PRECAUTIONS
TO
BE
TAKEN
WHEN
WORKING
ON
THE
AIR-CONDITIONING
SYSTEM
a) It is
imperative
to wear goggles
b ) Do not smoke
R 12 fluid,in
the presence
of a flame turns
into a toxic
gas.
c) Never heat any section
of the refrigerating
system.
d) Never
switch
on the refrigerating
system
if both electric
cooling
fans are not connected
e ) Never check
the compressor
oil level
without
first
having
drained
the refrigerating
circuit.
f ) Never use any oil other than TOTAL
(( LUNARIA
25 H, SUNISO
No 5 or TEXACO
CAPELLA
(( E 1) grade
500
g ) Never use refrigerating
fluid
other than R.12.
NOTE
Refrigerating
fluid
may- be sold under different
names : FORANE
(( 12 )), FLUGENE
(( 12 ))! FREON
((12 ))
( the most important
feature
is the number
(( 12 H which
defines
the fluid's
properties
).
IMPORTANT
NOTES
A. The compressor
MUST
NEVER
b e switched
on when the circuit
has been drained
of its refrigerating
fluid.
during
work 'being
carried
out in the workshop.
for example,.
Indeed,
in these
conditions,
the
compressor
would
be functioning
in air, and would
deteriorate
rapidly.
'Consequently,
in case of an exchange
of compressor
necessitating
draining
the system
of its refrigerating
fluid,
in a workshop
not equipped
with
the necessary
equipment
for refilling
( SOGEV
equipment
)
IT
IS
IMPERATIVE,
before
driving
the vehicle
to another
workshop
equipped
with
the special
equipment.
to carry
out the following
- To
leave
the
blanking
plugs
on the
compressor.
in order to avoid
ingress
of air ( the new compressor
contains
refrigerating
fluid
).
- To blank
the
intake
and
outlet
hoses
and
to fix
them
tempororily.
- Todisconnect
the
supply
lead
to the
electro-magnetic
compressor
clutch
( lead with
white
sleeve
).
NOTE
: We remind
you that if the circuit
has been in contact
with
the atmosphere,
it is necessary
to replace
the de-watering
tank, and the compressor
oil.
B. Slight
oil seepage
is permissible
at the front bearing
of the air-conditioning
compressor.
Compressors
showing
such
a seepage,
and
being
replaced
OS a result,
will
not
be accepted
under
warranty.
