Grounding instruction This appliance must be grounded. In the event of a malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for the electric current. For Canada the dryer comes with a cord which has an equipment grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet which has been properly installed and grounded in accordance with all local regulations and ordinances. d WARNING d Improper connection of the equipment grounding conductor may result in electric shock.

Exhaust ducting which is longer than recommended may extend drying time, cause lint to accumulate and affect dryer performance and dryer lifeĆtime. FourĆinch (approx. 100 mm) diameter ducting should be used. Use either rigid metal or flexible metal ducting material. DO NOT use plastic or nonĆmetal duct with this dryer. DO NOT assemble the ductwork with screws or fasteners that extend into the duct. They will serve as an accumulation point for lint. Joints should be secured with aluminum tape. All joints should be tight to avoid leaks. The male end of each duct section must point away from the dryer. Whether connecting to an existing venting system or a new venting system, make sure that all ducting is clean and free of lint.

plug
must
be plugged
into
an
appropriate

installed
and
grounded
in
accordance
with all
local regulations
and
ordinances.

9.
Do
clean
and
inspect the exhaust
system
on a regular
basis;
at
least
once
a year.
10.
The
exhaust
duct
must terminate
in a manner
to prevent back
drafts
or
entry
of birds or other
wildlife.
The
Bosch
dryers
are
intended
to
be
vented outdoors.
To prevent buildĆup
of
moisture
and
accumulation
of
lint
indoors,
as
well
as
to maintain
maximum
drying efficiency,
it
is
recommended
that
the dryer
is
vented
outdoors.
Exhaust air outlet
on
the
dryer
The dryer
is
delivered
with
an
exhaust
air
outlet on
the rear
of
the appliance.
To
take
account
of
the spatial
requirements
and
an
existing
exhaust
air
system,
the following
connection
options
are possible
for
the exhaust
air
outlet:
-
on right
side of
the appliance,
-
on the underside
of
the appliance.

Ductwork
To
ensure optimum
performance,
the
ducting
system
of
the dryer should be
as
short as
possible
with
a minimum
number of
elbows.
Your dryer
will
work
best
when the venting
system has
as
few air
flow restrictions
as
possible.
Exhaust
ducting
which
is
longer
than
recommended
may extend drying
time,
cause lint
to
accumulate
and
affect
dryer
performance
and
dryer
lifeĆtime.
FourĆinch
(approx.
100
mm) diameter
ducting
should be used. Use either
rigid metal
or
flexible metal ducting
material.
DO
NOT
use plastic or
nonĆmetal
duct
with
this
dryer.
DO NOT
assemble
the ductwork
with
screws
or
fasteners
that extend
into
the
duct. They will
serve as an
accumulation
point for
lint.
Joints
should be secured
with
aluminum
tape.
All joints
should
be tight to
avoid
leaks.
The male end
of
each
duct
section
must point away from the dryer.
Whether
connecting
to
an
existing
venting
system or
a new venting
system,
make sure that all ducting
is
clean
and
free of
lint.
The maximum
permitted
length
for
both
rigid
and
flexible metal duct
is
shown in
the table below.
