If
devices
are
used
in
a
seismic
area,
then
the
installer
must
apply
all
necessary
rules.
If
the
appliance
is
installed
in
an
area

consideration
of
the
external
fire
situation
is
mandatory,
then
the
installer
must
make
the
necessary
arrangements.
Enough
free
space
all
around
the
refrigeration
equipment
should
be
provided
to
facilitate
maintenance
operations.
The
heat
exchangers
must
be
installed
in
locations
free
of
any
external
dust
or
other
pollutants
from
the
neighbourhood
which
could
obstruct
or
clog
the
coils.
If
devices
are
used
in
a
corrosive
area
(sea
side,
pollutant
gas,
etc.),
make
sure
that
appropriate
anticorrosion
protection
has
been
provided.
Make
sure
that
pipings
are
connected
to
the
appropriate
pressurized
equipment
(EN378-2).
All
connecting
pipings
must
be
correctly
supported
and
clamped.
For
the
connection
of
pipings,
protect
sensitive
components
located
around
the
permanent
assemblies
to
be
made.
Before
any
intervention,
the
operator
must
obstruct
all
the
openings
of
the
circuit
(+
pressurization
under
nitrogen)
;
except
dry
cooler,
brine
air
cooler.
Discharge
pipings
(outlets
of
safety
valve
for
example)
must
be
installed
in
view
to
protect
people
and
apparatus
from
leakage
of
refrigerant.
Make
sure
that
flexible
hoses
are
not
in
contact
with
metal
parts.
The
products
added
for
thermal
and
/or
acoustic
insulation
must
be
neutral
with
respect
to
support
materials.
The
protection
devices,
pipings
and
accessories
must
be
protected
against
unfavourable
effects
from
the
environment.
Make
sure
that
access
and
emergency
exit
ways
are
not
obstructed
to
comply
with
the
local
regulations.
COMMISSIONING
Prior
to
electrically
connect
the
facility,
make
sure
that
the
AC
power
line
voltage
and
frequency
ratings
correspond
to
the
indications
on
the
identification
plate
and
the
power
voltage
is
within
a
tolerance
of
+
10
%
with
respect
to
the
rated
value.
Specific
protection
is
provided
according
to
the
neutral
system.
Any
on-site
wiring
must
comply
with
the
legal
standards
in
force
in
the
country
of
installation
(including
grounding).
Before
turning
on
a
device,
make
sure
that
:
-
the
electric
connections
have
been
correctly
made
-
the
clamping
screws
of
the
various
terminals
are
correctly
tightened
Check
the
possible
presence
of
locking
devices
of
compressor
antivibration
elements,
and
remove
them,
if
they
exist.
.
OPERATING
Do
not
use
the
refrigeration
equipment
or
components
for
any
utilization
other
than
that
for
which
it
is
designed.
Comply
with
the
special
manufacturers’
recommendations
contained
in
the
manufacturers’
operating
instructions.
It
is
strictly
prohibited
while
the
device
is
running
to
remove
the
guards
and
panelling
provided
by
the
manufacturer
to
protect
the
user
and
ensure
his
safety.
When
operating,
surface
temperatures
above
60°C
and
/or
below
0°C
may
be
reached.
During
any
servicing
operation,
the
personnel
should
be
extremely
careful
while
working
on
the
device.
Profroid
is
not
informed
to
real
use
of
partly
completed
machines
;
their
integrations
and
use
must
comply
to
Machines
Directive
and
recommendations
of
this
operating
instructions.
Results
of
design
calculations,
checks,
and
test
reports
in
relation
with
low
voltage
directive
are
archived.
Modifying the setting of the safety valves is absolutely prohibited.
When working on a sealed valve as part of a maintenance operation, it is mandatory to install a new seal immediately after this operation,
making sure beforehand that the valve is returned to its original position.
MAINTENANCE
/
RECYCLING
The
device
must
be
checked
and
inspected
into
service,

approved
personal,
following
rules.
The
device
will
be
subject
to
preventive
maintenance
(EN

:
-
external
visual
inspection
of
device,
-
checks
of
device
during
running,
-
checks

device
corrosion.
Before
working
on
pressurized
components,
shut
down
the
facility
and
wait
until
the
equipment
is
at
the
ambient
(room)
temperature.
Before
removing
the

valve
must
be
made
by
the
same
brand
of
