Cause Cure
The unit does not
start
F Incorrect electrical wiring.
Have the electrical connection checked by the
Technician, referring to the diagram in the terminal
box.
F Unsuitable supply voltage.
Make sure the supply voltage, measured at the motor
terminals, matches the rated v/-10%.
G The impeller is stuck. Have the unit repaired by FPZ After-Sales Service.
Insufficient or no air
flow
G The suction filter is clogged.
Have the cartridge cleaned or replaced by the
Technician.
G Wrong frequency (for inverter powered units). Correct the frequency.
G
Profile of impeller blades modified (due to
deposits on the profile). Have the impeller checked by FPZ After-Sales
Service
Insufficient or no
differential pressure
F Wrong rotation direction.
Have the rotation direction reversed by the
Technician, switching around the two power supply
wires.
G Leak in the system Find the leak and seal it.
Current absorption
higher than the
permissible value
F Incorrect electrical wiring.
Have the electrical connection checked by the
Technician, referring to the diagram in the terminal
box.
F Supply voltage drop.
Have the supply voltage at the terminals restored
within the permissible values by the Technician.
G The suction filter is clogged.
Have the cartridge cleaned or replaced by the
Technician.
G The unit has accumulated deposits inside.
Have the unit cleaned inside by FPZ After-Sales
Service.
G
The unit is operating at a pressure and/or
vacuum higher than the permissible value. Operate on the system and/or control valve to
decrease the pressure differentials.
High delivery air
temperature
G
The unit is operating at a pressure/vacuum
higher than the permissible value. Operate on the system and/or control valve to
decrease the pressure differentials.
G The suction filter is clogged.
Have the cartridge cleaned or replaced by the
Technician.
G The unit has accumulated deposits inside.
Have the unit cleaned inside by FPZ After-Sales
Service.
G Suction and/or delivery pipes obstructed. Have the obstructions removed by the Technician.
G Intake air temperature above 40°C (+104°F).
Use heat exchangers to reduce the intake air
temperature.
Abnormal noise
F The sound absorbing material is damaged.
Have the sound absorbing material replaced by the
Technician.
G
The impeller rubs against the casing:
- The unit is operating at a pressure/vacuum
higher than the permissible value.
Operate on the system to decrease the pressure
differentials.
- Reduction of assembly play due to internal
deposits (dust, dirt on pipes, process
residues, etc.).
Have the unit cleaned inside by FPZ After-Sales
Service.
G Worn bearing.
Have the bearing replaced by FPZ After-Sales
Service.
F Unit installation position unsuitable.
Have the units installed on structures that cannot
transmit or amplify the noise (tanks, metal plates,
etc.) by the Technician.

Divided as follows: F for functional fault and G for serious fault
ATTENTION!
The unit's bearings must only be replaced:
if all the instructions, parts list, and the section/exploded view of the respective unit are available.
