Qicheng "big bucket" installed unscientific
At present, more than 70% of consumers in China is the bathroom decoration is completed after the purchase of water heaters. This consumption habits, resulting in water heater installed after the pipeline messy and other issues, damage decoration beautiful, and even can not meet the needs of users of hot water.
 The current water heater products, the importance of pre-sale service highlights its installation of the main "water heater installation location and product selection is not reasonable," the two major issues. & Nbsp;
"Improper installation location is mainly reflected in the water heater is not easy to use, the pipeline is too long, there is no reserved space, there is no reserved pipeline, no reserved wire, water heater location on the hollow wall in six areas, and improper product selection The consumer is not on the bathroom water arrangements, water requirements and special requirements to consider clearly, and even after the installation of products and home improvement style had a conflict. "The root of the problem is the housing construction, decoration design does not consider the supply of hot water, and consumers in the Late purchase also lacks professional knowledge and experience. "Therefore, the proposed consumer, first to buy a water heater after the decoration.
 
Pay attention to the electricity environment
 1.Household power supply standard.
In accordance with national standards, household power equipment, power supply should be single-phase three-wire 50 Hz 220-volt AC. Power line of the three lines --- line of fire, zero line, ground connection is correct and consistent with the external logo, good grounding, insulation protection intact, wire diameter thickness to meet the capacity load requirements. National power quality in the supply voltage tolerance of -10% to 7%, according to the standard voltage of 220 volts is calculated between 198 volts to 235 volts. For electric water heater products, the deviation is correspondingly increased to -15% to 10%, that is, between 187 and 242 volts. In areas where the electricity load is relatively concentrated, it should be expanded as appropriate.
 
2.Protection requirements.
Household total meter load can not be exceeded, it is best to have air protection switch, at least a fuse-type protection - such as fuse (wire), fuse (wire) nominal value can not exceed the limit. Water storage type electric water heater should be set separately power supply lines, do not and other high-power electrical appliances (such as Yuba, heater, heater) share a power cord (note from the meter at the connection, rather than from the wall socket, More can not be connected from the middle), set separate leakage, overload, overcurrent protection devices, the level of protection of the current value shall not be greater than a single electrical rated current of 2 times.
 
3.Power outlet and extension cord.
The electrical outlet required for electrical appliances shall be configured as required. According to national standards, single-phase three-wire (hole) socket, the left end of the socket for the N pole, then the zero line; the right end of the L pole, then phase (fire) line; the top end of the ground symbol should be ground, not interchangeable. 
The socket should be matched with the electric water heater plug, preferably 16 amps, especially electric water heater rated power consumption of more than 2000 watts. The socket is best to use a waterproof, housing protection to prevent water and steam from entering the connection gap between the plug and the socket. The socket as far as possible placed vertically, if installed on the wall and other objects, should try to stay away from the water or nozzle, the best bath and bath in the water, water can not be in direct contact. The socket should be easy to secure connection, to prevent the power lead pull, touch, because the connection is not good to produce spark. When the power supply lead is long, it should be bundled, adhered and fixed to objects that are not easy to move.
 
Power supply wiring can not be too small, the power should be greater than the rated power of the maximum power of 50% or more, the current in the 6 ampere ~ 10 amps (power 1320 watts to 2200 watts), the choice of power line cross-sectional area ≥ 1 square millimeter; In the 10 amp to 16 amperes (power 2200 watts to 3520 watts), the choice of power line cross-sectional area ≥ 1.5 square millimeters; current in the 16 amp ~ 25 amps (power 3520 watts to 5500 watts), the choice of power line cross-sectional area ≥2.5 square millimeters. Wire sheath should be waterproof, wear, thread and connector at the full, good solid connection. Long-term use, you can hold a warm sense of simple to judge.
 
  Special reminder: Consumers must not be connected with the power cord, installation and maintenance professionals can not own or change the power supply lead. Changes in the power lines and mating must be carried out by trained professionals with electrical warrants, electrical work is a special operation, must be certified posts.
 
Installation should be carried out by qualified personnel
Professional installation personnel through the enterprise induction training, understanding of product performance, to comply with the installation procedures, master the installation skills, according to the user to use the environment specific design and installation program to complete the installation work.
Electric water heater installation is difficult to fully understand and master the user's use of the environment, such as the structure of the bathroom, the installation of the situation, the power situation.
& Nbsp;
Installers should be based on different environments, products and user needs, to meet the installation requirements on the basis of the product performance to better play, and conducive to future maintenance and repair. Electric water heater installation in the bathroom is very complex, the wall for the solid brick, the concrete wall is more convenient to install the hole, the wall is not load-bearing or bearing walls and other decorative materials such as tiles, the need to take special measures to deal with, so the installer The skill requirements are particularly high. Especially in the bathroom wall may be embedded in the power cord, water pipes and other non-broken objects and the location, the depth is unknown, we must use a professional instrument for pre-detection, positioning.
& Nbsp;
The installation of the electric water heater is, in a sense, more complicated than the installation of the air conditioner, because it involves the connection of the inlet pipe, the outlet pipe, the valve, the waterway conversion valve and the like. In addition to the strict requirements of the pipeline connection, but also consider the hot water insulation, the length of the pipeline and the routing path, the appearance of neat, water pipe grounding.
& Nbsp;
Electric water heater installation, must ensure that the protection of the product function is normal, effective and timely work. For example, the control of water temperature, the control of dry and dry water, the protection of power supply, the control of leakage, the flow of air and so on.
& Nbsp;
Installation or maintenance personnel must explain to the user in detail the precautions, tips for daily safe use and maintenance of the contents of the special circumstances of the treatment methods and measures.
 
Purchase depends on energy efficiency rating
Users in the purchase of electric water heater products, to select the 3C logo products, pay attention to the product's energy efficiency grade logo and the scope of application of the product.
& Nbsp;
When installing the product, the user must check whether the installer has the corresponding professional qualification or the corresponding enterprise identified the job mark, special operations must be accompanied by the corresponding proof of operation. Users to listen to and respect the installation staff of the views or suggestions to make the installation of the technical conditions are guaranteed, can not be zero when the ground line, can not be in the case of two lines to connect their own ground to the heating pipe, water pipes and other facilities as a grounding , Otherwise it will leave a major security risk.
& Nbsp;
Consumers must carefully understand the instructions, and according to the provisions of the correct use. Daily use, such as the feeling of Ma wind whiz, should immediately stop using, unplug the power plug, please professional maintenance.
& Nbsp;
In addition, in the event of short-circuit fire must not use water to fire, but should immediately cut off the power, or even unplug the power plug or turn off the power gate. In particular, be careful not to hand directly remove the water (water heater, washing machine, electric hot pot, etc.) plug to prevent electric shock. In case someone is electrocuted, should immediately try to cut off the power, unplug the power plug or turn off the power of the total gate, with particular attention can not hand contact with electric shock personnel body or remove the water wire, plug.
& Nbsp;
If you do not use it for a long time, be sure to unplug the power plug of the electric water heater at home.
