Installation precautions

1. In order to prevent the occurrence of accidents, you must install the accessories provided by our company and shall not replace or replace them by yourself. If the accessories are damaged, you must inform the maintenance department of our company to repair and replace them with the accessories provided by our company.
2. Water heater should be installed indoors. Do not install the water heater in an icy environment below 0°C. Icing may break containers and water pipes, resulting in burns and water leakage. Piping should be centrally arranged, and the hot water outlet should not be too far away from the hot water use point. If the distance is more than 8m, the hot water pipe should be insulated to reduce heat loss.
3. When installing the water heater, a certain space should be reserved (at least 300mm on the right side) for the convenience of future maintenance. If the water heater is installed in the gusset, the right gusset should be movable to facilitate removal of the plastic cover during maintenance.
4. The installation location of the water heater should be convenient for use, maintenance and floor drain. In case of tank or pipe leakage, no damage will be caused to nearby or lower facilities. Try to avoid installation in the toilet, bathtub, wash basin, door frame above, so as not to let the user produce depression or insecurity.
5. The wall of the water heater should be solid and firm, and can bear the weight of the water heater after being filled with 4 times more water. For non-load-bearing walls or hollow brick walls, appropriate protective measures must be taken, such as installing supports, using through-wall screws, installing backboards, etc.
6. Do not reverse the inlet and outlet water pipes. The safety valve should be installed according to the specified position, and can not be changed without permission. The pressure relief hole of the safety valve should be kept communicated with the atmosphere, do not plug it.
7. Ensure that the tap water inlet pressure is not less than 0.05MPa, the maximum pressure is not more than 0.75MPa.
8. The power socket of the water heater should be installed in a dry place that will not be wet with water, and it is best to have a waterproof box so as not to affect the normal operation of the machine.
9. The water heater should be used in line with the national standard of the independent socket, and reliable grounding, with the measuring pen to measure the live wire, neutral wire is connected correctly. Do not use multifunctional sockets.

Precautions for use

1. Do not switch on the power supply before the water heater is filled, so as not to damage the machine.
2. Hot water above 50^ C may cause scald. Please be sure to adjust the water temperature to the appropriate temperature before your family, especially children, use it.
3. In the case of sufficient hot water, to lower the set temperature as far as possible, so as to reduce heat loss, high temperature corrosion and scaling, prolong the service life of the water heater.
4. This water heater is closed and can supply water to many places through the pipeline, such as: bathroom bathtub, bathroom nozzle, kitchen.
5. Please do not put gasoline and other flammable materials near the water heater, otherwise it may cause fire and other accidents.
6. It is normal for the water heater to produce white turbid water. This is because the dissolved air in the water expands with heat and the pressure decreases, so it spills out and produces bubbles (similar to beer foam), which is pollution-free and harmless.
7. The electric water heater will produce sound in the process of high temperature heating, just like our commonly used hot kettle, it is a normal phenomenon, please rest assured to use.

This is just the machine installation diagram, the specifics subject to the actual machine!

1. Installation must be carried out by the installation personnel of the company's after-sales department or its designated installation personnel.
2. The water heater is mounted on the wall.
3. Determine the installation position of the water heater. According to the size shown in Figure 1, drill two holes on the wall for matching the expansion hook of the attachment with a hammer drill, insert the expansion hook into the corresponding wall hole, and fix it.
4. Lift the water heater and put the wall rack on the hook. Install the safety valve and other accessories by referring to "Installing the safety valve" (for installation reference only). Be careful to seal with PTFE tape to prevent water leakage. Note: Different machines correspond to different wall brackets, installers can refer to the actual drilling of the bracket installation.
5. To facilitate the installation and disassembly of the water heater, it is recommended to install G1/2 loose joints at appropriate positions of the water heater inlet and outlet pipes. Determine the location of the water supply, and connect the inlet and outlet water pipes and the inlet water pipes to the water points respectively. Fill the liner with water, check whether the water is leaking and reconnect if there is water leakage.
   Note: 1. Be sure that the wall bracket is reliably hung on the hook before letting go, in case the water heater falls, causing personal injury or property damage.
6. The two holes in the hanging frame can ensure the safe installation of the machine.

Installing the safety valve:

• Install the G1/2 valve on the water inlet pipe by referring to the direction of the arrow on the valve (thearrow points to the water flow direction).

Pressure relief holes should be kept open to

• theatmosphere, do not block it.

When the water heater is heated by electricity,

- therewill be a small amount of water droplets coming out of the pressure relief hole of the safety valve. This is due to the expansion of the water tank by heat and is a normal phenomenon.

Instructions for use

After installation, the water inlet valve and water outlet valve must be opened for the first time because there is no water in the tank, and the water outlet valve must be adjusted to the maximum hot water gear. When the hot water outlet is continuously discharged (indicating that the water in the container is full at this time), close the outlet valve. Check each interface without leakage and then turn on the power.

How to use

1. Adjust the water temperature knob on the right side of the water heater to set the water temperature

2. The maximum water temperature can be set to 75^ C

3. Rotate the temperature control knob clockwise, the set temperature will gradually increase, when the setting reaches the highest temperature, the knob will not continue to rotate;
4. Turn the temperature control knob counterclockwise, the set temperature will gradually decrease, when the setting reaches the lowest temperature, if you continue to turn the knob, the power will be cut off.
5. When the heating indicator light is on, the water heater is heating. When the heating indicator light is off, the heating is completed and the water heater is in the holding state.
6. When the water temperature reaches the set temperature, the power will be automatically-turned off, and when the water temperature drops to a certain temperature, the power will be automatically turned on to continue heating.

OFF MAX HEATING Water temperature knob Heating indicator light

The water temperature knob and heating indicator are shown in the figure above. For the specific machine, please refer to the actual object

1. Observe the thermometer to know the current water temperature zone

Thermometer pointer in the low temperature zone (left) : indicates that the tank water temperature is low

Thermometer pointer in the high temperature zone (right) : indicates that the tank water temperature is high

1. Observe the drainage of the pressure relief hole of the safety valve

- When the tap water pressure is ≥ 0.8MPa , there will be a large amount of water flowing out of the safety valve relief hole, which means that the water pressure is too high, and the after-sales service should be notified to deal with it.

Cleaning and Maintenance

NOTE: This water heater should only be serviced by qualified service personnel. Improper handling may cause serious injury or property damage.

Be sure to unplug the water heater before cleaning and servicing it.

Cleaning

1. External cleaning

Gently wipe with a damp cloth dipped in a small amount of neutral cleaning agent, do not use gasoline or other solutions. Finally, dry with a dry cloth to keep the water heater dry. Be careful not to scrub with cleaners that contain abrasives (such as toothpaste), acids, chemical solvents (such as alcohol), or polish agents.

2. Internal cleaning

• The power must be turned off before cleaning the tank.
• When cleaning, close the water inlet valve, open the water outlet valve, remove the safety valve at the cold water inlet, drain the water in the tank, then open the water inlet valve and rinse repeatedly for a few minutes until the net water is discharged.

Safety check

• Check the safety valve once a month: pull the small handle of the safety valve. If water flows out, it indicates that the safety valve is working properly. If no water flows out, please contact the after-sales service department of Haier to repair or replace it.
• Regular safety checks should be conducted by professional personnel. Remove scale of heating pipe in time and replace magnesium rod.

■ Prolonged non-use

If you need to disable the water heater for a long time, follow this step:

1. Close the tap water valve.
2. Open the safety valve handle.
3. Open the hot water valve of the water heater to the maximum (if there are multiple hot water outlets, it is recommended to open all to the maximum. Please note that you will not be scalded by hot water at this time) and discharge the water in the tank. Note: Some buried wall pipes cannot be discharged by users. Therefore, open the loose connection at the water outlet.
   When using again, in order to avoid injury accidents, it is recommended to open the hot water valve before opening the power switch of the water heater, to discharge the gas that may exist in the pipeline from the pipeline. At this time, no smoking or other open flame is allowed near the open valve. At the same time, it is necessary to carefully check whether all parts of the water heater are in good condition and confirm that the tank is full of water before it can be put into use.
