Cleaning of water tank and covers –
weekly (15 – 25)
Clean the water tank, top cover, fragrance
container and steam pipe with a soft plastic
brush and dish detergent and rinse well (17).
Decalcification-Mode
Only use CalcOff for decalcification. Damage that is caused
by the use of other cleaning agents is not covered by the
warranty.
The Decalcification-Mode enables simple cleaning and
decalcification of the steam tray, water base, and steam
pipe.
The Anti-Mineral-Pad needs to be removed, before starting
the Decalcification-Mode (18) (see section about Anti-
Mineral-Pad). Dissolve the CalcOff decalcification agent in
1 L of hot water and pour into the water base (19). Then
reinsert the steam pipe and top cover (20). Pressing and
holding button A for 5 seconds switches the appliance to
Decalcification-Mode (21). Decalcification-Mode is shown
on the display by the flashing symbol E (22). The value «4h»
is shown flashing on the display. Button C can be used to
change the decalcification period from 1h to 9h, depending
on the level of soiling (22). After 3 seconds without further
input, the set value is taken as «desired value» and the flash-
ing display changes back to «CURRENT». The unit heats up
the CalcOff-water solution during Decalcification-Mode and
shuts off after it is finished. The heating of the water takes
place every 30 minutes while the Decalcification-Mode is
active. The cleaning period is now permanently displayed
and switches to minutes when the time falls below the 1
hour mark. The cleaning period can be changed at any time
by pressing button C. At the end of the cleaning period, a
short double signal is sounded, the display shows the value
«0h» and the cleaning symbol E will rapidly flash (23). Press-
ing button A ends the Decalcification-Mode and switches
off the appliance (23).
CAUTION: The water base must now be emptied of the
CalcOff and rinsed (24 – 25). Make sure no water enters
through the ventilation opening (25). Tip: In case of very
tough lime, decalcify overnight (12 to 15 hours).
Cleaning the housing – once or twice
annually (26).
Clean the housing with a damp cleaning rag and wipe it
dry; use a cleaning agent suitable for plastic if needed.
After usage
• Switch the appliance off by pressing button A (27).
• Disconnect power plug (15).
• Wait until the appliance has completely cooled off.
• Empty any remaining water and clean the water tank
and the water base. Decalcify if necessary.
• Let the appliance dry.
