4.2.2 Wall opening
Before erecting the rotary agitator, the customer must make a hole in the wall for both
the trough of the discharge screw and the rotary agitator duct.

β
The dimensions of the hole are calculated from the wall thickness (s) and the angle of
the trough to the wall (β) or the angle of inclination (α) of the entire system.
Experience indicates that an opening of 500 mm x 500 mm is sufficient.
NOTICE! Do not fix the trough to the wall!
NOTICE! Line the hole in the wall with a flexible material!
⇨ See "Seal the hole in the wall" [page 33]
Rotary agitator duct
α
≥ 200mm
≤ 270mm
The dimensions of the hole depend on the system’s angle of inclination (α). Therefore:
▪ Round hole: Ø min. 250 mm / max. 270 mm
▪ Square hole: Side length min. 200 mm / max. 270 mm
NOTICE! Do not fix the rotary agitator duct to the wall!
NOTICE! Line the hole in the wall with a flexible material!
