Operation
Case 1: Automatic operation (Fig.9)
In this mode the pull cord switch is enclosed
EN
behind the grille, in the "off" position (The
pilot lamp will not switch on). The hygrostat
causes the extractor to operate automati-
cally 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 gri-
lle 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 connec-
ted 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 le-
vel in the room is higher than the level se-
lected 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. The-
refore, to avoid the fan working continuous-
14
ly, these models must be installed only in
rooms with poor illumination. As an indica-
tion, an intensity of 30 Lux is to low to allow
normal reading ( Fig. 12).

INSTALLATION (Fig. 14)
These models have been designed for insta-
llation 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
6. Outlet
7. Rubber joints
8. Spacers
9. Threaded ring
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 installa-
tion 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 spa-
cers are not needed. Once the above ope-
rations are fi nished, fi x the EDM with the
