7.0 MAINTENANCE
NOTE: Maintenance must be carried out by competent persons.
Competent - i.e. Trained, experienced, qualified.
Disconnect the electrical supply before removing the cover.
WARNING: Electronics control by switching ‘N’ (neutral), in some instances neutral
terminations will be at 230 volts with respect to earth.
7.1 The unit incorporates an electronic scale conditioning function which will
reduce the rate of scale deposition in hard water areas. However, some
deposits may still occur in the storage tank; these should be periodically
removed.
7.2 The amount of usage of the unit will also determine the quantity of scale
build up. A regular inspection of the tank every 6 to 12 months will provide
longer life of the product and optimum performance (removal of the steam
plate assembly will give access to the storage tank).
7.3 The front cover and spout will require a periodic wipe to clean any marks/
splashes from use.
