Due to the higher air flow rates, the exhaust ducting must be laid in such a way that air
flow is not hindered (few bends, short pipelines, well-made connections and transitions
checked for air-tightness). No filters or louvres may be fitted in the exhaust ducting.
The end of ducting leading into the open should be protected against the elements, e.g.,
with a downward facing 90° bend.
During tumble dryer operation, the room must be adequately ventilated.
Room ventilation opening for air intake from the setup room
The minimum dimension of the ventilation opening depends on the cross-section of the
vent pipe.
If the tumble dryer is connected to a central air supply, additional ventilation openings are
normally not needed.

Supply connection for tumble dryers with a central fresh air intake
For steam-heated tumble dryers, having a central fresh air supply reduces lint build-up
around the heater bank.
Removing the protective cover exposes live parts.
Any work on the appliance may only be carried out by qualified personnel while the
power is switched off.
For safety reasons, a plastic or steel pipe must be installed from the tumble dryer's central
fresh air intake over a minimum length of 3 ft. (900 mm). Each joint must be secured with
two screws. The supply air pipe must not extend into the tumble dryer.
