2. Important Safety Instructions
Please read all safety instructions carefully before installation and use. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Electrical Safety: Ensure the product is connected to a 220V/UK electrical outlet with appropriate amperage (≥20A) and a 16A air switch.
- Water Flow First: Always activate water flow through the faucet before turning on the power supply. This is critical during initial use and after any period of disuse to prevent dry heating, which can damage the unit.
- Temperature Protection: The faucet features an integrated double protection system that automatically cuts power during circuit anomalies or dry heating. It also includes overheating protection.
- Leakage Protection: Equipped with leakage protection and water-electricity separation technology for enhanced safety.
- Winterization: Disconnect the power supply and drain the water from the faucet when ambient temperatures are expected to drop below 0 °C (32 °F) to prevent damage from freezing.
- Water Pressure: Ensure your home's water pressure is within the required range of 0.04-0.5 MPa (0.4-5 Bar). If water is supplied from a roof tank or well, an additional water pressure increasing pump may be necessary.
- Waterproof Rating: The unit has an IPX4 waterproof rating, meaning it is protected against splashing water from any direction. However, it should not be submerged.
- Installation: Installation should be performed by a qualified professional if you are unsure. Ensure all connections are secure and leak-free.

5. Installation Guide
The Briwellna Instant Hot Water Faucet is designed for easy installation and can be mounted either above or under the sink. While a multilingual user manual is included, professional installation is recommended if you are not familiar with plumbing and electrical work.
5.1 Pre-Installation Checks
- Verify that your electrical system meets the voltage (220V), amperage (≥20A), and air switch (16A) requirements.
- Confirm your water pressure is within 0.04-0.5 MPa (0.4-5 Bar).
- Ensure the water connector size is 1/2 inch. An adapter may be needed for 3/8 inch connections.
- Check the diameter of the plug (36mm) and the water tube size (inner diameter 19mm, outside diameter 22mm) to ensure compatibility with your sink's punch hole.
Figure 8: Installation options (above or under sink) and dimension checks for water tube and plug.
5.2 Installation Steps
- Prepare the Installation Area: Turn off the main water supply and electrical power to the installation area. Clear the space under and around the sink.
- Mount the Faucet: Insert the faucet into the designated hole on your sink or countertop. Secure it from underneath using the provided mounting hardware and gaskets.
- Connect Water Lines: Connect the flexible water hose to the faucet's inlet and then to your cold water supply line. Ensure all connections are tight to prevent leaks.
- Connect Electrical Power: Route the power cord to a suitable 220V electrical outlet. If the plug is too large for the cabinet opening, it can be unscrewed to pass the wires through, then reassembled.
Figure 9: Illustration of how the plug can be unscrewed to allow wires to pass under the counter.
- Test for Leaks: Slowly turn on the main water supply and check for any leaks around the faucet and connections.
- Initial Water Flow: Before plugging in the faucet, open the faucet handle to allow water to flow through the unit for a few seconds. This purges air and ensures the heating element is submerged.
- Connect to Power: Once water is flowing steadily, plug the faucet into the electrical outlet.
6. Operation
The Briwellna Instant Hot Water Faucet offers simple operation with a single lever for both water flow and temperature control.
6.1 Hot and Cold Water Control
- The faucet provides both hot and cold water.
- Move the lever to control the water flow and temperature.
- To increase hot water temperature, decrease the water flow by moving the lever towards the 'Hot' indicator. The smaller the water flow, the higher the temperature, generally ranging from 25℃ to 50℃.
- The digital display on the faucet will show the current water temperature.

6.2 Temperature Variation
The actual hot water output temperature is influenced by the inlet water temperature and the flow rate. Refer to the following maps for estimated temperatures based on geographical location and season:
Figure 12: Estimated hot water temperatures during summer across Europe.
Figure 13: Estimated hot water temperatures during winter across Europe. Note: If inlet water temperature is below 5°C, outlet temperature may not reach 40°C with a flow of 1.5L/min.
7. Maintenance and Care
Proper maintenance ensures the longevity and efficient operation of your Briwellna Instant Hot Water Faucet.
- Cleaning: The faucet features an eco-friendly ABS plastic housing that is easy to clean. Use a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads that could damage the finish.
- Winterization: As mentioned in the safety instructions, if the faucet is in an unheated area where temperatures may drop below 0 °C, disconnect the power and drain the water from the unit to prevent freezing and damage.
- Regular Checks: Periodically inspect the water connections for any signs of leaks or corrosion.

8. Troubleshooting
If you encounter issues with your Briwellna Instant Hot Water Faucet, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water or insufficient heating | No power; water flow too low or too high; inlet water temperature too low; dry heating protection activated. | Check power connection and circuit breaker. Ensure water flow is within 600-850ml/min. Adjust flow rate to increase temperature. If inlet water is very cold (below 5°C), maximum temperature may be limited. Ensure water is flowing before power is applied. |
| Digital display not working | No power; internal fault. | Check power connection. If power is on and display is still off, contact customer support. |
| Water leakage | Loose connections; damaged gaskets. | Tighten all water connections. Inspect and replace any damaged gaskets. Turn off water supply before attempting repairs. |
| Low water pressure | Insufficient main water pressure; clogged aerator. | Check household water pressure. Clean or replace the faucet aerator. If water is from a non-city source, consider a pressure pump. |
| Flickering digital display or inconsistent heating | Unstable power supply; internal sensor issue. | Ensure stable power supply. If the issue persists, contact customer support. |
