Missing power supply
the switches of the thermostat are not in the right position of working
there are foreign bodies that block the rotors.
Check electrical connections
Pression is low than what is required and then the air flow is excessive. It must increase pressure
drops with calibration dampers.
Excessive density of the fluid. Rotation speed too high.

Excessive density of the fluid. Rotation speed too high.
Pressure drop of the system are underestimated.
Cloggings in the air ducts.
Rotation speed too low: verify on the terminal board of the motor that the connection is correct and that
the voltage correspond to that of the nameplate.
the rotor turn backwards.
Excessive air flow.
Air leakage from the duct joints.
Unbalanced fan.
Foreign bodies in the case.
Unbalanced impeller because of wear or of dust deposit.
