The YC-800 pharmaceutical refrigerator cannot be placed in an excessively low temperature environment. If the refrigerator senses the low temperature conditions, it will automatically shut down, preventing it from functioning and operating normally. Especially when the natural ambient temperature is below five degrees Celsius, the refrigerator must be moved to a warmer location and restarted.

When setting the temperature of the refrigerator initially, it should not be adjusted too low. The temperature should be gradually adjusted so that it can quickly reach the desired temperature. If the items placed inside the refrigerator have a relatively high temperature, it can also affect the temperature of the internal structure of the refrigerator. When starting to use the refrigerator, the temperature should be set to around the fifth level. This temperature is more suitable for placing items. Although the lower the temperature, the better for storing items with internal structures, too low a temperature can also harm the food and other items placed inside the structure, causing them to freeze.
When using a cooling cabinet for the first time, don't rush to place items inside. Instead, allow the cooling cabinet to operate independently for at least four hours, until the internal temperature has been fully reduced. Then, place the items inside, so that they can be evenly cooled. In summer, the cooling cabinet should be allowed to operate for at least six hours before placing items inside.
