S&P EB-100 Bedienungsanleitung Seite 12

re that there are no obstructions to the
airflow, that the shutter mounted at the
fan discharge opens easily and that the
impeller turns freely.
Fix the fan support to the wall with the 4
plugs and screws supplied in the packa-
ging. Loosen the screws of cover (4) to
gain access to the connection terminals.
Connect the electrical wiring as follows.
Electrical connection
The EB is an extractor designed for a
single phase supply, with voltage and
frequency as indicated on the rating
plate of the unit. The EB models are
made Class II (double electrical insula-
tion) and the EB 12V are made Class III
and therefore they do not need an earth
connection.
IMPORTANT: The safety isolating
transformers CT-45/12 used with EB
12V must be earth connected.
The electrical installation must include a
double pole switch with a contact clea-
rance of at least 3 mm.
The electrical cable must be introduced
to the EB through the slot (6) if the wire
is within the wall or through the cable
entry (5 if the installation is made with a
surface mounted cable.
Once the cable has been introduced,
proceed to the appropriate electrical wi-
ring depending on the EB model.
EB models S
For these models use the following dia-
grams:
Fig. 3: To switch the fan through an in-
dependent switch.
Fig. 4: Switching the extractor through
the light switch.
EB models S (12V~50Hz)
For these models use the CT-45/12 sa-
fety isolating transformer:
Fig. 9: To switch the transformer and
the extractor through an inde-
pendent switch.
Fig. 10: Switching the transformer and
the extractor through the light
switch.
EB models T
Models fitted with an adjustable timer,
variable between 1 and 30 minutes. The
timer enables the extractor to continue
running during the time delay, after the
supply has been switched off.
The diagram on Fig. 5 shows how to
connect a unit fitted with timer using an
independent switch.
The diagram on Fig. 6 shows how to
connect a unit fitted with timer using the
light switch.
To adjust the timer, turn the potentio-
meter in the lower part of the fan with a
small screwdriver:
- To increase the time delay turn it Cloc-
kwise (CW).
- To decrease the time delay turn it
Counter Clockwise (CCW).
EB models T (12V~50Hz)
For these models use the CT-45/12 sa-
fety isolating transformer:
Fig. 11: To switch the transformer and
the extractor through an inde-
pendent switch.
Fig. 12: Switching the transformer and
the extractor through the light
switch.
EB models HT
This model is provided with an elec-
tronic hygrostat which can be adjusted
from 60 to 90 % RH (% relative humi-
dity).
The two functions, timer and humidity
control, are independent The adjust-
ments are carried out with the potentio-
meter in the lower part of the appliance
(fig.7).
