9.2 Preparation for installation
2.
Remove the old belt winder, if you are carrying out a
conversion to an existing roller shutter system.
◆ Let the roller shutter move fully down, until the slats
are completely closed.
◆ Remove the old belt winder and unreel the belt.
There is a risk of injury from the pre-tensioned
springs on the old belt winder.
◆ The spring unit can 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.
3.
Prepare the belt.
◆ Cut the belt off approx. 20 cm under the belt box.
◆ Fold the end of the belt over by approx. 2 cm and cut
a short slit in the centre. This enables you to subse-
quently 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.
