WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which
are open to the air.
WARNING
In order to avoid any refrigerant leaks, do not
damage (deform, twist, etc.) the pipe.
Note:
Use blanking plugs for the fuel circuits with part
no. 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.
