Electrical
- Please ensure that the required voltage is being supplied at all times.
- The unit should be plugged into a grounded and properly-sized electrical outlet with appropriate
over-current protection. Please refer to the electrical requirements on the unit’s nameplate. - The unit should have its dedicated outlet.
- Do not use extension cords.
- Ensure the unit is not resting on or against the electrical cord.
- If the unit is not in use for a long period of time, please unplug the unit from the outlet.
- To avoid shock and fire hazards, do not plug in or unplug the unit with wet hands.
- After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so could cause damage to the compressor.
Defrost System
- Refrigeration units contain an automatic defrost system.
- Refrigeration coils are kept below the freezing point (32 degrees Fahrenheit).
- During compressor downtime, the evaporator fan continues to circulate air through the evaporator coil.
- This air circulation raises the coil temperature above the freezing point, melting any accumulated frost.
- Run-off water is drained into the evaporator pan and evaporated.
Use
- High liquid content foods should be limited to 50% capacity of the machine’s total cooling capacity.
- To avoid surpassing the internal pressure limit of the compressor and extend the life of the
compressor, allow the unit 2 minutes in between cycles. - After 2 minutes, press the start/stop button; the
compressor will start, and after another 2 minutes, the evaporator fan will start. - In the quick freeze modes, if the start/stop button is pressed, and the temperature of the cabinet is less than the set temperature, the compressor will not start until the temperature is greater than or equal to the set point.

Error Codes
| # | Control | Description |
| HI | Cabinet probe high
Temperature Alarm (Temperature over 113°F) |
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. |
| LO | Cabinet probe low Temperature Alarm.
(Temperature under -49°F) |
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. |
| E01 | Communication Failure Code | Power off and restart the machine, or check that 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.
