the shutter mounted at the fan discharge
opens easily and that the impeller turns
freely.
Remove retaining screw and lift off the
terminal box cover (Fig.4).
The installation may be made with the
cable flush fitted by piercing either of the
two notches provided for this (Fig.5.1), or
else with surface wiring, using the side
cable inlet (Fig.5.2).
Insert some 150mm of cable into the
extractor housing and pass it through the
cable clamp.
Fix the extractor to the wall. Arrange the
foam rubber
discharge port so that it fits closely to the
duct. Secure the extractor housing to the
wall by inserting and tightening its
screws.
After wiring is completed, replace
terminal block cover and grille. Turn
on mains supply and check operation.
Electrical connection
The EBB is an extractor designed for a
single phase supply, with voltage and
frequency as indicated on the rating plate
of the unit.
The EBB models are made Class II
(double electrical insulation) 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.
Once the cable has been introduced,
proceed to the appropriate electrical wiring
depending on the EBB model.
EBB models S
Single speed fan. Controlled by remote
switch (e.g. light switch Fig.6 or
independent switch Fig.7) or Auto-
Sensor.
The neon indicator is lit when the fan is
running.

EBB models M
Single speed fan. Controlled by integral
pullcord switch (Fig.8).
The neon indicator is lit when the fan is
running.
EBB models DV
Dual speed and OFF. Low speed running
for permanent "trickle" ventilation / High
speed override / OFF, controlled by integral
pullcord switch, Fig.8. Pullcord switch
sequence – OFF, LOW, HIGH. The neon
indicator is lit when the fan is running.
the
The EBB-250 DV only, may alternatively be
connected for remote switching. The
remote switch (e.g. light switch) will switch
between permanent LOW speed "trickle"
ventilation an HIGH speed override. There
is no OFF position with remote switching.
Use Fig.9 for wiring to a remote switch,
when the integral pullcord switch must be
set for LOW speed and the pullcord cut off
close to the fan.
EBB models T
Single speed with overrun timer. The fan
must be wired to a remote switch (e.g.
light switch, Fig.9 or independent switch
Fig.10). When switched "ON", the fan will
operate at full speed, and will continue
torun for a pre-set time after the switch is
turned "OFF". The timer is factory set at
20minutes. To reduce the operating time,
turn the adjuster in an anti -clockwise
direction, Fig.11.
The neon indicator is lit when the fan is
running.
EBB models HM
The fan contains an integral humidity
sensor. In automatic mode the control
switches the fan on at LOW speed when
the room Relative Humidity (RH) reaches
the set-point. The fan will continue to run
until the room RH falls below the set-
