Electric water heater installation diagram, electric water heater installation precautions

In the past, people used to bathe in water. Now people's living standards are constantly improving, and electric water heaters have emerged. This is very convenient for many families. The use of electric water heaters is very convenient, but the installation process is not very simple, there are still many professional technologies included. Here we take a look at the installation diagram of the electric water heater and the precautions for the installation of the electric water heater.

Electric water heater installation diagram

The installation method of the electric water heater is shown in the figure below. The following small series briefly introduces the steps:

1. Before installation, first prepare the required tools: one drill, one Phillips pen, and a square plastic template. First fix the wall with a square plastic stencil. The height is adjusted according to your own family. After fixing, fix it with the screws provided by the factory, and then fix it with two holes.

2. Let's first check to see if the electric water heater we bought is available. After receiving the new water heater, check if it is damaged. If the water heater is in good condition, we will find two hooks behind the water heater to fix the water heater.

3. Be sure to specify the location of the installation. First determine and use the pen to mark the installation position, impact drill holes and install expansion bolts, fix the water heater (if there is no impact drill, you can use the fine iron wire to bind the water heater to the fixture, and it can be firm.

4, according to the size of the electric water heater to screw. Measure the distance between the hooks and draw the position of the drill hole on the wall according to the length and width of the water heater. After the position is drawn, open the eye, then knock the expansion screw in, and knock it in. This will make it stronger. Then use pliers or a plate to tighten the screw so that it is facing up so that the water heater can be hung up.

5. After installing the screws, you can install the water heater. Align the hook on the rear of the water heater with the position of the expansion screw and hang it up. It is best to install a bracket under the water heater to prevent it from falling off.

6. The next step is to ground the line. The step of bottoming the line is very important. He can protect the shower against a protective wall. There are no ground wires connected to the house, and some direct ground wires. If there is no ground line on the first floor, directly hit a line outside the window and go underground to a depth of less than 1 m 5 . In the second floor or above, directly put a hole directly on the wall of the back of the water heater, put a nail into the hole, and then pour some water into it.

7. Before the start, the final check is also required. After the water heater is fixed, the water and water are connected. Accurately connect the power line, neutral and ground wire, and use 16A plug and socket connection. Check the water and electricity connection once and confirm that it is correct. First connect to the water inlet of the water heater from your own outlet, then connect the water outlet of the water heater to your own water inlet, then plug in the power supply and heat it.

Electric water heater installation precautions

1. The location of the installation should be selected. The place where the electric water heater is installed must be noted. The installation method of the electric water heater is mainly indoor wall-mounted, and the space around the water heater should be convenient for inspection; avoid the place where the flammable gas leaks or the environment with strong corrosive gas; avoid the place where the strong electric power and the strong magnetic field directly act; A place where vibration is easy to open.

2, to be installed on the load-bearing wall. The installation position of the electric water heater is basically in the bathroom. The installation location should be the load-bearing wall. Generally speaking, the requirements for each merchant of the electric water heater installation should be selected as the load-bearing wall. The load-bearing wall refers to the solid brick wall with the wall thickness exceeding 24 cm. Or concrete walls or concrete girders are all load-bearing walls. Do not choose a lightweight wall or a partition wall as the installation location of the electric water heater. The bearing capacity of these walls is not strong, so as to avoid hidden dangers for future home life.

3. Do not install near the outlet. The circuit installed in the electric water heater must have a grounding wire to avoid short circuit between the circuit and the water circuit. The socket for the electric water heater is used to avoid the shower area, and the socket with the switch needs to be selected, and the waterproof box must be equipped to prevent the water from entering the jack, causing a short circuit problem.

4. Fully consider the problem of drainage. When the water heater pipe leaks or the safety valve is relieved, the drainage should be able to be drained smoothly without damaging the nearby device; the safety valve relief drain should be kept down and installed in the floor drain or drain of the frost-free environment. The water heater should be as close as possible to the hot water point with the highest frequency of use.

The installation of electric water heaters is still quite complicated. In fact, it is difficult to install the wires. Usually, if you have experience in this area, you can install it yourself, but if you don't have experience, it is recommended to ask a professional worker to install it, because it requires a certain amount of electrician knowledge. After reading the small electric water heater installation diagram and the electric water heater installation precautions, have you grasped the main points?
