Manrose Axial Tiled Extractor Fan - 100mm Timer Model (Black)

This fan requires three core wires: permanent live, switched live, and neutral (excluding earth). The switched live controls the fan via the light switch, and the permanent live powers the timer overrun.

The timer overrun duration is typically pre-set during manufacturing and may not be user-adjustable without specific internal modifications, which should only be performed by a qualified professional.

While specific lengths vary, axial fans are best suited for short duct runs (typically under 3 meters) with minimal bends. For longer or more complex runs, a centrifugal fan might be more appropriate.

It is recommended to clean the fan grille and blades at least every 3-6 months, or more frequently in very humid or dusty environments, to maintain optimal performance.

The fan has a 100mm (4-inch) diameter spigot for connecting to ducting.

Yes, it is designed for bathroom and toilet locations and will help extract steam. Ensure it is installed according to safety regulations for bathroom zones.

The fan measures 158mm high x 158mm wide. The depth extending beyond the installed surface is 34mm.

Check that the switched live connection is correctly wired and receiving power when the light is on. Ensure the permanent live and neutral wires are also properly connected.

Verify the permanent live and neutral connections are secure. The timer function relies on the permanent live feed to continue operation. Check the wiring diagram for correct connection of all three core wires.

Ensure the fan is securely mounted. Check the ducting for any obstructions or kinks that might be causing air resistance. Clean the fan blades of any accumulated dust.

Inspect the ducting for blockages. Clean the fan grille and blades. Ensure the duct run is not excessively long or has too many bends, which can reduce axial fan performance.
