Electric water heater use and maintenance methods:
How to maintain the electric water heater first needs to choose the right installation environment
1. The wall mounted on-hook must be a solid wall with a thickness of more than 10cm. When the capacity is more than 80L, it is better to install a firmer bracket;
2. The installation environment should be dry, ventilated, free of other corrosive gases, and water and sunlight cannot be in direct contact with it.
3, indoor need a reliable floor drain, convenient drainage;
4, the power must have a reliable ground or leakage protection device;
5, the water pressure of the electric water heater is normal, generally not more than 0.7mpa, if the actual water pressure is too high, then it must be installed in front of the pressure reducing valve.
How to maintain the method:
1, regular inspection cleaning and maintenance. Household gas water heaters generally need to be cleaned once every 6 to 8 months to reduce the emission of harmful substances and to save gas. Periodically clean the liner. After long-term use, after a long period of precipitation due to trace impurities and minerals contained in the water, if it is not regularly cleaned, it will affect the water quality and service life; the liner is cleaned every six months. The cleaning method is to cut off the power first. Close the inlet valve, and then open the outlet valve. Rotate the drain switch on the safety valve counterclockwise 90 degrees to drain the water and sediment in the water heater. Then wash it with tap water. After cleaning, restore the drain switch to its original position.
2. Not less than one regular inspection per year, careful detection and exclusion of safety performance and other potentially hidden problems; users who do not turn off the water heater power supply should always check whether the water heater is normal or not. Point maintenance. When the water heater is used normally, replace the thermostat and heater every three years to the designated maintenance point. Timely replacement of the extended water heater. Electric water heaters are inspected and maintained once a year, because the water contains more or less impurities. When the heating body is used for a period of time, it can easily be corroded by alkaline substances in the water and it can also affect the safety performance of the electric water heater. After the electric water heater is used for a period of time, the scale easily accumulates on the heating pipe, which seriously affects the heating efficiency and consumes electric energy. Therefore, regular electric heaters need regular maintenance of the heating pipe. In addition, the electric water heater liner should be cleaned once every six months. The cleaning method is to first cut off the power supply, close the inlet valve, and then open the outlet valve, rotate the drainage switch on the safety valve counterclockwise by 90 degrees, and drain the water in the water heater naturally. Precipitate. Then wash it with tap water. After the cleaning is completed, the drain switch is returned to its original position, and the water can be energized after the water is filled.
3, when not in use for a long time, it is necessary to turn off the power supply to empty the inner tank's water. If the amount of water discharged from the shower reduces, it is necessary to clear the blocked debris in time to ensure the smooth flow of the outlet and help extend the service life of the water heater. If you do not use the water heater for a long time, you should first unplug the power plug to make the water heater in a power-off state. This is mainly for safety. If you do not use it for a long time, it will make the water heater in working condition. This will cause the components in the water heater to accelerate aging and shorten the electricity. Water heater service life
4. Do not replace the parts on the water heater yourself. Do not repair it after failure. Contact the designated maintenance organization in time. After the arrival of maintenance personnel, it is recommended that members of the public consult their maintenance and repair certificates. In order to ensure the normal use of the water heater, the safety valve shall be maintained at least once a month to ensure the normal pressure relief of the safety valve.
