Mounting instructions
● Note approval  chapter 7.1.
● Be sure to use duct materials suitable for
the ER-UP housing  items [18] and [19].
● For fire protection systems, the gap
remaining between the connection duct and
brickwork/wall boards/wall/ceiling must be
fully sealed with non-flammable materials
11. Installation preparations
resistant to deformation (e.g. concrete,
cement mortar, fire protection filler).
NOTICE
Damage to unit, malfunctioning in the
event of corrosion damage from mortar.
 Ventilation ducts connected to the unit
must be wrapped with a suitable adhe-
sive tape to protect against corrosion
inside the brickwork, e.g. using cold-
shrink tape.
Preparing the shaft
1. Produce opening in shaft or alternatively
produce a wall facing. Ensure a suitable,
flat surface for the ER-UP housing so that
the fan insert can be safely inserted in the
housing later on.
2. For a second room connection, produce
an opening in the wall or shaft for the
suction duct [9]. Note permissible housing
installation positions.
3. Correctly attach main ventilation duct [18]
inside the shaft.
4. Fit ceiling compound for fire protection
systems. To do this, encase the ceiling
and pour in the material from above.
