FAQs
Does this fan require a permanent live connection?
Yes, to enable the overrun timer functionality, a permanent live wire is required alongside the switched live and neutral.
Can this fan be installed in a shower cubicle?
It is generally recommended for use in bathroom zones, but always consult local electrical regulations regarding safe distances for ventilation equipment.
Is the timer adjustable?
Yes, the unit features an adjustable timer that allows you to set the overrun duration to suit your specific room size and ventilation needs.
What is the diameter of the ducting required?
This fan is designed to fit 150mm diameter ducting.
Does the unit include a backdraft shutter?
Most standard axial fans rely on external grilles for backdraft protection; ensure your external wall grille is equipped with a shutter if needed.
Troubleshooting
Fan does not run when the light is switched on
Verify that the permanent live, switched live, and neutral wires are connected to the correct terminals.
Fan stays on indefinitely
Adjust the internal timer potentiometer to reduce the overrun duration, or check for a faulty switch connection.
Unit is vibrating or noisy
Check that the mounting screws are tightened securely and that the fan is mounted on a flat, stable surface.

Setup, Compatibility & Care
Installation must be performed by a qualified electrician to ensure safety and compliance with building regulations. The unit requires a three-core and earth cable connection to utilize the timer function properly (permanent live, switched live, and neutral). For maintenance, ensure the fan is isolated from the power supply before cleaning. Periodically wipe the exterior grille with a damp cloth to prevent dust buildup, which can restrict airflow. Avoid using abrasive chemicals or high-pressure water near the electrical components.
