Place the opener in the centre of a window vent and mark the position of the holes on the window frame and greenhouse frame.

Screw the automatic window opener to the frame of the window then check that the window can open and close.

If necessary, adjust the amount the window opens by rotating the main tube of the vent opener.

On a sunny day, watch and wait to see that the vent is opening properly.

UPVC greenhouses have lightweight roof vents and may require a stronger vent opener to keep them closed or prevent them being blown away.
