Purge/Prime
The truck is equipped with an innovative purge/prime
system that strokes the water pump the full extent of the
stroke. This aids in removing unwanted air while in work
mode. When winterizing the jetting system, the purge
feature aids in removing water from the pump.
The prime feature is activated by placing the truck in
“ready to jet” mode.
This is accomplished by:
1.
Run the engine, make sure the water supply line
valve (1), located on the driver’s side under the front
of the debris body, is open.
Figure 4-5
2.
Place the truck in WORK mode on the cab control
panel.
3.
Make sure the ENGINE SPEED and WATER
PRESSURE dials located on the front control panel
are set to their minimum settings (fully
counterclockwise). See Figure 4-1.
NOTE
The system may be primed with the sewer hose
secured in the travel fitting on the hose reel or after
the hose has been placed in the sewer.
4.
Press VAC (2) on the front control panel MODE
switch.
Figure 4-6
5.
Turn the water pressure dial up slowly to the blue
purge/prime setting and until movement of the pump
(LVDT) (3) is observed on the second screen of the
front control panel display (HMI).
Figure 4-7
6.
If the engine RPM increases and the stroke of the
LVDT shortens, the water pressure dial has been
advanced too far into the normal operation zone.
Decrease the dial setting until LVDT movement
resumes on the display. Stroking the pump several
times should yield the desired results.
