VII. WIRING DIAGRAMS FOR COOLING FAN AND AIR-CONDITIONING SYSTEM CONTROLS
7.; 1976 - Special features :
From 1977 models, the fast-idle electro-valve ( 9) is manufactured by (( PIERBLJRG )).
When it is not energized. the electro-valve lets low pressure through to.wards the carburettor capsule (fast-
idle ) I contrary to the (( WEBER )) electro-valve fitted previously.
Fitting the (( PIERBURG )) electro-valve necessitates fitting a relay (8) which is energized when the air-
conditioning system is operating. This relay with its N open )) contact cuts off supply to electro-valve ( 9)
which therefore produces fast-idle.
The rest of the operation is identical to the preceding diagram. DESCRIPTION OF COMPONENTS :
1
- Heater relay ( standard )
2 - Air blower ( Stmdnrd )
3 - Speed control for blower f Stnudnrd )
4 - Regulating thermostat
5 - Air-conditioning switch
6 - Pressure switch ( on dc-wnkrivg t~rrk ,)
7 - Compressor cl.utch
8 - Control relay for fast-idle electro-valve
9 - Fast-idle electro-valve
10 - Relay f0r’L.H. supplementary electric fan ( air-rorzditio)litlg J 11

- Control thermostat ( on radiator ) for electric fans ( Standard ) 14
- Relay for R.H. electric fan ( Stmzdurd 1

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).

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)

This device entails modifying the following components
- Heater distribution box ( outlets towards side vents unplugged, different radiator )
Side vents with twin outlets ( ambient or heated air )
Addition of Westaflex ducts ( link from heater distribution box to side vents ). III. WATER TEMPERATURE GAUGE
The presence of a water temperature gauge entails modifying the following components :
- water pump spacer ( addition of a temperature sensor )
steerinq column surround ( location of temperature gauqe )
- engine harness for warning lamp senders ( addition of lead from temperature sensor to front wiring harness )
addition of a temperature sensor and a temperature gauge.
