Fill it 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.
After turning the power on at the main power panel, the top-side panel display will go through specific sequences. These
sequences are normal and display a variety of information regarding the configuration of the hot tub control.
Priming Mode - MO19*
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 starts 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 can be energized by pushing the “Jets”
or “Aux” buttons.
Priming the Pump
As soon as the above display appears on the panel, push the “Jets” button once to start the Pump in low-speed and then again
to switch to high-speed. will now be running in high-speed to facilitate priming. If the pump has not primed after 2 minutes, and
water is not flowing from the jets in the spa, do not allow the pump to continue to run. Turn off the pump 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 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 “Warm” or “Cool” button. 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 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 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.

Ready Mode and Rest Mode
In order for the spa to heat, a pump needs to circulate water through the heater. The pump that performs this function is
known as the “primary pump.”
Primary pump is a 2-Speed Pump 1, Ready Mode (indicated by ) will circulate water periodically, 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 (indicated by ) will only allow heating during programmed filter cycles. Since polling does not occur, the
temperature display may not show a current temperature until the primary pump has been running for a minute or two.
In Rest Mode, the spa will only heat to set temperature during programmed filter times.
