SAFETY INSTRUCTIONS

●

CAUTION: Risk of injury!

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 supply socket must be earthed reliably. The rated current of the socket shall not

be lower than 16A. The socket and plug shall be kept dry to prevent electrical leakage.

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.

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 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.

During heating, there may be drops of water dripping from the pressure release hole

of the pressure relief valve. 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.

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.

If any parts and components of this electrical water heater are damaged please

contact customer care center for repair.

This appliance 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 instruction 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 appliance.

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.

The water may drip from the discharge pipe of the pressure-relief device and that this

pipe must be left open to the atmosphere; The pressure-relief device is to be operated

regularly to remove lime deposits and to verify that it is not blocked;

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

o, and lift the drain handle upwards.(See Fig.1) A discharge pipe connected to the

pressure-relief device is to be installed in a continuously downward direction and in a

frost-free environment.

QUICK START GUIDE

Fill the inner tank with water before use.

CAUTION

Before First Use

1. Plug in 2. Rotate the thermostat knob

clockwise to adjust the temperature

inside the water heater.

4. Open the water outlet valve, you

can use hot water.

3. When the water temperature reaches

the adjusted temperature, the heating

will be stopped, and the heating indicator

will be o. When the water temperature

drops to a certain temperature, it will

automatically resume heating.

Ground

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).

3. 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 (see Fig.3). If there is fault on power cable, it should be replaced by the

manufacturers, agencies or qualiﬁed person who is able to do this so as to ensure the

safety.

4. 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 dimension of each pipe part is G1/2” ; The massive pressure of inlet should use Pa as

the unit; The minimum pressure of inlet should use Pa as the unit.

Connection of pressure relief valve with the heater on the inlet of the water heater.

In order to avoid leakage when connecting the pipelines, the rubber seal gaskets provided

with the heater must be added at the end of the threads to ensure leak proof joints (see Fig.4).

4. If the users want to realize a multi-way supply system, refer to the method shown in ﬁg.5

for connection of the pipelines.

Pipelines Connection

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 o 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.
