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 rmly when loosening the belt

and allow it to recoil slowly until the spring unit has

completely unwound.

11.2 Preparation for installation

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.

Prepare the belt.

◆ Cut the belt o 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 sti roller shutters, mount a deection roller on

the belt box. This helps to prevent unnecessary friction

and wear to the belt.
