REQUIRED
SERVICE
SPACE
Below
are
reported
the
required
minimum
space
for
service
and
maintenance
tasks
on
the
units.
Moreover,
re
‐
circulation
of
discharge
air
has
to
be
avoided;
failure
to
observe
this
point
will
result
in
poor
performance
or
activation
of
safety
controls.
For
these
reasons
it
is
necessary
to
observe
the
following
clearances.
Please
note
that
the
unit
is
designed
in
order
that
the
parts
that
may
require
maintenance
are
accessible
from
the
front
part.
In
any
case
it
is
advisable
to
keep
free
the
encountered
spaces
on
both
left
and
right
side
in
order
to
facilitate
the
removal
of
the
unit
and
maintenance.
In
the
right
side
table
are
shown
the
max
lenghts
of
air
piping
that
should
be
respected.
The
unit
is
self
‐
supporting,
therefore,
it
is
also
possible
to
install
it
on
the
floor
using
the
special
anti
‐
vibration
feet
(NOT
supplied
with
the
unit).
See

If
air
inlet
and/or
outlet
pipes
are
connected,
portion
airflow
and
capacity
in
heat
pump
unit
will
lose.
If
the
unit
connects
with
air
ducts
it
should
be:
DN
120
mm
for
pipes
or
120
mm
internal
diameter
flexible
hose.
The
total
length
of
the
ducts
should
not
be
longer
than
8m
and
the
maximum
static
pressure
should
not
exceed
60
Pa.
If
the
air
ducts
are
bended,
the
pressure
loss
will
be
maximal.
So
if
there
are
2
bending
pipes,
the
total
length
of
the
ducts
should
not
be
longer
than
4m.
Please
note
that
the
performance
of
the
unit
are
reduced
in
the
case
the
air
inlet
is
connected
to
a
duct
which
takes
air
from
outside,
because
of
the
low
winter
temperatures
and
high
summer
temperatures.
The
optimal
working
ambient
temperature
is
20°C.
