EBB CENTRIFUGAL EXTRACTOR
EBB series extractors have been manufactured
according to strict production and quality control
standards such as ISO 9001. All the components
have been verified and all the devices have been
tested following assembly.
We recommend you to check the following points
when you receive this extractor:
1- Make sure you have received the right model
2- Make sure that the data on the nameplate are
appropriate to your needs: voltage, frequency,
speed, etc.
SAFETY RECOMMENDATIONS
The installation must be carried out in
accordance with current regulations in each
country.
- The installation must be carried out by a
qualified professional.
- The electrical installation must incorporate an
omnipolar switch with an opening between
contacts of at least 3 mm, appropriate for the load
and complying with current standards.
- In bathrooms, the device must be installed
outside the reach of any person taking a shower
or a bath and the switch must be installed outside
the bathroom.
- Do not use these fans in explosive or corrosive
atmospheres. If the EBB is working in a kitchen
where there is a boiler or any other kind of
combustion device that needs air to work, check
that the air inlets to the kitchen are sufficient.
- The extractor discharge cannot be connected to
a conduit for the evacuation of smoke from
devices worked by gas or any other fuel
- In the event of considerable humidity, you are
advised to install the discharge conduit
horizontally, with a slight outwards slant.
INSTALLATION
IMPORTANT: Before proceeding with the
installation and connection of the device,
make sure to disconnect the electricity
supply.

EBB series fans must be installed in an area that
-
is sheltered from meteorological conditions; they
can be assembled either in vertical or horizontal
position.
The extractor is designed to be connected to a
-
100-mm diameter conduit
- Before assembling the device, check that the
turbine rotates freely.
For your extractor to work more efficiently:
- Do not use conduits whose diameter is less than
100 mm
- If a flexible conduit is used, stretch it out fully
- Do not place elbows right at the extractor
discharge
- Elbows should have as large a radius as
possible
Surface Assembly (fig. 2A):
1. Make a 105-mm diameter hole in the wall or
ceiling, making sure that the device fits in the area
you have planned for it.
2. Remove the front cover (1) of the fan body (2)
pressing the clips (3) carefully with a small
screwdriver (fig.1B).
3. The fan body (2) is secured to the base frame
(4) by means of 4 screws and 3 flanges. To
dismantle it, remove the 4 screws from the
corners and open the 3 flanges (7) by introducing
a small screw driver through the slots (6).
4. Using 4 screws and plugs that are appropriate
for the kind of wall, fix the base frame (4) on to the
surface, ensuring that the circular profile of the
frame coincides with the opening made, so that
the discharge nozzle can be introduced easily
subsequently.
5. Open the connections cover (5) of the fan
body and pass the cable through the hole
provided for this purpose on the bottom of the
terminal box.
6. Reassemble the fan body (2) on to the base
frame (4) by introducing it into the flanges and
securing it with the 4 screws.
7. Connect to the terminals passing the cable
through as indicated in figure. 3.
8. Follow the electrical diagram applying to the
EBB version that is being installed (fig. 5 to 8).
9. Close the connections cover (5) with the
screw.
10.Assemble the front cover (1) again, pressing
the upper and lower clips and pressing each
corner down to ensure that it fits properly in place.
11.Turn the extractor on to check that it works
properly.
Built-in assembly (fig. 2B):
1. Use the template to mark and cut the panel
into which the device will be installed. Read the
instructions given on the template carefully.
2. Follow steps 1, 2 and 3 of the Surface
Assembly Instructions.
3. With built-in assembly, the discharge can be
directed towards the side (fig. 4). To do this,
remove the discharge flange (3). Cut the
deflector (8) completely and put the discharge
flange back in the desired direction.
4. Open the connections cover (5) and pass the
cable through the hole provided for this purpose
on the bottom of the terminal box.
