Cleaning
If necessary, clean the AP shutter/SG external grille with a dry cloth. Frequency depends on ambient conditions and anticipated impairments.
For AP...:
- Do not open, close or bend the lamellae too much (lamellae breakage).
Only clean the AP shutters/SG external grille with water and not in the dishwasher.
Do not use aggressive, harmful or easily flammable cleaning agents.
