What key issues should be paid attention to when installing glass door display refrigerators?

Glass door display refrigerators are an important part of commercial refrigeration equipment and are widely used in supermarkets, convenience stores, restaurants and other places. The correct installation method can not only ensure its efficient operation, but also extend its service life, reduce energy consumption and maintenance costs. During the installation process, it is necessary to comprehensively consider multiple aspects such as location selection, power configuration, handling method, preparation for first use and subsequent maintenance to ensure that the equipment works stably and reliably.

First of all, the choice of installation location is crucial. The refrigerator should be placed in a well-ventilated area away from direct sunlight, because sunlight exposure will significantly increase the burden on the refrigeration system, lead to increased energy consumption, and even affect the overall refrigeration effect. At the same time, sufficient heat dissipation space must be reserved around the refrigerator. It is usually recommended to leave a gap of 10 to 15 cm on the back, top and sides to ensure that the compressor can dissipate heat normally. In addition, the installation ground must be kept flat to avoid tilting the refrigerator, otherwise it may cause the glass door to be poorly sealed, cold air to leak, or the compressor to vibrate abnormally due to uneven force, which may affect the life of the equipment in the long run.

Secondly, power configuration is a key link that cannot be ignored during the installation process. Commercial glass door display refrigerators usually require 220V or 380V voltage, so before installation, it is necessary to confirm whether the store's circuit meets the requirements to avoid damage to the compressor due to unstable voltage. It is recommended to equip the refrigerator with an independent socket to avoid sharing the same circuit with other high-power electrical appliances to prevent tripping or circuit overload. At the same time, the power cord of the refrigerator should be well grounded to ensure safe use and prevent the risk of leakage.

During the handling and installation process, special attention should be paid to the transportation method of the refrigerator. Since the refrigerator contains a compressor inside, it should be kept upright as much as possible during transportation to avoid excessive tilting. If the tilt angle is large during transportation, it is recommended to let it stand for more than 24 hours before installation, and wait for the lubricating oil in the refrigeration system to flow back to the compressor before powering on, otherwise it may affect the refrigeration effect or even damage the equipment. In addition, the glass door is a vulnerable part of the refrigerator. It should be handled with care during transportation to avoid severe vibration or collision to prevent glass breakage or door frame deformation.

Before the first use, necessary inspections and preparations need to be carried out. First wipe the inside and outside of the refrigerator with a neutral detergent, especially the food storage area, to ensure hygiene and safety. Before powering on, it is recommended to let the freezer stand for 2 to 4 hours to allow the refrigerant to fully stabilize. When starting up for the first time, you can set the temperature to -18°C to -22°C (for freezers) or 0°C to 4°C (for refrigerators) and observe whether the cooling effect is normal. If you find that the cooling speed is too slow or the temperature cannot reach the set value, you should promptly troubleshoot the problem and contact a professional for repair if necessary.

The sealing of the door of the freezer directly affects the cooling efficiency, so it needs to be carefully checked after installation. Ensure that the glass door opens and closes smoothly without jamming. The door seal should fit the cabinet tightly. A simple test method can be used to check the sealing, such as clamping an A4 paper when closing the door. If the paper is not easy to pull out, it means that the seal is good. If the door seal is found to be aging or deformed, it should be replaced in time to prevent the cold air from leaking out and increasing energy consumption. In addition, in commercial environments, frequent opening and closing of the door should be minimized to maintain a stable internal temperature.

Finally, the long-term stable operation of the freezer is inseparable from regular maintenance. For direct cooling freezers, manual defrosting is required regularly to prevent the frost layer from being too thick and affecting the cooling effect; while air-cooled freezers usually have an automatic defrosting function, but they still need to be checked regularly. Cleaning the condenser is also important. It is recommended to clean the accumulated dust every 3 to 6 months to ensure heat dissipation efficiency. At the same time, you should pay attention to the operating status of the equipment during daily use. If you find that the cooling effect is reduced or the noise is abnormal, you should find out the cause in time to prevent small problems from turning into major failures.
