WINDOW MOUNTING (Window kit not supplied – see Accessories above)
1. For new installations cut a 115mm diameter hole in the glass. (use window kit 443234)
(Note:- If using an existing 105mm diameter hole in the glass, use window kit 254101A)
2. Refer to the instructions supplied with the window kit 443234. Or if using kit 254101A
read the following instructions below.
3. Fit spacers as required behind the fan back plate, engaging the locating pips in the corner holes.
4. Place the fan spigot through the hole in the glass from the inside, with a gasket on each side of the
glass.
5. 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.
6. Draw the assembly together with the threaded fixing ring. Do not over-tighten.
7. 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
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 controller is only suitable for connection to a 220-240V 50Hz AC single phase
mains electrical supply. It is double insulated (CLASS II) and therefore must not be
earthed. It provides a 12V 50Hz AC Safety Extra Low Voltage for the VA100 SELV 12
range of fans. Note that only one fan must be connected to the controller.
1.5mm² wire is recommended for cable runs up to 8m.
1. Select and follow the appropriate wiring diagram. (Fig. 2, 3,4 or 5)
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.
TIMER ADJUSTMENT (VA100SVXT12/ VA100SVXHT12)
BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER SHOULD ONLY BE
ADJUSTED BEFORE OR DURING INSTALLATION.
External Timer: VA100SVXT12
Unscrew the fixing screws holding the controller to the mounting box. The fan overrun period can be adjusted
up or down using the adjuster located on the internal PCB.
