S&P SILENT DESIGN Manual De Instrucciones página 15

The SILENT DESIGN is suitable for wall
or ceiling mounting and can either dis-
charge 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 wall plugs and the
screws provided.
Make a hole in the wall or ceiling of dia-
meter:
SILENT-100 DESIGN: 105 mm.
SILENT-200 DESIGN: 125 mm.
SILENT-300 DESIGN: 160 mm.
If the unit is to be installed with individual
ducting, use a standard duct of diameter:
SILENT-100 DESIGN: 100 mm.
SILENT-200 DESIGN: 125 mm.
SILENT-300 DESIGN: 150 or 160 mm.
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. In-
troduce 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).
ELECTRICAL CONNECTION
This appliance is considered to
be suitable for use in countries
having a warm damp equable
climate as specified in IEC
60721-2-1. It may also be used
in other countries.
The SILENT DESIGN is an extractor de-
signed 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 in-
sulation.
(Class II) and therefore they do not need
an earth connection.
The electrical installation must include
a double pole switch with a contact clea-
rance of at least 3 mm.
The electrical cable must enter the SI-
LENT DESIGN through the cable entry
(4).
Once the cable has been introduced pro-
ceed using the electrical wiring diagram
applicable to the selected model.

For these models use the following dia-
grams:

the light switch.
Fig.4: To switch the fan through an inde-
pendent switch.
SILENT-100 CZ DESIGN 12V
For this models use wiring diagram
Fig.11.
SILENT CRZ DESIGN
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 adjus-
table 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 anti-
clockwise (min. 1 minutes).
• To increase the "run on" time, turn
clockwise (max: 30 minutes).
