Introduction
How the Quooker CUBE works
This guide assumes that a Quooker tank complete with Quooker tap has already been installed.
For installation of the Quooker tank and tap, please refer to the installation guide which was
provided with the Quooker tank.
With the Quooker CUBE, you not only get hot, cold and boiling water, but also chilled sparkling and
filtered water, all from your Quooker tap. The Quooker CUBE can only be connected to Quooker
tanks and taps with a W in their serial numbers (e.g. QW106214/VCW302448).
The LED ring on the tap lights up red when boiling water is being dispensed or when the tank
is heating. The ring lights up blue when filtered water is being dispensed and flashes blue when
sparkling water is used. To ensure the water quality, the Quooker CUBE has two in-built filters,
a hollow fibre and a carbon filter, that clean the water before it is dispensed. The Quooker CUBE
is equipped with a Quooker CO₂ cylinder, that supplies approximately 60 litres of sparkling water.
The CUBE’s tank holds two litres of chilled sparkling water. When sparkling water is dispensed,
the CUBE immediately refills with cold mains water. Please note: If no sparkling or filtered water is
dispensed for approximately 14 days, we recommend you flush both sparkling and filtered water
through for two minutes each. This will refill the CUBE’s tank with fresh water and ensures an
optimum water quality. The temperature of sparkling and filtered water cannot be adjusted.
The amount of CO₂ in the sparkling water can also not be adjusted. Only CO₂ cylinders from
Quooker can be used, as these were developed specifically for the Quooker CUBE. This is to
ensure the quality of sparkling water dispensed and the safety of the product. The CUBE can
dispense an unlimited amount of filtered water. The filtered water feed passes through the chilled
sparkling water which in turn reduces the temperature of the filtered water by around 5 degrees as
it is dispensed. The temperature of the filtered chilled water will therefore vary depending on the
incoming water temperature and the amount of chilled sparkling water inside the CUBE tank. When
emptied completely, it takes around 40 minutes for the 2 litres of sparkling water to fully cool down
again.
Installation, maintenance and warranty
This guide assumes that a Quooker tank complete with Quooker tap has already been installed.
To install the Quooker CUBE, a mains water connection and a spare power socket is needed.
If no spare socket is available, a Quooker Powerswitch can be used. You can purchase the
Powerswitch directly from Quooker.
The CUBE is supplied with a connection pack, including the CO₂ pressure reducing valve and
a CO₂ cylinder. It’s not permitted to connect the CUBE to a reverse osmosis system or water-
softener which lowers the pH level of the water. Clean the CUBE’s ventilator fan once a year using
a brush or vacuum cleaner. In addition, the filters inside the CUBE must be replaced annually.
After 12 months, the CUBE will start beeping and the light on the CUBE tank will flash to indicate
that the filters need to be replaced.
