Your new Cal Spa comes equipped with an electric heater. Following the directions listed below will ensure
the most efcient 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 tem-
perature. Doing this will increase your operating cost and makes your heater work more than necessary.
