First check whether the heater is intact and make sure the power cord is not damaged. Use a 220V AC socket with a capacity of no less than 10A. A wall socket is recommended at home. Do not share a power socket with other appliances.
The heater has a built-in tilt switch, which will turn off the heater after the heater is tilted to prevent accidents. The heater can be restored to working condition after being straightened.
