Unohab Cavity Wall Installation Kit
The wall sleeve must not be shortened on the inside of the wall, as the cut-out for feeding the power supply cable is
located here (see Fig. 5 & 6)!
When using the deep version external grille (Part no: 90001004), a wall sleeve protrusion of 50mm to the outside of
the wall must be taken into account (see
.Fig. 6)
If necessary, the thickness of the plaster or wall covering should be taken into account.
