ing a dedicated junction box, the appliance must be
able to be isolated from the mains power supply by
an isolator that disconnects all poles with at least
3 mm contact separation.

ard plug or by a permanent connection.
The following electrical connections are permissible:
Connection to a freely accessible standard
socket with matching plug
Permanent connection to an appliance socket
with earth conductor

Cleaning

Almost every type of water will deposit limescale at high tem-
peratures. Limescale will settle inside the appliance and affect
its function and service life. The heating elements must there-
fore be descaled if necessary. A qualified contractor who is
aware of the local water quality will tell you when the next de-
scaling is due.
u A damp cloth is sufficient for cleaning the appliance. Never
use abrasive or corrosive cleaning agents.
u Check the tap regularly. You can remove limescale deposits
at the outlet using commercially available descaling agents.
