EDM Axial Extractors
The EDM range extractors have been
manufactured to the rigorous standards of
production and quality as laid down by the
international Quality Standards ISO 9001. All
the components have been checked and all
the final products have been tested at the end
of the manufacturing process.
We recommend you to check the following
when receiving this product :
- That it is the correct model.
- That the details on the rating label are
those you require: voltage, frequency ...
The installation mus be in accordance with
the electrical standards in force in your
country.
Installation
IMPORTANT
: Before installing and wiring the
EDM, ensure that the main supply is
disconnected.

The EDM can be installed on wall or ceiling,
and the discharge can be made direct to the
outside or to a ducting ( indivifual or shunt,
Fig. 2).
The hole to be made on the wall or the ceiling
must have the following diameter 105 mm. If
the installation is made to an individual
ducting, use standard ducting 100 mm.
Loosen the screw (4) fixing the grille (1). Bind
the adhesive tape supplied around the outlet
(6).
Ensure that there are no obstructions to the
airflow and that the impeller turns freely.
The unit must be fixed in such a way that it is
not stressed, to avoid noise generation or
problems in the rotation of the impeller.
Connect the electrical wiring as explained
hereafter and then mount the protection grille
and fixed it by tightening the screw (4).
Electrical connection
The EDM 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 made 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 be introduced to the
EDM through the slot (7) if the wire is within
the wall, or through the cable entry (2) if the
installation is with a surface mounted cable;
in this case, the cable must be introduced as
shown on Fig.3.
Once the cable has been introduced, open
the connection cover (3) and proceed to the
appropriate electrical wiring depending on
the EDM model. Then close the connection
cover.
EDM models S and C
For these models use the following diagrams:
Fig.5 : Switching the extractor through the
light switch.
Fig.6 : To switch the fan through an
independent switch.
EDM models T,CT,R,CR and EC
Models fitted with fixed
T and CT) or
adjustable
timer enables the extractor to continue
running during the time delay, after the switch
has been switched off. The diagram on Fig. 7
shows how to connect a unit fitted with timer
using the light switch.
WARNING : Models T and CT require a few
second delay before the extractor
operates.
Models R, CR and CE have an adjustable
timer.
To adjust the timer, turn the potentiometer on
the Printed Circuit Board (Fig. 8) :
- To increase the time delay turn it Clockwise
(CW).
- To decrease the time delay turn it Counter
Clockwise (CCW).
EDM models C,CT,EC,CR,CH and M
These models are fitted with automatic
shutter.
WARNING: The opening of the shutter is
facilited by means of a thermal system
that needs some seconds to open
completely.
EDM models H, CH and VMH
Models H, CH and VMH are provided with an
electronic hygrostat which can be adjusted
not adjustable timer
(R,CR and EC). The
