The Sleep Delay Function puts the unit in a standby mode after a user defined period
(1 - 6 hours). The Sleep Delay Function factory default setting is OFF. Pressing the
(UP) button increases the sleep delay time up to 6 hours. Press the (Accept) button
to confirm selection and the display reverts to the main menu. The unit will go into
"Sleep" mode if it has not been used during the "Sleep delay time" period. To exit
"Sleep", push any timer key or lever on the tap. If you activate the Sleep Delay Timer
we recommend that you also activate the Temp Show On/Off function.

Pressing the (UP) button scrolls from the filter OFF selection (this turns the filter
count off if a filter is not installed with the boiling water unit) up to 12,000 litres. We
recommend a default value of 4,000 litres, until the user knows the filter will last
longer. Press the (Accept) button to confirm selection and the display reverts to
the Filter menu.

The service menu has seven modes to select from (refer to 'timer functions' on page
