Overview of compressed air reservoirs
Filling the compressed air system from an external source
The entire compressed-air system can only be filled from an external source via the tire inflation connection
1
or via the coupling head/filler connection (see page 90). Filling the brake system with ancillary consumers
(except air suspension) from an external source requires a minimum pressure of 9 bar.
Vehicles with air suspension:
Filling the entire compressed air system requires a minimum pressure of about 10.5 bar.
Separate filling of the air suspension system (see page 90).
Tire inflation connection
The four-circuit protection valve and the compressed
air drier are usually located on the vehicle frame on
the left side.
On semitrailer tractors the four-circuit protection
valve and the compressed air drier may be installed
inside the frame. Detach any covers if necessary.
