1. Check the electrical connections, switches or relays, and the circuit breaker or fuses.
2. Ensure that the motor turns freely by hand.
3. Check that rotation speeds V1, V2 and V3 are not programmed at 0rpm. If they are, restore the factory settings.
RSTRT is displayed during attempts to start.
, check
1. The cables, connections, relays etc.
: The motor on your pump is fitted with a thermal protection which, in the case of overload, will automatically cut the
circuit and avoid the motor being damaged. This triggering is caused by abnormal usage conditions which need to be
checked and corrected. The motor will restart without any intervention as soon as normal operating conditions are restored.
1. Check that the motor shaft turns freely
2. Check that no debris is preventing the turbine from rotating freely
3. Check that the motor is correctly ventilated
4. After correcting the problem, press the On/Off button
1. Ensure the strainer housing is filled with water, that the cover seal is clean and correctly positioned and that no air can
enter. If necessary, tighten the cover lock screws.
2. Ensure that all the suction and discharge valves are open and not blocked and that the suction outlets in the pool are
fully submerged.
3. Check that the pump draws by freeing the suction as close as possible to the pump:
a) if the pump does not draw despite being sufficiently full of priming water
1. Tighten the bolts and pipe accessories on the suction side.
2. Check the voltage to ensure that the pump is rotating at the correct speed.
3. Open the pump and check that nothing is blocking it inside,
4. Replace the mechanical shutter.
b) If the pump is drawing normally, check the suction pipe and strainer which may be blocked or be allowing air to enter.
check
1. That no air is entering the suction side and causing dull crackling in the pump.
2. That there is no cavitation caused by insufficient diameter or a restriction in the suction tube. An over-sized discharge
pipe can also cause cavitation. Use pipes of the correct size or purge the pipes if necessary.
3. That no vibration is occurring due to incorrect fitting.
4. That there are no foreign bodies in the pump housing.
5. That the motor bearings have not seized due to excessive clearance, rust or prolonged overheating.
