The WLH2 Firewall incorporates volumetric dispensing control. This allows a specific auto-
dispensed volume of water to be preset for any of the 4 dispense buttons. The below steps
explain how to program dispense of both cold and sparkling options. IMPORTANT: Water must
be dispensed to calibrate the preset, so have a container ready in the dispense area to catch
this dispensed water.
• Pre-set Sparkling or Still water volume: Press both dispense buttons simultaneously
of either the sparkling or still buttons together for 5 seconds.
• Once programming mode is initiated, both sparkling button LED backlights will be
flashing.
• With a container in the dispense ready to contain the water dispensed, give a short
press and release of the dispense button you wish to preset. Water will begin to be
dispensed.
• Once the desired amount of water has been dispensed, give the same button
another short press and release to end dispensing.
• That button has now been preset to that specific volume of water.
• The two buttons for sparkling should still be flashing. At this time, the other button
can now be preset for a different volume of water if desired using the same method,
or the programming mode can be exited.
• To exit the setting mode, press both dispense buttons simultaneously for either
sparkling or still water again for 5 seconds and the LEDs will return to solid light.
(Maximum dispensing is 3liters.)
NOTE: Factory presets for the small and large dispense buttons are 750ml and 1000ml
respectively.
