SPA CONTROLS - ICON SPA TOUCH
FILL IT UP!
PREPARATION AND FILLING
Fill the spa to its correct operating level, using the instructions found in Initial Spa Setup under the
Installation Instructions section.
PRIMING MODE – M019*
After the initial start-up sequence, the control will enter Priming Mode and display a Priming Mode
screen. Only pump icons appear on the priming mode screen. During the priming mode, the heater
is disabled to allow the priming process to be completed without the possibility of energizing the
heater under low-flow or no-flow conditions. Nothing comes on automatically, but the pump(s) can
be energized by selecting the "Jet" buttons. If the spa has a Circulation Pump, it can be turned on
and off by pressing the "Circ" button during Priming Mode.

minutes, and water is not flowing from the jets in the spa, do not allow the pumps to continue to
run. Turn the spa off, then back on and repeat the process.
NOTE: Turning the power off and back on again will initiate a new pump priming session. Do not
do this more than 5 times. If the pump(s) will not prime, shut off the power to the spa and see
instructions for relieving an air lock in the Initial Spa Setup section.
IMPORTANT: A pump should not be allowed to run continuously without priming for more than 2
minutes. Under NO circumstances should a pump be allowed to run without priming beyond the
end of the 4-5 minute priming mode. Doing so may cause damage to the pump and cause the
system to energize the heater and go into an overheat condition.
EXITING PRIMING MODE
The system will automatically enter the normal heating and filtering at the end of the priming
mode, which lasts 4-5 minutes. You can manually exit Priming Mode by pressing the "Back" button
on the Priming Mode Screen. Note that if you do not manually exit the priming mode as described
above, the priming mode will be automatically terminated after 4-5 minutes. Be sure that the
pump(s) have been primed by this time. Once the system has exited Priming Mode, the top-side
panel will display the Main Screen, but the display will not show the water temperature yet, as
shown below. This is because the system requires approximately 1 minute of water flowing through
the heater to determine the water temperature and display it. The panel will display the following
until it is able to get a temperature read:

PRIMING THE PUMPS
As soon as the Priming Mode screen appears on the
panel, select the "Jets 1" button once to start Pump 1
in low-speed (if applicable) and then again to switch
to high-speed. If the pump is operating but there is
