Opening and closing window
Open window by turning handle to vertical position. The window will stay open in any position up to 45º.

Ventilation position
The handle allows the sash to be secured in a ventilation position.

Use of the ventilation flap
To enjoy fresh air even when the window is fully closed, pull the control bar lightly downwards to open the ventilation flap. The window will remain locked, but air can enter the room through a built-in air filter.

Cleaning the pane
Turn the handle to vertical position. pull the control bar downwards and rotate the sash 180 degrees. The sash must be secured in position by sliding the two barrel bolts into the bushings at the bottom of the side frames. This safety feature leaves both hands free for cleaning.

Clean the pane with a soft, clean, lint-free cloth/chamois leather/nonabrasive sponge or a clean, non-metal window squeegee. Clean water will normally be sufficient for cleaning the pane. Ordinary, non-abrasive household cleaners can also be used. Soft water is best for cleaning panes. Therefore, in hard-water areas add a small amount of detergent to soften the water or wipe off all excess water after cleaning.

Warning

• Avoid contact from silicone with the pane
• Do not use any cleaning products containing abrasive particles
• Do not use chemical products for cleaning the pane
• Avoid contact with the pane from all sharp or abrasive objects including jewellery
• Never attempt to clean off dirt on the pane without first applying water
• If any works are taking place in the vicinity of the pane, protect the pane with a clean plastic sheet to prevent any splashes or staining from aggressive and abrasive compounds

B. Adjusting springs (only if the sash cannot remain open in any position)
Position plate in the notch where the sash can remain open in any position (1, 2).
This depends on the roof pitc (3).
Test that the sash can remain open in any position.
