Only qualified personnel should electrically test
pump motor.
DISCONNECT POWER TO MOTOR BEFORE
WORKING ON PUMP. Close suction and dis-
charge gate valves.
PUMP LOSES PRIME / SUCTION LEAKS
1. Make sure there are no leaks in suction piping. Trap
lid cover must be air tight.
2. Inspect trap O-ring for cuts or nicks. Replace if neces-
sary. Lubricate with petroleum jelly before installa-
tion.
3. Make sure suction pipe inlet to pump is well below
water level to prevent pump from sucking air.
4. Replace suction trap gasket if defective.
5. Suction lift of 8 - 10' (2.4 - 3m) will reduce perfor-
mance. Suction lift in excess of 10' (3m) will prevent
pumping and cause pump to lose prime. Move pump
closer (vertically) to water source. Check size of suc-
tion pipe.
PUMP DOES NOT OPERATE
1. Check and clean suction trap, impeller, fittings, or
trap strainer.
2. Check and clean pool filter.
3. Check for worn impeller or diffuser and replace.
4. Make sure gate valves are fully open.
5. Suction piping is too small.
6. Motor internal thermal overload protector is open.
Motor runs too hot. Turn power to motor off. Check
for proper voltage.
7. Check GFCI for proper operation according to GFCI
manufacturer's instructions.
CIRCUIT BREAKER TRIPS REPEATEDLY
1. Breaker must be of adequate capacity.
2. For GFCI breaker, test according to GFCI manufactur-
er's instructions.
3. Make sure no other appliances or lights are on circuit.
4. Make sure there is only one GFCI on the circuit.
MECHANICAL TROUBLES / NOISE
1. Make sure suction and discharge piping are sup-
ported.
2. Securely mount pump on concrete platform for qui-
etest performance.
3. Air leak in suction line. Repair leak and tighten trap
lid.
4. Check and clean debris in pump impeller.
5. Cavitation -
Remove suction flow restrictions.
Increase pipe size.
Decrease number of fittings in suction piping.
Reduce flow by throttling discharge gate valve.
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 electri-
cian.
B. Increase ventilation.
C. Reduce surrounding temperature.
D. Tighten any loose 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 im-
peller rubbing.
4. Consult dealer/installer or service representative.
