Follow these steps to install your ANNFUZ Mechanical Keypad Door Handle Lock. A Phillips screwdriver is the primary tool required.
Video 2: Step-by-step guide on how to install the ANNFUZ Mechanical Keypad Door Handle Lock.
6.1 Prepare the Door
- Ensure your door thickness is between 1-3/8" to 2" (35 mm-50 mm).
- Check the backset measurement (distance from door edge to center of bore hole). Use the appropriate 60mm or 70mm latch provided.
6.2 Install the Latch
- Insert the chosen latch (60mm or 70mm) into the door edge.
- Secure the latch with the two short screws provided.
6.3 Set Handle Orientation (Left or Right Handed)
The lock is reversible for both left and right-handed doors. Determine your door's handing:
- Viewed from outside, a door is right-handed if the hinges are on the right.
- Viewed from outside, a door is left-handed if the hinges are on the left.
Adjust the handle orientation on both the exterior and interior panels to match your door's handing. Use the spindle to rotate the arrow on the spindle hole to face 'L' for left-handed or 'R' for right-handed. Ensure the interior panel's handle orientation matches the exterior panel's handle.
6.4 Assemble the Lock
- Place the black rubber seal behind the exterior panel.
- Insert the spindle with spring through the latch mechanism.
- Align the exterior panel with the spindle and mounting bolts, then attach it to the door.
- On the interior side, align the interior panel with the spindle and mounting bolts. Secure the two screws on the interior panel, engaging the mounting bolts. Do not fully tighten yet.
- Before fully tightening, press button 'C' and test your passcode. Only if the handle turns and engages the latch correctly, then proceed to tighten the mounting bolts.
- Use the hex key to tighten the bolt on the handle of both the exterior and interior panels. Once tightened, the handle orientation cannot be changed freely.
