• Always note the relevant specifications for elec-
trical installations and when fitting equipment. In
Germany, observe DIN VDE 0100 and the cor-
responding parts in particular.
• Observe ambient conditions (Environmental
conditions and operating limits [}10]) and
technical data (Technical data [}10]).
• Observe permitted duct cross-section of max.
1.5mm².
1. Lay power cable to the installation location.
2. Continue with the safety test of the release
device: Preparing the shutter [}16].
6.5 Preparing the shutter
NOTICE Odours may escape from the ventila-
tion channel.
If the installation position is wrong, the plastic
shutter will not close leak-tight.
Insert shutter at the top/to the right/to the left/to
rear in the exhaust socket of the housing to fit the
installation position. Ensure that the shutter
closes entirely leak-tight.
Before fitting housing, it is essential that
the position of the shutter is checked and its
function ensured.
For wall installation with air outlet direction
(exhaust socket) to the left or right, install the
shutter rotated by 90°, see following figures.
Prepare plastic shutter: Air outlet to top, left
or right
Wall installation
1. Upwards air outlet direction: Do not carry
out any modifications (factory setting).
2. Air outlet direction to the left or right: Pull
the shutter out of the exhaust socket, depend-
ing on the installation position, rotate and rein-
sert it. Make sure that the shutter is pushed up
to stop in the exhaust socket.
As a rule, use the standard installation position
with upwards air outlet direction for ceiling in-
stallation (factory setting).

and push with the 4 bayonet hooks (at rear) to
the right into the slots right up to stop.
5. Push the 4 push buttons into the housing
holes on the upper side of the housing at posi-
tions [Y]. These must audibly engage.
NOTICE If the air exhaust socket is installed
incorrectly, the function of the unit is im-
paired.
Ensure that all locking bolts and push buttons are
engaged and that the socket is flush with the
housing.
6. Check for correct installation of the exhaust
socket.
7. Insert the shutter into the exhaust socket as
described in the Left air outlet direction in-
stallation position: Preparing the shutter [}16].
6.7 Conversion of air outlet adapter
for air outlet towards rear
5 Spiral housing
6 Air outlet adapter: Air outlet above (factory
setting)
7 Air outlet adapter: Air outlet at rear
For air outlet direction to the rear, replace
the air outlet adapter with the curved air out-
let adapter.
Replacement
1. Loosen the 2 locking tabs of the exhaust
socket and carefully pull it out of the spiral
housing rearwards.

2. Push the exhaust socket into the slot on the
spiral housing until it audibly engages with the
two locking tabs.
3. Check and secure correct connections.
7 Housing installation
7.1 Installation of ER GH housing
The following are not permitted:
• Use of an ER EC fan in the bathroom or toilet
room if other rooms in the apartment are to be
vented with the same unit at the same time.
7.2 Installation information
(also Requirements in line with approval [}12])
ERGH housing without fire protection device.
Installation is permissible in the following posi-
tions:
•Wall installation With air outlet direction (ex-
haust socket) upwards, to the right, to the left or
to the rear. Installation with UPM 60/100 mount-
ing support or directly with the wall with ER-MS
installation kit (hammer head screws and brack-
ets) in the side mounting grooves.
•Ceiling installation and suspended ceiling:
Installation with UPM 60/100 mounting support
or directly with the ceiling with ER-MS installa-
tion kit (hammer head screws and brackets) in
the side mounting grooves.
•Ceiling installation and non-suspended ceil-
ing: Mounting directly on the ceiling.
Suitable mounting material is to be provided by
the customer.
The plastic shutter should be prepared ac-
cording to these instructions so that it closes
fully sealed in the installation position.
The housing must be inserted without any dis-
tortion. Failure to do so will mean that the fan in-
sert cannot engage correctly in the housing and
the degree of protection stated on the rating plate
is no longer ensured.
Break open the housing segment [S] below to use
the ER-ZR second room connection set or the
ER-AS extraction socket.
A toilet seat air extraction unit is connected to the
housing using the ER-AS extraction socket
(DN75/80).
Use ER-MO expanded rubber for acoustic insula-
tion of thin ceilings capable of resonance (System
and accessory components [}26]).
7.3 Important information about
plastering
• Max. compensable plaster overshoot 7mm.
• Installation at a depth of 50 to 100mm can be
compensated for with the two-part wall frame
ER-MR.
• The gap remaining between the housing and
shaft must be fully sealed with non-flammable
materials that are resistant to deformation so
that incorrect air is not drawn in.
Recommendation: Keep these installation and
operating instructions until final installation in the
housing.
