II. 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.
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 )
