Operating boiler for the first time:
 Check that all installation procedures have been carried out.
 Ensure water valve is on.
 Plug boiler into 13A socket and press power button on the front of the machine marked 'Power'.
Refer to Figure 1.
 The "power on" light will glow green and the machine will fill to a safe level, above the elements,
before heating. The display will show the current water temperature and the status " Filling..."
 The "Ready/Status" light will cycle two red flashes while the machine is filling to the safe level.
 After this amount of water has heated to about 92ºC the boiler will draw more water in until the
temperature drops by 1 or 2 degrees. The boiler will then heat again. This heat fill cycle
continues until the boiler is full.
 While filling, the "Ready/Status" light will remain blank.
 The "Ready/Status" light will glow green when the machine is both full and up to normal operating
temperature. For 10L machines allow approx 30 minutes.
 The boiler is now ready for use – the display will show the Water Temperature and the status "
READY".
 The Boiler may now be used to dispense Hot Water to the preset factory settings.
