Automatic Functions
Clean-up Cycle
The Clean-up Cycle is a feature that automatically turns on a pump (or the blower) 30 minutes
after it was last turned off or timed out. The pump will run for approximately 30 seconds to move
water through the system to help maintain clear water.
Purge Cycle
The Purge Cycle is intended to keep the spa as clean as possible by flushing all jet lines every
12 hours. All pumps will turn on for 2-3 minutes. In Economy mode, the purge cycle occurs at the
beginning of each heating cycle.
Freeze Protection
Freeze Protection is activated if the temperature sensors in the heater detect a temperature drop
to 44°F. All pumps (including the blower) activate automatically and remain on until 4 minutes af-
ter the sensors detect that the spa temperature has risen to 45°F or higher. During this time “ICE”
will be displayed and no button presses will be recognized until the spa water has reached 45°F.
Note:
• It is imperative that the spa remain on. Do not drain the spa or cut the power. If the spa must
be drained, the we recommend that you winterize the spa, page 38. It must be allowed to
heat.
• To assist with water circulation you can use a submersible pump. To assist with water cir-
culation you can use a submersible pump. Place the pump in the footwell of the spa, facing
upwards. (Do not attach a water hose to the pump.) This creates a waterfall and keeps the
water moving. Leave the pump running until the spa is repaired. Keep the spa covered and
all panels on the unit. The submersible pump will also generate heat and protect the spa for a
period of time.
Circulation Pump
The Circulation Pump will run 24 hours a day, 7 days a week to efficiently and effectively filter
your spa water. However, if the spa temperature exceeds the set-point by 3°F the circulation
pump will automatically turn off. It will only turn back on during the preset filtration cycles or after
the water temperature is within or below 3°F of the set-point. Any time the circulation pump is
running, your spa will be filtering water (unless your filters are too dirty to permit water to pass
through them).
Power-Up Sequence
When power is first applied to the spa an automatic Priming Mode will begin and the LCD screen
will display “Pr.” This mode last up to 4 minutes and once complete the spa will begin to heat until
the set temperature is reached.
Note: During the priming mode if either the Warm or Cool button is pressed the spa will exit the
Priming Mode early.
