SPECIAL FEATURES
From 1977 models the fast-idle electro-valve ( 9) is manufactured by 1, PIERBURG 1).
When it is not enerqized the electro-valve lets low pressure through towards the carburettor capsule (fast
idle ) contrary to the (1 WEBER )) electromvalve fitted previously.
Fitting the N PIERBURG )) electro-valve necessitates fitting a relay (8) which is enerqized when the air-
conditioning system is operating This relay, with its c( o/)t/i 1) contact cuts off supply to electro-valve (9)
which therefore produces fast idle. DESCRIPTION OF COMPONENTS :

When it is not energized. the electro-valve lets low pressure through to.wards the carburettor capsule (fast-

which therefore produces fast-idle.
The rest of the operation is identical to the preceding diagram. DESCRIPTION OF COMPONENTS :

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).

The oil level must be between

( 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.

Fill up with R. 12 fluid if the compressor is on
the vehicle.

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.
