PRIOR TO PERFORMING ANY TECHNICAL MAINTENANCE AND REPAIR DISCONNECT THE FAN FROM THE POWER MAINS AND WAIT
UNTIL ITS ROTATING PARTS COME TO A COMPLETE STOP.
The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
Use a soft dry brush or a vacuum cleaner to remove dust. The impeller blades require thorough cleaning once in 6 months.
Detach air ducts from the fan before starting maintenance works. Clean the impeller blades with a soft cloth wetted in mild water
detergent solution. Avoid liquid dripping on the motor and the temperature controller. In case of any problems related to the fan
switching or operation, it is recommended to use a troubleshooting table to eliminate the faults.
