water is added manually by the operator.
ECO Mode Operation:
Note In the COOL FILL mode [see Service setup setting 5] the ECO Mode is

 All ECO Boilers use high grade insulation and it is applied to give a significant energy usage
improvement over a standard water boiler.
 The under counter range incorporates a ½ tank 'ECO mode' function.
 To enable the 'ECO Mode' press the button located below the 'Ready' indicator so that the leaf
symbol illuminates green.
 This mode saves energy by minimising the energy wasted during machine down-time.
 NOTE: The ECO mode is most effective in installations where the machine has a regular 'off'
period.
 To achieve the most benefit from the energy saving 'ECO Mode' on your ECO boiler unit (10L
variants only), the following method should be employed:
o Towards the end of the boilers operating period for a given day, switch the machine to
ECO Mode. Whilst maintaining water at 96
full, where it will remain.
o At the end of the machines operating period it should the be turned 'off'.
o During the 'off' period as there is less water in the tank there will be less energy lost to
the surrounding environment resulting in an energy saving.
 To disable simply press the 'ECO Mode' button again so that the leaf symbol is not illuminated
