NOTE: The look of your topside control panel design and buttons will vary according to
brand and features available on your spa. See table below for pictures and explanation of
TP600 Control Panel button functions.

FILLING YOUR SPA
PREPARATION AND FILLING
Fill the spa 5-6” (13-15cm) below the lip of the spa. Open all valves and jets in the plumbing system before filling to allow as much air as possible to
escape from the plumbing and the control system during the filling process.
PRIMING MODE
This mode will last 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 filtering at the end of the
priming mode. 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/no-flow 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
After the display has gone through screens:
push “Jet” button once to start Pump 1 in low-speed and again to switch to high-speed. Push the Pump 2 button (if you have a 2nd pump) to turn it on.
The pumps will not 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, turn off the pumps and repeat.
NOTE: Turning the power off/on again will initiate a new pump priming session. Sometimes turning the pump off/on helps it to prime. If the pumps will
not prime after 5 times, turn power off 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
Manually exit Priming Mode by pressing either Temperature button. If you do not manually exit the priming mode, it 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
approximately 1 minute of water flowing through the heater to determine the water temperature and display it accurately.
but the display will not show the temperature yet because the system requires
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, Pump 1 low may also
activate for at least 1 minute every 30 minutes to detect the spa temperature 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
The circ pump (if your spa is equipped with one) 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).
Filtration and Ozone
On non-circ systems, Pump 1 low and the ozone generator will run during filtration. On circ systems, the ozone will run with
the circ pump.
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 blower (if there is one) or Pump 2 (if there is one) will run briefly to purge its plumbing to maintain good water
quality.
Freeze Protection
If the temperature sensors within the heater detect a low enough temperature, 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.
In colder climates, an optional additional 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 off by a button press or after it has timed out, a clean-up cycle runs for 30 minutes. Pump 1 on Low Speed and the
ozone generator will run for the set time.. The pump and the ozone generator will run for 30 minutes or more, depending on the system. On some
systems, you can change this setting.
TEMPERATURE & TEMP RA N G E
Adjusting the Set Temperature
Pressing Up or Down temperature buttons will cause the temperature to flash. Pressing a temperature button again will adjust the set temperature in
the direction indicated on the button. When the LCD stops flashing, the spa will heat to the new set temperature.
Press-and-Hold
If a Temperature button is pressed and held when the temperature is flashing, the temperature will continue to change
until the button is released.
Dual Temperature Ranges
This system incorporates two temperature range settings with independent set temperatures. The High Range designated in
the display by an “up” arrow, and the Low Range designated in the display by a “down” arrow.
These ranges can be used for various reasons, with a common use being a “ready to use” setting vs. a “vacation” setting.
The Ranges are chosen using the menu structure below. Each range maintains its own set temperature as programmed by
the user. This way, when a range is chosen, the spa will heat to the set temperature associated with that range.
For example:
High Range may be set between 80°F - 104°F (26˚-40˚C).
Low Range may be set between 50°F - 99°F (10˚-26˚C).
Freeze Protection is active in either range.

MODE - REST AND READY
In order for the spa to heat, a pump needs to circulate water through the heater. The pump that performs this function is known as the “heater pump.”
The heater pump can be either a 2-Speed Pump 1 or a circulation pump.
If the heater pump is a 2-Speed Pump 1, READY Mode will circulate water every 1/2 hour, using Pump 1 Low, in order to
maintain a constant water temperature, heat as needed, and refresh the temperature display. This is known as “polling.”
REST Mode will only allow heating during programmed filter cycles. Since polling does not occur, the temperature display
may not show a current temperature until the heater pump has been running for a minute or two.
Circulation Mode
If the spa is configured for 24HR circulation, the heater pump generally runs continuously. Since the heater pump is always running, the spa will
maintain set temperature and heat as needed in Ready Mode, without polling.
In Rest Mode, the spa will only heat to set temperature during programmed filter times, even though the water is being filtered constantly when in
Circulation Mode.
Ready-in-Rest Mode
READY/REST appears in the display if the spa is in Rest Mode and Jet 1 is pressed. It is assumed the spa is being used and will heat to set temperature.
While Pump 1 High can be turned on and off, Pump 1 Low will run until set temperature is reached, or 1 hour has passed. After 1 hour, the System will
revert to Rest Mode. This mode can also be reset by entering the Mode Menu and changing it.
SHOW & SET TIME-OF-DAY
Setting the time-of-day can be important for determining filtration times and other background features. From the main menu, activate the
temperature flashing. While the temperature is flashing, press “Light” repeatedly until “TIME” is displayed on the screen. Proceed to set current time
using the up and down temperature buttons. When in the TIME menu, SET TIME will flash on the display if no time-of-day is set in the memory. 24-hour
time display can be set under the PREF menu.
Note: If power is interrupted to the system, Time-of-Day is not stored. The system will still operate and all other user settings will be stored. If filter
cycles are required to run at a particular time of day, resetting the clock will return the filter times to the actual programmed periods. When the system
starts up, it defaults to 12:00 Noon, so another way to get filter times back to normal is to start up the spa at noon on any given day. SET TIME will still
flash in the TIME Menu until the time is actually set, but since the spa started at noon, the filter cycles will run as programmed.
FLIP (INVE R T DISPLAY)
From the main screen, activate the temperature flashing. While the temperature is flashing, press “Light” repeatedly until “FLIP” is displayed on the
screen. While “FLIP” is displayed, press either the up or down temperature button to invert the screen. Follow the same procedures to flip it back.
