QB-04LX2 four pairs machine double freezer freezer refrigeration principle: refrigerator compressor gasification (liquid to gas) is to absorb heat, liquefaction (gas into water) is the release of heat, both are the same refrigerator or air conditioning work principle; (low pressure) of the refrigerant (gas) - through the compressor - (liquefaction) of liquid refrigerant (HPHT) - Radiator (surface of the refrigerator to release heat) liquid refrigerant (low-temperature high-pressure) - Capillary - refrigerator evaporator (around the inner wall of brass box) gasification is to absorb heat, the temperature inside the refrigerator will drop, - (gasification) at low temperature and pressure of the refrigerant through the compressor so complex cycle from the box off heat to the refrigerant for carrying out. Preparation before the four-door double freezer freezer dual use: 1, check the placement of compliance. 2, packing list, an inventory of the attachment is complete. Carefully read the product manual, to conduct a comprehensive inspection in accordance with the requirements of the specification. 3. Check the power supply voltage is within specifications. Power should be 220V, 50Hz single-phase AC power supply, when working properly, voltage fluctuations permitted between 187-242V, if volatile or fluctuated, will affect the compressor is working properly, and even burn the compressor. 4, the application of single-phase three-hole seat check wiring separately. There are no user grounding device should be installed ground wire. When setting up a ground wire, grounding wire can not do with tap water and gas pipes, but can not receive a phone line and a lightning rod. 5. Do not damage the power cord insulation, not the weight of the wire and shall not be free to change or extension cord. 6. After the check, refrigerators, freezers stand for half an hour, the power, carefully listen to the sound of the compressor is up and running properly, if there is another strike against piping voice, if the noise is too large, check the product Whether placed smoothly, each pipe is in contact, and make the appropriate adjustments. If larger abnormal sounds, immediately turn off the power supply, contact a professional repair personnel. 7, refrigerator, freezer before storing food, the first no-load running for some time, and so reduce the inside temperature, then add the food, not too much to store food, try to avoid refrigerators, freezers full capacity dual time dual refrigeration freezer maintenance of knowledge: odors, mainly from the refrigerator compartment, when defrosting the freezer compartment thaw sometimes odors. The smell of the fresh food compartment emitted directly into the deodorant or electronic devices, such as the elimination of deodorant. You can also shut down for the refrigerator compartment thoroughly cleaned. The smell of the freezer, to cut off the power, open the door, after defrosting and clean, with a deodorant or electronic deodorant cleared. If there is no odor, etc., can be cleaned freezer liner and accessory after, put half a cup of white wine (preferably iodine), shut the door, but could not supply, after 24h, can eliminate the odor celebrate Qinggang County Wangkui Qitaihe ShuangYaShanShi Mudanjiang Jiamusi City Suifenhe Harbin Huma Tahe County Qiqihar Wudalianchi Durbat 9.
