A Series Spas- A900
Preparation and Filling
Fill the spa to its correct operating level. Be sure to open all valves and jets in
the plumbing system before lling to allow as much air as possible to escape
from the plumbing and the control system during the lling process. After
turning the power on at the main power panel, the top-side panel will display
a splash, or startup screen.
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. e system will automatically return to normal heating and ltering at
the end of 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-ow or no-ow conditions.
Nothing comes on automatically, but the pump(s) can be energized by select-
ing the “Jets” buttons. If the spa has a Circ. Pump, it can be turned on and
o by pressing the “Circ Pump” button during Priming Mode. Manually exit
Priming Mode by pressing the “Exit” button.
Priming the Pumps
As soon as the Priming Mode screen ap-
pears 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.
e pumps should be running in high-
speed to facilitate priming. If the pumps
have not primed after 2 minutes, and water
is not owing from the jets into the spa,
do not allow the pumps to continue to run.
Turn o the pumps and repeat the process.
NOTE: Turning the power o and back on again will initiate a new pump
priming session. Sometimes momentarily turning the pump o and on will
help it to prime. Do not do this more than 5 times. If the pump(s) will not
prime, shut o 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.
