Troubleshooting Guide, Suction leaks/lost prime

TROUBLESHOOTING GUIDE

Read and understand safety and operating instructions in this manual before doing any work on pump!

Only qualified personnel should electrically test pump motor!

FAILURE TO PUMP; REDUCED CAPACITY OR DISCHARGE PRESSURE

Suction leaks/lost prime:

1.	Pump must be primed; make sure that pump volute
	and trap are full of water. See priming instructions,
	Page 9.
2.	Make sure there are no leaks in suction piping.
3.	Make sure suction pipe inlet is well below the water
	level to prevent pump from sucking air.

Hazardous voltage.

Can shock, burn,

or cause death.

Disconnect power

before working

on pump or motor.

Electrical:

10.Pump may be running too slowly; check voltage at motor terminals and at meter while pump is run- ning. If low, see wiring in- structions or consult power company. Check for loose connections.

11.Pump may be too hot.

A.Check line voltage; if less than 90% or more than 110% of rated voltage consult a licensed electrician.

B.Increase ventilation.

C.Reduce ambient temperature.

4.	If suction trap O-Ring is defective, replace it.
5.	Make sure pump is not trying to lift water more than
	10' (3m).
6.	Make sure suction pipe is at least 2" (51mm) in diameter.
Clogged pipe/trap/impeller, worn impeller:
7.	Make sure suction trap is not clogged; if it is, clean
	trap and strainer.
8.	Make sure impeller is not clogged (follow steps 1
	through 7 under “Removing Old Seal”, Page 11;
	check impeller for clogging; follow steps 7 through
	11 under “Installing New Seal”, Page 11, for
	reassembly).
9.	Impeller and diffuser may be worn. If so, order replace-
	ment parts from Repair Parts List, Pages 13 and 14.

D. Tighten any loose connections.

MECHANICAL TROUBLES AND NOISE

1.If suction and discharge piping are not adequately

supported, pump assembly will be strained. See “Installation”, Page 4.

2.Do not mount pump on a wooden platform! Securely mount on concrete platform for quietest performance.
