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 [15]. Note permissible
housing installation positions.
3. Correctly attach main ventilation duct [18]
inside the shaft.
4. For fire protection systems, use ceiling
compound. To do this, encase the ceiling
and pour in the material from above.
5. Connect connection duct [18], suitable for
the ER-UP housing, to the main duct and
seal for ventilation.
6. Cut connection duct [19] to length, note a
maximum duct length of 2 m.
