Setup and Installation

Proper installation is crucial for the safe and efficient operation of your instant water heater. It is highly recommended that installation be performed by a certified professional.

Pre-Installation Checklist:

• Ensure the installation location has adequate water pressure (0.4-0.5 MPa).
• Verify that the electrical supply is 220V and can support a 3000W appliance. A dedicated circuit is recommended.
• Confirm the wall is suitable for mounting and can support the weight of the unit when filled with water.
• Gather necessary tools: wrench, screwdriver, drill, measuring tape, level, thread sealant tape.

Installation Steps:

1. Mounting the Unit: Securely attach the main water heater unit to the wall using the provided mounting hardware. Ensure it is level and stable.
2. Water Connection: Connect the water inlet to your cold water supply using the standard ¾" thread. Apply thread sealant tape to prevent leaks. Connect the metal spout and shower valve to the appropriate outlets on the unit.
3. Shower Head Assembly: Attach the shower hose to the shower valve and then connect the shower head to the hose. Mount the shower head holder to the wall at a convenient height.

4. Electrical Connection: Connect the appliance to a grounded 220V electrical outlet. Ensure the connection is secure and protected from water.
5. First Use Preparation: Before turning on the power, open the water faucet and allow water to flow through the unit for a few minutes to purge any air from the system. This prevents damage to the heating element.

Operating Instructions

Basic Operation:

1. Turn on Water: Open the water faucet or shower valve. Water will begin to flow.
2. Activate Heating: Once water is flowing, the unit will automatically detect the flow and begin heating the water. The LCD display will show the current water temperature.


This image provides a clear view of the main faucet unit, highlighting its integrated LCD display which shows the real-time water temperature during operation.

3. Adjust Temperature/Flow: Use the faucet handle to adjust the water flow rate and temperature. Higher flow rates may result in slightly lower temperatures, and vice-versa. The unit heats water instantaneously, so the temperature displayed is the output temperature.


This diagram illustrates how the faucet controls both hot and cold water flow, allowing users to adjust the desired temperature and flow rate for optimal comfort.

4. Turn off: Close the water faucet or shower valve. The heating element will automatically turn off.

LCD Display:

The integrated LCD display shows the real-time water temperature, typically ranging from 30°C to 60°C. This allows for precise control and monitoring of the water temperature.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your instant water heater.

• Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Aerator Cleaning: Periodically unscrew and clean the aerator at the end of the faucet spout to remove any mineral deposits or debris that may affect water flow.
• Shower Head Cleaning: If water flow from the shower head becomes uneven, clean the nozzles by gently rubbing them or by soaking the shower head in a descaling solution.
• Winterization (if applicable): If the unit is installed in an area prone to freezing temperatures, ensure all water is drained from the unit and pipes to prevent damage from freezing.
