FILL IT UP!
Preparation and Filling
Fill the spa to its correct operating level, 2/3 up the skimmer. Be sure to open all valves and
jets in the plumbing system before filling to allow as much air as possible to escape from the
plumbing and the control system during the filling process. After turning the power on at the
main power panel, the top-side panel will display a splash screen or startup screen.
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.
You can manually exit Priming Mode by pressing the “Back” button on the Priming Mode
Screen. As soon as the Priming Mode screen appears on the panel, select the Jets 1 button
once to start Pump 1 in low-speed and then again to switch to high-speed. Also, select the
other pumps, to turn them on. The pumps should be running in high-speed to facilitate prim-
ing. 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. Some-
times 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
The system will automatically enter the normal heating and filtering at the end of the priming
mode, which lasts 4-5 minutes.
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: when water flows from the jets and all air is purged from the system.
Once the system has exited Priming Mode, the top-side panel will display the Main Screen, but
the display will 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.
