8.0 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.
8.1 The Supreme 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.
8.2 The amount of usage of the unit will also determine the quality 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 acess to the storage
tank).
8.3 The front cover and spout will require a periodic wipe to clean any
marks/splashes from use.
