Installation of electric water heater Installation method of electric water heater

Electric water heaters bring consumers a simple and comfortable experience, with low energy consumption and convenient use, and are welcomed by consumers. With people's increasing attention to safety issues, the installation and use of electric water heaters can avoid many unsafe problems. So what is the installation diagram of the electric water heater? Let's take a look at the installation drawing of the electric water heater.

I. Installation Diagram of Electric Water Heater

1. Determine the installation location.

Determine the installation position of the electric water heater and mark it with a pencil. Then fix the water heater. The fixed water heater can be punched with an impact drill and fixed with expansion nails, or it can be fixed and tied to a fixture with thin iron wire, as long as the installation and fixation are firm.

2. Connect water pipes

After the water heater is installed and fixed, take out the water inlet and outlet pipes, tighten them, and then fill the container with water;

Install electric wire

It is necessary to determine the connection of wires, accurately connect the live wire, neutral wire and ground wire of power supply, and determine the connection mode of plugs and sockets;

Detection and use

After installation, the electric water heater should be tested for water and electricity to ensure no water leakage, and it can only be used after the test is normal.

Second, the electric water heater installation requirements

1. must be installed by professionals.

Because of its special performance, the installation of electric water heater is complicated and difficult, and it must be installed by professionals. For example, drilling holes in different walls, special treatment of decorative materials, especially the embedded power cord and water pipe in the bathroom, all need professional instruments to detect and locate in advance before installation. In addition to the close connection of pipes, we should also consider the insulation of hot water, the length and direction of pipes, the cleanliness of appearance and the grounding of water pipes. This can ensure the accuracy of the installation procedure, and can also design different installation schemes according to the specific environment of users to ensure the normal use of the water heater.

2. Standard requirements for household electricity consumption

According to the national standard, the power supply of household appliances should be single-phase three-wire 50 Hz 220 V AC. Three wires of power supply? The live wire, neutral wire and ground wire are connected correctly, in line with external identification, well grounded, well insulated, and the wire diameter meets the capacity load requirements. The allowable deviation of power supply voltage in national power quality is-10% to 7%, and it is between 198 volts and 235 volts according to the standard voltage of 220 volts. For electric water heater products, the deviation is correspondingly expanded to-15% to 10%, that is, 187 volts to 242 volts. In areas where the power load is relatively concentrated, it should be appropriately expanded.

3. Requirements for protection switch

For the water storage electric water heater, a separate power supply line should be set up, and it is not allowed to share a power line with other high-power appliances. Separate protection devices such as leakage, overload and overcurrent should be set up, and the protection current level should not exceed twice the rated current of a single appliance.

4. Requirements for wires and sockets

The power supply wiring should not be too thin, and the power should be more than 50% higher than the rated maximum power consumption of electrical appliances. When the current is 6 amps ~ 10 amps (power 1320 watts ~ 2200 watts), the cross-sectional area of the power supply line should be ≥ 1 mm2. If the current is between 10 amp and 16 amp (power is between 2200 watts and 3520 watts), the cross-sectional area of the power cord shall be ≥1.5mm2; If the current is 16 A ~ 25 A (power is 3520 W ~ 5500 W), the cross-sectional area of the power cord should be ≥2.5 mm2. The wire sheath should be waterproof and wear-resistant, and the wire ends and connectors should be fully connected. After a long time of use, it can be judged simply by holding it without a sense of temperature.

The socket should match the plug of the electric water heater, preferably 16 amp, especially when the rated power consumption of the electric water heater exceeds 2000 watts. It is best to use a waterproof socket with a shell protection to prevent water and steam from entering the connection gap between the plug and the socket. Sockets should be placed as vertically as possible. If it is installed on a wall or other objects, it should be as far away from water sources or shower heads as possible. It is best for bathers not to touch water directly, and to spray water during bathing. The socket should be connected conveniently and firmly to prevent electric sparks caused by poor connection when pulling or touching the power cord. When the power cord is long, it should be bound, pasted and fixed on an immovable object.

5. Requirements for waterways

In order to ensure the best use effect of the electric water heater, the outlet pipe of the electric water heater should be less than three meters, and the power supply should be turned off before the water is turned off after use, so as to avoid dry burning or overheating. Do not use multi-channel water supply for fast electric water heaters. If multi-channel water supply is needed, professional installation guidance is needed. When installing the water heater, be sure to install an angle valve at the inlet end.

6. Installation position requirements

The electric water heater should be installed in a dry place to ensure that the water cannot be sprayed out, and the ventilation and drainage conditions are good, and a floor drain and a diversion pipe should be installed.

The installation of water heater involves waterway, circuit, wall decoration, ceiling, etc. In decoration, hydropower transformation is the first step, and hidden hydropower projects directly affect the normal installation and use of home appliances behind. According to the owner, among all household appliances, the water heater is one of the most important appliances that the owner is dissatisfied with the decoration because of poor communication or preparation in the early stage.

Requirements for installation environment of electric water heater:

1. Avoid places where combustible gas may leak and places where inflammable, explosive and corrosive articles are stored;

2. Avoid places with strong magnetic and electric fields to prevent electromagnetic fields from affecting the work of the water heater;

3. Try to avoid places where vibration occurs, such as train tracks, blasting sites, piling sites, etc.

4. In order to ensure the convenience of later maintenance, at least 30 cm of maintenance space must be reserved at the right end of the electric water heater;

5. The installation location should be convenient for water and electricity. The distance between the water heater and the water point should be shortened as far as possible to reduce the heat loss caused by the long pipeline. The socket should be located above the product to avoid the risk of short circuit caused by water splashing.

6. If the socket is likely to be splashed by water, splash-proof measures or splash-proof sockets should be adopted;

7. The installation position of the product should be put out of the reach of children, and the sockets used should be set as far away from the reach of children as possible;

8, electric water heater installation should avoid direct sunlight or Yuba direct position.

Precautions for installing water heater:

1, the water heater can't be installed in a place with strong air convection (such as opening a window), and flammable materials can't be placed around it.

2. The water heater can't be installed in a "box", or even in a louver.

3. The method of "reverse installation" should be adopted during installation, that is, the water heater should be installed in place first, and then the cold and hot water pipes and gas pipes should be installed in reverse from the water heater.

4. The inlet and outlet pipes must be vertical, and the outlet pipe (hot water) cannot be equipped with valves, otherwise it will affect the water output and use function.

5, gas pipeline must use high quality galvanized pipe, pipe diameter must reach 20 mm, to ensure that there is enough gas source.

6. Soft metal braided pipes and corrugated pipes are not suitable for hot and cold water pipes (if the original corrugated pipes are used, they should be installed straight and the bending angle should not be greater than 90 degrees).

7, water heater gas fittings should not be more, through the ceiling and the cabinet joint application of epoxy resin or plastic soil seal.

8. The power socket of the water heater should be more than 5 cm away from the inlet and outlet pipes, and there should be a switch to cut off the power supply after use.

9. Pressure test and compactness test must be carried out after gas pipeline installation.

10, it is forbidden to use raw tape as filler for gas pipe joints.

1 1, and the installation height of the water heater is generally 165 ~ 175 cm, subject to the fact that the fire window is parallel to people's sight.

12, the water heater should be firm and not loose.

13, the vent holes of the water heater should be separated, and it is not advisable to use public vent holes.
