If not. adjust
the calibrating screw (marked with
(IIIOW ) so as to obtain the correct level
( within 1.5 mm 1.
b ) Repeot the operation using the << max a) CX tube
in the simulotar jar to check the max. level
in the gauge. 3. Calibrating the gauge :
a) Depress
the oil qauqe pump knob ( 1 1 and
maintain it fully depressed.
When the liquid is stabi!ised in the gouge,
adjust the calibrating screw 1 marked with
arrow ) so that the level indicated on the gauge
is the same as that indicated on the
manual gauge.
b) Release the pump knob
- the level of the liquid should fall below
the min. mark on the gauge.
c) Repeat the adjustment to check that the levels
correspond exactly.

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.
Ill. TIGHTENING TORQUES FOR THE UNIONS IN THE CIRCUIT :
( Oil the union threads with TOTAL LUNARIA 25 before fitting )
On the compressor Intake union : 5/8” 3.45 to 4.3,daNm ( 25 to 31 ft.lb )
Outlet union l/2”’ 2.9 to 3.75 daNm ( 21 to 27 ft.lb )
On the condenser Input union l/2” 4.85 to 5.5 daNm ( 35 to 39 3/4 ft.lb )
Output union : 3/ 8” 2.7 to 3.3 daNm ( 19 l/2 to 23 3/4 ft.lb )
On-de-watering tank : Unions : 3/8” 2.1 to 2.5daNm ( 15 l/4 to 18 ft.lb )
On : Input union evaporator : 3/8” 2.1 to 2.5 daNm ( 15 l/4 to 18 ft.lb )
Output union 5/8” 3.45 to 4.3 daNm ( 25 to 31 ft.lb )

76.54
NOTE This check con only be carried out after having
drained the circuit. If not, dangerous splashing of oil
and refrigerating fluid occur. 0vrs rowed vd. I/,<’
rornprc ‘i YC,l hr ,I,. Yi,,S I,,,, s, /w a) Remove oil filler plug at (S a H and insert into orifice
gauge MR. 630-73/ 15 until it reaches the hottam
of the casing ( rotate crankshaft if necessary 1. The
oil level must be between the min. and max. marks on
the qauqe ( which correspond to a depth of oil of 21
to 29 mm ).
b I If necessary top up using TOTAL (< LUNARIA 25 ),
or SUNISO No.5 01 TEXACO CAPELLA << E )a
grade 500.
c) Remove gouge MR ‘630-73/ 15 and position the plug
with its seal.
3. Create a V(IEYU~ in the circuit :
NOTE This consists in creotinq a vacuum as complete
as possible in the circuit. to eliminate (by evaporation j
any trace of water which
would hinder the operation of
the refrigerating system.
- In the case of replacing the compressor. fully unscrew
screws ( 2 1 and ( 3 1 then screw in screw ( 2 ) two
turns after having connected flexible pipe ( 4) to the
intake valve.
* In other cases see paras. 1 and 2
a) Connect flexible pipe ( 4 i to the intake valve and
flexible pipe ( 6 1 from the vacuum pump to top ( 5 1.
b) Fully unscrew screw ( 3 1.
c ) Open tap [ 5) and switch on vacuum pump. following
the instructions on the S.O.G.E.V.instruction sheet.
di Run pump for a minimum
of 45 mins. Close tap ( 5)
and disconnect pipe ( 6 1 from it.
4. Refill the circuit :
a) Prepare the <( PRESTOGAZ n refill
Unscrew cf Presto-vanneu union ( 7 ) from tap ( 8 1
and connect it to the refill for this. make sure
I forcing if necessary ) that clip on union ( 7) is
fully clipped onto ridge of refill The threaded hole
of the o Presto-vanne )a union must be in line with
the refill valve.
NOTE It is advisable to tighten the clip on the
o Presto-wane >) union. if the union has already
been used for refilling.

NOTE Filling operations on CI vehicle fitted with a and differ from the (< ASPERA-FRIGO 1) compressor only in as much as there are no screws for opening and closing
the valves.
The act of connecting a flexible pipe onto the intake valve (2) of the compressor automatically opens the valve. Checking the oil level on the cc SANKYO ~ncompressor

Disccninect the supply lead from the battery <( + )a
terminal.
e) Insert gouge 6009-T into the freed off passage
The oil level must be between
- the 8th and the 12th graduation ( on vehicle )
( defined by angle aC = 19. on a CX in the
normal driving position ).
- the 6th and the 10th graduation (compressor
removed. and on a horizontal plane ).
Top up if necessary.
f 1 Fit filler plug, and tension belt. Connect iead
from wiring hcrness to clutch.
Fill up with R. 12 fluid if the compressor is on
the vehicle.
