during
installation,
troubleshooting
and
maintenance,
pipes
may
not
be
used
as
steps:
the
pipe
could
break
under
the
weight,
spilling
refrigerant
and
possibly
causing
serious
burns,
when
servicing
the
appliance,
the
composition
and
state
of
heat
carrying
fluid
must
be
checked,
as
well
as
the
absence
of
any
refrigerant,
during
the
annual
unit
sealing
test
in
accordance
with
applicable
legislation,
the
high
and
low
pressure
switches
must
be
checked
to
ensure
that
they
are
securely
fastened
to
the
coolant
circuit
and
that
they
cut
‐
off
the
electrical
circuit
when
tripped,
during
maintenance
work,
ensure
there
are
no
traces
of
corrosion
or
oil
around
cooling
components,
before
beginning
work
on
the
cooling
circuit,
stop
the
device
and
wait
for
a
few
minutes
before
fitting
the
temperature
and
pressure
sensors.
Some
elements
such
as
the
compressor
and
piping
may
reach
temperatures
in
excess
of
100°C
and
high
pressures
with
the
consequent
risk
of
severe
scalding.

-
the

This
data
must
be
recorded
in

Recycling
This
symbol
means
that
your
device
must
not
be
thrown
in
the
bin.
The
device
must
be
collected
by
a
selective

Any
substances
it
may
contain
which
are
potentially
dangerous
to
the
environment
shall
be
eliminated
or
neutralised.
