INITIAL START-UP
Before applying voltage to power-up your hot tub, it is very
important that you understand the sequence of events that
occur when the system is activated in order that the pumps
can be primed efficiently and damage to the pumps can be
avoided.
At initial power-up, this display will
appear, and the system will show 4 sets
of numbers in succession (ie. 49 then
88 then 21 then 24). These numbers
represent the current software revision,
and the system input voltage.
After the initial software indicators
are shown, this display will appear. This
display is indicating that the system is
in PUMP PRIMING MODE. This mode
will last for 4 to 5 minutes before
automatically exiting and entering the
Flashing
normal operation mode. You can also
manually exit PUMP PRIMING MODE
after the pumps are primed (see PUMP
PRIMING MODE).
Definition: 'Priming' a pump is a term used to describe the
process in which air trapped in the plumbing and pump
wet-end (referred to as an 'air lock') is released, allowing
the pump to move water efficiently through the plumbing
system and to the jets.
While in this mode, the heater circuit is disabled to
allow the priming process to be completed without the
possibility of energizing the heater element during low flow or
no flow conditions. The system will not automatically activate
any of the functions, however, the pumps can be manually
activated by pushing the
control.

MODE, it will automatically exit after 4 to 5 minutes. Be sure
that the pumps have been primed before exiting this mode.
TEMPERATURE CONTROL
FUNCTIONALITY AND ADJUSTMENT
After you manually or automatically exit the PRIMING
MODE, your hot tub will automatically heat to the factory
preset default temperature of 37.5˚C. The topside panel will
briefly show the default temperature, and then the display
will appear as follows:
Note that the water temperature is not

approximately 2 minutes of water
