1. Before using an electric water heater for the first time after installation, maintenance, or cleaning, always make sure to fill the tank completely with water before powering it on, to avoid damage from dry heating.
2. The power cord should meet the rated current of the electric water heater, and the outlet must have a reliable ground.
3. The heater can reach temperatures above 75℃. If there are elderly or children at home, adjust the water temperature properly before use to prevent burns.
4. If it's going to be unused for a long time, it's best to empty the water and unplug it, especially in winter to prevent freezing and damage to the tank.
5. When cleaning dirt from the surface of the water heater, remember to turn off the power first, then wipe the surface with a damp cloth and dry it with a dry cloth. Do not rinse it directly with water.
6. After a few years of use, dirt can build up inside the water heater, worsening water quality and potentially causing skin itching, so regular thorough cleaning is recommended.
7. If you need to attach a drain pipe to the safety valve's discharge outlet, make sure the pipe points downward to ensure it vents to the atmosphere.
8. Never try to adjust the safety valve yourself to avoid accidents.
9. When using the water heater, try not to frequently switch the power on and off, as insufficient water in the tank may burn out the heating element.
