IMPORTANT
To avoid all risk of damage to the systems, apply
the safety and cleanliness instructions and opera-
tion recommendations before carrying out any
repair:
- (see 62A, Air conditioning, Air conditioning:
Precautions for the repair, page 62A-1) ,
- (see Vehicle: Precautions for the repair) (01D,
Mechanical introduction).
Note:
Use blanking plugs for the fuel circuits with part no.
77 01 208 229 or 77 01 476 857 to plug any open-
ings exposed to the open air. They must be clean.
Do not use any which have already been used to
plug a fuel circuit.
WARNING
Consult the device's operating manual to avoid
incorrect use.

WARNING
In order to avoid any refrigerant leaks, do not
damage (deform, twist, etc.) the pipe.
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which
are open to the air.
WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.

aClean the surface and seal of the pipe using EN-
GINE CLEANER (see Vehicle: Parts and con-
sumables for the repair) (04B, Consumables -
Products).
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
