Chemical cleaning must be performed after initial start-
up, after a shutdown for more than four days, after a fil-
ter change or otherwise at least every 6 months.

Button for chilled water
3
Button for carbonated water (option)

LEDs blue and red
5
Dummy button
1
Service cartridge
WARNING
Risk of damage. The Hy-Protect filter will become dam-
aged if the Service Cartridge is used at the right-hand
filter position instead of the Active-Pure filter.
Always insert the service cartridge into the left filter
position instead of the Hy-protect filter.
CAUTION
Risk of injury from contact with detergent. Wear protec-
tive gloves and safety goggles when performing the
chemical cleaning.
Empty the can in units with drip pan drain.
Place a measuring cup with a capacity of at least 1
litre under the water outlet.
Press the button for unchilled water and the button
for carbonated water or dummy button at the same
time.
Note:
Simultaneous actuation of these two buttons starts the
cleaning programme. The dispensing of drinking water
is blocked during the cleaning programme. The clean-
ing programme with subsequent rinsing takes approx. 1
hour and must be carried out in its entirety. Due to safe-
ty considerations, the control does not permit the pro-
cess to be cancelled before completion.
When the acoustic signal sounds, hold the button
down for 5 seconds until the second acoustic signal
sounds.
All LEDs are flashing blue.
Push any button.
The pressure in the system is released. The pro-
cess takes 30 seconds.
All LEDs are flashing red.
Remove drip pan and open the device door.
As long as the door is opened and the drip pan is
removed acoustic signals will sound.

move it.
Put detergent into the service cartridge and insert
the service cartridge into the filter mount.
Dosage: 4 cleaning tabs.
Note
The following steps must be performed very care-
fully, as otherwise the effect of the chemical clean-
ing is not guaranteed.
In the event of malfunction during chemical cleaning
(power failure, device switch-off, message that the can
is full), the cleaning programme will always jump to the
rinsing process. The rinsing process must be carried out
in its entirety before the chemical cleaning can be re-
started.
Neither premature exiting of the cleaning programme
nor a shortened rinse cycle is possible.
Close device door and insert drip pan.
Place the measuring cup under the water outlet.
The LED of the button for unchilled water is flashing

Push the button for unchilled water and dispense
500 ml of water to fill the service cartridge.
5 seconds after releasing the button the dissolving
time of the cleaning tabs begins.
Wait for 2.5 minutes, while all LEDs are flashing
red.
As soon as the LED of the button for unchilled wa-
ter is flashing blue, actuate the button once again
until another 500 ml of water has flown into the
measuring cup.
Now the line for unchilled water will be flushed with
cleaning solution.
5 seconds after releasing the button the contact
time begins.
Empty the measuring cup during the 2.5-minute
contact time and place it under the water outlet.
As soon as the LED for chilled water is flashing
blue, push it until another 500 ml of water have
been dispensed.
The line for chilled water is flushed.
5 seconds after releasing the button the contact
time begins.
Empty the measuring cup during the 2.5-minute
contact time and place it under the water outlet.
As soon as the LED for carbonated water is flash-
ing blue, push it until another 500 ml of water have
been dispensed.
The line for carbonated water is flushed.
5 seconds after releasing the button the contact
time begins.
During the contact time of 15 minutes all LEDs are
flashing red and the buttons are deactivated.
Empty the measuring cup during the contact time
and place it under the water outlet.
After completion of the contact time all LEDs are
red.
Press the button for unchilled water and the button
for carbonated water or dummy button at the same
time.
When the acoustic signal sounds, hold the button
down for 5 seconds until the second acoustic signal
sounds.
The pressure in the system is released. The pro-
cess takes 30 seconds.
Remove drip pan and open the device door.
Remove service cartridge.
Insert the filter from the bottom into the relevant
support. Mind the position of the tab.
Turn the filter to the right all the way to the stop.
Check installation position.
The marking on the label on the support and on the
filter must be aligned with each other.
Close device door and insert drip pan.
Place the measuring cup under the water outlet.
The LED of the button for unchilled water is flashing
blue.
Start rinsing process (see "Rinsing after chemical
cleaning").
Note
The chemical cleaning process with rinsing takes ap-
prox. 1 hour.
The water dispensed during cleaning is not fit for
