•
Follow the safety rules for working on electrical products.
•
Secure the main switch against reactivation with a padlock when working on the
product.
•
All work on the electrical mains and on live parts must only be performed by an elec-
trician.
NOTE
Possible material damage caused by incorrect fan rotation direction
If the rotation direction is incorrect, the product heats up unacceptably.
The volume increases, the airflow volume falls, and the product’s suction performance
deteriorates.
Damage to the product cannot be ruled out.
After first switching on the product, the fan impeller’s direction of rotation must be
checked.
1. Turn the product off at the main switch.
2. Compare the rotation speed of the fan impeller with the rotation direction arrow on
the housing.
- If the motor fan wheel is turning in the wrong direction, the motor must have its
electrical polarity reversed.
3. Turn the product off at the main switch.
4. Have the phases of the phase reversing connector transposed by an electrical tech-
nician.
5. Switch on the product at the main switch.
