2.2 Step-by-Step Installation
Follow these steps to install your Hugolog electronic deadbolt lock:
- Install the Latch: Ensure the latch is oriented correctly (facing upwards) and install it into the door frame. Secure it with two screws. Test the deadbolt's smooth operation with a screwdriver and keep the latch in the retracted (unlocked) position.
- Install Exterior Assembly: Hold the exterior assembly flush against the door. Guide the key tailpiece and power cable through the door hole.
- Install Mounting Plate: Install the mounting plate, ensuring it is parallel to the door edge. Secure it with the provided screws.
- Connect Interior Assembly: Connect the power cable from the exterior assembly to the socket on the interior PCB. Rotate the thumb turn to a vertical, upward-facing position.
- Fix Interior Assembly: Fix the interior assembly to the mounting plate. Test if the latch works smoothly by rotating the thumb turn.
- Insert Batteries and Reset: With the lock in the unlocked state, insert three new AA alkaline batteries into the battery pack. Use the reset tool to press and hold the reset hole for 3 seconds until you hear a beep. The deadbolt will then reallocate to learn the door's orientation.
- Complete Installation: Put back the lid of the battery pack. Test the lock's functionality using the backup key and the default master pin code (12345678).
