PRIMING MODE
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 “Jet” buttons.
PRIMING 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 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.
EXITING PRIMING MODE
You can manually exit Priming Mode by pressing a “Temp” button (Up or Down). 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 momentarily display the set temperature but the display will not show
the 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.
MODE - READY AND REST
READY Mode will circulate water every 1/2 hour, using Pump 1 Low, in order to maintain a constant water temperature, heat as needed, and
refresh the temperature display. This is known as “polling.” REST Mode will only allow heating during programmed filter cycles. Since polling
does not occur, the temperature display may not show a current temperature until the heater pump has been running for a minute or two.
