Priming Mode
– M019*
This mode will last for 4-5 minutes or you can manually exit the priming mode after the
pump(s) have primed.
Regardless of whether the priming mode ends automatically or you manually exit the
priming mode, the system will automatically return to normal heating and filtering at the
end of the priming mode. 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 pushing the “Jets”
button.
If the spa has a Circ Pump, it can be activated by pressing the “Light” button during
Priming Mode.
Priming the Pumps
As soon as the above
display appears on the panel, push the “Jet” button once to start
Pump 1 in low-speed and then again to switch to high-speed. Also, push the Pump 2 or
“Aux” button, if you have a 2nd pump, to turn it on. The pumps will now be running in high
speed to facilitate priming. If the pumps have not primed after 2 minutes, and water is not
flowing from the jets in the spa, do not allow the pumps to continue to run. Turn off the
pumps and repeat the process.
NOTE: Turning the power off and back on again will initiate a new pump priming session.
Sometimes momentarily turning the pump off and on will help it to prime. Do not do this
more than 5 times. If the pump(s) will not prime, shut off the power to the spa and call for
service.
Important: A pump should not be allowed to run 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
You can manually exit Priming Mode by pressing the Up Arrow (Warm) or Down Arrow
(Cool) buttons.
