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).

aTop up the oil with the recommended type and vol-
ume of oil and refrigerant, depending on the work
carried out (see 62A, Air conditioning, Air condi-
tioning: Parts and consumables for the repair,
page 62A-2) .
aCheck there are no leaks using the electronic de-
tector (see 62A, Air conditioning, Refrigerant cir-
cuit: Check, page 62A-7) .
aCheck that the air conditioning system is operating
correctly (see 62A, Air conditioning, Air condi-
tioning: Check, page 62A-4) . WARNING
After injecting dye into the refrigerant, be sure to
indicate this on a label (supplied with the dye
capsule), and the date of the operation.
Position the label so it is visible near to the cold
loop filler valve.

II - REFITTING OPERATION FOR PART
CONCERNED
aRefit:
-the dehydrator reservoir,
-the dehydrator reservoir bolts on the condenser.
aFit:
-the « condenser - dehydrator reservoir » connect-
ing pipe on the dehydrator reservoir,
-the « expansion valve - dehydrator reservoir » con-
necting pipe on the dehydrator reservoir.
aRefit:
-the bolt on the « condenser - dehydrator
reservoir » connecting pipe,
-the bolt on the « expansion valve - dehydrator
reservoir » connecting pipe.
aPosition the air deflector.
III - FINAL OPERATION
aRefit:
-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 refrigerant and oil quantity values before
filling the circuit (see 62A, Air conditioning, Air
conditioning: Parts and consumables for the re-
pair, 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) .
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) . Note:
When replacing the dehydrator reservoir, add 15
ml of the recommended oil to the quantity of oil
recovered.
