Duct
connections
The
unit
is
mounted
preferably
in
for
example
laundry
room,
storage
room,
utility
room,
etc.
Air
duct
from
cooker
hood
can
be
connected
to
separate
"bypass
channel"
in
the
top
of
the
unit,
marked
“Cooker
hood”.
The
choice
of
placement
must
be
taken
into
account
that
the
unit
requires
periodic
maintenance.
Be
sure
that
it
is
possible
to
open
/
remove
the
unit
inspection
hatch,
and
that
there
is
sufficient
room
to
remove
the
main
components.
If
the
unit
is
mounted
on
the
lightweight
wall
construction
to
the
living
room,
for
example
bedroom
/
living
room,
recommended
wall
insulated
/
constructed
so
that
the
risk
of
sound
transmission
avoided.
Fresh
air
intake
is
to
be
placed
primarily
on
the
building's
north
and
east
and
at
a
good
distance
from
the
exhaust
openings
for
ventilation,
central
vacuum,
Hoods
and
Vents,
sewer
vent,
chimney
or
other
contaminated
source
such
as
dust
/
exhaust
from
traffic
etc.
The
return
of
the
exhaust
air
should
always
be
in
good
distance
from
fresh
air
intakes,
close
windows,
etc

for

there
also
can
be
used
combi
grids
with
inlet
and
outlet
air
are
in
the
same
box.
Air
to
and
from
the
unit
will
be
led
through
the
ducts.
Best
durability
and
capabilities
for
cleaning
will
be
achieved
by
using
ducts
in
galvanized
steel.
Short

with
a
flexible
aluminum
‐
ducts
can
be
used
for
piping
between
the
unit
and
roof
cowl
/
wall
grid.
In
order
to
achieve
effective,
low
energy
consumption
and
proper
airflow,
the
duct
system
designed
with
low
air
speeds
and
low
pressure
drop.
