Safety Precautions
Product Manual
Please ensure that the power outlet has good contact and that
the ground wire is reliably grounded!
Do not use outside of the technical requirements;
Its use in explosive gases is strictly prohibited.
The machine contains compressed gas, which poses an
explosion hazard. Do not attempt to disassemble it yourself.
Relevant laws and regulations must be complied with;
In case of a refrigerant leak:1. Ensure good ventilation (risk of
suffocation);2. Avoid skin contact (risk of frostbite);
If an abnormality occurs, stop operation immediately,
investigate the cause, and take appropriate action.
It is prohibited to use in high temperature (ambient temperature
above 45℃), humid (with condensation), extremely dusty, large
amounts of water vapor, liquid mist and special gases;
Do not place heavy objects on the product;
Do not splash water or get wet in the rain;
Do not put your fingers or foreign objects inside the machine;
It contains electrically charged, moving, and high-temperature
components; disassembly of the outer casing for operation is
prohibited.

Product Manual Product Manual
Please use clean water/purified water/food-grade antifreeze.
Do not add salt, seawater, or chlorine-containing liquids.
Please ensure that the operating voltage of the chiller is stable
and normal!
A mismatch in power frequency can damage the machine! Please
use it safely according to the actual situation.
Please ensure that the air intake and exhaust channels of the
chiller are unobstructed!The air outlet at the rear of the chiller
should be at least 80cm away from any obstructions, and the air
inlet at the front should be at least 20cm away from any
obstructions.
Operating without water is strictly prohibited, as it will damage
the machine.
Because the machine has a built-in frequent start protection,
there will be a delay when the compressor restarts after it has
stopped for a period of time.
The dust filter must be removed and cleaned regularly; severe
blockage can cause chiller malfunctions.Regular cleaning helps
maintain the chiller's heat dissipation capacity and saves
energy.
Please be aware of the impact of condensation!When the water
temperature is lower than the ambient temperature and the
ambient humidity is high, condensation will form on the
circulating water pipes and the surfaces of the devices being
cooled. In such cases, ensure proper insulation of the
connecting pipes.

The ice bath chiller is easy to install and use. For first-time use of a
new machine, please follow these steps: 1. Open the packaging and
check if the machine is intact and if all accessories are included. 2.
Install the filter onto the ice bath chiller's water inlet (use Teflon
tape to seal the connection, paying attention to the arrow direction
on the filter body).
Precautions for use:
(1) The water level in the bathtub must be higher than the
equipment's inlet, and the equipment must not be placed higher than
the bathtub.
(2) The water inlet pipe of the ice bath machine must be placed close
to the ground and must not be raised, otherwise it will prevent
normal water intake.
4. Connect the water inlet and outlet pipes according to the
equipment specifications. Connect the power supply and turn on the
power switch.(Never turn on the machine without water.)

Product Manual Product Manual
(1) After turning on the power switch, the chiller's circulating pump
will start working. When a new machine is started for the first time,
there will be a lot of air bubbles in the pipeline, which may cause the
machine to occasionally alarm for flow. After running for a few
minutes, it will return to normal.
(2) After the first power-on, you must immediately check the water
pipes for leaks.
(3) After turning on the power, if the water temperature is lower than
the set temperature, the machine's fan and other components will
not work, which is normal. The thermostat will automatically control
the working status of the compressor, fan, and other components
according to the set control parameters.
(4) Because the compressor and other components have a relatively
long start-up process, ranging from tens of seconds to several
minutes depending on different working conditions, to protect the
lifespan of electrical appliances, do not frequently turn the machine
on and off.
5. Adjust the thermostat parameters. The ice bath chiller uses a WIFI
digital display thermostat, which supports operation via the display
screen and mobile APP operation (WIFI required).

1. Button Lock: The button will lock after 15 seconds of inactivity.
To unlock the button: Press the SET button for 2 seconds.
2. Temperature Control (Stop Temperature) Adjustment: Press the
SET button to flash the control temperature display, then press or
The key changes the value and remembers it.
Press the SET button to exit the adjustment mode and display the
measured temperature; if no button is pressed, the measured
temperature will resume display after six seconds. (Temperature
adjustment range: parameter E1~E2)
3. Cooling indicator light: The cooling indicator light is on during the
cooling process; the cooling indicator light is off when the
temperature is constant; the cooling indicator light flashes during
the delay process.
4. Heating indicator light: When the compressor is off, the heating
light goes out; when the compressor is on and the four-way valve is
on, the heating light illuminates and flashes during the delay.
5. Power On/Off: Press and hold the button for three seconds to
turn off the cooling mode, turn off the temperature display, display
"---", and stop all control outputs. Press the button again to
display the measured temperature, and after a delay, start the
cooling mode again.
6. Network Configuration Mode: Press and hold the SET and Ctrl
keys simultaneously for three seconds. The display "SAr" will
appear, allowing you to enter the automatic configuration mode for
the wireless router's name and password.
7. Manual defrosting: Press and hold the button for six seconds to
manually enter or exit defrosting mode (effective in heating
mode).guration mode for the wireless router's name and password.

Network Configuration Flowchart:
Step 1: Enter Network Configuration Mode
Note: The key combination for entering network configuration mode
may vary depending on the model of the Wi-Fi
thermostat.Commonly, it's SET (Settings button) + Up or Down
button for 6 seconds. Displaying SAR indicates successful entry into
network configuration mode. Please refer to the instruction manual
for your specific model for detailed instructions.(Taking SF-126W
as an example: With the device unlocked, press and hold the SET
button + Down button until SAR is displayed, indicating entry into
network configuration mode.)

2. Temperature Control: (Press the button once upon initial power-
on to cancel the delay and quickly start the compressor; one-time
activation only.)
2.1 After a delay following parameter E42 (press E41 when powering
on after a power outage or powering on after power off), when the
cabinet temperature ≥ (control temperature + cooling temperature
hysteresis E3), the fan is activated, and the compressor is activated
after a 10-second delay; when the cabinet temperature ≤ control
temperature, the compressor is stopped, and the fan is stopped after
a 5-second delay. To prevent frequent starts, the relay output must
stop for more than the delay time (parameter E42) before restarting.
3. Water Shortage Alarm: After power-on, the water shortage alarm
is activated after a delay of L1 and when L0=1. The alarm is
triggered when the water flow switch is disconnected, all outputs are
shut down, the display shows "NFL" and the cabinet temperature,
and a buzzer sounds. Press any key to silence the buzzer. The alarm
is deactivated after power-off.
4. Abnormal Operating Mode: If the cabinet temperature probe is
short-circuited or the high temperature exceeds the limit (greater
than 120℃/248℉), the display will flash "HH"; if the cabinet
temperature probe is open-circuited or the low temperature exceeds
the limit (less than -45℃/-49℉), the display will flash "LL". The
compressor will operate for 30 minutes and then stop for 15 minutes.
