After installation, be sure to ll the
heater completely with water before
switching on the power in the rst
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.
Do not set it at place where is too
cold and may freeze.
Do not use as oorstanding
appliance.
Do not install to places without
sewer.
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 o ered by the
manufacturer.
Do not set at outdoor places.
Please mount it to rm and reliable wall.
In case connecting water heater with
water drain hose, connect the drain
hose to the inlet of the sewer to
avoid polluting by splashing.
Before Usage
Setting Environment
The product adopts the patent "PTO I 0" technology of our company. As long as adopting
civil power supply, even if the earthing wire is electri ed by mistake, the "PTO I 0" technology
still can block the dangerous electricity, and ensure your personal safety. But if you find
perceptible current, please pull o the power plug 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 "PTO I 0". Do not remove it by
yourself.
Otherwise we will not take responsibility for the injure and loss caused by the safety trouble
occurred therefrom.
Do not confuse the water inlet and outlet pipe. The wall bearing the water heater shall be strong
enough to endure a weight twice as much as that of water heater lled with water.
If any part is damaged, please contact the local maintenance agent, and have it replaced with our
spare part.
Be sure to switch o the power supply before cleaning. Use humid cloth with neutral detergent
to wipe the shell gently. Do not use petrol and other solvent. Finally wipe it with dry cloth and
keep the shell dry.
To guarantee the high-e ciency operating of the water heater, please clean the electric heating
pipe and inner tank every three years. Do not damage the protection coating outside the
electric heating element and inside the inner tank. The Magnesium anode rod shall also be
replaced periodically according to the local water quality. Please contact the local maintenance
department for maintenance service.

Packing List
Be sure to have it installed by installation staff of the after service department, or the
appointed sta . It adopts wall-mounting installation.
Make four holes with diameter of 12mm and depth 65mm with churn drill on the wall as
per the installation dimension drawing. Insert the bolts into the holes. Then lift the water
heater, set the wall-mounting rack on the bolt. Set the gasket and fasten the nut. Install the
accessories including safety valve etc. as indicated in Figure 2. Remember to seal with rubber
tape to avoid water leakage.
To facilitate the installation and dismantling, it is suggested to add G 1/2' flexible nut at the
suitable position of the water inlet and outlet pipe separately. Confirm the position needing
water supply. Connect the water inlet/outlet pipe and tap water pipe to the position respectively.
The hot water pipe shall not be too long to reduce the heat losses.
Please reserve some space in installation for the future maintenance.

Please fasten the drain hose to the drain thread of safety valve by
twisting (see to Figure 3). Connect the other end of drain hose to the
sewer to avoid polluting the room by splashing. When the power
is switched on, and the water heater starts operating, there may
be some water discharged from the pressure relief hole of safety
valve. It is due to the water expansion under heating, and is normal
phenomenon. The pressure relief pipe shall communicate with the
air directly. Do not block it. The discharged water can be led to the
sewer. The drain hose connecting to the safety valve shall be kept
downward sloping in installation and in a frost-free environment.
Select suitable position on the wall to x the shower nozzle bearer. Connect the shower nozzle
hose to the pipeline. Fasten the mixing valve. Check if there's water leakage at each joint.
Be sure to check and con rm that the tank is lled with water, there's no leakage at each joint
and the power supply complies with the stipulation before switching on the power.
After installation, as the tank is empty in the rst usage, be sure to open the faucet water inlet
valve and mixing valve. When the tank is lled with water, and the shower nozzle or other
water outlet keeps water outputting, please close the mixing valve, check if there's water
leakage at each joint, and plug the power plug.
Turn the knob as per the needed water temperature. The mark of knob increases from water inlet
temperature to 75°C. You can set heating temperature steplessly. The heating indicator will light
on under heating mode. Generally the knob should be set to the highest scale. The water heater
can regulate the temperature automatically. The power will be switched o automatically when
the set temperature is reached, and will be switched on automatically when the temperature
drops to certain level. As it continues heating, you can use hot water as well.
When the tap water inlet pressure arrives or exceeds 0.75MPa, the drain hose of safety valve
will discharge large amount of water. It is due to extra high water pressure. Please contact the
local after service for disposal.
Heating adjustment can be made exibly all year round adapting to climate changes. In long-
term out-of-use or maintenance, you can close tap water pipe valve and set the mixing valve
to the highest water temperature rate after opening the safety valve handle. Move up safety
valve handle to drain the tank. To avoid injury, before next use, it is suggested to rst open
hot water valve before switching on the water heater, exhausting gas possibly retained in the
pipeline. In this case, no smoke or re is permitted near the open valve. Carefully check and
con rm all parts are in good condition.
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.
This product should work with the safety valve whose rated pressure is 0.75MPa.
The water may drip from the discharge pipe of the pressure relief device and that this pipe
must be left open to the atmosphere. Check safety valve once a month as follow: move the
small handle of safety valve, if there's water owing out, safety valve is normal; if there's no
water ow, 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.
