than 10A. The socket and plug shall be kept dry to prevent electrical leakage. Inspect
frequently whether the plugs contact well with the socket. Inspect method is as follows: insert
the power supply plug into socket, after using for half an hour, shut down the unit and pull the
plug out, and inspect the plug whether it scalds hand. If it scalds (over 50℃), please change
another well-contacted socket to avoid the plug being damaged, fire or other personnel
accidents result from bad-contacting.
The installation height of the supply socket shall not be lower than 1.8m.
The wall in which the electrical water heater is installed shall 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 shall be adopted.
The pressure relief valve attached with the heater must be installed at the cold water inlet of
this heater(see Fig.1), 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; The
pressure relief valve need to be checked and cleaned regularly, so as to make sure it will not
be blocked.
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.

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.
During heating, there may be drops of water dripping from the pressure release hole of the
multifunction valves. This is a normal phenomenon. If there is a large amount of water leak,
please contact customer care center for repair. This pressure release hole shall, under no
circumstances, be blocked; otherwise, the heater may be damaged, even resulting in
accidents.
The drainage pipe connected to the pressure release hole must be kept sloping downwards.
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.
Unscrew the thread screw on the multifunction safety valve, and lift the drain handle upwards.

PRODUCT STRUCTURE FOR VERTICAL
This electrical water heater shall be installed on a solid wall. If the strength of the wall cannot
bear the load equal to two times of the total weight of the heater filled fully with water, it is
then necessary to install a special support.
Incase of hollow bricks wall, ensure to fill it with cement concrete completely.
After selecting a proper location, determine the positions of the two install holes used for
expansion bolts with hook (determined according to the specification of the product you
select). Make two holes in the wall with the corresponding depth by using a chopping bit with
the size matching the expansion bolts attached with the machine, insert the screws, make
the hook upwards, tighten the nuts to fix firmly, and then hang the electric water heater on it
(see Fig.2).
Install the supply socket in the wall. The requirements for the socket are as follows:250V/10A,
single phase, three electrodes. It is recommended to placed the socket on the right above the
heater. The height of the socket to the ground shall not be less than 1.8m.
If the bathroom is too small, the heater can be installed at another place without sun-scorched and
rain-drenched. However, in order to reduce the pipeline heat losses, the installation position of
the heater shall be closed to the location shall be as near as possible to the heater.

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.7;
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.
(Fig.7)
Manual reset button
If the heater is not used for a long time, especially in regions with low air temperature(below 0
℃), it is nessary 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.
