Warning and Safety instructions

If the mains connection cable is damaged, it must be replaced
with a special mains connection cable by a qualified electrician (see
"Electrical connection" in the "Installation" chapter).

During installation, maintenance and repair work, the downdraft
extractor must be completely disconnected from the mains
electricity supply. It is only completely isolated from the electricity
supply when:
- the mains fuse has been disconnected or
- the screw-out fuses have been fully unscrewed or
- the plug (if present) is removed from the socket. To do this, pull
the plug not the mains connection cable.
