6. DRAIN Switch – OFF.
Keep the switch ON until water cannon or spray
system is used to flow the water mixture. If

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 pond or water
supply.
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.
8. Ensure foot valve remains submerged in water.
