OPER ATION:
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 “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 96ºC 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.
Whilst the machine is above the safe level and 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.
The boiler is now ready for use.
