the area of the skirt (8) of the reservoir(6)using a cloth, then replace the dryer reservoir (6).
Removing the plastic bracket holding the reservoir (6) :
- Remove the screw (3)(Torx 20), from the bracket assembly/plastic counter-bracket (4)and (5).
- Remove the counter-bracket (5). (Rotate it round the hinge in a clockwise direction).
- Disengage the bracket from the harness(1)(Rotate it round the reservoir (6)anti-clockwise).

Removing the reservoir (6) from the base (8).
WARNING :This operation requires the greatest care, the base(8)should be kept clean prior to fitting
the new reservoir.
- Remove the reservoir (6) and the protection skirt(7), avoiding WITHOUT F
AILany contact or collision
with other items under the bonnet(Risk of impurities entering the base (8)).
- Check before refitting the reservoir (6)that the base(8)is clean.
(If it is not, clean in and around the base(8)with a paper cloth.)
Preparing the new dryer reservoir
- Remove the black plastic protection cap from the reservoir neck (6), leaving in place the green protec-
tion at the other end, in order to keep the new reservoir (6) sealed when mounting it in the base(8)of
the condenser.
- Use the grease sachet in the replacement kit, to lubricate the threads of the reservoir.
- Use the oil sachet in the replacement kit, to lubricate the two O-ring seals of the reservoir (6).
- Position the reservoir(6), with its new protection skirt (7)from the replacement kit, and engage the
threads of the reservoir (6) in the base (8).
- Check that the downward edge of the skirt (7), covers the base(8) all around it.

WARNING :The reservoir (6)contains a drying agent. As soon as the black protection is removed, the reser-
voir must be mounted in the base (8), otherwise there is a risk of damaging the air conditioning circuit.
Screwing the reservoir (6) into the base (8).
- Screw the reservoir(6)manually, until the neck of the reservoir(6) is in contact with the bottom of the
base (8).
- Tighten with a torque spanner and tool [2]at(2)to 1.3 ± 0.1 m.daN.

ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.
SPECIAL FEATURES : AIR CONDITIONING SYSTEM (R 134.a)
Compressor lubricant.
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 PRESSURE valve, 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.a fluid from the system in accordance with the instructions in the equipment handbook.
- Measure the amount of oil recovered.
- Add the same amount of NEW oil when filling the system with R 134.a fluid.
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 NEW oil is left in the compressor as was in the old compressor.
- No more oil should be added when filling the system with R 134.a fluid.

Checking the compressor oil level (continued)
2/ Slow leak.
- Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.
3/ Fast leak.
This type of leak causes both oil loss as well as allowing air to enter the system.
It is therefore necessary to :
- Replace the dryer.
- Drain as much oil as possible (when replacing the faulty component).
Either before or during filling of the system with R 134.a fluid, introduce 80 ccof NEW oil into the system.
