TRANSMISSION RAIL FASTENING
- Fasten the transmission rail in the following manner:
a) for sectional doors C-type (see ref. p.4), fasten the bracket directly over the spring-release coiling shaft using adequate dowels
and screws; if the distance between the coiling shaft and the gate’s upper ledge is between 30 and 60 cm, apply the V122 arm (read
the technical documentation provided with the accessory);
b) for A-B-type overhead doors (see ref. p.4), verify the maximum door sliding point (g.2) and consequently fasten the bracket on
high with adequate screws or rivets.
N.B.: for counterweighted overhead doors, partial entry, it is necessary to use the adapter arm V201 (read the technical
documentation provided with the accessory).
- Raise and set the guide horizontally to establish the distance from the ceiling; then fasten the angle sections or fastening brackets
provided (cutting off any excess part) to the rail’s back terminal. N.B. the transmission guide has three ø7 holes for further fastening
should it prove necessary to reinforce the unit.
- Lift, level and x the rail to the ceiling.
- Prepare the chase for electric wiring.
