WARNING
AN IMPROPERLY INSTALLED DEB RIS B AG MAY N OT
RELEASE PROPERLY DURING DUMPING. THIS CAN CAUSE
THE LINER TO SEPARATE FROM THE DEBRIS TANK,
DAMAGING THE TANK AND/OR CAUSE SEvERE INJURY TO
PERSONNEL. ALWAYS MAKE SURE THE DEBRIS BAG IS
INSTALLED PROPERLY AND THAT ALL PERSONNEL STAY
WELL CLEAR OF THE TRUCK AND DEBRIS TANK DOOR
WHEN DUMPING OPERATIONS ARE UNDERWAY.
Dirty Water Drain System
Filtered wastewater is usually clean enough to
dump in swales alongside the road, vacant fields
and designated areas at airports. It should never
be dumped directly into lakes and ponds or any
standing water. Always check with the authorities
to ensure you are dumping within local guidelines.
The operator can choose to drain wastewater di-
rectly to the ground by opening ball valves on each
side of the sump or to the wastewater bladder by
activating the transfer pump system.
Wastewater Transfer Pump
The transfer pump circuit is activated by the DIRTY
WATER switch in the cab control panel. When the
circuit is activated, a pump will transfer wastewa-
ter from the cage sump to the wastewater bladder.
The operator can choose to operate the system
in NORMAL mode, which controls the pump auto-
matically or DISCHARGE mode, which allows the
operator to override the automatic float switch and
manually operate the pump. The transfer pump
mode is selected using the NORMAL/DISCHARGE
switch on the driver side of the cage.
When NORMAL mode is selected, an automatic
float switch controls the water level in the cage
sump by activating the pump and moving waste-
water from the sump to the wastewater bladder.
The automatic float switch is mounted on the
side of the sump. When wastewater in the sump
reaches a predetermined level, the float switch
will activate the pump. The float switch will drop
when the water level is lowered and automatically
turn off the pump.
When DISCHARGE mode is selected, the auto-
matic float switch is bypassed. The pump will con -

tinue to run until the switch is manually returned
to the NORMAL position. The discharge flow from
the pump must be continuously monitored while
operating the system in DISCHARGE mode and the
switch set back to NORMAL mode when pumping
is complete. To avoid damage to the pump, always
return the mode switch to NORMAL as soon the
cage sump is empty and never leave the switch
in DISCHARGE mode.
The debris water pump is a heavy duty, diaphragm
pump. It is protected from large debris that could
damage the pump by an in-line strainer on the
intake side. The strainer canister is equipped with
a valve for back flushing or draining the canister.
The screen should be removed and cleaned pe-
riodically or if it becomes clogged. Another valve
near the pump can be used to purge air from
the pump if necessary or to drain the system for
winterizing. Always make sure the DIRTY WATER
PUMP switch is in the OFF position when cleaning
or back flushing the strainer. Refer to the General
Maintenance section of this manual for instructions
on cleaning or back flushing the strainer.
The sump water level and pump out system must
be monitored periodically during operation and
cleaned as necessary. It is important that the
DIRTY WATER PUMP switch is turned ON just be -
fore the water blasting system is activated and
turned OFF when water blasting operations stop.
