4、 Usage:

1. Pre startup inspection:

A) The low-temperature box must have independent power sockets and reliable grounding wires. The allowable voltage fluctuation range is 220-240V, and the frequency is 49-51 Hz.

B) Before connecting the external power supply, it is necessary to first check the switch on the panel to ensure that it is in the off state.

2. Power on: Plug in the power and set the power switch on the panel to the on state. At this time, the display head will show the temperature value of the box. After the delay start time set by the computer thermostat, the compressor starts running.

3. Work: After the temperature of the box reaches the required level, quickly and gradually place the stored items evenly into the box.

4. Shutdown: After complete use, when it is necessary to shut down, the power switch on the panel must first be turned off (the display is off), and then the external power supply must be cut off.
