Step 2 – Disconnect Electronics
Take out the PC electronic board and disconnect it from the plug.
Step 3 – Remove Old Solenoid Valve
Unscrew the four screws securing the old solenoid valve. Disconnect the red and black wires. Gently extract the valve and remove the diaphragm from the chamber if still present.
Tip: Have a towel or small container ready as water may leak during removal.
Step 4 – Install the New A962478NU Valve
Position the new solenoid valve and tighten the screws. Reconnect the red and black wires to the valve.
Step 5 – Reassemble and Test
Reinsert the PC board, close the control box, and restore the water supply. Test the tap to confirm successful replacement.
How the A962478NU Solenoid Valve Works
Electromagnetic Water Control Technology
The A962478NU uses solenoid technology to control water flow. A solenoid is an electromagnetic coil that creates a magnetic field when electric current passes through it.
This magnetic force moves an internal plunger, allowing water to flow through or stopping it based on input from the sensor tap.
Bistable (Latching) Design: Requires less power to stay open or closed.
One-Way Valve Function: Controls water flow in a single direction.
Normally Closed Valve: The valve remains shut when not energised.
Durable Materials
Constructed from plastic and stainless steel, this solenoid valve is built for longevity, corrosion resistance, and compatibility with a wide range of water qualities.
