black fitting from the font using the supplied hose clip. Connect the black wire coming from the
water boiler to the wires coming from the font base (it doesn’t matter which wire goes to which
connector on the font)
Operating boiler for the first time:
Turn the water on at stop valve and switch the power on at the switch on the front of the machine.
1. Timer board works by default (after flashing) in "push & hold" mode.
2. To set a time dispense please follow the calibration procedure:
Open the service door on the front panel
Once the machine is full and heated up (the status LED glowing green) press the tactile switch
on the left control PCB (timer board).
Both pumps will turn on and off for 0.1s - that will be heard as a click meaning that the timer is
in the calibration mode.
Place an empty cup (measuring jug) underneath the fo nt that is to be calibrated.
Press and hold a font button until you get the right amount of water. The water does not have
to be dispensed in a single push - if the button is pressed few times the overall time will be
used.
Do the same action with the other font if needed. If only one font is calibrated, settings for the
other will not be altered.
The minimum time possible for the time dispense operation is 1s. Setting the dispense time for
less (quick font button click) will set the font back into "push & hold" mode.
After the volumes are set properly press the tactile button on the timer board once again.
Both pumps will turn on and off for 0.1s twice - that will be heard as a double click meaning
that the timer is out of calibration.
3. Please note that there is no given order which font is to be calibrated first - in fact they
may be calibrated at once or only one may be calibrated (leaving the settings of the other
unaltered).
4. If there is no response from the user in the calibration mode (none of the font buttons
pressed) for more than 25 seconds the timer will end the calibration (double pump "click"
will be heard).
5. The maximum allowable time of the dispense is 25 seconds. Any longer times will be cut
down to 25 seconds.
6. The resolution of the time measure ment is 0.1s.
7. The timer board has its own clock on board therefore power line frequency is not used to
measure the time.
Troubleshooting:
The Ready/Status light signals various errors or problems. A cycle of red flashes indicates an
error.
