How should the electric water heater be maintained?

How to maintain the electric water heater first needs to choose a suitable installation environment

1. The wall installed on the hook must be a solid wall with a thickness greater than 10cm. It is best to install a stronger bracket when installing a capacity of 80 liters or more;

2. The installation environment should be a place that is relatively dry and ventilated, there is no other corrosive gas, and the water and sunlight can not directly contact;

3. There must be a reliable floor drain indoor to facilitate drainage;

4. The power supply must have a reliable grounding or leakage protection device;

5. The water pressure of the electric water heater is normal, generally no more than 0.7mpa, if the water pressure is indeed too high, you must install a pressure reducing valve in front.

How to maintain the electric water heater:

1. Regular inspection, cleaning and maintenance. Household gas water heaters are usually cleaned once every 6 to 8 months to reduce the discharge of harmful substances and save gas. Regular cleaning of the liner. When used for a long time, due to the long-term precipitation of trace impurities and minerals contained in the water, if it is not cleaned regularly, it will affect the water quality and service life of the effluent; the liner is cleaned every six months, the cleaning method is to first cut off the power , Close the inlet valve, and then open the outlet valve, turn the drain switch on the safety valve counterclockwise by 90 degrees to naturally drain the water and sediment in the water heater. Then rinse with tap water. After cleaning, return the drain switch to its original position, and pay attention to that it can be electrified after the water is full.

2. Regular inspections no less than once a year, carefully check and eliminate the safety performance and other potential hidden dangers; users who do not turn off the power of the water heater all the year round should always check whether the water heater is normal, and send it for maintenance in time if there are abnormal conditions Point repair. When the water heater is used normally, replace the thermostat and heater at the designated maintenance point every three years. Replace the overdue water heater in time. Electric water heaters should be inspected and maintained once a year, because there are more or less impurities in the water. After the heating body is used for a period of time, it is easily corroded by the alkaline substances in the water, which will also affect the safety performance of the electric water heater.

After the electric water heater is used for a period of time, scale will easily accumulate on the heating pipe, which seriously affects the heating efficiency and consumes electrical energy. Therefore, the general electric water heater needs regular maintenance of the heating pipe. In addition, the inner liner of the electric water heater should be cleaned every six months. The cleaning method is to first cut off the power, close the inlet valve, and then open the outlet valve, rotate the drain switch on the safety valve counterclockwise by 90 degrees, and naturally drain the water and water in the water heater. Precipitate. Then rinse with tap water. After cleaning, return the drain switch to its original position, and fill it with water before powering on.

3. When not in use for a long time, turn off the power and empty the water storage of the liner; if the amount of water in the shower is reduced, clean up the clogged debris in time to ensure the outlet is unobstructed and help extend the life of the water heater. If you do not use the water heater for a long time, you should first unplug the power supply to make the water heater off. This is mainly for safety. If you do not use it for a long time, the water heater will be in working state. This will cause the components in the water heater to accelerate aging and shorten the water heater. Service life

4. Never replace the parts on the water heater by yourself. Do not repair without permission. Contact the designated maintenance organization in time. After the maintenance staff arrives, the public is advised to check the warranty certificate issued by them. In order to ensure the normal use of the water heater, the safety valve needs to be maintained at least once a month to ensure the normal pressure relief of the safety valve.

How to maintain the electric water heater

1. When not using the water heater for a long time, please turn off the external main power switch.

2. The water outlet must be opened when filling the water, and only after the air in the liner is completely discharged can the water be filled;

3. Regularly remove residual dirt on the shower head and the water screen to ensure smooth flow of water and help extend the service life of the water heater.

4. Do not use acidic or alkaline cleaning liquid to scrub the shell of the electric water heater. When cleaning, you should choose to use a neutral detergent. After wiping, use a damp cloth to gently dry it. Turn off the power supply before cleaning.

5. The power supply must be cut off before emptying;

6. Do not spray water on the air switch or the fuselage during use to prevent the electrical components from getting wet.

7. For closed installation, the inlet valve must be open during heating;

8. If it is suspected that the water in the water heater may freeze, it is forbidden to connect the water heater to the power supply.

9. In the case of large water pressure, the pressure relief valve may drop water, which is normal. It is strictly forbidden to block the pressure relief port, and the diversion pipe can be used to lead to a safe sewer, and ensure the communication with the atmosphere. If the tap water pressure is too high, it is recommended to add a pressure relief valve away from the water heater.

10. When opening the valve, do not point the direction of the water at the human body.

11. The water outlet of the water heater must not be connected to any water valve or shower not provided by the company, so as not to affect the bathing effect.

12. If the water heater is faulty or abnormal, please contact the seller in time and send it to the maintenance station for repair.

13. If the machine is installed for the first time or in case of water outage, please note that the water can only be electrified after being filled with water.

14. Do not disassemble the machine by yourself and replace the parts on the water heater.
