Note: the installation diagram is just for reference, the specific
installation scheme should be
determined according to the environment of the actual usage
3. Preparation and installation
3.1. Removing package and checking
1. Please prepare installation tools: knife and scissors, and wear
protective gloves.
2. Please remove wrapping film and packing belt, then remove the
carton, take out the air
conditioner.
3. Please check the attachment list and accessory bags in the
carton, check whether the air
conditioner model is right.
Notes:
1. After removing the outer package, please make sure that the air
conditioner is placed
upright , and not placed horizontally or upside down.
2. After removing the outer package, please check carefully whether
the appearance of the air

deformation or oil stain, please contact the manufacturer in time.
3. If there is no need to install the product immediately or it
needs to be transported to other
place, please repack the air conditioner after the checking.
4. It is recommended to recycle the unpacking materials.
3.2. Mechanical installation
Installation tool: Phillips screwdriver
Installation Steps:
1) Choose cut location on the cabinet according to the holing
diagram, remove the shadow
area and make the installation hole.
2) Make air conditioner flange close to cabinet door, Fix the air
conditioner on the installation
surface of the cabinet firmly with M5 screws.
3) Check whether air conditioner is installed levelly and firmly.
Notes:
1) Check whether air conditioner drainage loop is smooth, in case
that drainage is blocked.
2) When determine the location of the installation hole in the
cabinet, you should avoid the inlet
and outlet air ports inside the cabinet are not blocked by any
components inside the cabinet, and
the two should be kept a horizontal distance of more than 150mm;
otherwise, it is prone to lead
to r short circuit of the return air, and poor cooling effect,
etc.;
3) Carrying or moving the air conditioner should be careful to
avoid colliding it and scratching
its surface coating;

4. Product function
4.1. Cooling
When the temperature inside cabinet is higher than refrigeration
starting temperature, it starts
refrigerating; when the temperature inside cabinet is lower than
refrigeration stopping temperature, it
stops refrigerating.
| Parameter | Default value | Setting range | Unit | Note |
|---|
| Refrigeration starting temperature | 32 | [20~40] | °C | Refrigeration stopping temperature = Refrigeration starting
temperature - Refrigeration return difference |
| Refrigeration return difference | 5 | [3~10] | °C | |
4.2. Heating(Optional)
When the temperature inside cabinet is lower than heating starting
temperature, it starts heating;
when the temperature inside cabinet is higher than heating stopping
temperature, it stops heating.
| Parameter | Default value | Setting range | Unit | Note |
|---|
| Heating starting temperature | 5 | [-10~15] | °C | Heating stopping temperature = Heating starting temperature +
Heating return difference |
| Heating return difference | 10 | [3~15] | °C | |
4.3. Remote monitor
Air conditioner has an RS485 communication interface, supporting
MODBUS- RTU communication
protocol.The air conditioner communicates with the upper monitor through the
RS485 communication
interface. Or users can check the air conditioner’s running state
by viewing the display screen directly and
change its running parameters.
4.4. The control of external fan (Optional)
According to the optional requirement, the external fan (Hydrogen
discharge / emergency fan)19
automatically realizes cycle hydrogen discharging and emergency
ventilation function.
Hydrogen discharge function(Optional):When hydrogen discharge cycle comes, air conditioner start
the hydrogen discharge fan, the control switch closes.
| Parameter | Default value | Setting range | Unit |
|---|
| Cycle | 24 | [0~72] | h |
| Discharging time | 5 | [0~10] | Min |
Emergency ventilation function (Optional): When the temperature
inside cabinet is higher than
Emergency ventilation starting temperature, emergency ventilation
fans run; when the temperature inside
cabinet is lower than Emergency ventilation stopping temperature,
emergency ventilation fans stop.
| Parameter | Default value | Setting range | Unit |
|---|
| Starting temperature | 45 | [28~50] | °C |
| Stopping temperature | 42 | [25~50] | °C |
