Turn the heater on some time (in hours) into the future
to a set temperature. The heating system will start after
12 hours, and continuously heat until the water reaches
104°F/40°C and then hold at that temperature. When the
spa water temperature drops 1.8-3.6°F (1-2°C) below the
set temperature the heating system will restart. When the
fl ame icon on the display is red, the heating system is
activated. When the fl ame icon turns green, the water is
at the set temperature. The heating system is at rest and
the fi ltration system will continue working nonstop.
Freeze Protection:
the spa heater is programed to automatically heat the water if the water
temperature falls below 39°F (4°C). While the spa should be stored during the winter months,
the system will protect the internal components in the event of occasional freezing temperatures.
The spa must be plugged in and the GFCI/RCD reset. The system will engage the fi lter pump
along with the heater and will operate both until the water reaches 50°F (10°C).
If extended freezing weather is expected, please disassemble the spa and store it during winter
according to the storage instructions.
Once the self-heating program is triggered, it cannot be switched off on the control panel until
the water temperature has reached at least 41°F (5°C), unless it is unplugged.
