6 Evacuation system
6.1 Air principle
The fan creates low pressure in the machine, drawing air into the drum via the heating unit.
The heated air passes through the garments and the drum holes.
The air then flows out through a lint filter positioned in the door. After this, the air is evacuated through the fan and ex-
haust system.
Note!
It is very important that the machine gets enough fresh air in order to get the best drying result.
6.1.1
For machines with heat pump
Ventilating the room
When the machine is in operation, the room temperature increases. Due to this, the room must have sufficient
ventilation.
All sources introducing heat into the same room requires to be considered when dimensioning the ventilation. Heat
sources could for example be: more tumble dryers, drying cabinets, washers, ironers, radiators, etc. The combination
of several sources for heat introduction leads to an increased need for ventilation flow. Other factors may also influ-
ence the needed ventilation flow, such as climate zone, building parameters, room size, etc. For assistance with di-
mensioning necessary ventilation needs, contact authorized ventilation technician.
6.2 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 is blown out of the room.
To avoid draught in the room it is important to place the air inlet behind the machine.
Provisions for adequate air supply: The area of the air inlet opening should be five times the size of the exhaust pipe
area. The area of the inlet opening is the area through which the air can flow without resistance from the grating/slat-
ted cover.

Note!
Gratings/slatted covers often block half of the total fresh air vent area. Remember to take this into account.
