Themaximum acceptable height difference between cabinet front and rear edges should be within +2/-0mm limit.The cabinet should always be fixed to the floor or to the wall. Depending on installation conditions,the cabinet sections can be fixed in different ways. There are holes in the front corners which canbe used for fixing. Additionally, the rails on the top of the cabinet have fixing lugs for fixing thecabinet to the wall.5.3.1 Fixing to the floor and to the wallIn installations where the cabinet is mounted against the wall, it is more convenient to fix the top ofthe cabinet to the wall. Fix the cabinet in the two front corners to the floor with bolts. Fix the top partto the wall with bolts.
