How to use
1. Check before starting:
A) The low temperature box must have an independent power socket and a reliable ground wire. The voltage fluctuation range is 220~240V and the frequency is 49~51HZ.
B) Before connecting the external power supply, you must first check the switch on the panel to ensure that the switch on the panel is in the off state.
2. Start: Plug in the power supply and turn on the power switch on the panel at the same time. At this time, the display head shows the box temperature value. The compressor starts to run after the delay start time set by the computer thermostat.
3. Work: After the box temperature reaches the requirement, quickly and gradually put the stored items evenly into the box.
4. Stop: After use, when you need to stop, you must first turn off the power switch on the panel (display off), and then cut off the external power supply.
5. This box does not have an automatic defrosting function. After using the box for a period of time, the user needs to turn off the power for natural defrosting, otherwise it will affect the refrigeration effect.
