nance. When the appliance is installed above the ceiling, the ceiling shall be
provided with a movable plate and a maintenance window for removing and
installing the appliance.
Safety drainage measures such as floor drains must be in place to prevent
leakage of appliances from causing damage to other facilities.
It must be installed indoors and where the temperature of the link is above 0℃,
so as not to cause ice to break the water pipe of the tank.
There should be no inflammable or explosive objects around the installation
appliance.
Do not reverse connection of inlet and outlet water pipes. Sealing gaskets
should be installed at the interface of inlet and outlet water pipes, and the
rotating force should be appropriate during installation.
A safety valve (a pressure relief device) shall be installed at the inlet of the
appliance through which water may flow out of the relief valve drain pipe. The
outlet of the relief valve shall be maintained in contact with the atmosphere.
The drain pipe should be securely fixed at the outlet of the relief valve.
The attachments provided by our company must be used.
Sockets providing power to appliances must be reliably grounded. Do not install
power sockets in places that may be damp or wet.
The installation must be performed by professional installation personnel.

Notice
The rated pressure of safety valve is 0.8MPa. When the pressure of the pipeline system
exceeds its rated pressure, the safety valve will automatically drain and relieve pressure,
and water flow out of the outlet is a normal phenomenon.
The drain pipe connected to the pressure relief device (safety valve) must be installed in a
continuous downward direction in a frost-free environment. (Lead the other end continuously
downward to a safe drain (such as into a floor drain) to prevent hot water from flowing out).
The blue is the water inlet, and the red is the water outlet.
If the hot water pipe is too long, it should be insulated to reduce heat loss.
When setting a power socket, determine the installation position according to the actual
length of the cable.
Test Run
① After all installation is completed, open all valves in the pipeline, then open the hot
water tap, fill the appliance with water and close the hot water tap. Check whether the
pipes are leaking. If so, reconnect the pipes.
② Unscrew the stop screw at the handle of the safety valve, pull the handle of the
safety valve, and check whether the water discharge of the safety valve is smooth
(continuous water outlet means normal).
③ After confirming normal operation, switch on the power and run the appliance acco-
rding to the operation method section. Power off and disconnect when all is well.

(1) “ ” key: Repeatedly operate this key and the system will enter power-on-wait.
(2) “ ” key: repeatedly operate this key to enter and exit the “Smart” mode in the
power-on state.
(3) “ ” key and “ ” key: in the power-on state, touch this key to adjust the set
temperature.One time increases or decreases 5 (ie 30-35-40-45...80-30), long
press is invalid. “ ” for Decrease, “ ” means increase.
(4) After the power is turned on, the actual temperature of the display (constantly
bright)/set water temperature (flashing), when setting the appointment time
(flashing display). A fault code is displayed when a fault occurs.
(5) “Smart ” light: In the “Smart ” working mode, it flashes during the statistical data
period, and is always on after the statistical data is completed.
(6) “Heating” light: the light is on in normal heating state, flashes at 1Hz in antifreeze
heating in shutdown state, and goes out in non-heating state.
2. Function description:
a. Immediate heating: in the power-on state, the water heater directly heats, when
the water heater reaches the set temperature, it stops heating and enters the
heat preservation state. After that, if the water temperature drops below the set
temperature by 8 degrees, it will be reheated, and so on. The heating light is on
when heating.
b. “Smart ”mode: In this working mode, the system analyzes, processes and
memorizes the user's water usage habits for a week, and then the system will
heat in advance according to the memorized water usage time.
c. Antifreeze: After the system is powered on (regardless of whether it is turned on
or not), as long as T≤5℃, the electric heating tube will automatically start to enter
the heating state, and when T=10℃, it will automatically exit the antifreeze
heating state.
d. Power-off memory: When the system is powered off, all parameters and working
modes are saved. After the power is restored, the parameters before power-off
are still entered into the real-time working mode.
e. Fault code display: When the system self-check fails, the two-digit digital tube
flashes to display the corresponding fault code. Among them: the dry burning
fault is E2, the sensor fault is E3, and the over-temperature fault is E4.
