A. INSTALLATION
WHERE TO FIT
A short circuit of the airflow should always be avoided by positioning the fan as far
away as possible from and opposite to the main source of air replacement. Fig. 1.
VA100LH, VA100XH and VA100XHT. 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 centres through the holes in the fan back plate. Drill, plug and
screw into position.
4. Replace 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 back plate, 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 louvres
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 centres on the wall through the holes of the fan back plate. Drill
plug and screw into position.

70% RH. The humidity set point can be adjusted from 40-95%RH by
altering the adjuster on the control PCB.
2. To LOWER the set-point use a small screwdriver to turn the adjuster ANTI-
CLOCKWISE. This makes the controller MORE sensitive.
