1. CAUTIONS

Before installing this water heater,check and confirm that the earthing on the supply socket is reliably grounded. Otherwise, the electrical water heater can not be installed and used. Do not use extension boards. Incorrect installation and use of this electrical water heater may result in serious injuries and loss of property.

Special Cautions

The water heater is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instructions concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the heater. The wall in which the electrical water heater is installed must be able to bear the load more than two times of the heater filled fully with water without distortion and cracks. Otherwise, other strengthening measures must be adopted. The supply socket must be earthed reliably. The installation height of the supply socket must not be lower than 1.8m. The rated current of the socket must not be lower than 16A. The socket and plug must be kept dry to prevent electrical leakage. If the flexible power supply cord is damaged, the special supply cord provided by the manufacturer must be selected, and replaced by the professional maintenance personnel. The maximum inlet water pressure is 0.5MPa; the minimum inlet water pressure is 0.1MPa, if this is necessary for the correct operation of the appliance. When using the heater for the first time (or the first use after maintenance), the heater can not be switched on until it has been filled fully with water. When filling the water, at least one of the outlet valves at the outlet of the heater must be opened to exhaust the air. This valve can be closed after the heater has been filled fully with water. The pressure relief valve attached with the heater must be installed at the cold water inlet of this heater, and make sure it is not exposed in the foggy. The water may be outflowed from pressure relief valve, so the outflow pipe must open wide in the air. In order to drain away the water inside the inner container, it can be drained away from the pressure release valve. Twist the thread screw of the pressure release valve off, and lift the drain handle upwards(See Fig.1) . The drainage pipe connected to the pressure release hole must be kept sloping downwards and in a frost-free environment. The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open to the atmosphere. During heating, there may be drops of water dripping from the pressure release hole of the pressure relief valve, this is a normal phenomenon. The pressure release hole shall not be blocked under no circumstances, otherwise, the heater may get damaged, even resulting in accidents. If there is a large amount of water leak, please contact customer care center for repair. The pressure relief valve need to be checked and cleaned regularly, so as to make sure it will not be blocked. Since the water temperature inside the heater can reach up to 75℃, the hot water must not be exposed to human bodies when it is initially used. Adjust the water temperature to a suitable temperature to avoid scalding. If any parts and components of this electrical water heater are damaged please contact customer care center for repair.

NOTE

Please be sure to use the accessories provided by our company to install this electric water heater. This electric water heater can not be hung on the support until it has been confirmed to be firm and reliable. Otherwise, the electric water heater may drop off from the wall, resulting in damage of the heater, even serious accidents of injury. When determining the locations of the bolt holes, it shall be ensured that there is a clearance not less than 0.2m on the right side of the electric heater, to convenient the maintenance of the heater, if necessary.

4. METHODS OF USING

●

First, open any one of the outlet valves at the outlet of the water heater, then, open the inlet valve. The water heater gets filled with water. When water flows out of the outlet pipe it implies that the heater has been filled fully with water, and the outlet valve can be closed.

NOTE

During normal operation, the inlet valve shall be always kept open.

Insert the supply plug into the socket.

●

If the indicator lights up, the thermostat will automatically control the temperature. When the water

●

temperature inside the heater has reached the set temperature, it will switch off automatically, when the water temperature falls below the set point the heater will be turned on automatically to restore the heating.

(Fig.7)

Rotate the knob according to the marking on the knob to increase or decrease the setting

temperature.

②

The White (up) LED is the power light. The White (down) LED is the heating light. The power light remains ON when machine is connected to power. The heating light will be ON once the knob is rotated to adjust the temperature and will be OFF when the heating process is finished.

5. MAINTENANCE

Do cut off power supply before maintenance, to avoid danger like electric shock.

●

Check the power plug and outlet as often as possible. Secure electrical contact and also proper grounding must be provided. The plug and outlet must not heat excessively.

●

If the heater is not used for a long time, especially in regions with low air temperature(below 0℃), it is necessary to drain water from the heater to prevent damage of the water heater, due to water freezing in the internal tank.(Refer Cautions in this manual for the method to drain away the water from the inner container).

●

To ensure long reliable water heater operation, it is recommended to regularly clean the internal tank and remove deposits on the electric heating element of the water heater, as well as check condition (fully decomposed or not) of the magnesium anode and, if necessary, replace it with a new one in case of full decomposition.Tank cleaning frequency depends on hardness of water located in this territory. Cleaning must be performed by special maintenance services. You can ask the seller for address of the nearest service center.

●

The water heater is equipped with a thermal switch, which cuts off power supply of the heating element upon water overheating or its absence in the water heater. If the water heater is connected to the mains, but water is not heated and the indicator doesn’t light up, then the thermal switch was switched off or not switched on. To reset the water heater to the operating condition, it is necessary to:

1. De-energize the water heater, remove the plate of the side/lower cover.

2. Press the button, located at the center of the thermal switch, see Fig.8;

3. If the button is not pressed and there is no clicking, then you should wait until the thermal switch cools down to the initial temperature.

WARNING

Manual reset button

Non-professionals are not allowed to disassemble the thermal switch to reset. Please contact professionals to maintain. Otherwise our company will not take responsibility if any quality accident happens because of this.
