SILENT-100 Axial Extractor Fans
IMPORTANT
The SILENT-100
extractor fan range is
manufactured to the high standards of
production and quality as laid down by the
international Quality Standard ISO 9001. All
components have been checked and every
one of the final products will have been
individually tested at the end of the
manufacturing process.
On reciept of the product we recommend that
you to check the following :
1- That it is the correct size.
2- That it is the correct model.
3- That the details on the rating label are
those you require: voltage, frequency ...
The installation must be carried out in
accordance with the electrical standards in
force in your country.
: Before installing and wiring
the unit, ensure that the main supply is
disconnected.
1: Protection grille
3: Outlet with backdraught shutter
2: Connection terminals
4: Cable entry
The SILENT-100 is suitable for wall or ceiling
mounting and can either discharge directly to
the outside or via an individual ducting
system (see Fig. 2).
The unit can be mounted on the wall or
ceiling using the 4 rubber blocks and the
screws provided.
Make a hole in the wall or ceiling of 105 mm
dia.
If the unit is to be installed with individual
ducting, use a standard 100 mm dia. duct.
Ensure that there are no obstructions to the
airflow and that the impeller turns freely.
Fix the extractor to the wall in such a way that
it is not distorted in order to avoid noise
generation or problems with the rotation of
the impeller. Make sure that the backdraught
shutter opens freely and has not being
damaged in transit. Introduce the mains
cable through the cable entry (4) and fix it to
the wall.
Connect the electrical wiring as set out below
and then mount the protection grille (1).
The SILENT-100 is an extractor designed for
a single phase supply, with voltage and
frequency as indicated on the rating plate of
the unit. The units are manufactured with
double electrical insulation
(Class II) and therefore they do not need an
earth connection.
The electrical installation must include a
double pole switch with a contact clearance
of at least 3 mm.
The electrical cable must enter the SILENT-
100 through the cable entry (4).
Once the cable has been introduced proceed
using the electrical wiring diagram applicable
to the selected model.
For these models use the following
diagrams:
Fig.3: Switching the extractor through the
light switch.
Fig.4: To switch the fan through an
independent switch.
This model is provided with an adjustable
over-run timer. The timer allows the fan to
continue to operate for the selected period
after the switch has been turned off (fig.6).
Model provided with a 4 positions adjustable
electronic timer:Fig.5 shows how to connect
the fan with timer utilising the same switch as
for the lighting circuit.
To set the timer, turn the potentiometer on the
printed circuit board as (fig. 7).
- To reduce the "run on" time, turn
anticlockwise (min. 1 minutes)
- To increase the "run on" time , turn
clockwise (max: 30 minutes).
