Precautions for heater dry burning:
I. check whether the heater wire source is connected reversely.
II. When using the heater, do not turn off the power supply through the switch on the socket, because the leakage protection plug can not work after turning off the power supply of the socket, and can not provide protection in case of ground wire electrification and other faults.
3. Check the "test" button of the leakage protection plug regularly to confirm whether the leakage protection plug works normally.
IV. to maintain and clean the outside of the heater, first cut off the power supply, do not spray with oil, and wipe with a soft cloth.
V. if the power cord is damaged, in order to avoid danger, the special power cord provided by the manufacturer must be used and replaced by professionals from the maintenance department or similar departments.
Vi. generally, the service life of electric heater will not exceed 10 years. If the heater continues to be used after the service life, there will be potential safety hazards and it will be replaced in time.
