Precautions during installation
City water inlet pressure shall not be less than
0.05 MPa.
Electric water heater shall be installed indoors
with ambient temperature above 0℃. The pipes
shall be collectively laid. Hot water outlet shall
not be too far from use points. In case farer than
8 m, hot water pipe shall have a thermal
insulation to minimize heat loss.
Electric water heater shall be located in a place
easy for use, maintenance and with a fl oor
drainer. In case the tank or pipes leak, nearby or
lower facilities shall not be damaged.
Power socket for water heater shall be in a dry
place free of water splash. (splash-proof box is
preferred).
Do not confuse inlet and outlet water pipes.
Safety valve shall be installed at designated
position with no random modification.
Precautions during use
1
To avoid damage, never turn on the power before the inner tank is fully filled with water.
2
To avoid scalding, adjust the water temperature to an appropriate degree before use. Water
over 50℃ can result in scalding.
3
The relief valve should be checked once every two weeks during use. The method: turn the
small handle of the relief valve. It is normal if there is water fl owing from it. If not, please
contact local after-sales service center.
4
The product is a water heater of enclosed type. It can supply hot water to several locations
such as bathroom (bathtub, hand wash basin, shower nozzle) and kitchen.
5
If the water heater is not to be used for an extended period or if it is to be repaired, please
turn off the inlet valve and turn on the relief valve to relieve pressure. Then, open the water
outlet and blowdown port to drain the water in the inner tank. Before reusing, to avoid injury
or accidents, it is recommended to turn on the hot water valve before turning on the power
of the water heater. In this way you can discharge air in the pipeline. At this time, please do
not smoke or light other open fl ames near the open valve. Meanwhile, carefully check that
all the components of the water heater are in good condition. It can be put into use after all
of these are confirmed. Note: the other end of the drain hose may not be higher than the
pressure relief hole of the relief valve. The drain hose should be inserted into the fl oor drain
or other places to facilitate draining.
6
Please ask a service person to conduct safety examinations regularly. Remove the scale on the
heating element in time. Check the consumption of the magnesium anode rod and replace it
in a timely manner if it is too seriously worn.
7
Please don't put the infl ammable substance, such as gasoline and so on, near the water
heater, or else it may cause fire or other accidents.
Using method
In initial use after installation, it must be fully filled with water before turning on the power.
In first use, as the inner tank is empty, you must turn on the tap and one of the water outlets.
Wait until water comes out continuously (it indicates the tank is full) and then turn off the
water outlet.
Check all the joints for leakage. After that, plug in the power cord.
The rated temperature of the water heater is 75℃. The indicator lamps will illuminate in
heating state. When it reaches the rated temperature, the power will be turned off and the
indicator lamps will go out.
Large amount of water will come out from the drain hose of the relief valve if the pressure of
the tap water is higher than 0.7MPa. This is caused by overly high water pressure. Please call
the after-sales service center. Water or vapor will come from the drain hose of the relief valve
if the temperature of water inside the inner tank exceeds 99
by relieving pressure as the temperature is too high. Please call the after-sales service center
in this case. Please keep away from the drain hose during use to avoid scalding.

Installation methods
Be sure to have it installed by the installation staff from the after-sales service center of the
manufacturer or a center authorized by them. It adopts fl oorstanding installation.
Locate the water heater and install all the pipes with a tap water tube (PP-R pipe is recommended)
according to the dimension diagram and the user's requirements. Mount the relief valve and
other accessories according to Fig. 2. Remember to use Tefl on seal tape to avoid leakage.
To facilitate installation and dismantling of the water heater, it is recommended to fit a G1/2"
fl exible nut at the suitable location on the water inlet pipe and outlet pipe separately. Confirm
the positions needing water supply and connect the water inlet pipe, outlet pipes and tap water
pipes to the locations separately.
Note: The hot water pipe shall not be too long to reduce the heat losses.
When installing the water heater, please reserve certain space to facilitate future maintenance
and repair. Fig. 2 is only a reference installation schematic of pipelines. In specific installations, the
actual situation of the user should be considered.
Connection and use of the check valve:
Connect the check valve with G1/2" connection screw according to the arrow on it.
Connection and use of safety valve:
Mount the relief valve on the water heater with position as shown in Fig. 2. Fit the double nipple in the relief
hole of the relief valve and then screw one end of the drain hose onto the double nipple (as shown on Fig. 3).
When the water heater is powered on, a small amount of water may drip out of the drain hose. This is a normal
phenomenon caused by expansion of water inside the water heater. The relief hole must be kept unblocked.
The drain hose can be cut short or extended as necessary. Connect the other end of the drain hose to the
sewage drain to avoid polluting by splashing. The drain hose connecting the relief valve should be installed in a
continuous downward direction and in a frost-free environment.
Be sure to check and confirm that the tank is fully filled with water, that there is no leakage from any joints, and
that the power supply complies with the requirements before switching on the power.

Cleaning and maintenance

Note:
Please deal with simple issues by referring to the attached "FAQ" before calling a
service person.
Statement: Maintenance or repair work can only be performed by qualified service persons.
Improper methods may cause serious accidents or property damage. Make sure
to unplug the water heater before you intend to open the water heater or repair it.
To clean the outside: Disconnect the power supply before cleaning the water heater. Wipe it
lightly with a piece of wet cloth dipped in a little neutral detergent other than gasoline or other
solutions. Then, wipe it with a piece of dry cloth and keep the shell dry. Do not clean it with
detergent containing abrasives (e.g. toothpaste), acid, chemical solvents (e.g. alcohol) or polish.
To clean the inside: To keep the water heater working efficiently, the heating elements and the
inner tank should be cleaned once every three years. Take care not to damage the protection
coating outside the heating element and inside the inner tank. The magnesium anode rod
should be replaced periodically according to local water quality and the using habits.
To clean the inner tank: Blowdown procedure: disconnect the power supply, turn off the
inlet valve and turn on the relief valve to relieve pressure. When no water comes from it,
turn off all the water outlet valves. Remove the drain hose of the relief valve together with
the double nipple. Then, unscrew the blowdown nut. Connect the drain hose with double
nipple on the blowdown port (put the other end of the drain hose in the sewer inlet). Turn
on any one of the water outlets to conduct blowdown. Clean water coming out of the
drain hose indicates the dirt in the inner tank has been totally discharged. Install all the
components in their original places. Note: the water inlet valve should be turned on several
times to rinse the dirt at the bottom of the inner tank during blowdown.
Special hints
Be sure to disconnect the power supply before performing any maintenance or repair work
on it. Only professionals should be allowed to adjust or repair the water.
Make sure the water heater is fully filled with water before turning on the power. Otherwise
malfunction of the heating element may occur. Please make sure the power socket complies
with applicable national standards and is reliably grounded. Never use the water heater
without reliable earthing.
The water heater is fitted with a relief valve. To ensure safety, please do not change its
installation location and never block its outlet.
When the ambient temperature is under 0℃, the piping may be damaged due to freezing
of water in it and cause the water heater to malfunction. So you shall drain the water in the
tank to avoid freezing. If the water heater is not to be used for a period of over 1 month,
please unplug the power cord and drain the water tank.
If the electrical water heater is seriously soaked with water, it must be examined and repaired
by a technician authorized by the manufacturer before it is put into use again.
Scale can be formed in the water tank after long periods of use. Besides, water quality may
change due to ageing of the water pipe. After you wash rice or vegetables with water from
the water heater, please rinse them with clean tap water.
Do not place fl ammables such as gasoline near the water heater to avoid fire or other
accidents.
