Pros and Cons

Pros

Flexible mounting options for walls or ceilings
Adjustable timer prevents excess moisture accumulation
Durable, long-life, double-insulated motor
Meets Building Regulation Document F requirements
Integrated backdraught shutter prevents external air inflow

Cons

Noise level of 36dB(A) may be audible in smaller bathrooms

Setup, Compatibility & Care

To install this unit, you must prepare a wall hole diameter of 117mm. The fan supports both rear and side exit spigots, allowing you to route ducting according to your specific wall or ceiling structure.

Installation Steps:

Ensure power is isolated at the mains before starting.
Cut the required 117mm hole in your chosen location.
Mount the casing flush or surface as preferred using the provided high-impact moulding points.
Connect the electrical supply to the timer terminal.
Adjust the overrun timer setting via the internal electronic module.

Care:

Periodically wipe the external gloss cover with a damp, soft cloth to prevent dust buildup. Avoid using abrasive cleaners that could scratch the finish. The internal motor is sealed and maintenance-free, though the shutter should be checked occasionally to ensure it opens and closes freely.
