BLEEDING AND FILLING THE BRAKING SYSTEM (Continued)
With the bleeding apparatus.
Connect the bleeding apparatus [1]on the brake fluid reservoir (1).
Adjust the apparatus pressure to
2 Bars.
For each circuit:
Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container.
Open the bleed screw, wait until the fluid is flowing out without air bubbles.
Close the bleed screw.
Remove the bleeding apparatus
[1].
Check the brake fluid level
(should be between «MINI»level and «MAXI»level).
Fill if necessary with the approved and recommended synthetic brake fluid.
Without the bleeding apparatus.
NOTE:Two operators are necessary.
For each circuit:
Apply the brake pedal to place the circuit under pressure.
Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container. Open the bleed screw, wait until the fluid is flowing out without air bubbles.
Close the bleed screw.
Remove the tool
[1].
NOTE:Recommence the process a second time if that is necessary.
Check the brake fluid level
(should be between «MINI»level and «MAXI»level).
Fill if necessary with the approved and recommended synthetic brake fluid.

SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)
Compressor lubricant
ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.
Checking the compressor oil level
There are three specific cases:
1/
Repairs to a system without leaks.2/Slow leak.3/Fast leak.
1/ Repairing a system without leaks.
a)Using draining/recovery equipment not fitted with an oil decanter.
Drain the system as slowly as possible via the LOW PRESSUREvalve, so as not to lose any oil.
No more oil should be added when filling the system with
R 134.a fluid.
b) Using draining/filling equipment fitted with an oil decanter. Drain the R 134.afluid from the system in accordance with the instructions in the equipment handbook.
Measure the amount of oil recovered.
Add the same amount of
NEWoil when filling the system with R 134.afluid.
c) Replacing a compressor. Remove the old compressor, drain it and measure the oil quantity.
Drain the new compressor (supplied full), so that the same amount of NEWoil is left in the compressor as was in the old compressor.
No more oil should be added when filling the system with R 134.afluid.

AIR CONDITIONING SYSTEM R 134.a
Testing procedure
Conditions inside the vehicle.
Positions of the air conditioning controls:
Maximum cold.
Maximum blower power.
Air distribution on
«ventilation»with the air vents open.
Position the air inlet flap to outside air.
WARNING:For RFTA (1), disconnect the air inlet motor connector, first
ensuring that it is in the outside air position.
(1) RFTA= Fully automatic air conditioning.
Test procedure.When all these conditions are met, proceed in the following order:
Measure the temperature in the workshop approx. one metre in front of
the vehicle’s air inlet grille.
Start the engine
(without the air conditioning, or the blower, operating)and wait for the cooling fan slow speed to trigger (should the engine tem
perature not rise sufficiently, it is permissable to increase the engine
speed to 2000 rpm)
.
Once it is sufficiently hot in the engine compartment, return the engine
to idle and commence the test.Switch on the air conditioning and adjust the engine speed to
2500 rpm.
In an ambient temperature of 40°C, the engine speed will be brought
down to 2000 rpm, in order for the pressure safety threshold to cut off the
compressor.
For further temperatures/pressures: see Tables and Graphs on following
pages
221, 222 and 226.
After
3 minutesof operation, note down the following 3 parameters:
The temperature of the blown air coming out of the 2 central air vents
(take the average).
The high pressure, via the intermediary of the clickfit union (at the
pressure reducer inlet).
The low pressure, via the intermediary of the clickfit union (at the pressure
reducer outlet).NOTE:The low and high pressures are absolute pressures.
When measuring the blown air temperatures, avoid any contact between
the thermocouple and the air vents.
