7. Cleaning & Maintenance
1. Before cleaning, cut off the power and have the work done after the device cools down to prevent
unexpected accidents.
2. Open the door and take out the internal racks. Clean them with water and detergent.
3. After working every day, clean the internal and external surfaces, chamber and power cord surface with a
wet towel containing non-corrosive detergent. Do not spray the machine with water directly, which may
damage its electrical property and cause electricity safety accidents.
4. After cleaning, install the racks back. Then turn on the power and rotate the thermostat to about 80℃ to
dry the machine. If not going to use the appliance at any time, turn off the thermostat and power switch.
5. If not going to use the appliance for a long period of time, clean it completely and store it in a well-ventilated
warehouse without corrosive gases.
6. Do not clean the appliance with spray pipe.
