Installation and Operating Instructions
NOTE
Wall stone – KWL 45-160 WS/WS-L
– When installing two or more ventilation units
The following minimum clearances must be observed when positioning two or more ventilation units or wall stones to
prevent short-circuiting (see Fig. 3).
All dimensions in mm
4 .1 Installation
The wall stone must be flush with the uncovered wall on the internal and external sides of the wall.
If necessary, the wall stone must be shortened to the corresponding length.
The wall stone core acts as a stabiliser. Only remove the wall stone core after completion of the wall or installation
of the wall installation sleeve!
Position the wall stone in the wall with the slot facing downwards.
The slot in the wall stone must be oriented downwards so that the connection cable can subsequently be passed
through the empty conduit and the slot (see Fig. 4).
