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).

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.
