functions of the controls are described in the operating instructions for the controls.
Manual operation
Blinds are operated using an articulated crank.
Use
• The external venetian blinds meet the requirements of the wind classes indicated in the declaration of conformity and may
remain extended only up to the specified wind class.

Cleaning
The air contains minuscule solid particles, such as dust, rust, and aggressive substances including salt and kerosene, which
encourage corrosion and have a negative impact on how the blinds function. External venetian blinds are equipped with
various mechanical parts that must therefore be serviced regularly to ensure long-term use.
Use a soft cloth or non-abrasive sponge to apply lukewarm water with a highly diluted, mild cleaning agent to the slats.
Carefully scrub away dirt. It is imperative that you then rinse the slats well with clear water.
Cleaning agents with alkaline, acidic or abrasive active ingredients and pressurized steam cleaning may not be used!
Interval Environmental conditions

Application note
The external venetian blinds cannot be protected with wind sensors against sudden gusts of wind. Make sure that the external vene-
tian blinds remain retracted if a storm is imminent. Updrafts or fallwinds at facades could lead to the destruction of the external vene-
tian blinds. Wind sensors cannot detect these as a rule.
