before doing any work onpump!
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
voluteand trap are full of water. See priming
instructions, Page 7.
2. Make sure there are no leaks in suction piping.
3. Make sure suction pipe inlet is well below the
waterlevel to prevent pump from sucking air.
4. If suction trap gasket is defective, replace it.
5. Make sure pump is not trying to lift water more
than10' (3m).
6. Make sure suction pipe is at least 2" (51mm) in
diameter.

terminals and at meter while
pump is running. If low, see wiring
instructions or consult power
company. Check for loose

11. Pump may be too hot.
(A)Check line voltage; if less than
90% or morethan 110% of rated
voltage consult a licensed
electrician.
(B) Increase ventilation.
(C) Reduce ambient temperature.
(D)Tighten any loose
connections.
MECHANICAL
12. If suction and discharge piping
are not adequately supported,
pump assembly will be strained. See "Installation", Page 3.
