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 during the filling process. Air may
be trapped in the plumbing after filling 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 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 (E).
Only pump icons appear on the priming mode screen.
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.
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 flows 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 difficult to determine which
pump is circulating air bubbles, or the flow from one
pump may hide the flow 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.
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 minute Priming
Mode. Doing so may cause damage to the pump and
in some cases may cause the system to energize the
heater and go into an overheat condition.
EXITING PRIMING MODE
Priming Mode ends automatically. However, you
can manually exit Priming Mode during this time by
selecting the Back Arrow (D) and pressing the SELECT
navigation button (F).
When Priming Mode ends (automatically or manually)
the panel will display dashes (H). Once the control
system cycles water through the heater for one minute,
the dashes will be replaced by the water temperature.
Follow these steps to prime any one-speed
pump, including a circulation pump:
Press the button (JETS 1, JETS 2, etc.) for that pump
once to turn it On. Run the pump for 2 minutes. If
priming is not complete after 2 minutes, turn Off the
pump and repeat the process.
Which pump is the heater pump?
When the spa has just entered Priming Mode, press
the LIGHT button (B) and see if any water flows. If
so, you have a circulation pump serving as the heater
pump. If not, a two-speed pump serves as the heater
pump. A circulation pump is controlled with the LIGHT
(B) button (in Priming Mode only). A two-speed heater
pump is controlled by pressing the JETS 1 (A) button.
Once the heater pump is primed, prime any
additional pumps.
The heater pump is the most
important pump to prime.

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 filtering at the end of Priming Mode.
PRIMING THE PUMPS
There are two ways to prime the pumps (and other
water devices).
#1 - Prime pumps by pressing the Spa Device
buttons (C).
#2 - Prime pumps from the Priming Mode screen (E).
One Priming Mode screen can display a maximum of
six pumps (and other water devices). If there are more
than six devices, a small navigation arrow will appear on
the screen, indicating that more devices are available
to control on the next Priming Mode screen. Press the
RIGHT navigation button (G) to view the next screen.
The techniques for Priming pumps and running spa
devices are almost identical. View page 13 for more
information on running spa devices.
This panel message (E) indicates that the spa is in
Priming Mode. Note: Turning the power Off and back
On again will initiate a new pump priming session.
If you need more than 4 minutes to prime all of the
pumps, cycle power to the spa.
Follow these steps to prime a two-speed pump:
Press the button (JETS 1, JETS 2, etc.) for that pump
once to turn it On at low speed. Press the button again
to run the pump at high speed. Run the pump at high
speed for 2 minutes. If priming is not complete after 2
minutes, turn Off the pump and repeat the process.
