DSEH200301.01.EN
Continuous product development may give rise to specification changes without notice.
Cleaning
1. Follow the safety instructions and paragraph 1 under
Check
.
2. Wipe the fan impeller blades to remove any coatings. Use an environmentally
friendly degreasing agent.
3. The external surfaces of the motor must be kept clean from dust, dirt and oil.
Clean with a dry cloth. In the event of heavy soiling, use an environmentally
friendly degreasing agent. 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 the unit so that dust is not blown out into the duct system.
5. Clean the other parts in the same way as the fan impellers. Check that the
inlet cones are securely mounted.
6. Refit the fan unit and earth braid.
Resetting the overheat protection
1. Cut the power supply to the fan motor.
2. Wait at least 20 seconds after the fan impeller has stopped rotating.
3. Close the power supply to the fan motor.
