Cleaning
Prior to any maintenance, cleaning and after each use, turn off the unit and
remove the plug from the plug socket. Before you clean Karl / Karl big, the
power adapter (1) must be separated from the power adapter connection (2).
Attention: Never submerge the appliance in water (danger of short-circuit).
For hygienic reasons and to ensure proper operation, we recommend the fol-
lowing cleaning intervals.
• Daily: Fill the appliance with fresh, cold tap water. If the appliance is not
used for several days, empty the water from the lower part (4) beforehand
and if necessary, clean it with a bit of dish detergent and a clean cloth. Fill
fresh water into the lower part (4) before putting the appliance back into
operation.
• Every 2 weeks: First remove the filters (15) and the Water Cube™ (18).
Clean the inside of the lower part (4) thoroughly every 2 weeks with a bit of
dish detergent, warm water and a soft, clean cloth, sponge or brush. Then
rinse the lower part (4) thoroughly with cold water and put the filters and
the Water Cube back in.
• Approx. every 4 weeks (depending on the hardness of the water): First
remove the filters (15) and the Water Cube™ (18). In the case of limescale
deposits on the inside of the lower part (4), we recommend using the Stadler
Form Cleaner & Descaler (www.stadlerform.com/accessories). Alterna-
tively, you can use a household decalcifier or vinegar. Then rinse the lower
part (4) thoroughly with cold water and put the filters and the Water Cube
back in. For hygienic reasons, the filters (15) must be replaced every 2–3
months. Textile cover: Over time, dust will collect on the textile cover. You
can remove this using the soft brush attachment for your vacuum cleaner.
