Mounting

Preparatory steps
● Remove the crane transport assembly (if fitted)
● Observe the "five safety rules".
Mounting
The letters and numbers in parentheses in the installation steps refer to the diagram below.
NOTICE
If cabinet units are installed in a side-by-side configuration, the canopies must be flush-
mounted (c) in a line across the cabinet units (d) (see diagram). Once mounted on the
Cabinet Module, the spacers must lie vertically at 90° to the canopy.
In order to prevent water from penetrating into the spaces between the cabinet units, the
canopies are equipped with "gutters" that interlock in the side-by-side configuration.
