7. Open the ball valve on the test tool and observe the engine
tachometer. Engine speed should increase to about 1,800 to
2,200 RPM.
8. Close the air valve slowly to allow the system pressure to rise.
9. Once the system pressure is at maximum, slowly open the ball
valve on the test tool until the pressure on the gauge begins to
drop. Engine speed should start to ramp-up when air pressure
drops to approximately 140 psi.
6.5 Auxiliary Air Receiver
If you intend to use an auxiliary air receiver with this
system you must observe the following installation
procedure to prevent damage to the system
.
The line from the VMAC
tank to the auxiliary air receiver must have a
one-way check valve installed (part #3600078) to prevent blow back
from the auxiliary tank to stop moisture from entering the VMAC tank
(Figure 6.2).
The line to the auxiliary tank must not be installed in the bottom of
the tank, but must be installed as high as possible to prevent water
from entering the line.
Install the line as high as
possible, NOT on the
bottom of the auxiliary tank
