aCheck, and if necessary replace, the refrigerant cir-
cuit pipe seal.
aClean the surface and the seal of the pipe using EN-
GINE CLEANER (see Vehicle: Parts and con-
sumables for the repair) (04B, Consumables -
Products).aUse a compressed air gun to blow the surface 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-9) .
aRemove the blanking plugs.
II - REFITTING OPERATION
aProceed in the reverse order to removal.
aConsult the refrigerant and oil quantity values before
filling the circuit (see 62A, Air conditioning, Air

IMPORTANT
Consult the safety instructions and cleanliness
advice and the operation recommendations before
carrying out any repairs (see Air conditioning:
Precautions for repair).
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which are
open to the air.
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229 or 77 01 476 857 to plug
any openings 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
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.
