These models are fitted with automatic electronic humidity sensing. The humidity sensor needs free air circulation so do not site close to cupboards, etc. Do not site above a radiator or other heat source.

PANEL/CEILING MOUNTING

IMPORTANT : The fan should be installed into a closed duct system or protected by an exterior air grille.

1. Cut a 105mm diameter hole in the fixing surface.
2. Remove the grille by loosening the screw at the bottom of the grille.
3. Mark the screw centers through the holes in the fan back plate. Drill, plug and screw into position.
4. Replace the grille and tighten the screw.

WINDOW MOUNTING (Window kit not supplied – see Accessories above)

1. Cut a 105mm diameter hole in the glass.
2. Fit spacers as required behind the fan backplate, engaging the locating pips in the corner holes.
3. Place the fan spigot through the hole in the glass from the inside, with a gasket on each side of the glass.
4. From the outside, place on the remaining spacer, with the locating pips facing outwards. For double-glazing and materials up to 40mm thick, one or more spacers may be discarded.
5. Draw the assembly together with the threaded fixing ring. Do not over-tighten.
6. Fix the exterior grille in position, using the screws provided, with the louvers pointing downwards.

WALL MOUNTING (Wall kit not supplied – see Accessories above)

1. Cut a 115mm diameter hole through the wall and insert the wall sleeve with the large diameter sleeve on the room side. Slope the sleeve slightly downwards away from the fan. Cement both ends into position flush with the wall faces.
2. Remove the grille by loosening the screw at the bottom of the grille.
3. Mark the screw centers on the wall through the holes of the fan back plate. Drill plug and screw into position.
