To install the GIANNI GS250 Series Mini Shear Lock, follow these steps:
1. Ensure that the door and frame are wide and deep enough to accommodate the shear lock. Make sure the central lines on the door frame and door leaf align. Install the magnet into the door frame before installing the armature assembly into the door leaf.
2. Before installation, ensure that the door always returns to the dead center after it is opened, especially with double-action doors. Use door hinges if necessary.
3. Tighten the set screws with the provided Allen wrench once the armature plate has been adjusted for the optimum door gap. This will securely fasten the armature plate and prevent it from becoming loose over time.
4. For mortise mount installation, make sure the gap between the door top rail and frame header is 2 mm. Mark the central lines on the door and frame where the magnet and armature assembly will be installed.
5. Attach the templates to the door and frame. Cut and drill holes where the templates indicate. Connect the wires. Install the shear lock and armature assembly towards the leading edge of the door.
6. Connect the power and check the unit.
7. For proper operation, ensure that the armature assembly is close and parallel to the shear lock without interfering with the opening and closing of the door. Maintain a distance of 2 mm between the armature assembly and the magnet.
8. If the magnet attracts the armature assembly when the door is not in position, adjust the door operator and floor hinges.
Please refer to the provided wiring diagram and the complete instruction manual for more detailed information and illustrations.
