Spa Controls
Initial Start-Up
PREPARATION AND FILLING
Fill the spa to its correct operating level. 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.
PRIMING MODE
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. The sys-
tem will automatically begin normal heating and filtering
at the end of the priming mode, which lasts 4-5 minutes.
During the priming mode, the heater is disabled to allow
the priming process to be completed without the possibil-
ity of energizing the heater under low-flow or no-flow
conditions. Nothing comes on automatically, but the
pump(s) can be activated by touching the “Jet” buttons.
Manually exit Priming Mode by touching the “Back” Button.
PRIMING THE PUMPS
As soon as the Priming Mode screen appears on the panel, touch the “Jets 1” button once to start
Pump 1 in low-speed and then again to switch to high-speed. Also, touch the other pumps, to
turn them on. The pumps should 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, the pump(s) will need relieved of an air lock. See Installation Instructions for information
on bleeding air from a pump to relieve an air lock. If you need further assistance, your spa dealer
can be contacted. Regular maintenance procedures would not be covered under the spa warranty.
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 touching 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 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.
