WARNING
ENTERING THE WATER TANKS CAN BE DANGEROUS,
PARTICULARLY IN HOT WEATHER. PERSONNEL ENTERING
THE TANK ARE SUBJECT TO SLIPS AND FALLS, POOR
VENTILATION, HEAT EXHAUSTION, OR OTHER INJURIES
COMMON TO WORKING IN CONFINED SPACES WITH LIMITED
VENTILATION. NO ONE SHOULD ENTER THE FRESHWATER
TANKS WITHOUT NOTIFYING A COWORKER OR ANOTHER
PERSON FIRST. THE PERSON WORKING INSIDE THE TANK
SHOULD ALSO KEEP THE TRUCK IGNITION KEYS WITH HIM
TO ENSURE THE UNIT CANNOT BE ACCIDENTALLY DRIVEN
WITH HIM OR HER INSIDE. ANOTHER TEAM MEMBER
SHOULD ALWAYS STAY IN CONSTANT COMMUNICATION
WITH THE PERSON INSIDE THE TANK TO ENSURE THEY
ARE SAFE AND BE ABLE TO PROVIDE ASSISTANCE IF
NECESSARY.
Charge Water Pump
The water tanks provide clean fresh water to the
low pressure charge pump. It is powered by the
waterblasting hydraulic system that is activated by
the transmission PTO. The pump delivers a con-
stant supply of water to the Ultra-High Pressure
(UHP) Pump and should maintain a minimum of
at least 40 PSI (2.8 Bar) on the Charge Pressure
gauge in the control panel.
A supply valve located between the clean water
tank and the charge water pump controls the flow
of water. Always make sure there is at least a half
a tank of water and the supply valve is open prior
to engaging the charge water pump. If the charge
water pump is engaged while this valve is closed or
there is no water in the clean water tank, you will
not be able to achieve required UHP pump charge
water pressure and the charge pump impeller or
UHP pump will likely be damaged.
Note:
The UHP pump can cavitate if the charge wa-
ter pressure drops below 25 PSI (1.7 Bar.)
Cavitation can cause severe damage to the
UHP pump and should never be allowed to
occur. You should always monitor the charge
water pressure and never operate the UHP
pump when charge water pressure drops
below 30 PSI (2.1 Bar.)
The charge water pump is activated by engaging
the transmission PTO and pressing the rocker
switch labeled CHARGE PUMP on the control
panel in the cab of the truck. (Refer to Startup
Procedure in the Waterblasting Operation section
of this manual) Once activated, a green light will
