Assembly
For best results the extractor fan should be
fitted as high on the wall as possible, or on
the ceiling. It must not be installed in a
shower cabin, or be accessible to a person
using either the shower or the bath.
Precaution must be taken to avoid backflow
of gasses from the open flue of gas or other
open-fire appliances when mounted in the
outside window or walls.
1. Remove the two small screw caps on the
front, remove the screws and the front
cover.
2. Hold the body of the fan against the wall
(or ceiling) and mark the screw holes and
the cable entry.
3. Make sure the fan is square on the wall
(or ceiling) and fasten it.
4. Make the electrical connections according
to the instructions below.
5. Put the front cover back on.
Electrical Connection
Switch off mains supply before making any
electrical connections.
The extractor fan must be installed by
authorised personnel only. The wiring should
be fixed and the fan must be preceded by an
all-pole breaker with a contact gap of at least
3mm. The fans are double insulated and do
not require an earth.
The fan can be connected to the light switch,
so that it will start when the light is switched
on, or to a seperate switch.
Trim the cable (see drawing below), remove
the internal cover plate and make the
connections according to the wiring diagram.

Timer adjustment
(BF100T, BF100TH)
The time delay can be set from one minute
to 20 minutes.
Setting the timer
1. Switch off mains supply.
2. Remove front cover and inner cover plate.
3. Insert a small screwdriver into the slot and
turn clockwise to reduce the delay time
and anti-clockwise to increase it.
Humidity adjustment
(BF100TH)
The fan will stop when the time delay is
switched off at the pre-set time. If the
humidity is higher than the pre-set level, the
fan will start again and run until the pre-set
humidity level is reached.

The humidity activation level is set by
rotating the adjuster on the right. Turning it
anti-clockwise raises the level at which the
fan turns on. Turning it clock-wise lowers the
level at which the fan turns on.
