Installation Manual
Opening the Packing Materials
Attention: Do not remove any of the permanent instructions and labels, no matter inside or outside.
Dismantle the exterior packing and place installation components aside.
•Inspect all parts prior to installation and start-up. Make sure there is no visible damage.
•Completely read all instructions before assembling and install.
•After installation, dispose of packaging material in the proper manner.
Location Requirements
Select a location near the water piping system. Hot water pipe shall be kept as short as possible to prevent
excessive heat loss.
Note:
1. For the best installation, make sure there is at least 1.8 meters distance between the hook of water
heater and the floor. (Refer to installation drawing for more details，Please see page **)
2. Power switch must be away from the water outlet, or make sure there is at least 1.2 meters distance
between them. It can be dangerous when water splashes to the power.

3. The water heater must be installed indoors, it should be located in an area not subject to freezing
temperatures.
4. The material of water heater cover is ABS, so require there is no heat source or combusibles (Cabinet,
curtain, carton ect.) near water heater.
5. Water outlet must be connected to normal water faucet or connecting point.
Electrical Requirements
We highly recommend you to get a qualified electrician to install the water heater
instead of performing by yourself, unless you are qualified for electrical installation.
In process to the electrical connections, make sure to follow points as following:
A. A separate switch is required to be installed.
B. The use of a plug and socket is NOT recommended.
And choose the RCCB(Air-break switch) or junction box according to the table of technical parameters.
C. The water heater and electrical supply must be earthed.
D. The water heater should the independent wiring, not probably use in common a line with other electric
appliances.
E. All wiring MUST meet the local regulations. Any interrogations, please consult a qualified electrician. A
type connections is shown in Picture
F. Correct size of wire conductor corresponds to different electrical loading should be used. The following
table provides a reference for selection the best type of wire conductor.

1. The unit should be wall-mounted installed.
2. Determine the right position of installation for the unit; According to Figure 6 and Figure 5（a）to drill 3
holes on the wall.
3. Drive the expansion bolts in the hole (1),(2) & (3) fix the screws into the expansion bolts, make sure it’s
fully fasttened and the screws head away from the wall surface have 6mm~8mm distance.
4. Fixed the hook on the hole (3) with the nut: the hook's long side is adown, the short side is towards the

enters in standby mode.
2. Switch on the water heater by press “ ”. The display screen will display the setting temperaure & real
outlet water termperature.
3. The user can set the desired temperature by touch the control button “+”, “-”. Press the “+” or “—”button
each time,the temperature will increase or decrease 1℃.
4. The user can also set temperature by slide the touch aera. Slide touch slowly from left to right or from
