 Secure the retaining brackets to the
rear wall using the screws supplied.
The housing must be secured firmly
to the rear wall of the furniture unit.
If this is not ensured, the housing
may lean forwards and the canopy
could be damaged when it is pulled
out and pushed back in.
If the furniture unit does not have a
non-yielding rear wall, the retaining
brackets must be attached to the
kitchen wall. To do this, suitable
means of attachment must be used.
