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
ltered 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 ltered water is being dispensed and ashes blue when
sparkling water is used. To ensure the water quality, the Quooker CUBE has two in-built lters,
a hollow bre and a carbon lter, that clean the water before it is dispensed. The Quooker CUBE
is equipped with a Quooker CO₂cylinder, 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 rells with cold mains water. Please note: If no sparkling or ltered water is
dispensed for approximately 14 days, we recommend you ush both sparkling and ltered water
through for two minutes each. This will rell the CUBE’s tank with fresh water and ensures an
optimum water quality. The temperature of sparkling and ltered water cannot be adjusted.
The amount of CO₂ in the sparkling water can also not be adjusted. Only CO₂cylinders from
Quooker can be used, as these were developed specically 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 ltered water. The ltered water feed passes through the chilled
sparkling water which in turn reduces the temperature of the ltered water by around 5 degrees as
it is dispensed. The temperature of the ltered 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 CO₂pressure 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 lters inside the CUBE must be replaced annually.
After 12 months, the CUBE will start beeping and the light on the CUBE tank will ash to indicate
that the lters need to be replaced.

Do not connect the CUBE if it is damaged. This may result in hazardous situations or harm
the environment. When discarding the equipment, the compressor and the refrigerant in the
compressor system must be discarded correctly, in an environmentally friendly manner. Used lters
should be disposed of in the general waste.
The warranty period for the CUBE and Quooker system is two years and covers supply of parts
only. It does not cover labour costs or any mechanical failure due to limescale. Only genuine
Quooker parts should be used with a Quooker and use of any third party parts of any sort will void
the warranty.
Users
The Quooker tap may be used by children over the age of eight and people with reduced physical,
sensory or intellectual capacity if they are supervised or have been told how to use the device
safely. People who are not yet familiar with the Quooker system must be told how to use it safely
and informed of the potential hazards associated with the use of the boiling-water tap.
Please note: Improper use may cause injury. Prevent children from playing with the tap, and do not
let children clean or maintain the product without supervision. Keep the plug and the cable out of
the reach of small children. The Quooker system is suitable for domestic purposes and use.
If connectors are defective, they must only be replaced by a qualied technician. ‘Tips for use’ and
an installation guide for the CUBE can also be found at www.quooker.co.uk

Installing the CUBE
We recommend installing the CUBE in the following order:
A. Connect the water supply
B. Connect the CUBE to the Quooker tank
C. Install the CO₂cylinder
D. Prepare the CUBE for use
The illustration below shows an example of a CUBE installation with a Quooker Flex tap and
a PRO3 tank, and is for illustration purposes only. The CUBE installation is the same for all
compatible Quooker tanks and taps. All installation guides are available online at
www.quooker.co.uk

Installation requirements
Please read the following before you start the installation.
Placing the CUBE
Make sure that the CUBE tank has enough room within the kitchen cabinet. Please bear in mind
that the CUBE must remain accessible for future service and maintenance. We recommend leaving
at least 10 cm of free space behind the CUBE tank for ventilation. The CUBE must be placed within
90 cm of the Quooker tank.
Ventilation in the kitchen cupboard
The kitchen cabinet in which the CUBE is installed must be suciently ventilated to ensure optimal
operation. We therefore recommend cutting an opening measuring 20 × 20 cm (400 cm²) in the
rear panel of the cabinet or equivalent. If there is not enough free space for ventilation behind the
rear panel, we also recommend making an opening in the bottom of the cabinet, under the CUBE,
for further ventilation.
Extra socket
The CUBE installation requires an earthed power socket. If there is no spare socket available, you
have the option of purchasing a Quooker Powerswitch. The CUBE’s maximum power consumption
is 100 W. Only use the power cable provided. If the power cable is damaged, it must be replaced
with an identical one. If necessary, contact Quooker for a replacement cable.

Connect the CUBE to the Quooker tank
• Please note: Make sure that the hose between the Quooker tank and tap has cooled down
before removing it.
• There are two jack plug ports at the back of the Quooker tank cover which will be used to
connect the Quooker tap and the CUBE. One of the ports is covered by a plastic cap that must
rst be removed.
• The CUBE and the tap are connected on top of the tank using a mini jack connector.

1 Connect the CO₂pressure reducing
valve
Push the clear CO₂ hose provided into the
push t connection on the CO₂ pressure
reducing valve.
2 Connect the CUBE unit
Remove the protective cap from the push
t CO₂ connection at the rear of the CUBE
and push the CO₂ hose into the coupling.
3 Connection to the CO₂cylinder
Hold the CO₂ pressure reducing valve
vertically. Remove the protective cap
and screw the cylinder into the CO₂
pressure reducing valve until it cannot be
tightened any further. It is important that
it is thoroughly tightened so that a tight
seal is formed. Some gas may escape
and a hissing noise may be heard. This is
perfectly normal, but it is important that you
ensure the cylinder is tightly screwed in.
4 Positioning of the CO₂cylinder
Once the CO₂ cylinder has been screwed
rmly into the CO₂ pressure reducing
valve, attach it onto the top edge of the
CUBE. The cylinder can be hung on the
front or on either side of the CUBE.

Prepare the CUBE for use
• Depending on the temperature of the cold mains water supply, it takes about 40 minutes for
the water in the CUBE’s tank to cool down completely. The rst time after installation of the
CUBE, it will take about 60 minutes.
1 Switch on the water
Switch on the mains water supply. Open
the CUBE stop valve by turning the blue
handle. Check for leaks.
2 Connect the power supply
Make sure that the ‘COLD’ switch on the
rear of the CUBE is set to ‘0’. Connect
the power cable provided to the CUBE.
Connect both the CUBE and the Quooker
tank to mains power sockets and switch
on the sockets. Switch on the Quooker
tank by pressing the ‘Q’ button on the top
of the tank.
3 Flush the CUBE – ltered water
Flush the CUBE’s ltered water through
twice for one minute each time (the
tap switches o automatically after one
minute). To dispense ltered water, hold
the textured ring down until the tap lights
up blue, then turn it anti-clockwise. Initially,
black water will ow out. This is from the
built-in carbon lter and is completely
harmless.
4. Switch on the CUBE
Set the ‘COLD’ switch on the rear of the
CUBE to ‘1’. The CUBE will now start to cool
the water and the pump will be activated.

55 Venting the sparkling water
Dispense sparkling water by pressing the
textured ring down and turning it anti-
clockwise in one movement. The LED ring
starts ashing blue and CO₂is released.
Initially only air and CO₂will be released
from the tap. Keep the tap open for ca 10
seconds. The pump will be activated and
CUBE will ll with sparkling water. This can
take up to 3 minutes. The pump may be
very audible during this process.
6 Flush the CUBE – sparkling water
Dispense sparkling water twice, for
approximately one minute each time, to
ush the system through before rst use.

back of the CUBE is set to ‘0’. Do not
remove the power cable.
2 Empty the CUBE
Drain all sparkling water from the tap
and turn it o when only CO₂ gas comes
out. You may need to dispense sparkling
water twice before the CUBE is completely
drained.
3 Shut o the water
Shut o the water supply to the CUBE
using the blue stop valve. Check that
the system has been depressurised by
dispensing ltered water from the tap. No
water should come out. Unscrew the CO₂
cylinder from the CO₂ pressure reducing
valve. A small quantity of CO₂ gas may
escape.
4 Remove the CUBE
Remove the blue connector from the blue
port at the back of the CUBE and remove
the plug from the power socket. Remove
the hoses by pressing down on the grey
ring on the push t connections whilst
