3.7 Venting
When the TRUCK BOOSTER
is properly connected to sup-
ply water, electrical installation
and a high-pressure hose (or
pipeline) the high-pressure
pump must be vented before it
is operational.
1. Turn the main switch, (2
)
to
position “ON”.
2. Push the “START” but-
ton (3), and the TRUCK
BOOSTER will start.
3. Open the outlet point (spray
handle on high-pressure
hose, (c) or outlet on piping
system (d) without having a
spray lance connected.
4. Let the water run until all air
has escaped from the pump
(even water fl ow).
5. In the case of a recently
installed piping system,
or if the pipeline and the
pump have been emptied in
any other way, the system
should be vented by starting
the pump and then letting
the water run at each outlet
point of the pipeline at turns.
It is recommended to begin
with the most distant outlet
(height and/or length).
6. When connecting the high-
pressure hose directly to
the machine, starting the
pump and activating the
trigger of the spray handle
without having attached the
spray lance, should vent the
system.
7. Stop the TRUCK BOOSTER
by pressing the “STOP” push
button (4).
The TRUCK BOOSTER is now
vented.
