6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading of no less than 1.0 ppm free
chlorine or 2.0 ppm bromine. To ensure healthy water conditions,
always maintain a constant sanitizer reading within the levels
recommended on the inside cover of this manual.
7. Set Spa To Heat
To warm spa water to a comfortable temperature, follow these
steps:
• The display on the control panel displays the actual
temperature of the spa water. Tap or to increase or decrease
the water temperature in 1°F (0.5°C) increments.
• The heater will turn off 1°F (0.5°C) above set temperature and turn
on 2°F (1°C) below set temperature.
Note: The temperature range for the spa is 65 to 104°F (18.33 to 40°C).
To activate the Extended Temperature feature that allows the spa to
reach 106°F (41°C), page 76.
Important Heater Details:
• The maximum temperature for which the spa can be set is 104°F
(40°C) and the minimum is 80°F (27°C).
• Refer to section 7.0 for specic heater functions.
• 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 1°F (0.5°C) above
the programmed “set temperature,” then turns off. The heater will
reactivate after the water cools to approximately 2°F (1°C) 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: RISK OF PERSONAL INJURY.
Check water temperature carefully before entering hot tub!
Excessive water temperature can cause burns, welts and
body temperature to rise, hyperthermia (over-heating).
