3. Operation instructions
3.1 Installation
Please follow the steps when the chiller is used for the first time:
1. Open the package and check if the machine is in good condition and the accessories are
complete.
2. Open the cap and add water. Add pure water or other clean antifreeze until it is above the
minimum liquid level. In order to achieve better performance, it is recommended to reach
as close as possible to the highest liquid level, and the maximum water injection amount is
about 1.8L.
3. Be sure to connect the external waterway before starting operation. The water inlet and
outlet are all G1/2 internal threads, and users can prepare quick couplings or pagoda joints
with G1/2 external threads for connection.
4. Connect the chiller to 220V power, and press the switch to power on. After power on, the
chiller is in a stopped state. You need to operate the display screen to boot up, see the next
section for details.
5. If the external pipeline is long, the water level will drop slightly after the first start-up. You
can replenish a proper amount of fluid from the water injection port.

3.2 Display Setting
The display screen is divided into a display area and an operation area, as shown in the figure above.
Display area includes: RUN, STOP, ERROR, CHILLING, HEATING. Etc.
Working indication: when lit, it means the chiller is on (the AUTO indicator in the
upper right corner lights up at the same time, indicating that the water temperature is under
automatic control);
Stop indication: when lit, it indicates that the chiller is in the shutdown state
(including power off and fault status);
Flow indication: indicates that the following number is water flow value;
6
(For products without flow monitoring function, this mark will not light up).
This area displays 2 types of contents:
a) During normal operation, the real-time flow will be displayed; for example: "06" means the
flow is 6.0~6.9L/min, press the "up" key to display one decimal place.
b) In the fault state, the fault code is displayed.
Fault indication: when lit, it indicates that the chiller is in a fault state;
Dynamic flow indication: when the flow rate is not zero, the 3 arc-shaped icons will
cyclically light up; when the flow rate is zero, all 3 arc-shaped icons will flash;
Compressor speed indication: When the chiller uses a DC compressor, this icon
indicates the compressor speed; when an AC compressor is used, the fixed speed is displayed here.
Cooling indication: when lit, the compressor is working and the chiller is in the cooling
state;
Heating indication: when lit, it indicates that the internal heating device is in working
condition;
High temperature alarm indication: when lit, it means that the water temperature
exceeds the high temperature alarm threshold;
Setting value: Under normal circumstances, display the set target temperature;
when setting the flow alarm threshold, display the flow threshold;
Real-time water temperature: indicates the current water temperature.
Operation area: There are 4 buttons. The buzzer will emit a short "beep" sound when pressed
effectively, and there will be no response when pressed invalid. The specific instructions are as
7
follows:
On/Off button: Press to turn on/off the chiller.
Setting button: click to enter the setting interface. The real-time flow area
shows: “F0”, and each time pressing the set button, this area will cycle to display “F0”,
“F1”, “F2”, “F3” these 4 codes. "F0" means that the target temperature can be set at
this state; "F1" means that the high temperature alarm value can be set at this state;
"F2" means that the low temperature alarm value can be set at this state; "F3" means
that the flow alarm threshold can be set at this state. The set value will be displayed at
this area . Press the setting button again on the "F3" interface, and the
display will return to the normal display state. Stay on any setting interface of "F0",
"F1", "F2", "F3" for more than 10 seconds without any operation, the display will also
return to the normal display state. Specific instructions are shown in the following
table:

the alarm code will display "E5"

When the water temperature is

When the water flow rate is less
than F3, it will alarm, and the alarm
code will display "E4"
Note: Chiller without flow monitoring function have no F3 setting function.
In the setting interface, click this button, the setting value (F0-F3) will increase, and
the value will increase continuously when you press and hold it.

There are 2 functions of this button:
a) In the setting interface, click this button, the set value (F0-F3) will decrease, and the value will
decrease continuously when pressed for a long time.
b) In the state of E5 or E6 failure (see section 3.4), click this button, the buzzer alarm will be
turned off for 10 minutes (the fault code displayed on the screen will not be eliminated, only the
sound will be turned off).
3.3 Data interface description(optional)
The data interface is on the back cover of the chiller and it is a 9-pin serial port. When used for
RS485 communication, the pins are defined as follows:
Function
Pins
RS485
3——A, 8——B, 5——GND
3.4 Fault code and output port description
When the chiller is in a fault or alarm state, the fault status indicator on the display is lit, the flow
display area shows the fault code, and the buzzer alarms. At the same time, the signal
interface outputs corresponding on-off signals. There are 2 signal ports (3-pin aviation plug) on the
back cover of the chiller. The two output signals are exactly the same. By default, only signal port 1
has an output. You can customize both to output at the same time. The fault code description is
shown in the following table:
