Classic All-In-One Tap:
The top levers and safety lock
button of the Classic AIO tap are
operated in the same way as a
Classic HydroTap to dispense
Boiling and Chilled water.
The Mixer tap lever is operated as a
classic ‘Flick Mixer’. The hot side is
marked with a red mark and the cold
side with a blue mark, for dispensing
cold to warm water.
Lifting the handle up will decrease
the flow rate and lowering the
handle will increase the flow rate.
Lift the handle all the way up to turn
the tap off.
When the handle is moved towards
the blue mark, the temperature is decreased and when moved towards
the red mark, the temperature is increased. The final temperature will be
dependant on the temperature of the incoming cold water.
For convenience, the spout may be swivelled, left or right through 120°.

Pump anti cavitation mode:
This feature sends two electric pulses every 5minutes to the pump. This
prevents the build up of air bubbles inside the pump and ensures an even
flow of hot water at the tap.
Power Pulsing mode:
This is a default set point control feature which ensures the hot water is
maintained as close as possible to the set point. This is achieved by applying
a closer tolerance to the set point temperature range. It is estimated that 1 in
15,000 installations could experience intermittent flickering lights, during the
boiling water recovery period. Disabling may overcome the flickering lights,
however, the unit may experience increased steaming.
Fan speed adjustment:
If the undersink unit is operating near 35°C then the fan speed must be
100%. The fan speed may be adjusted for quieter operation only if the
operating temperatures are considerably lower than 35°C.

water units are self calibrating to 98ºC, which is the recommended setting.
Adjustments to the 98ºC setting are not recommended however, under
certain circumstances adjustments may be made between 68º - 100ºC. It
should be noted that a 20% energy saving in standby power can be achieved
when the 98ºC setting is selected over the 100ºC setting. Furthermore,
the 100ºC setting is not recommended as the delivery rate of water will be
affected.
