Preparation and Filling
Fill the spa to its correct operating level. Be sure to open all valves and jets in the plumbing system before fi lling to allow as much air as possible to
escape from the plumbing and the control system during the fi lling process.
After turning the power on at the main power panel, the top-side panel display will go through specifi c sequences. These sequences are normal and
display a variety of information regarding the confi guration of the hot tub control.
Priming Mode – M019*
This mode will last for 4-5 minutes or you can manually exit the priming mode after the pump(s) have primed.
Regardless of whether the priming mode ends automatically or you manually exit the priming mode, the system will automatically return to normal
heating and fi ltering at the end of the priming mode. During the priming mode, the heater is disabled to allow the priming process to be comple-
ted without the possibility of energizing the heater under low-fl ow or no-fl ow conditions. Nothing comes on automatically, but the pump(s) can be
energized by pushing the "Jet" buttons.
If the spa has a Circ Pump, it can be activated by pressing the "Light" button during Priming Mode.
Priming the Pumps
As soon as the above display appears on the panel, push the "Jet" button once to start Pump 1 in low-speed and then again to switch to high-speed.
Also, push the Pump 2 or "Aux" button, if you have a 2nd pump, to turn it on. The pumps will now be running in high-speed to facilitate priming. If
the pumps have not primed after 2 minutes, and water is not fl owing 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 pressing a "Temp" button (Up or Down). Note that if you do not manually exit the priming mode as des-
cribed 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 momentarily display the set temperature but the display will not show the tempe-
rature yet, as shown below. This is because the system requires approximately 1 minute of water fl owing through the heater to determine the water
temperature and display it.

spa Behavior
Pumps
Press the "Jets 1" button once to turn pump 1 on or off, and to shift between low- and high-speeds if equipped. If left running, the pump will turn off
after a time-out period. The pump 1 low-speed will time out after 30 minutes. The high-speed will time out after 15 minutes. On 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 (See page 6), 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 confi gured 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 checking temperature (polling), during fi lter cycles, during freeze conditions, or when
another pump is on.
The specifi c Circulation Mode that is used has been determined by the Manufacturer and cannot be changed in the fi eld.
Filtration and Ozone
On non-circ systems, Pump 1 low and the ozone generator will run during fi ltration. On circ systems, the ozone will run with the circ pump.
The system is factory-programmed with one fi lter cycle that will run in the evening (assuming the time-of-day is properly set) when energy rates are
often lower. The fi lter time and duration are programmable. (See page 10) A second fi lter cycle can be enabled as needed.
At the start of each fi lter cycle, the blower (if there is one) or Pump 2 (if there is one) will run briefl y to purge its plumbing to maintain good water
quality.
Freeze Protection
If the temperature sensors within the heater detect a low enough temperature, then the pump(s) and the blower automatically activate to provide
freeze protection. The pump(s) and blower will run either continuously or periodically depending on conditions.
Cleaning cycle (optional)
When a pump or blower is activated by a push of its button, a cleaning cycle will start 30 minutes after the pump or blower is turned off. The pump
and ozone generator will run for 30 minutes or more, depending on the system. On some systems, this setting can be changed. (See the Preferences
section on page 21.)
