5. Add Start-Up Chemicals
Add the spa water chemicals as recommended by your authorized
Sundance dealer. See Section titled “Water Quality Maintenance”
(page 34) for general guidance.
6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading between 3.0-4.0 ppm chlorine
or 2.0-4.0 ppm bromine. To ensure healthy water conditions, always
maintain a constant sanitizer reading within the levels recommended
by the Association of Pool And Spa Professionals/USA printed on the
inside cover of this manual. If sanitizer levels cannot be stabilized,
perform the decontamination procedure steps 9-15 on the following
page.
Note: The “decontamination procedure” steps 9-15 should also be used
after the spa has been “Winterized” (Section 11.7, page 33) or has been
sitting without power for an extended period.
7. Set Spa To Heat
To warm spa water to a comfortable temperature, follow
these steps:
•
The LED 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 one of these buttons is pressed.
• The heater will turn off when the temperature corresponding to
the thermostat setting is achieved.
Important Heater Details:
• The maximum temperature for which the spa can be set is 104°F
(40°C) and the minimum is 65°F (18°C).
• For North American (60 Hz) 2-pump spas powered by a 40 amp
service, jets pump #1 must be set to low speed and jets pump #2
must be turned off to operate the heater.
• For Export (50 Hz) 2-pump spas powered by a 20 amp service,
jet pump #1 must be set to low speed and jets pump #2 must be
turned off to operate the heater.
• 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 the programmed “set
temperature”, then turns off. The heater will reactivate after the
water cools to approximately 1.5° below the “set temperature.”
