from 60 to 90 % RH ( % relative humidity).
They are fitted with a pullcord switch (IC)
enabling override of the fan when the relative
humidity level in the room is lower than the
set % RH value. A variable % RH rotary switch
on the front of the fan can be adjusted without
removing the grille.
Alternatively, the EDM-H, CH and VMH can
be powered by the light switch in preference
to the pull cord switch.
Operation
Case 1 : Automatic operation ( Fig.9)
In this mode the pull cord switch is enclosed
behind the grille, in the "off" position (The pilot
lamp will not switch on).
The hygrostat causes the extractor to operate
automatically when the humidity level in the
room is higher than the level shown on the
variable rotary switch. Likewise, the extractor
will stop automatically when the humidity
level drops below the selected level.
WARNING: When the extractor is
operating by hygrostat, the red pilot lamp
on the grille of the EDM is not on.
Case 2 : Automatic operation with pull cord
override facility (Fig. 10).
Automatic operation as in case 1 with the
facility to override the hygrostat by means of
the pull cord when the humidity level in the
room is lower than the selected level on the
rotary switchl. When the pull cord is used to
power the fan the red pilot lamp (L) turns on.
Case 3 : Automatic operation with facility to
override by light switch ( Fig. 11)
The operation of the extractor is the same as
in case 2 although, the EDM is connected to
the light switch (IL) instead of the pull cord.
In this case leave the pullcord inside the fan in
the "off" position .
WARNING: When the relative humidity
level in the room is higher than the level
selected on the rotary switch, the
automatic operation overrides the manual
operations (i.e.pull cord or light switch),
that is, the extractor cannot be stopped by
either the pull cord or the light switch.
EDM model EC
This model is equipped with a photoelectric
cell that activates the extractor when the light
intensity is greater than 30 Lux. Therefore, to
avoid the fan working continuously, these
models must be installed only in rooms with
poor illumination. As an indication, an
intensity of 30 Lux is to low to allow normal
reading ( Fig. 12).

EDM-100 M and VM : Fig. 13.
EDM-100 VMH see the explanation for
models H,CH and VMH.
EDM models VM and VMH. Installation
(Fig. 14)
These models have been designed for
installation on window (single or double
glazing) or wall.
1 and 10 : Protection grille
2 : Cable entry
3 : Connection cover
4 : Fixing screw
5 : Connection terminals
For the installation, make a hole of 105 mm
diameter in the glazing or on the wall.
Loosen the screws on the front and back
protection grilles (1 and 10). Loosen the
threaded ring (9) and remove the 4 spacers
(8).
Mount the EDM depending on the installation
requirements so the glass or the wall is
between the two rubber joints (7):
Fig. 5a : All the spacers on the outside
Fig. 5b : All the spacers on the inside
Fig. 5c : Spacers both on the outside and the
inside
When the unit is installed in double glazing or
on a wall, it is possible that all the spacers are
not needed.
Once the above operations are finished, fix
the EDM with the threaded ring, make the
electrical connection and mount again the
protection grilles.
Maintenance
The extractor needs only a periodical
cleaning using a cloth lightly impregnated
with a soft detergent.
