DESCRIPTION
The VA100 from Vent-Axia is a 100mm extract fan for domestic bathrooms and WC’s
available as window, wall or panel mounted models. Model options with shutter, timer
and auto humidity control.
ACCESSORIES (not supplied)
A range of 100mm wall and window kits are available for
installing into most walls/windows using telescopic
liners/spacers supplied.
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.
4. Repeat for the external grille sub-frame. Fix exterior grille into position with the
louvres positioned downwards.
AFTER INSTALLATION ENSURE IMPELLER ROTATES FREELY
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST
BE ISOLATED FROM THE POWER SUPPLY DURING THE
INSTALLATION / OR MAINTENANCE.
B. WIRING.
IMPORTANT: There are two methods of cable entry to the fan. If the side cable entry
option is used, ensure the supplied grommet is used and maintains a good
seal to prevent water ingress.
The VA100 is suitable for connection to 220-240V/1/50Hz supply. It is class
II double insulated and MUST NOT be earthed.
1. Select and follow the appropriate wiring diagram. (Fig. 2, 3 or 4)
2. Check all connections have been made correctly and ensure all terminal
connections and cable clamps are securely fastened.
3. Ensure the impeller rotates and is free from obstructions.
C. SETUP
TIMER ADJUSTMENT (VA100LT, VA100XT & VA100XHT)
BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER
SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.
1. Remove the fan grille. The controller is factory set at 15 minutes approx.
The overrun time period can be adjusted from 3-25 minutes by altering the
adjuster on the control PCB.
2. To REDUCE the operating time, use a small screwdriver to turn the
adjuster ANTI-CLOCKWISE.
3. To INCREASE the operating time, use a small screwdriver to turn the
adjuster CLOCKWISE.
4. Replace the fan grille.

HUMIDITY SET-POINT ADJUSTMENT
BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY.
HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE OR DURING
INSTALLATION.
1. Remove the fan grille. The controller is factory set to switch on at about
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.
3. To RAISE the set-point use a small screwdriver to turn the adjuster
CLOCKWISE. This makes the controller LESS sensitive.
4. Replace the fan grille.
IMPORTANT: Upon installation it is possible that the humidity controller will make the
fan run continuously until it has acclimatised to the environment. As part of the
installation process it is important to set/adjust the humidity sensitivity to the desired
position. The controller is already factory set to switch on at about 70% R.H.
SHUTTER OPERATION
The shutter mechanism in all VA100‘X’ model fans will open approximately one minute
after the fan is turned on. The shutter will close about a minute after the fan is switched
off.
PULLCORD OPERATION (VA100LH, VA100XH)
The PULLCORD will activate the fan when switched. When the PULLCORD is
switched into the off position, After which the fan will return to the Auto sensing mode.
The Neon will only activate if the PULLCORD is in the ON position.
NEON OPERATION
The Neon will activate whenever the LS or PULLCORD is activated. The NEON will
switch off if the fan is running in Timer overrun or Humidity mode (if applicable).
D. SERVICING AND MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to
ensure there is no build up of dirt or other deposits.
2. Wipe the inlets and front face with a damp cloth until clean.
The fan has sealed for life bearings, which do not require lubrication.
