Activating Calibration Reset Mode: - 703 Series
Different altitudes will cause water to boil at different temperatures. To prevent the
water in the boiling water tank from boiling continuously (which is energy inefficient)
the boiling water unit is fitted with an altitude calibration function which automatically
operates when the unit is operated for the first time or if „calibration reset mode‟ is
activated. If the boiling water delivery temperature is not hot enough or the unit
continuously boils, ‟calibration reset mode‟ should be used to recalibrate the unit.
When the unit is calibrating, the BWU will boil the water twice (approximately 60
seconds each time) in order to calibrate the optimum boiling point according to
altitude. During this procedure steam and water droplets will be vented from the vent
outlet on the tap. The entire calibration period will take approximately
minutes and must not be interrupted; this includes operation of the tap outlet.
To activate calibration reset mode, turn off the power to the unit. Press and hold the
„Eco‟ button and restore the power to the unit. Once the heating LED is flashing,
release the „Eco‟ button. When the unit has completed its calibration cycle, the red
heating LED will illuminate solidly.
