Caution
Note:
Failure to follow this manual means the risk of accident, property loss and personal injury.
The water heater must be repaired or maintained by qualified professional personnel.
Improper operation may cause serious personal injury or property loss.
In case of any abnormality or scorching smell of
the water heater, please cut off the power supply
immediately and contact the service center.

(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

Caution
Caution
In order to ensure safety, the power supply of the water
heater should be reliably earthed, otherwise, it is strictly
prohibited to use the water heater. The test pencil should
be used to determine whether the live wire and the
neutral wire are connected reversely.
switch matched with the water heater must be used
Do not touch the power supply with wet hands, so as
to prevent it from getting wet by water. If it is wet by
accident, it must be inspected and confirmed by the
professional personnel appointed by our company
before reuse to prevent electric shock.
Make sure to use an independent power supply．
This appliance is not to be used for a potable water
supply.

Installation guide
Precautions for installation
1.The load-bearing wall for installing the water heater should be able to bear twice the weight of the water
heater filled with water.
2.The water heater should be installed indoors and in a non-icing place, with pipes arranged centrally.The hot
water outlet should not be too far away from the hot water use point. If the distance exceeds 2m,the hot water
pipe should be insulated to reduce heat loss.
3.The water heater should be installed in a place that is convenient for use and maintenance and has a sewer
to ensure that surrounding or lower facilities cannot be damaged when water heater or water pipe leaks. Please
do not install the water heater in a place that can be sprayed directly or is prone to icing.
4. Because of the high power of this water heater, before installing the water heater, please carefully check
whether the ammeter and power wire diameters (2.5mm
2recommended) and fuse meet the rated current and
voltage requirements of this water heater. If necessary, please ask a professional electrician to check the circuit.
5. Do not connect the water-in and water-out pipes reversely; Under no circumstances should the outlet be
blocked.
6. To ensure safety, the water heater should use the standard single-phase bipolar air switch or circuit breaker
(in the case of circuit breaking, the open distance of all contacts should be at least 3mm so as to reliably cut off
the connection with the external power supply during maintenance), and be earthed reliably, with the earthing
resistance of the household earth wire less than 4Ω. Because the water heater requires a large current,the
incoming power supply of the water heater must be directly connected with the air switch, and the power plug
should not be used.
7. The test pencil should be used to determine whether the live wire and the neutral wire are connected
reversely.
8. The outlet must not be connected to any tap or fitting other than those specified.
9. The water heater is equipped with the flow control valve. For use safety, the flow control valve should be
installed on the water-in pipe, and it is strictly forbidden to install the valve at the outlet of the water heater.
10.The water inlet of this appliance shall not be connected to inlet water obtained from any other water heating
system.
11.Metallic / chromed hose and conductive control valve shall not be used!
2.Remove the power cord
plug of the rear shell.
Installation of whole machine
1.Remove the front shell
screws and the front shell.
3. Install the power cord corresponding to
the live wire, neutral wire and earth wire
respectively, and fix it by wire nail.
4. Confirm the installation position of the water heater, and drill four φ6X35mm holes on the load-bearing wall
with impact drill, with the spacing as shown in the figure below (it is also allowed to correspondingly locate
the four fixing points by placing the rear shell on the wall). And then, drive four expansion bolts into four holes
respectively, hang up the machine,and fix the machine with screws.
