There are two ways required the hole for mounting appli-
ance can be drilled in the wall, namely:
A hole with a diameter of Ø280 mm at right angles
through the wall,
A hole with a diameter of Ø260 mm at an angle of 3 °.
WALL THICKNESS BETWEEN 500 MM AND 600 MM
(with wall thickness between 300 mm and 500 mm go to
point 3)

Cut wall sleeve at length X.
X = Y + 34 mm
Example
Wall thickness = 535 mm
Cut length = 535 + 34 = 569 mm
