Emergency release
- Pull the red lever in the motor (N) downwards once; so that the motor unlocks and the door can be opened manually (see figure 19).
- To install the manual release inside the door, fix it by means of the relative bracket inside the door handle, secure by means of a cable clamp (type.ZN24),
and position the cable in place of the red lever (W) of the motor release.
- If the area closed off by the garage door is not accessible from inside and the control needs to be released manually, an external release device must
be installed on the handle using the Elvox kit type ZN23.
INSTRUCTIONS FOR THE CURVED ARM
