CAUTION!
There is a risk of injury from the pre-tensioned
springs on the old belt winder.
◆
The spring unit of the old belt winder may suddenly
recoil when it is removed.
◆
Hold the spring unit firmly when loosening the belt
and allow it to recoil slowly until the spring unit has
completely unwound.
8.2 Preparation for installation
2.
Remove the old belt winder, if you are carrying out a con-
version to an existing roller shutter system.
2.1
Let the roller shutter move fully down, until the slats are
completely closed.
2.2
Remove the old belt winder and unreel the belt.
3.
Prepare the belt.
3.1
Cut the belt off approx. 20 cm under the belt box.
3.2
Fold the end of the belt over by approx. 2 cm and cut a
short slit in the centre. This enables you to subsequently
hook the belt onto the reel.
Recommendation
The belt must run as straight and freely as possible. For
stiff roller shutters, mount a deflection roller on the belt
box. This helps to prevent unnecessary friction and wear
to the belt.
