5. Impacting and pressing the cable is absolutely prohibited. Cable cannot he used for sling. Don't
discretionarily drag the cable while the pump is running, to avoid creepage.
6. The power supply connected with the pump must be assembled with Electricity-leaking circuit breaker,
and the voltage must be controlled within ± 15%of the rated to avoid destroying the motor.
7. Don't touch and move the pump before cut-off the power to keep safe.
8. Be sure that the connection part between plug and cable is far from the water.
9. Be sure that the plug and cable are far from the heat, oil and the sharp.
MAINTENANCE:
………………………………………………………………………………………………………………………………………..
1. Often check cable and duly replace the cable if it is found with fault of fracted, broken etc.
2. After running 2000hrs, please maintenance the pump as per the following steps:
Disassemble pump: carefully check the spare parts easily worn, for example bearing, mechanical seal, oil
seal, "0"ring, impeller etc. And duly replace the spare parts damaged.
Chang oil: take the charge plug of oil chamber out, and inject 10# oil to 70%-80% of the capacity of
chamber (edible earthnut oil is available if no 10# oil).
Air testing: After maintenance, the pump must be tested by air. Inject high-pressure air into the pump
and keep the pressure at 0.2Mpa, it proved to be reliable if no leakage within 5 Minutes.
3. Don't submerge the pump into the water if it isn't started for a long time. Must take the pump out of
the water and clean it and then make anti-rust processing.
FAULT AND SOLUTION:
……………………………………………………………………………………………………………………………..
Fault
Possible cause
Rie
šen
ie
Pump does not
start
1. Too low voltage.
1. Adjust voltage to
±
15% of the rated.
2. Impeller blocked.
2. Remove obstacles.
3. Stator winding burn
up.
3. Repair.
4. Capacitor damaged.
4. Replace capacitor.
5. Absent phase (3
phase).
5. Check switch and cable connection etc.
6. Too large
resistance of cable.
6. Use the proper cable (Item 3 and 4 must be
operated under the guidance of dealer or technician
qualified)
Pump delivers
reduced water
1. High delivery head.
1. Lower the head.
2. Filter mesh clogged.
2. Clean the filter mesh.
3. Impeller worn off.
3. Replace impeller.
4. Too shallow
submersible depth.
4. Adjust the submersible depth above 0,5m
Pump stops
suddenly
1. Switch cut off or
blowout.
1. Check power supply, replace fuse.
2. Impeller blocekd.
2. Shut off power, clean obstacles.
3. Stator winding
burn up.
3. Repair (must consult the dealer and technician
qualified)
