Screwing the transport units together
NOTICE
Material damage caused by mechanical pressure on components
Stress that occurs during transport may exert mechanical pressure on the components.
Material damage can result.
● Line the cabinets up precisely with each other in order to avoid shearing forces when the
base units are screwed together.
● Install the converter only on a level and horizontal surface.
Ensure that access to the holes in the bottom of the cabinets is unobstructed. Remove the
guard covers.
Mounting hardware
To screw the transport units together, you will need the following mounting hardware:
● Self-adhesive sealing strips
● Hexagon nut M8
