B. VEHICLES FITTED WITH A SANI(Y0 COMPRESSOR
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
(11 After having made’swe, the compressor contains
no R. 12 under pressure, remove filler plug ( 1).
b) Slacken compressor belt
cj Disconnect the supply lead to the clutch, from the
wiring harness. and connect it to the battery<, + >)
terminal.
d) Rotate the clutch in order to line up mark ,< a ))
( visihlc~ tllrou~h Ihv /i/ler

Then make a mark on the clutch and the compressor
co-sing. and then rotate the clutch by opproximotely
110’ ( clockwise seen from pulley end ).
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.
g) If the compressor is to be put into store. rechange
with R. 12 fluid at o pressure of 0.5 bar (7.25psi)
