4. Setup and Installation

The DEVO G8 Smart Lock is designed for easy installation on most standard US doors without additional drilling. Follow these steps carefully:

4.1. Check Dimensions and Install the Latch

1. Use the provided measuring cardboard to check your door's dimensions. Verify the door hole diameter (25mm), cross bore diameter (38mm/54mm), and backset (60mm/70mm).

3. Insert the deadbolt latch into the door edge hole. Ensure the 'UP' marking on the latch is facing upwards. The latch must be in the retracted (unlocked) position when installed.
4. Secure the latch with the provided screws.

4.2. Install the Exterior Assembly

1. If your door's cross bore is 38mm, remove the adapter from the exterior assembly. If 54mm, keep the adapter.

4.3. Install the Mounting Plate

1. Pass the wires from the exterior assembly through the mounting plate.
2. Place the mounting plate against the door, ensuring it is correctly positioned with no gaps between the plate and the door panel.
3. Select the correct screws (Screw A for door thickness 45-55mm, Screw B for door thickness 35-45mm) to install the mounting plate.

4.4. Install the Interior Assembly

1. Adjust the rear lock knob on the interior assembly to the vertical position.
2. Connect the cable from the exterior assembly to the interior assembly.
3. Tuck the remaining cable into the back of the interior assembly.
