Mounting Pump
CAUTION
•Ensure tank being used is clean and free of welding slag.
•Ensure the tank has a vent to allow air into the tank as the herbicide is being pumped out. Failure to vent tank will cause priming problems.
1.Apply herbicide compatible sealant to large thread on bung adapter (9) (2 in. x
2.Assemble suction tube sections by applying PVC cement (supplied with your pump) to the inside diameter of the PVC couplers. Make sure PVC cement is applied to the complete inside diameter and slide the pipe sections into the coupler with a twisting motion.
For tanks deeper than 36 in. (914 mm) you will
need a standard 1 in. (25 mm) pipe with 1 in. npt threads on one end. Suction tubes longer than 60 in. (1.52 m) require a foot valve (Graco Part No.
260217) at the bottom of the tube to prevent loss of prime.
3.Cut the suction tube so that it is 2 in. (55 mm) from the bottom of the tank when installed in the tank.
4.Insert inlet gasket (7) into union nut (1k). Apply a herbicide compatible sealant to the threads on the
suction tube assembly (5c) and screw the suction tube into the pump inlet (1j).
5.Insert suction tube attached to pump through bung adapter (9) into tank. Position pump as desired and tighten union nut (1k) on bung adapter (9).
Mounting Hose and Nozzle
1.Apply herbicide compatible sealant to male threads on the street elbow fitting (1e) and screw fitting into the 3/4 in. npt outlet port on the top of pump. Do not over tighten.
2.Apply herbicide compatible sealant to threads on both ends of the hose assembly. Screw one end of hose into the female thread on the fitting (1e) and tighten.
3.Screw nozzle onto the other end of hose and tighten.
Electrical Installation 12 VDC
To install wiring for a negative ground system:
1.Ensure pump switch is OFF.
2.To remove electrical cover (2a), remove four bolts (2c).
Power cable can be cut to shorter length if 18 feet 
(5.5 m) is not required. Cut to proper length and proceed with steps 3 and 4.
3.Strip 3 in. (76 mm) of outside insulation from power cable (6c) from end opposite of fuse.
4.Strip 3/8 in. (10 mm) of insulation from red and black wires.
5.Slide strain relief (6b) over end of power cable (6c) on the end just stripped. Male thread of strain relief should be toward stripped end.
6.Insert power cable through conduit thread in electri- cal cover (2a). Connect wires from power cable to wires from the motor using wire nuts (2e): red to red and black to black.
