Operation To Operate Fan Use an ON/OFF switch to operate this ventilator. Cleaning and Maintenance To Clean For quiet and efficient operation, long life and attractive appearance, remove Grille and vacuum interior of unit with a dusting brush attachment. The Motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the Control Assembly and Motor. XB50 n XB80 n XB110 Installation Guide Troubleshooting Symptom: The fan does not run. • Check for an open fuse or circuit breaker in the building’s service panel. • Check that the two (2) plug-in connections for the Motor and the Control are seated firmly in place. • Check that the Blower Wheel spins freely. Symptom: The fan runs erratically. • Check that the Blower Wheel is firmly attached to the Motor shaft and both spin freely. Symptom: The fan seems noisy. • Check that the back draft damper in the fan’s Duct Connector pivots freely. Screws used to attach the duct to the Duct Connector may be preventing the damper from opening. • Check that the back draft damper in the wall or roof cap pivots freely. These dampers are sometimes mistakenly painted shut or obstructed by bird and insect debris..
