Please note
If H
≤
400 mm, the housing must be extended for this arrangement. If ERK-SO are arranged next to each other with horizontal
axis, the heads of hexagon screws must be countersunk. The ERK-SO must always be filled with mortar. If the wall thickness is >
100 mm, always check whether the housing needs to be extended on the b side (MS) - see page 6 Table 2 - (the available wall
thickness and a possible connection to the smoke extraction duct must be taken into account).
