I - SAFETY
Refrigerant is heavier than air. As a result there is a risk
of asphyxia for those working close to the ground and
less than 5 m away from the working area (pit, well, air
vents, etc.).
Switch on gas extraction systems.
At temperatures above 100˚C, the refrigerant will de-
compose and produce a highly irritant gas.
II - GENERAL RECOMMENDATIONS
It is possible to place components in the drying oven
after painting or to carry out work near the system if the
temperature does not exceed 80˚C.It is essential to follow the routing of the connecting
pipes.
Ensure that the refrigerant connecting pipes are cor-
rectly fitted so that they will not come into contact with
metal parts in the engine compartment. IMPORTANT
The following must be worn when handling refrige-
rant:
-gloves,
-protective goggles (with side shields if possible).
In the event of refrigerant fluid coming into contact
with the eyes, rinse well with clean water continu-
ously for 15 minutes. If possible, have an eye rinse
unit available.
If refr igerant comes into contact with your eyes,
consult a doctor immediately. Inform the doctor that
the burns were caused by R134A refrigerant.
In the event of contact with other unprotected parts
of the body (event though the safety advice has
been observed), r inse well with clean water continu-
ously for 15 minutes.
IMPORTANT
Work requiring the use of refrigerant must be car-
ried out in a well-ventilated area.
The refrigerant must not be stored in a shaft, a pit,
a hermetically sealed room, etc.
Refrigerants are colourless and odourless fluids.
IMPORTANT
It is forbidden to smoke close to an open refrigerant
circuit.
IMPORTANT
To prevent refrigerant from leaking, never repair a
faulty air conditioning circuit component.
Replace all faulty components.
WARNING
In order to avoid any refrigerant leaks, do not dam-
age (deform, twist, etc.) the pipe.
WARNING
To avoid damaging the surface of the air condition-
ing pipes when removing the seals, do not use a
tool with a metallic end piece.
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which are
open to the air.
WARNING
To prevent any leaks, check that the seal and sur-
face of the pipe are in good condition. The seal and
the surface must be clean and free from scratches.
WARNING
Lubricants are not mutually compatible: always
observe the type and quantity of oil recommended
for each compressor even when topping up as this
could damage the cold loop components.
Always close the oil cans again after use to keep
moisture out and never use oil contained in a can
that has been open for a long time (viscous appear-
ance).

aUse a compressed air nozzle to blow on the sur-
face and the seal of the connecting pipe.
aLubricate the surface of the connecting pipe and the
seal with air conditioning oil (see 62A, Air condi-
tioning, Air conditioning: Parts and consum-
ables for the repair, page 62A-2) .
aRemove the blanking plugs.
II - REFITTING OPERATION FOR PART
CONCERNED
aRefit the compressor.
aConnect the compressor connector.
aPosition the compressor connecting pipes.
aRefit:
-the bolts of the connecting pipes on the compres-
sor,
-the bolt of the connecting pipe bracket on the com-
pressor.
III - FINAL OPERATION
aRefit:
-the accessories belt (see Accessories belt: Re-
moval - Refitting) (10A, Engine and peripherals),
-the front bumper (see Front bumper: Removal -
Refitting) (55A, Exterior protection),
-the front wheel arch liners (see Front wheel arch
liner: Removal - Refitting) (55A, Exterior protec-
tion),-the front wheels (see Wheel: Removal - Refitting)
(35A, Wheels and tyres).
aConnect the battery (see ) (80A, Battery).
aConsult the amount of refrigerant and oil required
before filling the air conditioning circuit (see 62A, Air
conditioning, Air conditioning: Parts and con-
sumables for the repair, page 62A-2) .
aFill the refrigerant circuit using a refrigerant charg-
ing station (see 62A, Air conditioning, Refriger-
ant circuit: Draining - Filling, page 62A-8) .
aIn the event of replacement, apply the after repair
procedure:
-Switch on the ignition,
-Check that the air conditioning is off,
-Switch the ventilation to speed 2,
-Put the temperature setting at minimum,
-Select the air recirculation position,
-Start the engine.
-Run the air conditioning in manual mode (in the
case of climate control do not press auto),
-Run the engine at idle speed for 3 minutes with air
conditioning,
-Switch off the engine.
aCheck for leaks (see 62A, Air conditioning, Refrig-
erant circuit: Check, page 62A-7) .
aCheck that the air conditioning system is operating
correctly (see 62A, Air conditioning, Air condi-
tioning: Check, page 62A-4) .
