SECTION 4
Normal Operations
4-4
3. Gate Valve – OPEN
4. Cab Control SYSTEM/POWER Switch – ON
5. PUMP Switch – ON
Engaging/disengaging the water pump above
LOW IDLE may result in water pump component
damage and reduced service life.
6. Vehicle RPM – SET
7. Hose Nozzle – OPEN as desired.
Once operations are complete:
8. Hose Nozzle – CLOSE
9. Vehicle RPM – LOW IDLE
10. PUMP Switch – OFF
Engaging/disengaging the water pump above
LOW IDLE may result in water pump component
damage and reduced service life.
11. (If Equipped) Cab Control SYSTEM/POWER
Switch- OFF
12. Gate Valve – CLOSED
13. Hose – Reel in and stow hose nozzle.
SUCTION LOAD STATION
1. Place vehicle near water holding pond.
2. Secure vehicle and make unit safe for exiting cab.
3. Foot Valve – Serviceable
4. Suction Hoses – Inspect suction hoses for
serviceability. Ensure suction hoses are
connected properly to each other and the suction
load inlet to prevent air leaks while in use.
5. Suction Hoses – Immerse in water supply.
The suction loading pump has a maximum
vertical lift capability of 8-10 feet. Attempting to
pump water into the tank from a reservoir that is
more than 8-10 feet below the pump station will
result in reduced suction loading performance.
6. Position all butterfly valves as indicated in the
following pictures and in the order as follows:
a. SUMP VALVE - CLOSE
b. SUCTION VALVE - OPEN
c. SPRAY BAR VALVE - CLOSE
d. TANK FILL VALVE - OPEN
Opening and closing valves in this sequence
allows the water in the suction loading sump
built inside of the tank to flood the water pump
and suction hose. This will allow water pump to
lift water from pond.
7. Ensure water pump and suction hoses are full of
water before operating pump.
Operating the water pump in a dry sump will
result in shaft seal damage.
