Installation
If the on-site vent system does not have
a non-return flap, one is supplied with
the ventilation hood.
The non-return flap is installed in the
exhaust socket of the fan.
Condensate
If the ducting is to run through cool
rooms or ceiling space, for example, the
significant variations in temperature
between the different areas can cause
condensate to form. Insulate the ducting
to reduce temperature variations.
If the ducting is to be laid horizontally, it
must be laid with a downwards sloping
gradient of at least ³/₈" (1 cm) per meter.
This is to ensure that condensate
cannot drain back into the ventilation
hood.
In addition to insulating the ducting, it is
advisable to also install a condensate
trap for collecting and evaporating any
potential condensate.
Condensate traps for 5" (125 mm) or
6" (150 mm) diameter ducting are
available as optional accessories.
32
When installing a condensate trap,
ensure that it is positioned vertically
and as closely as possible to the
ventilation hood above the exhaust
vent. The arrow on the casing indicates
the direction of airflow.
Miele will not accept warranty claims
for any functional defects or damage
caused by inadequate ducting.
Reducing Collar
(optional accessory)
If you would like to reduce the
environmental impact of your ventilation
system by limiting the CFM output the
Reducing Collar can be installed. It
reduces the air flow to less than
400 CFM. Check local building codes
for max. CFM requirements.
Push the Reducing Collar on the
exhaust port of the blower.
Push the exhaust hose over it.
Secure both with a hose clamp.
