F1B Urinal Sensor Installation Manual

Connect the Battery Pack

1. Remove the four screws securing the back panel using a star screwdriver, then remove the panel.
2. Locate the sealed black battery pack and its red connector.
3. Locate the red connector coming from the sensor.
4. Push the two connectors together to connect the battery pack.
5. Check that the sensor responds: a red LED blinks when the unit senses a user.
6. Refit the back panel and its screws.

Fix the Unit to the Wall

Use the two mounting holes on the sides of the unit to secure it to the wall.

Important: Tighten the mounting screws by hand. Do not hammer the screws or the unit, as this can damage the plastic housing.

Connect the Inlet and Outlet Hoses

Use two plastic hoses for the inlet and outlet connections.

Important: Do not use metal hoses. They can damage the unit's plastic threaded fittings.

1. Before connecting the inlet hose, flush approximately one bucket of water out of the supply pipeline to clear dust and sediment.
2. Connect the inlet hose to the sensor unit's inlet.
3. Connect the outlet hose to the sensor unit's outlet.
4. Connect the other end of the outlet hose to the urinal bowl's spreader.

Keep dust and sediment out of the inlet. Particles entering the unit can cause it to malfunction.

Automatic Flushing

• Pre-flush: When a user stands in front of the sensor, it flushes for approximately one second.
• Post-flush: When the user leaves, it flushes for four to six seconds, depending on the usage time.
