Description
Press the START/STOP button to start the cooling. After 2 hours, check the temperature inside
the cabinet. If the cabinet temperature is greater than or equal to the high temperature alarm
temperature of 45 °C / 113 °F, the temperature display column alternately displays the cabinet
temperature and HI until the temperature is lower than the alarm temperature. At this time,
check whether the door of the machine is closed, or stop the machine to check whether the
temperature probe or compressor is faulty.
Press START/STOP to START the refrigeration, and test the temperature inside the cabinet 2
hours later. If the temperature of the cabinet is less than or equal to the low temperature alarm
temperature of -45°C/-49°F, the temperature display bar will alternately display the temperature
of the cabinet and LO until the temperature is higher than the alarm temperature. At this time to
stop the cabinet temperature probe and other devices to check whether there is a fault.
Power off and restart the machine or check the connection between the motherboard and the
panel cable is connected to the right. Restore factory settings: In the pre-cooling mode, press
the "+" and "-" keys simultaneously for 3 seconds, the temperature bar will display "rS", and
then automatically shut down. Press the Power button to start the machine, and the machine
parameters will be restored to factory Settings. The factory setting is: temperature unit: °C;
Set the temperature value: -18°C; Setting time: 4:00. If there is no mention of the fault, do not
disassemble the machine at will. Please contact our authorized service technician for related
testing and maintenance to avoid safety failure.
