Important 1Safetylnstructions

• The power supply for this water heater is AC 220V/50Hz. Use only a stand-alone power socket. A multi-head socket should not be used. The stand-alone socket must be reliably earthed and manufactured by national quality standards. Clean the metal pins of the plug regularly to prevent fire and other hazards caused by dirt.
• When turning on or off the water heater safety valve, do not direct the spray nozzle at any person to avoid any hurt caused by the initial high-pressure hot water flow.
• When turning on or off the water heater safety valve, do not direct the spray nozzle at any person to avoid any hurt caused by the initial high pressure and hot water flow.
• All damaged cables of the water heater must be replaced by cables specified by the manufacturer. No one should attempt to remove or repair the water heater other than a qualified service technician. Do not place flammable objects near the water heater.
• Use a multi-meter to check the current and ensure that the wire diameter conforms to the rated current of the water heater. If necessary, get a qualified electrician to check.
• Do not use any electrical apparatus that has damaged wiring, loose sockets, or plugs to avoid the occurrence of electrical shocks or fire hazards. Ensure that the water heater plug is properly plugged into the socket.
• When installation of the water heater is done, fill it with water first before turning on the power supply. If the water heater is not filled when power is turned on, the heating element in the water heater will overheat and cause failure. Children who wish to use the water heater should be supervised by adults.
• If the storage water heater is not used for a long time in a cold area, discharge the water inside fully by closing the inlet safety valve and opening the discharge pipe. This is to prevent freezing water from damaging the water heater.

Installation

Installation position

1. The water heater should be installed near a power socket and where there is access to water supply and drainage. Do not install the water heater in places where water discharge is not possible.
2. During installation, both the water inlet and outlet pipes must be at the bottom of the water heater. The water heater cannot be installed vertically.
3. The mounting wall for the water heater must be firm and solid, and able to bear at least twice (2 times) the total combined weight of the water heater and the filled water within.

Installation of water heater body

1. Drill two (2) holes of 12mm diameter into the wall. The two holes must be along the same horizontal line as shown in Fig. 3.
2. Insert an expansion bolt into the hole and tighten the hook. Ensure that the hook faces upwards.
3. Lift the water heater and place it to rest firmly on the hooks.
4. Tapping screws are used to fasten the decorating strip in place.

Water pipe connection

1. Seal the water discharge pipe of the water heater with a plug and gasket to prevent water leakage after installation.
2. Screw in the safety valve at the water inlet pipe. The pressure relief port of the safety valve should point downwards. The safety valve can only be installed at the water inlet pipe of the water heater.
3. If the electric water heater is used with a mixing valve, install the filter at the water inlet. Then connect to the safety valve. After that, connect one end of the water mixing valve to the water outlet pipe of the water heater and the other end to the water inlet of the safety valve. Connect the spray nozzle via the hose to the outlet of the water mixing valve. Finally, connect the tap water to the water inlet of the water mixing valve (Fig. 5A).
4. To fill with water, first turn on the discharging tap behind the water outlet pipe of the water heater (rotate the handle to a high-temperature position if a water mixing valve is installed). Then turn on the water inlet valve. The water will begin to fill the water heater. When water begins to come out from the discharging tap, this means that the water heater is filled. Turn off the water discharging tap (or rotate the handle of the water mixing valve to the closed position). Ensure that each connection is well sealed to prevent water leakage.
5. If the water heater is used with a centralized water supply, determine the place that requires hot water and connect the water outlet pipe and tap water inlet as shown in Fig. 5B.

Note:

1. The water inlet valve must always be open under normal operation.
2. The water pipe and hot water outlet pipe of the water heater (when embedded in the wall) must be of a hard metal pipe with a pressure resistance equal to or more than 0.8 MPa (8 Bar) with a temperature resistance equal to or more than 1 OO”C. Do not use PVC pipes or hoses which are not pressure-resistant.
3. Ensure that the water inlet and water outlets are correctly identified (Fig. 5A)

Power supply connection

1. Use only a single-phase AC 220V, 50Hz power supply for this water heater. Please check carefully the rated current of the water heater to ensure that it conforms to the supplied current.
2. Use only a 3-pin stand-alone power socket equal to or more than 15N220V that is reliably earthed. Do not use a multi-head socket. The socket must conform to national quality standards. The connecting cable must also conform to rated current requirements. The metal pin of the plugs should be regularly cleaned to prevent fire or other hazards caused by dirt. If the water heater has a power of 1500W, it may use a power socket rated 1 ON220V.
3. The outlet socket must have a reliable earth wire. It is recommended that an electric leakage switch (fuse) be installed within its circuit.

Warning:

1. Do not use any electrical apparatus that has damaged wiring, loose sockets, or plugs to avoid electric shocks, short circuits, or fire hazards. Check that the plug is firmly attached to the power socket.
2. Check that the plug of the water heater is not near any wet areas or prone to water sprays. Do not unplug when hands are wet to avoid electric shocks.
3. Do not turn on the power supply to the water heater until the heater is filled with water. This is to prevent dry burning.
4. The discharging point of the safety valve should be we/I-ventilated. During heating of water, the water inlet valve must be tum on to prevent cracking of the inner tank.

Operation

1. Power on
   Before turning on the power supply, check to make sure that the water heater is filled with water. The water inlet valve must be turned on during normal operation. When it is confirmed that the water heater is filled with water, connect the plug to the outlet socket. The ECLB indicator light (green) will light up to show that power is supplied. Press the test button to automatically turn off the power supply and the ELCB indicator light (green) will go off. Press the reset button again and the ELCB indicator light (green) will come on again. The water heater is now in normal operation mode.

2. Water temperature control
   To set the water temperature, turn the temperature control knob until the power indicator light (red) is on. This means that the water is heating up. Then rotate the knob to your desired position, the water temperature can be freely adjusted within its temperature range.

3. Automatic temperature regulation control
   When the water temperature reaches a preset value, the power indicator light (red) will go off. The light will turn on again when the water temperature goes below the preset value.

4. Excessive temperature and dry burning protection
   If the automatic temperature regulator control is not functioning properly, the excessive temperature device will immediately cut the power supply to the electrical heating element. Please contact your local service agent to rectify the problem.

5. Excessive pressure protection
   When the pressure inside the water heater is more than the rated pressure of its inner tank, (0.8 Mpa / 8 Bar) a safety valve will relieve the pressure automatically.

6. Hot water application
   To use hot water, turn on the cold water valve and slowly rotate the water mixing valve to let cold water flow out first. As the water mixing valve is gradually turned up, the water temperature will increase to the required temperature setting. Finally, turn off the cold water valve to prevent scalding.

7. Long-term usage
   If the water heater is unlikely to be used for a long period, unplug the heater from the power outlet socket.

8. Power optional operation (multi-power series function)
   The heating element of the water heater is twin type, so the customer can select power by turning on or off the switch.

Electrical leakage test

1. Electrical leakages should be tested during normal operation. Press the test button to check for leakages. If the power supply can be disconnected with the test button, the ELCB indicator light will go off to signify that the electrical leakage protection is functioning. Press the reset button and continue to use it.
2. However, if during normal operation, the ELCB indicator light is always off or does not turn off even after pressing the test button, the water heater may have experienced electrical failure. Please contact your local service agent for repair and maintenance. Do not attempt to fix the problem personally.
3. If the power supply has tripped or power is disconnected during normal operation, press the reset button. If the ELCB indicator light comes back on, the water heater can be used as normal. If the power indicator light does not light up, please check the power socket to see if the socket is damaged due to frequent use or disconnected when the excessive temperature protection is activated.
4. Reset is not possible if the electrical leakage failure is not rectified.

Service and Maintenance

• Unplug the water heater before service, maintenance, and inspection.
• Ensure that water will not enter the water heater during cleaning.
• Clean with a soft towel dipped in water.
• Do not use detergents that contain abrasive powder (eg toothpaste), acid, chemical agents (eg alcohol), or polishing compounds.
• As water has small impurities and minerals, the bottom of the water tank will always have some sediments after long-term usage. Empty the water periodically to discharge the sediments. Meanwhile, clean the electric heating element and remove water scaling gathered on the element and at the bottom of the tank.
• In general, water should be emptied once a year or more often if water is of poor quality.
• The magnesium anode rod must be replaced once every two years. Please contact your local service agent for any replacement.
• The replacement period for magnesium anode rods varies according to conditions and operations. The harder the water, the shorter will be the period.
• To test the safety valve close the water inlet valve, open the mixing valve, and adjust to the highest temperature. Then lift the handle of the safety valve to let the water flow out of the pressure relief port of the safety valve until it discharges completely. You can also remove the mixing valve and safety valve and let the water discharge directly from the water inlet.
