Corner Unit Installation
Remove all doors and shelves and set in place. Level up to your base unit line marked on the wall and ensure the top, sides and front area all level using the feet to adjust. DO NOT FIX BACK CABINET YET!!
Fit the next two units that sit either side of the corner unit and level up to suit the corner unit. Remove doors, drawers and shelves.
Ensure the front of the carcass and the top of the carcass are flush, attach one or two clamps to the units to hold them to the corner unit Affix these together by drilling a pilot hole. Be careful not to drill through the hole. Finish by screwing together. [See below picture showing drilling pattern and information.]
Remove clamps and double check units are still level and square to the wall. Also double check remaining space is still accurate for the remaining cabinets.
Consult your recorded stud locations and use 2-4 screws per unit or 4-8 for a corner unit to fix each unit back to the wall. Use small packers in the back where necessary if there are gaps to avoid twisting the cabinets out of square.
Check the level throughout this process and tighten or loosen screws to ensure they stay level and square.
