Click vent.
The click vent is fitted
within the frame and provides
background ventilation. The vent
is opened by pressing one or both
ends marked with circles.
The
PN-fitting
makes it difficult
for unwanted guests to enter if the
window is open. When opening the
window, the arm is lifted and re-
engaged when the required opening is
achieved. The arm is raised to a verti-
cal position to disengage, allowing the
sash to open fully.
N.B:
Please note that some insu-
rance companies will not cover los-
ses from burglaries which have been
commited when windows have been
left in a ventilation position.
Window stay.
The arm is fitted to
the wood frame and when used, is
hooked into an eyelet on the sash to
achieve an opening of approximately
130mm.
The safety restrictor
automatical-
ly engages when the sash is opened
to approximately 4cm. To open further,
the sash is pulled slightly back while
disengaging the restrictor.
The lockable restrictor
limits the
opening of the sash to 1.5-10cm. It
is possible to disengage the restric-
tor by turning the lock through 90
°
with a 5mm hexagon key. Now the
restrictor arm may be pushed out of
the gliding rail. The lock must always
be re-engaged after use. The gliding
rails should frequently be cleaned
from dirt.
The friction arm
will retain the
open window in any ventilation posi-
tion under normal weather condi-
tions. If it is really windy the ventila-
tion position in the handle is to be
used instead (see p. 20). The friction
arms are adjusted by the factory
to fit the size of the window. If the
window opens too tight or too loose,
the friction arm may be adjusted
(see more by the relevant type of
window).
