7. Set Spa To Heat
To warm spa water to a comfortable temperature, follow
these steps:
The LCD display on the control panel displays the
actual temperature of the spa water. Press either the
COOLER or WARMER button once to display the “set”
temperature for 5 seconds. If you want the water to heat to a different
temperature, simply press COOLER or WARMER within 5
seconds. The set temperature increases or decreases by one degree
each time either buttons is pressed.
The heater will turn off 1 degree above set temperature and turn on 1
degree below set temperature.
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).
For North American spas powered by a service of 30 amps, turn
off jets pumps to operate heater. With a 40 amp or 50 amp, turn off
both jets pumps to operate heater. With a 60 amp, the heater will
operate with both jets pumps on.
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 degree above the
programmed “set temperature”, then turns off. The heater will
reactivate after the water cools to approximately 1 degree 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).
