Spray Bar
The Spray Bar is controlled by the spray bar valve. Open
the main tank valve and close the bypass valve.
Start the engine and increase to full throttle. Open the spray
bar valve. Use the pickup/tractor speed to control the rate
that water is applied. The amount of water flowing through
the spray bar can be controlled by partially closing the
spray bar valve or slightly opening the bypass valve. Do
not close the main tank valve. Pump damage can result.
The spray bar covers a maximum swath of 25’. Common
uses include controlling dust on roads or pre-wetting areas
to help prevent spread of fire.
Operation -- Fire Control
In order to fill the tank with the transfer pump close the main
tank valve and attach the fill hose to the suction manifold
(500/800 gal.) or quick-fill coupler (1,025 gal.). Open the
bypass valve on the discharge manifold (500/800 gal.) or
bypass valve (1,025 gal.). Set the end of the fill hose in the
pond, tank or other water source with the suction screen
coupled to the end of the hose. Be sure that the suction
hose bibb is closed. A partially open bibb will let air into
the suction manifold, causing cavitation in the pump and
a lack of pressure.
