Product Usage Instructions
Installation Environment Requirements
Before installing the mini water heater, ensure that the following
requirements are met:
- For kitchens, bathrooms, and toilets, the wires should be at least 2.5 square meters.
- The circuit breaker switch should be larger than C32.
- The water heater must be installed vertically and cannot be installed horizontally.
Troubleshooting
Power Light is Off
If the power light is off under normal power-on conditions, there could be two
possibilities:
- The internal overheat protection switch has tripped.
- Circuit board failure.
The Water Heater Starts Without Heating
If the water heater starts but the temperature does not rise, try the
following:
- If the water flow is too large, reduce the water flow.
- If the heating tube is damaged, replace it with a new one.
Display Shows E1
If the display shows E1, it indicates an over-temperature condition. Try the
following:
- Let cold water flow into the water heater for a while to cool it down.
- If the temperature sensor is damaged or the wiring is not connected, disconnect the power supply, open the water heater, and plug it in again. Alternatively, replace the temperature sensor before powering on.
Display Shows E2
If the display shows E2, it means the heating tube or circuit board is
damaged. Replace the heating tube or circuit board.
FAQ
No Display on Screen After Turning on the Power
Possible reasons for this malfunction include power supply problems, a damaged
circuit board, or temperature excursion protection. Check the power supply and
if the issue persists, contact professional maintenance personnel for repair.
Cold Water Only at Outlet
If you are getting cold water only at the outlet, it could be due to water
supply problems or low water pressure. Ensure that there is a normal water
supply and sufficient water pressure. If the issue persists, contact
professional maintenance personnel for repair.
No Water at the Outlet
If there is no water coming out of the outlet, check the following:
- Wait for a normal water supply.
- Ensure there is sufficient water pressure.
- Open the water inlet valve.
- Clean the water turbine if it is blocked.
Installation And Use Of Mini Water Heaters
Installation environment requirements: For kitchens, bathrooms, and toilets, the wires are required to be 2.5 square meters; the circuit breaker switch is larger than C32; the water heater is required to be installed vertically and cannot be installed horizontally;
Trouble Shooting
-
If the power light is off, check whether the power supply is normally energized. If the power light is off under normal power-on conditions, there are two possibilities.
-
The internal overheat protection switch has tripped.
-
Circuit board failure.
-
The power light is on but not heating.
-
The water flow does not pass through the water heater.
-
The water pressure is too low to cause the water heater to start. If the water pressure is sufficient, the water flow normally flows through the water heater, but if the water heater does not heat up, then check the turbine inlet of the water heater, there may be something dirty stuck to the turbine, causing the water heater not to start. Please take out the turbine of the water heater, clean it, and put it back.
-
The water heater starts without heating, the power lamp shows numbers, and the temperature does not rise.
-
If the water flow is too large, you can reduce the water flow.
-
The heating tube is damaged, just replace the heating tube.
-
Installation condition:
The length of the water pipe connected to the water outlet of the water heater is recommended not to exceed 3 meters. If it exceeds the length, the water pressure difference may be caused by the length of the water pipe, and the water pressure is not enough for the water heater to start. If the water tower is used in rural areas, the height of the water tower is required to be higher than 10 meters to make the water pressure reach the starting value. -
The display shows E1.
-
It means over-temperature. Let cold water flow into the water heater for a while.
-
The temperature sensor is damaged or the temperature sensor wiring is not plugged in or disconnected. Firstly disconnect the power supply, then open the water heater and plug it in again, or replace the temperature sensor before power on.
-
The display shows E2.
The heating tube or circuit board is damaged. Replace the heating tube or circuit board.
