the centre of the hole.
• As far away as possible from and opposite to the main source of
air replacement to ensure airflow across the room (e.g. opposite the

• Near the source of steam or odours.
• Not where ambient temperatures are likely to exceed 50ƒC.
• If installing in a room containing a fuel burning device which
has a non-balanced flue, it is the installers responsibility to
ensure that there is enough replacement air to prevent fumes
being drawn down the flue when the fan is operating up to

4. Installing the switches and cables
1. Check there are no buried pipes or cables e.g. electricity,
gas, water behind the switch location (In the wall or above
the ceiling).
2. Lay in the cable from the isolating switch to the fan location.
3. Lay in the cable from the isolating switch to the point of
connection to the mains supply.
WARNING: DO NOT MAKE ANY CONNECTIONS TO
THE ELECTRICAL SUPPLY AT THIS STAGE.
4. Install the isolating switch.
5. Make all connections within the isolating switch.
6. Note: Switches must be so situated that they cannot be
touched by persons making use of the bath or shower.
For Australia only These models are permanently connected to the
supply and operation is controlled by a remote switch. They should
be directly wired to the supply through an approved 10A wall
mounted surface switch with at least 3mm clearance between
contacts.
5. Preparing the hole
If working above ground floor level, appropriate safety
precautions must be observed.
WARNING: EYE PROTECTION MUST BE WORN
DURING ALL DRILLING OPERATIONS.
If installing in a window, get a ready cut pane to the dimensions
given in Fig 1.
If installing in a wall:
1. Check there are no buried pipes or cables behind the wall, or
obstructions on the outside e.g. electricity, gas, or water.
2. Make sure that the centre of the hole is located at least 250mm
from the edge of the wall or ceiling.
3. Mark on the wall the centre of the hole and drill right through.
4. Draw a circle on this centre to suit the wall duct.
5. Cut the hole. Do not cut right through the wall.
(The recommended method is to drill a series of holes, close
together, around the edge of the cutting line and remove the brick
between the holes with a chisel).
6. Go outside and cut a hole in the outer wall, repeating the process
described above.
7. Fit the ducting.
8. Make good the hole. Allow the mortar to set before continuing
the Fan installation.
6. Separating the fan from the inner clamp plate
1. Remove the inner grille and back draught shutter assembly by
first removing the screw from the underside of the grille then
unclipping the bottom of the grille, the top of the grille can then
be released by unclipping the top corner. The shutter can then be
unclipped. NOTE: The top of the grille can only be released
when the screw is removed and the bottom of the grille has been
released (Fig. 2)
2. Unscrew the 4 cross-headed screws and lift off the fan (Fig. 3)
