4.6 Assembling the pressure lines
4.6 Assembling the compressed air lines
Installation and repair guide!
Before assembling the compressed air
lines, the pneumatic circuit must be
depressurised.
The pressure lines to the AirSave Control
Box and the axles must be laid such that
they are protected from damage and
chafi ng.
The line position/length must be selected
such that the lines are not damaged as
the axle extends and compresses.
[1] For axles with air suspension, connect supply
lines (8 x 1 mm PA line) to the AirSave Control Box
directly at the air tank of the trailer air suspension.
In the case of mechanical or hydraulic suspen-
sions, the connection to the brake circuit must
be made with an additional 6.0 bar pressure limit
valve.
[2] Insert reducers (839) into the pressure outlet on
the Control Box.
[3] Unoccupied compressed air outlets must be
sealed using dummy plugs (840).
[4] Remove dummy plugs (834) from the AirSave
T-piece (833).
[5] Insert the compressed air lines into the reducers
on the Control Box and connect to the AirSave
T-piece on the axle.
If the vehicle has other axles, a T-piece must also
be integrated into the pneumatic circuit of each
one, see Figure 14.
No more than 5 axles per Control Box are allowed
to be connected. A second Control Box must be
installed for 6 axles or more.
