Freeze Protection
If the temperature sensors detect a drop to 44°F
within the heater, the pump automatically activates
to provide freeze protection. The equipment stays
on until four minutes after the sensors detect that
the spa temperature has risen to 45°F or higher.
In colder climates, an optional additional freeze
sensor may be added to protect against freeze
conditions that may not be sensed by the standard
sensors. Auxiliary freeze sensor protection acts
similarly except with the temperature thresholds
determined by the switch and without a four-
minute delay in turnoff.
Light
Press the Light button to turn on the
light. Press it once again to turn the light
off. All optional lighting such as the control
panel light and cabinet perimeter lighting
is controlled by the Light button and will
turn on and off with the spa light.
Automatic Time outs
These features will automatically turn themselves
off during periods of continuous use:
Low speed pump *
High speed pumps
Optional circulation pump
Optional turbo
Spa light
* One pump systems only
Electrical Power Efficiency
Your new spa comes equipped with an electric heater.
Following the directions listed below will ensure the
most efficient 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.

Setting Filtration Cycles
Your spa is programmed to filter twice a day. The
first cycle will begin 6 minutes after the spa is turned
on and the second cycle 12 hours later. The factory
has programmed the cycle to last for 2 hours but
this can be switched to your preference.
To set time the filtration cycle begins, turn off the
power to the spa at the time of day you would
like one of the filtration cycles to begin then turn
back on after 30 seconds. When power has been
restored, press the Temp UP or the Temp DOWN
button, followed by the Jets button. Press Temp
UP or Temp DOWN again to change the filtering
cycle duration.
The filtration cycles and their displays are as
shown:
One pump systems
Two or three pump systems
After 4 hours
After 15 minutes
After 15 minutes
After 15 minutes
After 4 hours
•
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.
