Cleaning
1. Follow item 1 under
Inspection
.
2. Wipe the fan impeller blades to remove any coatings. Use a mild, alkaline
detergent.
3. The external surfaces of the motor must be kept clean. Remove any dust,
dirt and oil. Clean with a dry cloth. In the event of stubborn dirt, use a mild
alkaline detergent. The motor is likely to overheat inside if thick layers of dirt
prevent air from entering the motor to cool the stator structure.
4. Vacuum clean inside the unit so that particles will not be blown out into the
duct system.
5. Clean the other parts in the same way as the fan impeller. Check that the
inlet cones are securely mounted.
6. Follow item 9 under
