Your new spa comes equipped with an electric heater.
Following the directions listed below will ensure the
most efcient operation:
NOTE: This method is only for spa usage under two
hours a week.
• Keep the spa’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 spa 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.
