PREPARATION AND FILLING
YOUR HOT TUB
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 during
the lling process. Air may be trapped
in the plumbing after lling the spa
tub. Remove trapped air by priming
the pumps. Priming will be discussed
shortly.
After turning the power on at the
main power panel, the spa control
panel will display a splash screen
or startup screen. After the initial
start-up sequence, the control will
enter Priming Mode and display a
Priming Mode screen (view next page
(B)). Only pump icons appear on the
Priming Mode screen. During 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.
WHAT IS PRIMING?
Priming removes trapped air from the
plumbing. How do you know when
a pump is done priming? Priming is
complete when water ows from the
jets without air bubbles. So, watch the
jets as you prime the pump. If your
spa has more than one pump, prime
each pump one at a time. Why prime
one at a time? If multiple pumps are
running, it is too dicult to determine
which pump is circulating air bubbles,
or the ow from one pump may hide
the ow from another pump.
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.
PRIMING MODE
Priming Mode will last for 4 minutes,
or you can manually exit Priming
Mode after the pump(s) have primed.
Regardless of whether Priming Mode
ends automatically or you manually
exit Priming Mode, the control system
automatically returns to normal
heating and ltering at the end of
Priming Mode.
