Safety instructions for the installation of the plastic shutter
It is essential to observe the permissible installation positions: Permitted installation positions:.
Damage to unit, malfunctioning in the event of corrosion damage from mortar.
- Wrap ventilation ducts, connected to the unit, with a suitable adhesive tape to protect against corrosion inside the brickwork, e.g. using cold-shrink tape.
Odours may escape from the ventilation channel.
If the installation position is wrong, the plastic shutter will not close leak-tight.
- Insert shutter at the top/to the right/to the left/to rear in the exhaust socket of the housing to fit the installation position. Ensure that the shutter closes entirely leak-tight.
