8.1 The electronic control system of the Supreme has a self-
diagnostic feature which determines if the unit is operating
satisfactorily. It will automatically calibrate for water quality and
temperature.
8.2 If steam or boiling water discharges from the vent pipe the
Supreme will switch off. A critical fault would render the unit
unsafe to use and so will deactivate both the element and
solenoid valve.
8.3 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.
Heatrae Sadia are pleased to offer a preventative maintenance
program to ensure that your product will continue to operate to your
satisfaction in even the most troublesome of water conditions.
The service provided includes an inspection, descale and functional
test, scheduled to meet your requirements. All work under the plan
will be carried out by one of our authorised service engineers, who are
fully trained, regularly audited and carry a complete stock of spare
parts. This plan is in addition to the manufacturer's warranty and does
not cover the cost of materials associated with any out of warranty
component repairs.
