^ If the furniture unit walls are 19 mm thick you will need to
drill four holes in the sides for securing the machine. To
mark the position of these holes:
– Align the machine in the niche. Screw the side socket
screws inside the machine in a little so that they make
indents in the side walls and then unscrew them again.
– Take the machine out of the niche and drill ø 4.5 mm holes,
2 mm deep where you made the indentations.
^ Connect the machine to the electricity supply.
^ Push it all the way into the niche until you feel resistance.
^ Open the machine door and partially tighten the side
socket screws.
^ Carefully turn the lower socket screws a to centre the
machine in the niche.
^ Tighten both upper socket screws b by hand to secure the
machine in the unit. Do not overtighten them.
