Precautions for using electric water heater-

Precautions for using electric water heaters When using electric water heaters, pay attention to the following points: 1. The indoor wiring of the family should be reliably grounded, and the grounding resistance value should not be greater than 4Ω. Household sockets, regardless of single-phase power supply or three-phase power supply, must be grounded with the ground wire of the power supply, and the grounding pole of the socket is not allowed to be empty. 2. The socket equipped with the electric water heater should be a fixed special socket with a ground wire, and a mobile power terminal board cannot be used. The structure, capacity and jack size of the socket should match the power plug of the electric water heater. The socket should be placed above the horizontal position of the water outlet of the electric water heater to avoid the risk of short circuit caused by water splashing. 3. When using the electric water heater, do not turn off the power supply through the switch on the socket, because the leakage protection plug cannot work after the power supply of the socket is turned off, and it cannot provide protection in the event of a fault such as the ground wire being charged. 4. Regularly (usually every week) check and press the test button of the leakage protection plug to confirm that the leakage protection plug can work normally. 5. To maintain and clean the exterior of the electric water heater, cut off the power first, do not spray with water, but wipe with a soft cloth. 6. 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 in the maintenance department or similar departments. 7. The service life of the electric water heater should not exceed 6 years. If it continues to be used beyond the service life, there will be potential safety hazards and need to be replaced in time.
