PRIMING THE PUMPS
As soon as the Priming Mode screen 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 prim-
ing 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
The system will automatically enter the normal heating and filtering at
the end of the priming mode, which lasts 4-5 minutes. You can manually
exit Priming Mode by pressing the “Exit” button on the Priming Mode
Screen. Note that if you do not manually exit the priming mode as de-
scribed above, the priming 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 dis-
play 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 tem-
perature and display it.
SPA BEHAVIOR
PUMPS
On the Spa Screen, select a “Jets” button once to turn the pump on or
off, and to shift between low- and high-speeds if equipped. If left run-
ning, the pump will turn off after a time-out period.

NON-CIRC SYSTEMS
The low-speed of pump 1 runs when the blower or any other pump is on.
If the spa is in Ready Mode, Pump 1 low may also activate for at least 1
minute every 30 minutes to detect the spa temperature (polling) and then
to heat to the set temperature if needed. When the low-speed turns on
automatically, it cannot be deactivated from the panel, however the high
speed may be started.
CIRCULATION PUMP MODES
If the system is equipped with a circ pump, it will be configured to work in
one of three different ways:
1. The circ pump operates continuously (24 hours) with the exception
of turning off for 30 minutes at a time when the water temperature
reaches 3°F (1.5°C) above the set temperature (most likely to happen
in very hot climates).
2. The circ pump stays on continuously, regardless of water
temperature.
3. A programmable circ pump will come on when the system is check-
ing temperature (polling), during filter cycles, during freeze conditions,
or when another pump is on. The specific Circulation Mode that is used
has been determined by the Manufacturer and cannot be changed in
the field. Other device options may be available, like Blower, Light,
Mister, etc.
FILTRATION AND OZONE
On non-circ systems, Pump 1 low and the ozone generator will run dur-
ing filtration. On circ systems, the ozone will generally run with the circ
pump, but can be limited to filtration cycles. The system is factory-
programmed with one filter cycle that will run in the evening (assuming
the time-of-day is properly set) when energy rates are often lower. The
filter time and duration are programmable.
A second filter cycle can be
enabled as needed. At the start of each filter cycle, the water devices like
blower, mister device (if these exist) and other pumps will run briefly to
purge the plumbing to maintain good water quality.
FREEZE PROTECTION
If the temperature sensors within the heater detect a low enough tem-
perature, then the water devices automatically activate to provide freeze
protection. The water devices will run either continuously or periodically
depending on conditions. In colder climates, an optional freeze sensor
may be added to protect against freeze conditions that may not be
sensed by the standard sensors. Auxiliary freeze sensor protection acts
similarly except with the temperature thresholds determined by the
switch. See your dealer for details.
CLEAN-UP CYCLE (OPTIONAL)
When a pump or blower is turned on by a button press, a clean-up cycle
begins 30 minutes after the pump or blower is turned off or times out.
The pump and the ozone generator will run for 30 minutes or more, de-
pending on the system. On some systems, you can change this setting.
