Guidance: The first time you use the deli cabinet, you should pay attention to check whether the position of the deli display cabinet is in compliance with the requirements.
Check that the power supply voltage meets the requirements. The power supply for the cooked food display cabinet should be 220 volt, 50 Hz single-phase AC power supply. During normal operation, the voltage fluctuation is allowed to be between 187 and 242 volts. If the fluctuation is large or high, it will affect the normal operation of the compressor. It will even burn the compressor. If the voltage is too high, the motor coil will be burnt due to too much current; if the voltage is too low, the compressor will be difficult to start, causing frequent starts and burning the motor. Therefore, when the power supply voltage fluctuates greatly, a conditional user can install an automatic voltage regulator. It is recommended to use a voltage regulator above 750W.
Dedicated display cabinets use dedicated three-hole sockets for separate wiring. Users who do not have a grounding device should install a grounding wire. When setting the grounding wire, the grounding terminal should be buried deep into the ground at a depth of 2 meters. The grounding resistance should not exceed 0.1 ohm. You can't use the tap water and gas pipes to make the grounding wire, and you can't get the ground wire of the telephone and the lightning rod.
After all the inspections are correct, the cooked food display cabinet is allowed to stand for half an hour. Turn on the power supply and listen carefully to whether the sound of the compressor is normal during start-up and operation. Is there any sound that the pipelines collide with each other? If the noise is loud, check the cooked food display cabinet. Whether it is placed smoothly, whether the various pipelines are in contact, and make corresponding adjustments. If there is a large abnormal sound, immediately cut off the power supply, look for the local maintenance point to check and troubleshoot; before the food storage, the cooked food display cabinet should be idle for a period of time, after the temperature in the box is lowered, then put the food and store the food. Do not overdo it, try to avoid the electric cooker display cabinet running at full load for a long time.
