2-leaf window
VELFAC 201 Sidehung window
This window is opened by turning the handle to a horizontal position
and pushing the sash outwards. The window opens to 90º and is
equipped with a friction arm which allows the sash to be held in any
position between closed and fully open.
Double leafed windows can be supplied with different types of
mullion - see page 23 for more information.
Friction arm adjustment. The friction arm, found at the bottom edge
(or occasionally top), can be adjusted by turning the friction bolt using
a 4mm hexagon key.
Care.
It is important to keep the guide rails free of dust and dirt by
using a soft brush or cloth (2). The guide rails should not be oiled
as this will accumulate dust and dirt, and remove friction. The hinges
require oiling at least once a year using acid-free oil. In order to
ensure the hinges are properly lubricated, the window should be
opened and closed several times during and after oiling. (3).
