5. The thermostat can be used to heat the water to
any temperature between 30°C and 97°C.
The ideal water temperature when making coffee
is approx. 97°C.
6. The water boiler is now ready for use.
• When drawing off hot water, the orange filling
switch must be turned off, so that cold water can
no longer flow into the boiler.
• The quantity of water to be added to and/or
drawn off can be checked using the volume
scale next to the gauge glass.
• In the event of breakage or repair work, the
gauge glass can be shut off by closing the gauge
glass tap (fig. 1J).
• The water temperature is easy to read from
the thermometer.
• When drawing off water using the swivel-arm
tap, open the tap as far as possible, allowing it to
vent properly. Afterwards, the flow can be
reduced to a level that can be processed by the
water distributor on the filter.
• After use, both switches must be turned off,
shutting off the water supply and electricity. It is
possible to keep water at a temperature of
at least 60°C overnight, but it is important to
make sure that the orange filling switch has been
turned off.

Fig. 7
Basic rules for brewing coffee
• Use regular ground coffee (± 50 gram/litre).
• Keep the containers and the filters clean.
1. The inner pot of the container must always be
fresh and clean.
2. To avoid temperature loss during the brewing
process we recommed you to pre heat the
container, by putting the cable into a power
socket. Fil the container with approx. 2 litres of
hot water and switch on the container for at least
10 minutes before the brew starts. The indication
lamp on the container will light up.
3. Tap the water from the container and place the
blender into the container.
4. Place a basket filter paper into the filter with the
appropriate amount of coffee (normal/medium
ground). The coffee must be evenly spread over
the filter. Generally speaking you will need about
45-50 grams per litre.
5. Place the filter lid on the filter, put the filter on the
container and position the swivel arm over the
centre of the filter lid.
6. Fill the water boiler with the required quantity of
water (fig. 1H), switch on the heating system
(fig. 1G) and wait until the water has reached the
temperature set. Open the tap as far as possible,
enabling it to vent properly. Afterwards, the flow
can be reduced to a normal level. Adjust the flow
so that the water does not run over the
distributor tray in the filter lid. Doing this will
ensure that the right filtering speed has been set.
7. The brewing process is starting, the blender in
the container guarantees a uniform quality of the
coffee, which makes stirring the coffee (with loss
of time, temperature and aroma) unnecessary.
The temperature of the coffee is kept at a
temperature of 80 - 85°C.
The storage time of the coffee is determined by
the blend of coffee and is usually 1 - 1,5 hours.
8. Once the water level in the water boiler has
reached 0, the tap can be closed and the water
boiler can be refilled and heated for the next
brew.
9. After the coffee has been made and the filter
has leaked out, the latter can be removed and
the lid can be placed on the container.
10. Rinse the filter after use.
Attention! Always place the blender / transport disk
and the lid when transporting the container (by hand
or serving trolley), this prevents spilling from the
container.

7.2 Descaling
During operation scale will form in the machine.
Therefore the machine needs to be descaled
regularly to guarantee the lowest energy
consumption and proper functioning.
When to descale?
Depending on the use and hardness of the water, we
advise you to have the WKI descaled by a service
technician every 5 or 6 months.
Depending on the frequency of usage and the
hardness of the water, we advise you to inspect the
appliance regularly for scale formation.
Remove the cover of the water boiler regularly;
If there is loose scale grit on the bottom, or if there
is severe scale formation on the walls, then the unit
needs to be descaled.
Descaling procedure for the service engineer:
1. Switch off the appliance and remove the plug
from the socket.
2. Remove the bottom plate by unscrewing the
fastening bolt in the middle of the plate.
3. Once the hexagonal plug has been removed
from the red drain tap, the drain tap can be used
to completely drain the water boiler.
Any loose boiler scale will then be removed.
4. Close the red drain tap, replace the hexagonal
plug and bottom plate (for safety reasons).
5. Switch the water boiler on again, allow it to
fill until all scale deposit has been completely
submerged.
6. Switch on the heating system and heat the water
to a temperature of approx. 60°C.
7. Read the warnings and other instructions
indicated on the Animo scale remover.
WARNING
• To descale the WKI the appliance needs to be
opened and partly disassembled. As a result
components are opened up that have a high
voltage and are not covered. Always discon nect
before opening the appliance!
WARNING
• Since the drain tap is located in the electrical
part of the water boiler, users are advised (for
safety reasons) not to descale the hot water
boiler themselves!
8. Add the scale remover to the heated water.
Please note:
once the scale remover has been added, the
water will start to foam. In extreme cases, where
too much scale remover has been used, the
foam may flow over the edge of the water boiler!
9. When no more scale remover is required
(no foaming occurs when more scale remover is
added), drain the water boiler via the tap.
In the event of obstinate boiler scale, repeat
steps 5-9.
10. Repeat steps 1-4 in order to drain the water
boiler.
11. Once all boiler scale has been removed, rinse
the water boiler thoroughly with clean water, not
forgetting to also rinse the tap.
12. The water boiler is now ready for use again.
8. Dry-boil protection
This appliance is equipped with a dry-boil protection.
This protection triggers if the heating element
overheats owing to a fault. Once the fault has been
resolved, the dry-boil protection can be reset at the
left side of the appliance (fig 1I). The most common
cause of the dry-boil protection being triggered is not
descaling the heating system in time.
If the heating system does not switch back on,
proceed as follows:
1. Allow the appliance to cool down.
2. Unscrew the protective cap.
3. Press the button which is now visible and firmly
screw the protective cap back on.
If the dry-boil protection triggers owing to increased
scale deposits, descale the appliance.
See chapter 7.2. Consult your dealer if the fault was
caused by a problem other than the dry-boil
protection being triggered.
