Suppose you intend to install your unit into a wall made of 2N

hollow bricks. Note that the external side of the bricks gets damaged by cutting and
the dowels cannot practically be fixed into the thin internal part of the bricks.
Therefore, use the brick flush mounting box and follow the instructions included
therein.
Wall Mounting
Wall (surface) mounting is used where flush mounting is inapplicable (in concrete and
steel structures, entry barrier columns, etc.). The frame is not used.
Caution
Wall mounting may be a problem where vandals may destroy the unit (in
public garages, e.g.). Therefore, use steel fixing elements instead of the
dowels and screws included in the delivery.
Be sure to insert plugs into unused bushing holes to avoid water leakage
during facade cleaning, for example. Never leave the holes open for even
a short time (one day delay between mounting and cable connection,
e.g.).
