Electrical connection
Important
The electrical safety of this appliance
can only be guaranteed when
continuity is complete between the
appliance and an effective earthing
system, which complies with local and
national regulations. It is most important
that this basic safety requirement is
present and tested regularly and if
there is any doubt the electrical wiring
in the home should be inspected by a
qualified electrician. The manufacturer
cannot be held liable for the
consequences of an inadequate
earthing system such as an electric
shock.
The manufacturer cannot be held
liable for damage which is the direct
or indirect result of incorrect
installation or connection.
