• Near the source of steam or odours.

• Not where ambient temperatures are likely to exceed 50°C.

• 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
maximum extract. Do not install in a room containing a solid
fuel appliance.
Refer to Building Regulations for specific requirements.

Exhaust air must not be discharged into a flue used for
exhausting fumes from appliances supplied with energy other
than electric.

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 and the on/off switch or controller if

required.

switch or controller if required.

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 205mm
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.
