MAINTENANCE
/
RECYCLING
The
device
must
be
checked
and
inspected
into
service,
regularly,
by
a
qualified
and
approved
personal,
following
rules.
The
device
will
be
subject
to
preventive
maintenance
(EN
378)
:
-
external
visual
inspection
of
device,
-
checks
of
device
during
running,
-
checks
of
devicecorrosion.
Before
working
on
pressurized
components,
shut
down
the
facility
and
wait
until
the
equipment
is
at
the
ambient
(room)
temperature.
Before
removing
the
guards
and
panelling,
turn
off
the
device.
Set
it
aside
and
make
sure
that
no
power
is
present.
Do
not
use
piping
to
access
on
the
equipment
or
to
store
something
on
the
equipment.
The
replacement
of
a
safety
valve
must
be
made
by
the
same
brand
of
the
original
one.
If
there
is
modification
of
type
and
/or
brand,
then
the
professional
in
charge
of
the
replacement
will
do
a
calculation
sheet
following
EN
13136
and
/or
ask
Profroid
some
elements.
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
isisolated.
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
theequipment.
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
