14.2 Installing fan insert/exhaust air
element
Fig. 16
The ER fan insert / The Centro exhaust air
element is inserted in recess-mounted
housings ER-UP/G, ER-UPD or ER/UPB
as follows.
1. Switch off mains fuse, secure and fit
warning sign.
2. Remove plaster protective cover [41]
and clean any dirt off the recess-mounted
housing.
3. Ensure that the fan type ticked in the
housing box matches the type to be fitted.
4. Check ease of movement of shut-off
shutter/backflow preventer.
When installed, the shut-off shutter/back-
flow preventer must close automatically.
With ER-UPD and ER-UPB, this must
close automatically when the yoke spring
used is pressed (exception - upwards air
outlet,
chap. 11.5.2).
With ER-UPD and ER-UPB ensure that
the soldered strut is inserted correctly
chapter 11.5.2.
5. Check that the housing floor seal is
correctly positioned and insert properly.
NOTICE
The noise level will increase if the
housing floor seal [13] is fitted
incorrectly. Degree of protection not
guaranteed if housing floor seal [13]
is positioned incorrectly.
The housing floor seal must lie flat and
without any creases in the housing.
