Before Usage
Setting Environment
The product adopts the patent "Safe Care" technology of our company. As long as adopting civil
power supply, even if the earthing wire is electrified by mistake, the "Safe Care" technology still
can block the dangerous electricity, and ensure your personal safety. But if you find perceptible
current, please disconnect the power and contact local after service department for maintenance.
Do not disassemble by yourself.
The original pipeline of the water heater is an organic part of "Safe Care". Do not remove it by
yourself.
Otherwise we will not take responsibility for the injure and loss caused by the safety trouble
occurred therefrom.
Statement: This water heater shall only be repaired and maintained by qualifie servicemen.
Improper maintenance may cause severe injury or damage. Before opening or
repairing water heater, please do disconnect power supply.
Note: Before asking for service, please refer to troubleshooting section to resolve easy problems.
During installation, adequate space must be reserved for future maintenance and repair. If
the water heater is installed within decoration boards, the right board shall be removable to
facilitate removing the plastic cover during maintenance.
City water inlet pressure shall not be less than 0.05MPa,Maximum pressure can not exceed
0.80MPa.
Electric water heater shall be installed indoors with ambient temperature above 0°C. The pipes
shall be collectively laid. Hot water outlet shall not be too far from use points. In case farer
than 8m, hot water pipe shall have a thermal insulation to minimize heat loss.
The mounting wall shall be firm and reliable to support twice the weight of water heater
full of water. Non-load bearing walls or air brick walls must have corresponding protective
measures like additional support, wall-through screws or back boards.
Electric water heater shall be located in a place easy for use, maintenance and with a floor
drainer. In case the tank or pipes leak, nearby or lower facilities shall not be damaged. The
installation location shall avoid being above toilet bowl, bathtub, washbasin or doorframe,
where will cause a suppressed or unsafe feeling to users.
Power 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.
External Cleaning: Disconnect power supply before cleaning. Gently wipe with wet cloth
dipped with a little of mild detergent. Do not use gasoline or other solvents. Finally dry
with dry cloth. Keep water heater dry. Do not use cleansers containing grinding agent (e.g.
toothpaste), acids, chemical solvents (e.g. alcohol) or polishers to clean.
Internal Cleaning: To ensure high working efficiency, heating elements and tank liner of water
heater shall be cleaned once in three years. Take care not to damage protection layer on
heating elements and tank liner inner surface. According to different local water qualities and
use habits, magnesium rod shall be periodically replaced. If maintenance is needed, please
contact local service station.
For the first use after installation, due to there's no water within the tank, first the city water
inlet valve and mixing valve must be opened. Close the mixing valve when water flows out
continuously from the showerhead or other outlets (the tank is full). Check connections are
free of water leakage, and connect power.
Turn the knob to set your desired water heating temperature, which can be stepless changed
between cold water inlet temperature and 75°C. In heating mode, heating lamp is lighted on.
Normally the knob shall be positioned at highest temperature. This machine has a thermostat
function, which automatically switches off the water heater when temperature reaches the
setting value, and switch on again when water temperature decreases to certain value.
City water pressure
≥
0.80MPa will cause much water flowing out from safety valve pressure
relief vent. This is due to too high water pressure. Please ask after-sales service for correction.
Never do that
Be sure to act as per instructions

Attentions in Operation
Installation must be made by installers of or designated by our company after-service
department. The water heatershall be wall-mounted.
If there is no power cord or plug and the power is not interrupted, the fixing line connected must
be equipped with the all-pole disconnection device provided by breakaway contact under the
overvoltage type III condition according to wiring rules.
Before installation, make sure water heater rear wires are fit firmly. Determine an installation
location. Make four holes
∅
12mm, 65mm deep in the wall with an impact drill according to
installating dimension. Insert fix expansion hooks and expansion bolts in corresponding wall
holes. Lift the water heater. Insert wall rack onto the hooks and bolts. Fit flat washers, rear wires
and nuts in turn onto the bolts (see Figure 2). Tighten the nuts and check them firm. Install
accessories such as safety valve, drain hose as shown in Figure 3. Use sealing compound to
prevent water leakage.
To facilitate installation and removal, it is suggested a G 1/2" movable nut is fitted at appropriate
locations on inlet and outlet pipes respectively. Find water supply location. Connect inlet pipe,
outlet pipe and city water pipe respectively to the use point.
The hot water pipe shall not be too long to reduce the heat losses.
Please reserve some space in installation for the future maintenance.
The safety valve should be connected to the cold water inlet pipe. Please check carefully if the
direction is correct after installation. The correct direction of installation is that the arrowhead on
the safety valve should point to the water heater.
Please connect the drain hose to the safety valve. Connect one end of the hose to the safety valve
vent and the other end to the sewage drain. The hose can be cut short or extended as necessary.
The hose shall be installed as inclined downward. (see to Figure 4)
The water may drip from the discharge pipe of the pressure relied
device and that this pipe must be installed in a continuously downward
direction and in a frost-free environment. Check safety valve once a
month as follow: move the small handle of safety valve, if there's water
flowing out, safety valve is normal; if there's no water flow, please
contact local after-sales service station.
The pressure relief device is to be operated regularly to remove lime
deposits and to verify that it is not blocked.
Before Usage
Safety Precautions
Check if the ammeter and the diameter
of the wires are in accordance with
the rated current of the water heater.
If necessary please have it checked by
experienced electrician.
After installation, be sure to fill the
heater completely with water before
switching on the power in the first
usage. Children must take bath
under the supervision of adult.
In winter of cold area, if the heater is
idle for a long period, please pull the
handle of safety valve to discharge the
water. Otherwise it may freeze inside
the water heater and cause damages.
The product is only available for
alternating current . Be sure to use
independent power and earth it
reliably. Set the power of the water
heater at dry position away from
water spraying.
In opening and closing the water
valve, do not point the shower head
to human body. Otherwise it may
hurt by the spraying hot water.
In case the power cord of the water
heater is damaged, be sure to have it
replaced by after service technicians
with special cord offered by the
manufacturer.

To avoid causing machine troubles, do not connect power before tank is full of water.
Adjust a suitable temperature before use, for water temperature above 50°C may burn your skin.
This product is closed water heater, which can supply hot water through pipe connection to
several points like bathroom (bathtub, washbasin, showerhead) and kitchen.
Heating adjustment can be made flexibly all year round adapting to climate changes. In
long-term out-of-use or maintenance, you can close city water pipe valve, open mixing valve
to hot water range, and move up safety valve handle to drain the tank. To avoid injury, before
next use, it is suggested to first open hot water valve before switching on the water heater,
exhausting gas possibly retained in the pipeline. In this case, no smoke or fire is permitted
near the open valve. Carefully check and confirm all parts are in good condition.
Provided hot water quantity can meet use demand, temperature setting shall be possibly low.
It can minimize heat dissipation, high-temperature corrosion and sedimentation, ensuring a
longer service life.
Regularly ask servicemen to make safety inspection, remove sediment on heating elements,
and check consumption of anode bar. Too much consumed anode bar shall be replaced.
