MAINTENANCE
AND
PERIODICAL
CONTROLS
WARNING:
All
the
operations
described
in
this
chapter
HAVE
TO
BE
CARRIED
OUT
BY
TRAINED
STAFF
ONLY.
Before
any
operation
or
before
entering
the
inner
components
of
the
unit,
be
sure
that
the
power
supply
is
disconnected.
The
compressor’s
head
and
discharge
piping
are
usually
at
high
temperature
levels.
Be
very
careful
when
operating
in
their
surroundings.
Aluminium
coil
fins
are
very
sharp
and
can
cause
serious
wounds.
Be
very
careful
when
operating
in
their
surroundings.
After
maintenance
operations,
re
‐
install
the
cover
panels,
and
fix
them
by
means
of
screws
where
necessary.
WARNING:
The
unit
should
be
installed
so
that
adequate
clearance
is
available
for
maintenance
and
repairation.
The
warranty
does
not
cover
costs
related
to
platforms
or
handling
equipment
necessary
for
any
maintenance.
The
refrigerant
circuits
must
not
be
filled
with
different
gas
other
than
that
indicated
on
the
nameplate.
The
use
of
a
different
refrigerant
can
cause
severe
damage
to
the
compressor.
It’s
forbidden
to
use
oils
other
than
those
specified
in
this
manual.
The
use
of
a
different
oil
can
cause
serious
damage
to
the
compressor.
It
is
recommended
to
set
a
lower
temperature
to
decrease
the
heat
release,
prevent
scale
and
save
energy
if
the
outlet
water
is
sufficient.
It
is
a
good
rule
to
carry
out
periodic
checks
in
order
to
verify
the
proper
operation
of
the
unit:

months
Check
the
water
supply
and
air
vent
frequently,
to
avoid
lack
of
water
or
air
in
the
water
loop.
Be
sure
that
the
tank
is
always
filled
with
water.
x
Check
out
that
safety
and
control
devices
work
correctly.
x
Check
out
possible
oil
leakage
from
compressor.
x
Check
out
possible
water
leakages
from
the
hydraulic
circuit.
x
Check
out
the
proper
working
of
the
external
flow
switch
(if
it
is
installed).
x
Clean
the
metallic
filters
of
the
hydraulic
circuit
to
keep
a
good
water
quality.
Lack
of
water
and
dirty
water
can
damage
the
unit.
x
Clean
the
finned
coil
of
the
heat
exchanger
by
means
of
compressed
air
(it’s
recommended
to
keep
the
unit
in
a
place
where
it
is
dry
and
clean,
and
which
has
good
ventilation).
x
Check
the
correct
operation
of
the
electric
heater
for
the
purpose
of
anti
‐
Legionella
cycle(*).
Be
sure
to
make
a
diagnosis
with
samples
of
water
token
from
the
critical
points
the
whole
hydraulic
circuit.
x
Check
out
that
all
the
terminals
on
the
electric
board
as
well
as
on
the
terminals
of
the
compressor
are
properly
fixed.
x
Make
sure
the
electrical
components
are
good.
If
there
is
a
damaged
part
or
a
strange
smell,
please
replace
it
in
time.
x
Tightening
of
water
connections.
x

x
Check
each
part
of
the
unit
and
the
pressure
of
the
system.
Replace
the
defect
part
if
there
is
any,
and
recharge
the
refrigerant
if
it
is
required.
x
Check
the
operating

ENVIRONMENTAL
PROTECTION
According
to
the
norms
dealing
with
the
use
of
depleting
stratospheric
ozone
substances,
it
is
forbidden
to
release
refrigerants
fluids
in
the
atmosphere.
They
have
to
be
collected
and
delivered
to
the
seller
or
to
proper
gathering
points
at
the
end
of
their
operating
life.
Refrigerant
R134A
is
mentioned
among
controlled
substances
and
for
this
reason
it
has
to
be
subjected
to
the
mentioned
norms.
A
particular
care
is
recommended
during
service
operations
in
order
to
reduce
as
much
as
possible
any
refrigerant
loss.
This
equipment
contains
R134a
refrigerant
in
the
amount
as
stated
in
the
specification.
Do
not
vent
R134a
into
the
atmosphere:
R134a,
is
a
fluorinated
greenhouse
gas
with
a
Global
Warming
Potential
(GWP)
=
1430.
It
should
only
be
serviced
or
dismantled
by
professional
trained
personnel.
