7.7 ER-UP/G ceiling installation,
second room
1. Note installation information: Installation in-
formation.
2. Mount housing on ceiling as described:
G ceiling installation, single room [
.
3. Mount ER-ZR second room connection set on
Secure housing and the connection duct
with 2 mounting supports and/or clamping
bands/ threaded rods each.
7.8 Installation of ER-UPD housing
The following are not permitted:
• Second room connection with an ER 60 fan in-
sert (all models).
• Second room connection in combination with
Centro exhaust air elements.
• Connecting a WC odour extraction unit in com-
bination with Centro exhaust elements.
• Use of an ER fan or Centro exhaust air element
in the bathroom or toilet room, if other rooms in
the apartment are to be vented with the same
unit at the same time.
7.9 Installation information for ER-
UPD housing
(also
Requirements in line with approval [
and approval)
ER-UP/G are equipped with a plastic housing
without fire protection equipment. The ER-UP/D
housing may be installed in the following installa-
tion positions:
They can be installed with an air outlet direction
(exhaust socket) upwards, to the right or left and
are suitable for ceiling installation. With an up-
wards air outlet direction, the yoke spring should
be removed from the shut-off device.
A description of ceiling installation in a suspended
ceiling can be found below. In the case of non-
suspended ceilings, the housing is mounted dir-
ectly on the ceiling.
Wall installation should be undertaken as de-
scribed for ceiling installation. Suitable mounting
material is to be provided by the customer. To
screw down the connection duct use steel
screws, if screwing into brickwork/concrete use
steel dowels.
The metal shut-off device should be pre-
pared according to these instructions.
The ER-UPD housing must be inserted
without any distortion
. Failure to do so will
mean that the fan insert cannot engage correctly
in the ER-UPD housing and the degree of protec-
tion stated on the rating plate is no longer en-
sured.
Break open one of the housing segments [S] to
use the second room connection set ER-ZR.
Use ER-MO expanded rubber for acoustic insula-
tion of thin ceilings capable of resonance.
A toilet seat air extraction unit is connected to the
ER-UPD housing using the DN 70 extraction
socket ER-AS.
7.10 Important information about
plastering
• Minimum overlap required for the ventilation
shaft (without tiles, etc.) in the area of the con-
nection duct 10 mm.
• Max. compensable plaster overshoot 7 mm.
• Max. protruding housing edge 20 mm, can be
compensated for with spacing frame DR
60/100.
• 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.
• Joints between the housing and wall can be
covered with cover frame ER-AR.
We recommend keeping these installation
and operating instructions until final installa-
tion in the housing.
