Safety warning (Read carefully before use)
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 
an experienced electrician.
This water heater is available for AC 
230V/50Hz power.

heater at the dry position away from 
spraying water. Do not plug/unplug 
with wet hands.
After installation, be sure to f ill the 
heater completely with water before 
switching on the power in the f irst 
usage. Children must take a bath 
under the supervision of adult.
In opening and closing the water 
valve, do not point the showerhead 
toward the human body. Otherwise 
it may hurt by the spraying hot water.
During winter in a cold area, if the heater 
dle for a long period, please pull the 
is i 
handle of the safety valve to discharge the 
water. Otherwise it may freeze inside the 
water heater and cause damage.

Installation • Usage
Installation
Installation must be made by installers of, or designated by, our company after-service 
department. The water heater shall be wall-mounted.
Make 2 holes Φ12mm, 65mm deep in wall with an impact drill according to the drawing of 
the external dimensions.  
Take out all accessories in packaging liner, unpack one hook, sleeve the ring end of the 
connection lines among the accessories into the hook tightening end and assemble the hook 
well. Afterwards, insert and f 
lines is f ixed in the right hole). Lift the water heater and hang it with wall rack corresponding to 
the two hooks. insert the connection spacer led from the rear shell wall rack of the heater into 
the connection terminal of the line on the hook (See Figure 2). Install accessories such as safety 
valve as shown in Figure 3. Do use sealing compound to prevent water leakage.
To facilitate installation and removal, it is suggested a G1/2 movable nut be f 
locations on inlet and outlet pipes respectively. Find the location requiring hot water supply. 
Connect inlet pipe, outlet pipe and city water pipe respectively to the use point for hot water. 
Note: The hot water pipe shall not be too long to reduce heat losses.
Please reserve some space in installation for the future maintenance.

Connection and use of safety valve
The safety valve should be connected to the 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 for fear of indoor contamination. The hose 
can be cut short or extended as necessary. The hose shall be installed as inclined downward.
The heater should work with the safety valve whose rated pressure is 0.80MPa.
During heating, water may drip from the drain hose of the pressure relief hole due to 
expansion and the hole must be left open to the atmosphere. Check safety valve once a 
The pressure relief hole is to be operated regularly to remove lime deposits and to verify that it is not blocked.
Attention during installation
Please fasten the drain hose to the pressure relief hole of the safety valve by twisting (see to 
Figure 4). 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 the safety valve. It is due to the 
water expansion under heating, and is a normal phenomenon. The pressure relief pipe shall 
communicate with the air directly. Do not block it. The drain hose connecting to the safety 
valve shall be kept downward sloping in installation and in a frost-free environment.
Be sure to check and conf irm that the tank is f illed with 
water, there is no leakage at each joint and the power supply 
complies with the stipulation before switching on the power.
This heater must be equipped with the safety valve along 
with the machine; otherwise any safety accident and property 
loss caused thereby shall be the user's own responsibility.

hose
(Figure 4)
Safety precautions
Do not confuse the water inlet and outlet pipes. The wall bearing the water heater shall be strong 
enough to endure a weight twice as much as that of a water heater f illed with water. Do not secure it 
by means of adhesive or similar products because the f ixation by such methods is unreliable.

To avoid danger caused by accidental resetting of the heating breaker, the power for the heat 
cannot be supplied by timer and other external switch devices or connected to circuit with 
frequent switching for facility use.
If any part is damaged, please contact the local maintenance agent and have it replaced with 
our spare parts.
 Tap water inlet pressure shall be no less than 0.05MPa and the maximum pressure shall not 
exceed 0.75MPa.
Usage
After installation, as the tank is empty in the f irst usage, be sure to open the tap water inlet 
valve and turn to the top temperature button on the mixing valve. When the tank is f illed 
with water, and the shower nozzle or other water outlet keeps the water output, please close 
the mixing valve, check if there is water leakage at each joint and plug the power.
Turn the knob as per the needed water temperature. The setting temperature rises gradually 
when the temperature regulating knob is rotated clockwise; when setting to the maximum 
temperature, the knob cannot be rotated any more; the temperature decreases gradually in 
case of anticlockwise rotation of the knob. The mark of the knob increases from the actual 
temperature to 75 
will light on under heatin
o
C. You can set the heating temperature steplessly. The heating indicator 
g mode. Generally, the knob should be set to the highest scale. The 
automatically when the set temperature is reached, and will be switched on automatically when 
the temperature drops to a certain level. As it continues heating, you can use hot water as well.
When the tap water inlet pressure arrives at or exceeds 0.80MPa, the drain hose of safety 
valve will discharge a large amount of water. It is due to extra high water pressure. Please 
contact the local after service agent for disposal.
In long-term out-of-use or maintenance of the heater, you can close the city water pipe valve 
and set the mixing valve to the highest water temperature rate after opening the safety valve 
handle. Move up the safety valve handle to drain the tank. To avoid injury, before the next 
use, it is suggested to f
irst open hot water valve before switching on the water heater, exhaust 
gas possibly retained in the pipeline. In this case, no smoke or f ire is permitted near the open 
valve. Carefully check and conf irm all parts are in good condition.
