IMPORTANT
Consult the safety and cleanliness advice and
operation recommendations before carrying out
any repair (see Air conditioning: Precautions
for the repair) .
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229or 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
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.
