check the condition of the joint
Invert two phases of the feeding
line
Clean the pre-filter
Check pipe fittings and suction
tube joints

line
Prevent as much as possible,
elements that produce load loss
Check that the network voltage
corresponds to that on the motor
specification board
Check terminal box connections
Correctly connect cables with
terminal box terminals
Fasten the cable to the terminal
correctly
Modify size of connection cable to
terminal box terminals
