly and can also
dissipate chemicals.
Allowing the water temperature to lower more than 10˚F
below the desired usage temperature and reheating it prior
to usage will cause the heater to operate longer than it
normally would maintaining the desired temperature. Doing
this will increase your operating cost and makes your heater
work more than necessary.
