DESCRIPTION
The Lo-Carbon VA100 fan is an axial extraction fan suitable for domestic
bathrooms and WC’s and is with shutter timer and humidity combinations. The fan
can be wall, panel/ceiling or window mounted using the appropriate ducting/grille
kit (see Accessories section below).
Long life ball bearing DC motor with anti-vibration mounts provides low noise
transmission into plasterboard/panels for quiet operation compared with other DC
motor based fans.
ACCESSORIES (not supplied) Please see www.vent-axia.com for more
information.
WALL FITTING KIT
A range of 100mm wall kits are available for installing into most walls using
telescopic liners supplied. White stock ref.: 254102, Brown stock ref: 254100.
WINDOW FITTING KIT
Two window kits are available, for existing 105-110mm diameter holes and a
glazing thickness of 10-25mm use stock ref. 254101A. For 110-140mm holes and
a glazing thickness of 17mm and 43mm use stock ref. 443234.
A. INSTALLATION
PANEL/CEILING MOUNTING
1. For panel/ceiling mounting the fan should be installed into a closed duct
system of at least 1.2m long (max 3m) or protected by an exterior air grille
that must comply with the standard requirements of your country to prevent
access to the fans impeller.
2. Cut a 105mm diameter hole.
3. Loosen the screw at the bottom of the grille and remove the grille. Mark the
screw centres through the holes in the fan back plate. Drill, plug and screw
into position.
4. Attach ducting as required for the installation.
5. Wire the fan as described in Section B-Wiring. Adjust any settings as
required (see Section C-Setup).
6. Replace the grille and tighten the retaining screw.
7. After installation, ensure impeller rotates freely and the shutters can open.
WALL MOUNTING (WALL KIT SUPPLIED SEPARATELY – SEE ACCESSORIES ABOVE)
1. For wall mounting cut a 117mm diameter hole through the wall and insert
the wall sleeve. Slope the sleeve slightly downwards away from the fan. Cut
to length and cement both ends into position flush with the wall faces.
2. Loosen the screw in the bottom of the grille and remove the front grille. Mark
the screw centres through the holes in the fan back plate. Drill, plug and
screw into position. Fix exterior grille into position with the louvres positioned

downwards. (Note:- The grille must comply with the standard requirements
of your country to prevent access to the fans impeller)
3. Wire the fan as described in Section B-Wiring. Adjust any settings as
required (see Section C-Setup).
4. Replace the grille and tighten the retaining screw.
5. After installation, ensure impeller rotates freely and the shutters can open.
WINDOW MOUNTING (WINDOW KIT SUPPLIED SEPARATELY – SEE ACCESSORIES ABOVE)
The following instructions are for 105-110mm holes only – using the
254101A window mounting kit. For 110-140mm holes please use
443234 window kit and refer to the supplied instructions.
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.
AFTER INSTALLATION ENSURE IMPELLER ROTATES FREELY
B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT
MUST BE ISOLATED FROM THE POWER SUPPLY DURING THE
INSTALLATION / OR MAINTENANCE.
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.
The fan must be powered at all times to allow the shutter to work correctly. If there
is a requirement to switch the fan via an external switch, this should be connected
to the LS connection and not by switching L/N supply.
1. Select and follow the appropriate wiring diagram. (Fig. 2 or 3)
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
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT
MUST BE ISOLATED FROM THE POWER SUPPLY DURING THE
INSTALLATION / OR MAINTENANCE.
SPEED SETTING (Fig. 4):
The fan has two speed settings for different installation requirements:
1) High speed – for ducted installations: Replace jumper.
2) Normal speed – for wall/window installations: Remove jumper.
TIMER ADJUSTMENT (LT/XT/LHTP/XHTP MODELS)
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 approximately
1-30 minutes by altering the adjuster on the control PCB.
2. To REDUCE the operating time, use a small screwdriver to turn the
adjuster Fig.4. ANTI-CLOCKWISE.
3. To INCREASE the operating time, use a small screwdriver to turn the
adjuster Fig.4. CLOCKWISE.
4. Replace the fan grille.
HUMIDITY SET-POINT ADJUSTMENT (LHTP/XHTP MODELS ONLY)
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 65-
95%RH by altering the adjuster on the control PCB.
2. To LOWER the set-point use a small screwdriver to turn the adjuster
Fig.4. ANTI-CLOCKWISE. This makes the controller MORE sensitive.
3. To RAISE the set-point use a small screwdriver to turn the adjuster
Fig.4. 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%RH. If the room has not had a fan correctly working for sometime, the fan may
run continuously for 2 or more weeks until the humidity drops below 70%RH.
PULLCORD OPERATION (LP/XP, LHTP/XHTP)
The PULLCORD will activate the fan when switched. For the HTP models, the fan
will return to the auto humidity sensing mode once the pullcord is switched into the
off position. The LED indicator light will only activate if the PULLCORD is in the
ON position.
LED INDICATOR LIGHT OPERATION
The Neon will activate whenever the LS or PULLCORD is activated. The LED
indicator light will switch off if the fan is running in Timer overrun or Humidity mode
(if applicable).
D. SERVICING AND MAINTENANCE.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT
MUST BE ISOLATED FROM THE POWER SUPPLY DURING
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.
