Caution!
Risk of poisoning
If other appliances are operated in
the room where the appliance is
installed or in adjoining rooms, e.g.
gas-fired heating systems, gas-fired
boilers, coal-fired ovens connected
to a chimney, or open fireplaces, a
vacuum may be created, leading to
waste gases being sucked back.
Note:
In every case, have safe
operation confirmed by the
responsible chimney sweep, boiler
engineer, ventilation specialist, etc.
Installing more than one dryer
Up to 7 exhaust air dryers can be
connected to an intercepting pipe with a
smooth internal wall.
Note:
The following points must be
observed:
■
It is imperative that there are drain
check valves in the interception pipe
for every dryer. These valves prevent
the moist exhaust air from flowing
back into the washing and drying
room through dryers which are not in
operation.
■
The outlet for the exhaust air must
be arranged/routed in such way as
to prevent any additional
backpressure (e.g. from a direct
ingress of wind) on the escaping
exhaust air.
■
In every case, have safe operation
confirmed by the responsible
ventilation engineer/installer.
When connecting to the interception
pipe, avoid the following:
■
mutual interference between dryers
■
discharge of moisture in the washing
and drying room
■
higher pressure losses (increase in
energy consumption and time)
■
The exhaust air ducts of the
individual dryers (DT = R >=
100 mm) should already be
extended to the dimension of the
interception pipe upstream of the
drain check valves.
■
Possible backpressure (e.g. caused
by wind ingress) can be minimised
by using a 90° bend, facing down.
