Cause
Incorrect electrical wiring.
Unsuitable supply voltage.
The impeller is stuck.
The suction filter is clogged.
Wrong frequency (for inverter powered units).

deposits on the profile).
Wrong rotation direction.
Leak in the system
2 - 3
Cure
Have the electrical connection checked by the
Technician, referring to the diagram in the terminal box.
Check the power supply voltage. Tolerance of fixed
voltage value ± 10%.
Have the unit repaired by FPZ After-Sales Service.
Have the cartridge cleaned or replaced by the Technician.
Correct the frequency.
Have the impeller checked by FPZ After-Sales Service
Have the rotation direction reversed by the Technician ,
inverting the two power supply wires and leaving the earth
connection unchanged.
