8.3 - Connection of the panel to the transmission belt
Install the belt by inserting it between the motor pulley and the
guide pulley. The two ends of the belt that will need to be joined
together must be on the lower branch.
To make the joint between the two ends, use the appropriate
brackets and proceed as shown in the figure below.
Once the two ends are joined, connect the junction plate to the
panel runner in the position indicated in the "Installation Dimensions
- top and front views" section according to the type of door being
