Frequently Asked Questions (FAQs)

Q: Can this fan be installed directly above a shower?

Q: Does the fan include a backdraught shutter?
A: While this specific kit may not include a built-in backdraught shutter, optional inline shutters can be added to prevent cold air ingress.

Q: How do I set the timer duration?
A: The timer is adjustable via a small dial on the fan unit. A qualified electrician can set this during installation to between 1 and 30 minutes.

Q: Can this unit be installed horizontally or vertically?
A: Yes, it is flexible in mounting position and can be installed horizontally or vertically in most loft or ceiling spaces.

Q: Is the ducting provided insulated?
