Fresh-air
For maximum efficiency and the shortest
possible drying time, it is important to ensure
that fresh air is able to enter the room from the
outside in the same volume as that blown out
of the room.
To avoid a draught in the room, it is advisable
to place the air inlet behind the machine.
The area* of the air inlet opening must be 5
times the size of the vent pipe area.
The resistance in the grating/slats on the air
inlet cover plate should not exceed 10 Pa
(0.1 mbar).

*The area of the inlet opening is the area
through which the air can flow without
resistance from grating/slatted cover.
Note that gratings/slatted covers often block
half of the total fresh air vent area. Remember
to take this into account.
