The installation and badness of the electrical appliances, lightly affect the comfort of the use, and the severe consequences are caused.Therefore, on the installation of electric water heaters, owners must attach great importance to learning how to install electric water heaters to avoid unnecessary trouble in their own negligence.
Compel
Failure phenomenon 1: Power leakage protection electrical source line sticks and cannot be reset
Cause analysis: ① Ultra -temperature protector jump ② Circuit component leakage ③ Leakage protection plugs Bad
Maintenance method:
① First check whether the ultra -temperature protector and the thermostat jump, the power -on and power -on, check whether the leakage switch can be reset, whether the water heater can work normally, or remove the ultra -temperature protector and thermostat with a multimeter to measure the interruption.Whether it is normal, if it is normal, it can be judged that the temperature setting of the ultra -temperature protector or the temperature controller changes and needs to be replaced.In order to avoid the same failure of the same failure, it is best to replace the super temperature protector and the temperature controller and return the company to detect them by special instruments.
② Check whether there is damage to the insulation layer inside the water heater and cause short -circuit leakage. Unplug the connection line of the electric heating pipe and the indicator light.Detecting whether each device is normal by the component detection method is normal.
③ Check the leakage protection power cord, remove the connection end of the leakage protection power cord, pay attention to the non -touch contact of each line, insert the power supply, press the leakage switch to reset the reset. If it cannot be resetThe leakage device is bad and needs to be replaced.
Failure phenomenon 2: The indicator of the power line of the leakage protection power cord is bright, the water heater power indicator is not bright, and there is no hot water
Cause analysis: ① Whether the thermostat has been opened ② Whether the connection is loose or broken ③ whether the working voltage of each component is normal?
Maintenance method:
① Check whether the thermostat temperature knob is adjusted to the highest temperature position.
② Check whether the power cord and the connection cable are loose or disconnected.
③ Use a multimeter AC250V file to measure the power cord, the connection line and the component whether there is a normal operating voltage of 220V.
Failure phenomenon 3: The indicator of the leakage protection power cord is bright, the water heater indicator is not bright, and there is hot water
Reason analysis: ① The temperature controller has been insulated
② Whether the power indicator light line is connected well
③ Whether the indicator light voltage is normal
Maintenance method:
① Check whether the thermostat has been kept insulation, and release the hot water for about 5 minutes to check whether the indicator light is on.
② Check whether the connection of the indicator light is connected well, whether it is loose and disconnected
③ Check the voltage of 220V in the indicator light. Use the survey indicator light red and the blue wire plug -in with 220V voltage. If the voltage is available, but the indicator light is not bright, it is determined that the indicator light has been burned out and needs to be replaced.
Failure phenomenon 4: The water heater power supply indicator is bright, no hot water
Cause Analysis:
① The water outlet pipe of the mixed water valve is blocked
② Electric heating pipe connection plug off and break off and break
③ There is no working voltage in the electric heating pipe
④ Burning of the electric heating pipe
Maintenance method:
① Touch the water out of the water out of the water mixing valve to get the water out of the water, whether the heating time is too short, and the water pipe is unscrewed.
② Check whether the electric heating pipe connection plug is loose and disconnected, and use a multimeter to measure the connection line.
③ Check whether there is a working voltage of 220V in the electric heating pipe, and measure the two -terminal and connection line of the electric heating pipe with a multimeter AC250V file.
④ Check whether the electric heating tube burns the heat wire, and use the multimeter to detect whether the electric heating pipe is normal according to the component detection method.
Use maintenance
1. When water injection, open the outlet to open the water outlet, wait for the air in the inner biliary to completely rule out whether the water is filled with water;
2. Before the water injection air, the protection measures such as cutting off power should be taken;
3. When installing a closed installation, the water inlet valve must be opened during heating;
4. When the water valve just opened, do not give the outlet to people, otherwise the high -temperature hot water generated may hurt people.
The electric water heater has been used for a long time, and the user does not have timely cleaning the inner bilots of the water heater, which may cause the scale in the heating pipe to be severe. The heat heating of the electric heating tube during use is insufficient, and of course the water temperature increases slowly, which affects normal use.Electric water heaters should be maintained once a year. This can avoid problems such as deformation and rupture of water pipes for long use.
Electric water heater installation
1. When trying the first trial, the first should be passed first and then power, otherwise the consequences are that the heating experience inside will be burned instantly.
2. Electric water heaters have high requirements for wires, contacts, and meters, so the installation of electricity is very important.Because the electric water heater is a high -power electrical appliance, it is necessary to look at the size of the entrance line during installation. Generally, the entrance line is from ten square meters to sixteen square meters. Therefore, there is basically no problem with the entrance line.The lines from the distribution box to the bathroom must be prepared in advance, and the special line of at least 4 square meters should be arranged.
3. The leakage protection device generally requires that the power supply can be quickly cut off within 0.1 seconds when the leakage current reaches 15 horsepower.Therefore, it is a product with a product with the Great Wall Safety Logo, or the product designated by the manufacturer, because the manufacturer knows more about the safety performance of the product.
4. The problem of air switch.The power distribution box will be designed in advance in the current house structure. There is a total gate, and then divides the gate. One route is controlled. The total gate is 40A or 60A. The installation of this device generally does not affect any problems.High safety.
5. Safety guarantee is higher.Generally, the power leakage protection device must instantly cut off the power when the leakage current reaches 15 horsepower.Therefore, consumers should buy products with Great Wall Security Labies or products designated by manufacturers.
6. Install the meter and consider it.Do not be less than 20A when installing a meter. It is best to use a meter of 30A ~ 40A, because the family also uses other high -power electrical appliances such as air -conditioning in addition to the water heater, which is also convenient for other electrical appliances to use in the future.
7. Easy to install with water pipes.If the water heater is mainly used in the shower room, you can directly connect the shower interface to the electric water heater hot water outlet, which is not only convenient and safe, but also reduces the loss of heat.Shower should use high -grade materials. No one is prone to leakage, or it is best to use the manufacturers designated and original shower.
