DESCRIPTION
The Silhouette 100mm & 125mm axial extract fans are suitable for domestic bathrooms and W.C’s. The
Silhouette 125mm & 150mm axial extract fans are suitable for domestic kitchens and utility rooms. They
are available as wall or panel/ceiling mounted models with shutter, timer, humidity and PIR combinations
(100mm model only).
ACCESSORIES (not supplied)
WALL FITTING KIT
A range of 100mm, 125mm and 150mm wall kits are
available for installing into most walls using telescopic
liners supplied.
A. INSTALLATION
IMPORTANT: The fan should only be used in conjunction with fixed wiring.
1. For panel/ceiling mounting the fan should be installed into a closed duct 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 for 100mm fans, a 130mm hole for 125mm fans or a 155mm
diameter hole for 150mm fans.
3. Loosen the screw at 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.
4. After installation, ensure impeller rotates freely and the shutters can open.
5. Replace the grille and tighten the retaining screw.
WALL MOUNTING
1. For wall mounting either cut a 115mm diameter hole for 100mm fans, a 140mm hole for 125mm
fans or a 170mm diameter hole for 150mm fans, 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. The wall kit used in this
installation should provide a minimum ducting length of 100mm from the fans back plate to the
inside of the external grille).
3. After installation, ensure impeller rotates freely and the shutters can open.
4. Replace the grille and tighten the retaining screw.

B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE
.
IMPORTANT
• The fan should only be used in conjunction with fixed wiring.
• The cross - sectional area of supply cord used should be ranged from 1 -1.5mm2.
• Cable entry can only be made from the rear of the fan.
• The extraction fan is suitable for connection to 220-240V 50Hz supply.
• The fan is a class ll double insulated product 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
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
NOTE
On all 150mm fans the shutter may take up to one minute to activate on start-up, and the same amount
of time to close when the fan is switched off.
SILHOUETTE 100B/125B/150X
Single speed fan. Controlled by remote switch (e.g. light switch or auto sensor) Fig.2.
SILHOUETTE 100T/125T/150XT
Single speed with overrun timer. The fan can be wired to a lighting circuit switch. Fig.4. or wired for a
basic on/off operation wire as Fig 3.
When switched ‘ON’, the fan will operate at full speed and will continue to run for a pre-set time after the
switch is turned ‘OFF’.
TIMER ADJUSTMENT
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 5-25 minutes by altering the adjuster on the control PCB.
2. To REDUCE the operating time, use a small screwdriver to turn the adjuster Fig.5. ANTI-
CLOCKWISE.
3. To INCREASE the operating time, use a small screwdriver to turn the adjuster Fig.5.
CLOCKWISE.
4. Replace the fan grille.
SILHOUETTE 100HT/125HT/150XHT
The fan contains an integral humidity controller. In automatic mode the controller switches the fan on at
full speed when the room Relative Humidity (RH) reaches the set-point. The fan will continue to run until
the room RH falls below the set-point.
These fans also include a built in timer function. The timer can be activated by removing the Jumper
JP1, this will give the fan a fixed over run time of approx. 15 mins.

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 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.6. ANTI-
CLOCKWISE. This makes the controller MORE sensitive.
3. To RAISE the set-point use a small screwdriver to turn the adjuster Fig.6. CLOCKWISE.
This makes the controller LESS sensitive.
4. Replace the fan grille.
NOTE! DO NOT TOUCH HUMIDITY SENSOR.
SILHOUETTE 100TM
Single speed with PIR (passive infra-red) detector and overrun timer. The fan starts automatically when
a movement is detected and will continue to operate for the set overrun time period.
(See ‘Timer Adjustment’ section above) Fig. 2 and 5.
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.
