1. Tarken installation

Open the window by turning the
window handle to the 90° position and pulling the handle towards you. Once the window is open, proceed to turn while slightly pulling the screw cover to make the screws accessible

Remove the window handle by
unscrewing both screws in a counter
clockwise direction. Keep the screws, since those will be needed later during the assembly of the Tarken device.

Use your thumb to open the front cover
by applying slight force on the button
while directing it outwards.
The front cover should open up after which it can
be easily removed by pulling it outwards.

Attach the Tarken device to the
window. The device has a square spindel
on the back side, which must be inserted
into the square hole in the window.
Make sure during the attachment, that the
screw holes on the Tarken device are
aligned with the screw holes on the
window. The back side of the device
should be touching the window panel.

Insert the same two screws that were
removed before into the screw tunnels
as shown. Proceed to screw
both screws in by screwing in a
clockwise direction. Do not use excessive force when tightening the screws.

Attach the front cover back to the
device by placing the hinges to their
corresponding slots and turning the
cover inwards until the cover locks.

NB! Use provided cleaning wipe to clean the window surface where the anchor is applied.

Remove the sticker cover foil from the wall anchor (Do not remove the sticker).

Keep the wall anchor aligned with the
Tarken device while slowly closing the window. Once the anchor touches the wall, apply pressure to make sure the sticker glue holds. Let the glue cure for 15 minutes before using the device.
