Troubleshooting

Read and understand safety and operating instruc-
tions 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 6.
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.
4. Suction lift of 1 to 2 feet (.3-.6M) will reduce perfor-
mance. Suction lift of more than 2 feet (.6M) will pre-
vent pumping and cause pump to lose prime. In
either case, move pump closer (vertically) to water
source. Make sure suction pipe is large enough.
Clogged pipe/trap/impeller, worn impeller:
1. Make sure suction trap is not clogged; if it is, clean
trap and strainer.
2. Make sure impeller is not clogged (follow instructions
under "Removing Old Seal", Page 7; check impeller
for clogging; follow instructions under "Installing
New Seal", Page 8, for reassembly).
3. Impeller and diffuser may be worn. If so, order
replacement parts from Repair Parts List, Page 10.
Inadequate Circulation:
1. Check trap basket; if plugged, turn pump off and
clean basket. Check and clean skimmer basket.
2. Check that gate valves are fully open.
3. Suction/discharge piping is too small.
4. Check and clean pool filter.
5. Check for clogged pipe/trap/impeller, Page 7.
6. Consult dealer/installer or service representative.
Circuit Breaker In Home Panel Trips Repeatedly:
1. Breaker must be of adequate capacity.
2. For GFCI breaker, test according to GFCI manufactur-
er's instructions.
3. Be sure no other lights and appliances are on circuit.
4. Consult dealer/installer or service representative.
5. Voltage too high or too low. See "Voltage", Page 5.
Electrical:
1. Pump may be running too slowly; check voltage at
motor terminals and at meter while pump is running.
If low, see wiring instructions or consult power com-
pany. Check for loose connections.
2. 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.
D. Tighten any loose wiring connections.
3. Motor internal thermal overload protector is open.
Motor runs too hot. Turn power to motor off. Check
for proper voltage. Check for proper impeller or
impeller rubbing.
4. Consult dealer/installer or service representative.
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.
3. Air leak in suction line (bubbles in water returning to
pool). Repair leak. Tighten trap lid.
4. Foreign matter (gravel, metal, etc.) in pump impeller.
Disassemble pump, clean impeller,
follow pump service instructions on Page 8 for
reassembly.
5. Cavitation.
Improve suction conditions.
Increase pipe size.
Decrease number of fittings.
Increase discharge pressure. Reduce flow by throttling
discharge gate valve.
