Introduction
The operation of the Quooker COMBI+
The Quooker COMBI+ supplies boiling water and hot water. The tank is vacuum-insulated and
is connected to the cold water supply via an inlet combination valve. Inside the tank the water
is heated electrically to approx. 110°C and is kept at this temperature. When boiling water is
dispensed, cold water flows back into the tank at the same time and is heated automatically.
If the entire content of boiling water is used in one go, the heating time is ca. 20 min. Before the
water leaves the tank it is purified by the HiTAC
®
water filter (High Temperature Activated Carbon).
To extend the life of the filter, the water used for mixing the hot water is not filtered.
In addition to boiling water, the COMBI+ also supplies instant hot water. The Quooker COMBI+
supplies hot water by mixing boiling water from the Quooker tank with cold water from the water
mains inside the mixing valve. A thermostatic control element inside the valve keeps the outgoing
water temperature constant. This temperature can be set between 40°C and 60°C with the grey
knob on the mixing valve. The mixing valve is suitably protected against a loss in water pressure,
preventing any boiling water from flowing out of the mixer tap.
The grooved handle on the tap lights up when the water is running to warn the user that the
water is boiling. As an additional safety feature, the Nordic single tap is height-adjustable and the
Nordic single tap, the Fusion tap and the Flex tap are fully insulated.
Despite all the safety features incorporated in the product, anyone using the Quooker system
must keep in mind the risks of using boiling water in general. Incorrect use can lead to injury.
Therefore always read the manual carefully before use.
Installation, maintenance and warranty
The Quooker can be installed in almost any location provided there is sufficient space for the tank
as well as a 13 amp socket, water supply and waste pipe.
The Quooker tank must be fitted in an upright position. If the tank is to be fitted in a cabinet with
drawers, an optional bracket can be purchased to suspend the tank from the cabinet wall.
The HiTAC
®
filter inside the tank should be changed once every 3-5 years depending on your
water hardness. If you live in a hard water area, lime scale will collect at the bottom of the tank
and will need to be cleaned out by one of our engineers approximately once a year depending on
usage and the quality of the water in your area. Alternatively, you can install a suitable descaling
system. This system must not reduce the pH level of the water below 7 or remove all the minerals
from the water (reverse osmosis) as this can be harmful to the tank and would void the warranty.
Suitable descaling systems are also available directly from Quooker as an optional extra.
The warranty period is two years and covers parts and labour. It does not cover issues resulting
from insufficient lime scale maintenance.
