Never allow the mains cable to loosely hang down. The mains cable could pose a tripping hazard or
become damaged.
U
Protect the C8 from weather and direct sunlight.
U
Only connect the C8 to a mains voltage corresponding to that stated on the rating plate. The rating
plate is located on the underside.
U
Connect the C8 directly to a domestic power socket. Using multi-socket adapters or extension cords
may cause overheating.
U
The surface of the heating element and outer enclosure remains hot after use and the outside of the
appliance may retain heat.
U
Do not use alkaline or alcohol-based cleaning agents; only use mild cleaning agents and a soft cloth.
U
Do not use any coffee beans treated with additives or caramelised coffee beans.
U
Only fill the water tank with fresh, cold, non-carbonated water.
U
Switch the machine off with the On/Off button
Q
if you are going to be absent for a longer period of
time and remove the mains plug from the power socket.
U
Only use original JURA maintenance products. Use of products that are not explicitly recommended
by JURA could damage your C8.
Danger of electric shock
Water conducts electricity. Do not bring water and electricity into contact with one another:
U
Never touch the mains plug with wet hands.
U
Do not immerse the C8 and/or mains cable in water.
U
Do not put the C8 or any individual parts in the dishwasher.
U
Before cleaning, switch the C8 off with the On/Off button
Q
. Always wipe the C8 with a damp cloth
rather than a wet one, and protect it from prolonged exposure to water splash. The C8 must not be
cleaned with a jet of water.
U
The C8 is not suitable for installation on a surface where a jet of water can be used.
Danger of burns, scalding and injury
U
Do not touch the spouts during operation. Use the handles provided.
U
Optionally, your C8 can be remotely operated using mobile devices. When preparing a product or
initiating a maintenance programme, make sure that other people are not put at risk – for example,
through contact with the spouts.
U
Be careful to ensure that the dual spout is correctly installed and clean. Otherwise parts may come
loose. There is a danger of parts being swallowed.
