8 Mounting preparations
It is imperative to compensate any uneven-
ness in the wall or ceiling so that the lower
part of the housing can be installed without
warping. Otherwise it may be that the fan
insert can no longer be inserted into the
lower part of the housing or that the de-
gree of protection indicated on the rating
plate is no longer guaranteed.
10.Attach spigot made from shaft material F90
around the shaft.
The spigot compensates for the length of
the shaft walls in the event of a fire.
11.Continue with the safety-related test of the
shut-off device: Electrically connecting the unit
[} 40].
8.4 Preparations for wall, shaft or
ceiling installation without fire pro-
tection
1. Carry out installation preparations as de-
scribed: Requirements in line with approval
[} 29]. However, comply with the specifications
suitable for the exhaust air system in accord-
ance with the applicable fire protection regula-
tions.
2. Permissible connection ducts for connection
without fire protection requirements:
• Shaft/wall installation: Flexible aluminium duct
with DN 80 connection diameter, max. 2 m
long, two 90° elbows.
• Ceiling installation (connection outside of the
shaft): Steel folded spiral-seams duct and/or
flexible aluminium duct with DN 80 connection
diameter, max. 2 m long, two 90° elbows.
3. Use suitable mounting material for installation
without fire protection.
8.5 Preparations for the electrical
connection
DANGER Danger to life from electric
shock.
Before laying the power cable, switch off all sup-

being accidentally switched back on and position
a visible warning sign.
Always note the relevant specifications for
electrical installations and when fitting
equipment. In Germany, observe DIN VDE
0100 and the corresponding parts in partic-
ular.
1. Switch off mains fuse, secure against being
