8.Make sure the shaft is clean.

9.Clean the face of the rotating part of the seal with a soft cloth. Dip the assembly in a soap solution or clear water and push onto the shaft, with the sealing face first, until the square rubber drive ring is completely on the shaft shoulder.

10.Screw the impeller on the shaft until its hub is against the shaft shoulder. This automatically positions all seal parts properly.

TROUBLESHOOTING

1.PUMP WON’T DELIVER ANY WATER

Review priming instructions. Make sure the pump and suction line are full of water.

2.LOSS OF PRIME

a)Check the suction line and foot valve for leaks. The entire suction side of the system must be totally air tight.

b)Make sure the water level hasn’t dropped enough to uncover the suction inlet. Sufficient pipe would be used to prevent this from happening.

3.LOW FLOW OR PRESSURE

a)Check suction piping for leaks.

b)Check the impeller for clogging. Remove all foreign material if it is clogged.

4.NOISE

a)Make sure pump and piping are supported.

b)Make sure suction lift does not exceed 20 ft.(6mm)

c)Check disch. piping for excessive bends or elbows.

d)Check motor bearing for damage.
