Non-return flap
Use a non-return flap in the exhaust
system.
A non-return flap ensures that when the
cooker hood is not in operation, the
duct is closed to prevent unwanted
exchange of room air and outside air.
If the exhaust is ducted through an
outside wall, a Miele wall vent or roof
vent (available as an optional
accessory) is recommended. Both of
these have a built-in non-return flap.
If the on-site ventilation system does
not have a non-return flap, one is
supplied with the cooker hood.
The non-return flap is fitted in the
exhaust socket of the fan.
Condensation
If the exhaust ducting is to run through
cool rooms or ceiling space, for
example, the significant variations in
temperature between the different areas
can cause condensation to form.
Insulate the exhaust ducting to reduce
temperature variations.
If the exhaust ducting is to be laid
horizontally, it must be laid with a
downwards sloping gradient of at least
1 cm per meter. This is to ensure that
condensation cannot drain back into
the cooker hood.
12062340-01
In addition to insulating the exhaust
ducting, it is advisable to also install a
condensate trap for collecting and
evaporating any potential condensation.
Condensate traps for 125 mm or
150 mm diameter exhaust ducting are
available as optional accessories.
When installing a condensate trap,
ensure that it is positioned vertically
and as closely as possible to the cooker
hood above the exhaust connection.
The arrow on the casing indicates the
direction of airflow.
Miele shall not accept warranty claims
for any functional defects or damage
caused by inadequate exhaust
ducting.
