FAQs

Does this kit include the ducting?

Yes, the kit is compatible with 100 mm flexible ducting, which is typically included to provide a complete installation solution.

Can I install this in a room without a loft?

This system is specifically designed as an inline kit for loft or ceiling void installations. It is not suitable for mounting on a flat ceiling without a void above it.

How do I adjust the run-on timer?

There is a small adjustment dial located on the fan unit itself. You can rotate this to increase or decrease the time the fan remains active after the power is switched off.

Is the ceiling diffuser easy to clean?

Yes, the circular diffuser is designed to be easily accessible and can be wiped clean with a damp cloth to maintain performance.

Can this be installed in a shower cubicle?

The diffuser can be placed in the ceiling above a shower, provided the electrical components (fan motor) remain protected in the loft space and all wiring is compliant with bathroom safety zones.

Troubleshooting

Fan does not turn on

Check the fuse and electrical connections at the terminal block; ensure the timer is correctly wired to both permanent and switched live feeds.

Excessive noise or vibration

Check that the fan unit is securely mounted to the joists and that the flexible ducting is not touching rigid structures that could conduct vibration.

Fan runs for too short/long a duration

Locate the adjustment screw on the fan unit housing and turn it to calibrate the run-on timer to your preferred duration.

Pros and Cons

Pros

  • Significantly quieter than standard ceiling-mounted extractor fans
  • Effective moisture removal through continuous airflow
  • Includes essential components for a complete installation
  • Adjustable run-on timer for custom moisture clearance

Cons

  • Requires loft or ceiling void access for installation
  • More complex installation process compared to wall-mounted units
  • Requires professional or experienced DIY electrical knowledge

Setup, Compatibility & Care

To install this kit, ensure you have sufficient clearance in your loft space to mount the inline fan unit securely. Connect the 100 mm flexible ducting between the ceiling diffuser and the fan unit, ensuring the bends are as gentle as possible to maintain maximum airflow efficiency.

Electrical Safety: Installation should be carried out in accordance with local building regulations. If you are not confident in handling electrical wiring, consult a qualified electrician.

Maintenance: Every 6 to 12 months, remove the ceiling diffuser cover and wipe it down with a damp cloth to remove dust accumulation. Inspect the ducting in the loft annually to ensure no kinks or blockages have occurred.
