Installing the appliance
Mounting the air separator
The air separator keeps the supply and
exhaust air separate. This prevents
warm exhaust air from flowing into the
machine, optimizing the energy
performance of the unit.
^ If necessary, shorten the three parts
of the air separator.
^ Insert the foam pieces back into the
sides.

^ Clip the air separator, left and right of

sure that it clicks into place and
guides the foam partition under the
exhaust grille.
