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
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.
