*(Note: Check prime before look-

ing for other

causes. Unscrew

priming plug and see if there is

water in priming hole.)

Pump does not deliver water to full

capacity (Also check point 3

immediately above

Pump leaks around clamp

POSSIBLE CAUSE(S)

1.Disconnectswitch is off

2.Fuse is blown

3.Startingswitchis defective

4.Wires at motorare loose, disconnected, or wired incorrectly

1.Motor is wired incorrectly

2. Voltage istoo low

"1. Pump in new installationdid

not pick up prime through:

a.Improper priming

b.Air leaks

c.Leaking foot valve

*2. Pump has lost prime through:

a.Air leaks

b.Water level below suction of pump

3.Impeller is plugged

4.Check valve or foot valve is stuck

5in closedposition

•Pipes are frozen

6.Foot valve and/or strainerare buried in sand or mud

1.Water level in well is lower than estimated

2.Steel piping (if used) is corroded or limed, causing excess friction

3.Offset piping is too small in size

1.Clamp loose

CORRECTIVE ACTION

f.Be sure switchis on

2.Replace fuse

3.Replace startingswitch

4.Refer to instructions on wiring. Check and tighten all wiring.

['_WARNINGI Capacitor voltage may be hazardous. To discharge capacitor, hold insulated handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch metal screwdriver blade or capacitor terminals. If In doubt, consult a qualified electrician.

1.Refer to instructionson wiring

2.Check with power company. Installheavier wiringif wire size is too small (See Electrical,Pages 5 and 6)

1.In new installation:

a.Re-prime according to instructions

b.Check all connections on suction line c. Replace foot valve

2, In installation already in use:

a.Check all connections on suction line and shaft seal

b.Lower suction line into water and re-pdme. If receding water level in well exceeds suction lift, a deep well pump is needed

3.Clean impeller; see Maintenance

4.Replace check valve or foot valve

5.Thaw pipes. Bury pipes below frost line• Heat pit or pump house.

6.Raise foot valve and/or strainerabove well bottom

1.A deep well jet pump may be needed (over 20 ft. to water)

2.Replace with plastic pipe where possible, otherwise with new steel pipe

3.Use larger offset piping

1.STOP PUMP, tighten clamp nut 1-2 turns. Alternately tighten nut and and tap clamp with mallet to seat O-Ring. Do not overtighten
