Preparing the shutter

Odours may escape from the ventilation channel.

If the installation position is wrong, the plastic shutter will not close leak-tight.

  1. 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.

Before fitting housing, it is essential that the position of the shutter is checked and its function ensured.

For wall installation with air outlet direction (exhaust socket) to the left or right, install the shutter rotated by 90°, see following figures.

Prepare plastic shutter: Air outlet to top, left or right

Wall installation

  1. Upwards air outlet direction: Do not carry out any modifications (factory setting).
  2. Air outlet direction to the left or right: Pull the shutter out of the exhaust socket, depending on the installation position, rotate and reinsert it. Make sure that the shutter is pushed up to stop in the exhaust socket.

As a rule, use the standard installation position with upwards air outlet direction for ceiling installation (factory setting).
