1. FAILURES AND TROUBLESHOOTING METHOD KAM Problem Possible reasons Recommended remedy The fan is not turn on Wrong electrical connection No power supply to the terminal block Using a multimeter instrument check power supply on the terminal block Disconnect the fan from power supply Check the electrical connection reliability in the terminal block circuit breaker and socket Connect the fan following the wiring diagram The motor speed is too low the motor or the impeller blades are jammed Turn the automatic circuit breaker off Rotate the impeller manually and make sure of no foreign objects inside the impeller that disturb the impeller free rotation Loosen the impeller fixing screw and adjust the impeller position on the shaft to exclude jamming tighten the fixing screw Operating temperature of the air supplied from the chimney to the fan is not sufficient to switch the thermal regulator Wrong selection of the ducting network from the chimney to the fan The set temperature at the thermal regulator is too high and it does not generate a signal for the fan switching on Decrease the set temperature threshold level or increase the air temperature supplied from the chimney Install the fan closer to the chimney The automatic circuit breaker starts as the fan is switched on Increased current consumption due to short circuit in the electric circuit re2.
