Installing a ventilating fan in your bath will help eliminate fogged-up windows, steamy mirrors and stale odors. But more importantly, it will help prevent moisture-related problems, such as the growth of mold and mildew.

A bathroom without a ventilation fan is like a fireplace without a chimney: If you fail to pull the moisture generated in the bathroom out of there, it will migrate into the walls and grow mold and mildew, or blister paint and peel wallpaper. One reason many households still don't have bath fans is that they can be intimidating to install.

The following instruction is based on the 3 in 1 bathroom fan we are selling.

Mounting

    The unit may be mounted either between joists using the inbuilt clip fasteners or against a joist using a screw through the flange plate. Use the template Card within the package and place in the required location and mark out the hole cutting size. Hole size is 295mmx295mm.







  2. Cut the hole for the intake port
    For this step, be sure to wear protective goggles and a dust mask or respirator.
    Before commencing cutting ensure that the area behind the intended location is clear of all cables, pipes and joists. Once clear, Using a jigsaw (a reciprocating saw or drywall saw will also work), cut through the ceiling on the layout lines.
    When you're almost finished making the rectangular cutout, support the waste piece with one hand to keep it from falling and possibly taking some of the surrounding drywall or plaster ceiling with it.
