Chapter 4 Precautions for low-temperature screen-removal refrigerators

1. Power supply voltage requirements: 220V/50HZ 220V/60HZ. The voltage is 187-242V. If it exceeds this range, the compressor may be damaged;

2. Use a three-pin power socket, which must be reliably grounded; if you feel an electric shock on the metal parts of the refrigerator during use, stop using it immediately;

3. If you need to lengthen the power supply cable, the cross-sectional area of ​​the wire≥ 2.5mm2, the wire can be single strand or multiple strands. It is strictly prohibited to use multi-purpose sockets for connection. The cross-sectional area of ​​the copper core wire in the wall connected to the power socket must also be guaranteed to be above 4mm2;

4. Do not pull the power plug of the refrigerator by pulling the power cord. The power cord cannot be pressed by the refrigerator itself or other objects;

5. It is strictly prohibited to put flammable and explosive dangerous goods, as well as highly corrosive acids, alkalis, etc. in the refrigerator;

6. Do not store or use gasoline and other flammable items near the refrigerator to avoid fire;

7. Do not place heavy objects or water containers on the low-temperature refrigerator with the screen removed to avoid crushing the sealing strip or overflowing water, causing leakage;

8. Do not spray or rinse the refrigerator with water to avoid affecting the electrical insulation performance of the refrigerator;

9. Do not put glass bottles of beer, drinks, etc. into the freezer to avoid freezing and bursting;

10. When there is a power outage or the refrigerator is turned off and needs to be restarted, there must be at least 5 minutes between restarts, otherwise the compressor will not start or the compressor will be damaged;

11. Do not dismantle or modify the refrigerator without permission, and do not damage the internal pipelines at all levels;

12. The tilt angle of the refrigerator should not exceed 45 degrees during transportation and placement.

Chapter 5 Environmental Requirements for Low Temperature Screen-Removal Refrigerators

1. The place should be placed away from heat sources and away from direct sunlight to avoid affecting performance;

2. The place where it is placed must have a flat and solid ground. If any unevenness is found, the Forma wheel nut can be adjusted appropriately;

3. The place where it is placed should not be damp and must be ventilated and dry. The distance around the refrigerator from the wall should be greater than 10 cm to facilitate heat dissipation;

4. Use it in an environment with a humidity of 45% to 75% and an ambient temperature of 5°C to 30°C; it is not allowed to be used in an environment with a relative humidity greater than 85%, otherwise it may cause leakage and other malfunctions.It is recommended to use it in an air-conditioned environment.

Chapter 6 Preparing for use

1. Unpack the refrigerator: Remove the refrigerator from the packaging and place it according to the environmental requirements in Chapter 5;

2. Check the random accessories: instruction manual, etc.;

3. Clean the low-temperature split-screen refrigerator: surface and freezer (never let the refrigerator be cleaned while it is working);

4. After completing steps 1-3, let the refrigerator stand for more than 4 hours before turning it on to avoid oil circuit failure (refrigerator after transportation).

Chapter 7 Start using the low-temperature split-screen refrigerator

Introduction to the setting panel of the low-temperature split-screen refrigerator

1. Plug in the low-temperature screen-opening refrigerator and turn on the power switch. After 3 minutes, the compressor starts to work and the LED displays the current freezer temperature;

2. Listen carefully to the sound of the compressor when it is running: whether there is the sound of pipes colliding with each other, whether there is vibration noise, if so, check whether the various pipes of the refrigerator are in contact, whether they are placed smoothly and make corresponding adjustments.If the problem cannot be solved, the power should be cut off immediately and contact the manufacturer;

3.Enter the freezing temperature setting mode: press the SET button once, the LED will display SP, press the SET button again, the LED will display the current temperature set value. At this time, each time the temperature △ button is pressed, the temperature set value will increase by 1°C (below -100°C, it will increase by 0.5°C each time);

4. After setting, return to the temperature value display mode before the ultra-low temperature screen is removed: Press the SET key and the ▽ key at the same time to return to the current temperature display mode from the freezing temperature setting mode;

5. After the temperature is reached, open the refrigerator door, place the mobile phone to be disassembled in the freezer for a minute or two, then open the refrigerator door and take out the mobile phone to perform degumming related work;

6. After completion, turn off the power switch of the refrigerator.

Chapter 8 Energy Saving Methods for Low Temperature Screen-Removal Refrigerators

1. Shorten the door opening time as much as possible to reduce the loss of cold air in the freezer;

2. In the event of power failure or power outage, try not to open the refrigerator door;

3. Place the refrigerator in a ventilated and cool place.

Chapter 9 Maintenance and maintenance of low-temperature screen-removable refrigerator

1. Every once in a while, use an air gun or vacuum cleaner to remove the dust on the condenser of the low-temperature screen disassembler to avoid affecting the heat dissipation effect;

2. After the refrigerator has been working for a period of time, frost will form on its inner surface, which will affect the cooling effect and increase power consumption. Defrost should be performed when the frost layer is too thick or the cooling speed slows down.To speed up the defrosting process, use a hard film to quickly scrape off the frost on the freezing plate.

Chapter 10 Common faults of low-temperature screen-removal refrigerators

1. Turn on the power switch, and the low-temperature screen remover does not respond. Check whether the power plug of the refrigerator has power. If there is power, please contact the manufacturer;

2. The compressor of the low-temperature screen-opening refrigerator does not work. Reason: the temperature has been reached and it is not turned on repeatedly every 5 minutes. The power is cut off and then turned on again. If not, please contact the manufacturer;

3. The temperature of the low-temperature refrigerator with the screen cannot be lowered. Reason: The temperature value is not set. Reset it. If not, please contact the manufacturer;

4. Loud working noise: Reason: The refrigerator is not leveled, and the internal components rub against each other or become loose. Level the refrigerator or check the internal components.
