Fill It Up; Priming The Pumps - Master Spas LSX 700 Owner's Manual

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 will display a splash, or
startup screen.
Exit Jets 1 Jets 2
Priming Mode
The 24 hour Circ Pump can be activated by pressing the dedicated "Light" button during
Priming Mode.
Manually exit Priming Mode by pressing the "Exit" Button.

PRIMING THE PUMPS

As soon as the Priming Mode screeen 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 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 navigating to the "Back" button on the Priming Mode
Screen. Note that if you do not manually exit the priming mode as described above, the prim-
ing 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.

PRIMING MODE
After the initial start-up sequence, the control will enter
Priming Mode and display a Priming Mode screen. Only
Jets 3 Circ
pump icons appear on the priming mode screen. The
system will automatically return to 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
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.
