Troubleshooting; Recycling Information - WITA ADELINO 2.5SAm Serie Installation Und Betriebsanleitung

c) When replacing the No. 10 white food machinery oil for
an oil-filled motor, the motor must be fully filled.
4. If the electric pump is not used for a long time, it should
Notice
not be immersed in the water. The electric pump shall be
placed in clean water and run several minutes to remove
coagulations inside and outside of the pump, after which
the pump shall be dried, subjected to anti-rust treatment,
and placed at dry and ventilated place.

5. Troubleshooting

Before performing any troubleshooting, make sure the pump has been turned off and all moving components have
stopped rotating. Make sure that the pump cannot be turned on accidentally.
Fault
Difficulty in startup
Low water output
Stop running suddenly
Stator winding is burnt out

accessories may be different from those indicated in this instruction manual. Your understanding is really appreciated.
2. The products involved hereinbefore are subject to continuous improvements and changes (including its appearance and
color)without further notice, please in kind prevail.
Cause
1. The supply voltage is too low
2. The impeller is blocked
3. The cable is too thin and the voltage drop is
too high
4. The stator winding is burnt
1. The head is too high
2. The mesh enclosure is blocked
3. The impeller is seriously worn
4. The submersion depth of the electric pump is
less than standard and air is absorbed
5. There is leakage at the outlet
1. The switch is disconnected or the fuse is burnt
2. The impeller is blocked
3. The stator winding is burnt
4. The motor is overloaded and the protector
acts
1. The mechanical seal is damaged and
water leakage happens, resulting interturn or
interphase short circuit
2. The impeller is blocked
3. The electric pump starts frequently or
operates without water for a long time
4. The electric pump makes overload operation
Remedy
1. Adjust the voltage to ±10% of the rated value
2. Correct the part blocked
3. Select a proper cable
4. Re-insert the winding or carry out overhaul
1. Follow the range of head
2. Clear away sundries like water plants
3. Replace the impeller
4. Adjust the submersion depth of the electric pump, which
shall not be less than 5m
5. Add the Teflon tape to the place of thread for sealing
1. Inspect whether the head and the supply voltage used
conforms to the relevant provisions and make adjustments
accordingly
2. Remove sundries
3. Re-insert the winding or carry out overhaul
4. Check whether the impeller is blocked or the voltage is
too low
Do troubleshooting, disassemble the winding and re-insert
the winding as per the concerned technical requirements as
well as immerse and dry the insulating varnish or deliver the
winding to the repair station for repair
