Dear customer, here you will find a guide on how to wall mount your bookcase.
Place the wall bracket horizontally on the wall, please use a "spirit level". Place the lower left corner of the wall mount 11 cm lower and 3 cm to the right from the desired highest left corner of your bookcase. Please refer to the illustration. This way you can easily measure where to place the wall hanger before hanging your bookshelves on the wall.
 
Start by turning the adjustable metal washer at each end of the wall plug (use a flat screwdriver) so that the +/- indicator faces 12 o'clock. Place the wall mount horizontally on the wall. Mark for drilling in the two adjustable holes. Drill and insert screws in the two holes. Place the wall mount on the two screws and make sure it is level. If it is not leveled satisfactorily, adjust the level by turning the adjustable metal washer. Once you have adjusted one or maybe both sides of the wall mount - make additional holes in the wall to match the pre-drilled holes in the center of the wall mount - this way you have an extra strong and stable wall Installation
In your packaging you will find two adjustment devices. These adjusters allow you to level your Bookcase vertically if your wall is slightly uneven. Use them by removing the tape and placing them in each of the bottom corners of the back of your bookcase. Turn the metal washers anti-clockwise to align between the wall and the bookcase
