Figure 5. Gun assembly and nozzles.
Slurry Nozzle. The slurry nozzle is an adjustable deflector-type nozzle for spraying slurry. Rotating the
outer knurled portion of the nozzle body (two pieces) adjusts the angle of the orifice-and-deflector
assembly, which varies the spray pattern. The slurry nozzle is shown in Figure 5.
Fire Hose Water Nozzle. The fire hose water nozzle is an adjustable sleeve-type nozzle. The water
nozzle is used to project a straight stream or a fog pattern of water. One-half of the water nozzle rotates
clockwise or counterclockwise to increase or decrease the width of the spray pattern. The fire hose
water nozzle is shown in Figure 5.
Fire Hose Foam Nozzle. The nonadjustable fire hose foam nozzle is used to discharge fire-
extinguishing foam liquid. The fire hose foam nozzle is shown in Figure 5.
The connections for attaching inlet and outlet hoses to the pump are located on the connector panel at
the back of the pump unit assembly. A suction hose connector and the upper and lower discharge hose
connectors are located on this panel. The location of the connector panel is shown in Figure 6 below.
Prime Detergent Tank and Lid
The prime-detergent tank consists of a rectangular, 10-gallon tank in the pump unit assembly and a lid.
The tank has an integral pipe in the bottom and an opening in the top and is used to store water,
detergent, or foam-forming liquid. It is also used for priming the pump. The lid prevents foreign
objects from entering the prim detergent tank. It has two plastic knobs and a steel cable about 12.5
inches long attached to it. One end of
