Handle
regularly
the
device
valves
in
view
to
avoid
theirs
blocking
on.
If
a
personal
in
charge
of
maintenance
closed
a
blocked
valve,
this
personal
will
must
avoid
the
possible
increase
of
pressure
in
the
part
of
device
which
is
isolated.
The
periodic
technical
checks
must
be
made
following
frequencies
determined
by
standards,
sound
engineering
practice,
end
user
and
installer.
Report
periodic
checks
and
analyze
the
data.
In
case
of
abnormalities
or
inconsistencies,
determine
the
cause
and
correct
it.
In
case
of
hanged
units
(evaporator
as
an
example),
it
is
necessary
to
define
an
exclusion
zone
on
the
ground,
to
avoid
the
presence
of
persona
under
the
equipment.
It
is
important
to
ensure
that
the
hinge
mechanisms
of
moving
parts
are
operational
before
all
manipulations
(drain
pan,
door,
fans
mounted
on
hinges,…).
In
general,
when
opening
any
moving
parts
it
is
necessary
to
accompany
them
or
slow
their
opening
speed
to
avoid
casing
deformations.
Lockable
fan
switch
aren’t
safety
accessories.
RECYCLING
Before
disassembling
all
or
part
of
a
device,
make
sure
that
the
power
supply
has
been
switched
off.
Recover
for
recycling
by
means
of
appropriate
tools
the
refrigerant
present
in
the
unit
or
in
the
area
of
intervention
after
isolation
of
it.
Collect
all
used
oil
and
deposit
it
in
the
appropriate
recycling
centers.
Remember
to
drain
the
oil
separator.
Eliminate
all
or
part
of
the
device
in
a
suitable
recycling
center
