The machine is designed and manufactured for domestic use. The manufacturer assumes no liability for consequences arising from commercial use, use not in compliance with its intended purpose or noncompliance with the operating manual. This machine is intended to make hot drinks as stipulated in the operating instructions.
This machine is intended for use in households and similar areas, such as staff rooms in ofﬁces and shops, as well as other work work-related facilities; also in farms, for use by guests in hotels, motels and bed & breakfast establishments. The machine may only be used for its intended purpose.
In case of long periods of absence, vacation etc., the machine must be emptied, cleaned and the mains plug must be removed from the socket.
When there is risk of frost, all residual water must be removed, see the section on „Evaporate remaining water“ on page 38.
The mains voltage must match the speciﬁcations on the nameplate. Only connect the machine to a grounded 3-pin wall socket. In the case of an incorrect onnection your warranty rights may be forfeited.
Do not damage the mains cord by placing it on or near hot objects or over
sharp edges. Do not allow the mains cord to hang down (risk of tripping). Do not touch the mains cord with wet hands. Do not pull the plug from the socket by pulling on the cable. If the mains cord shows signs of damage, do not start the machine.
When the mains cable of the machine is damaged it must be replaced by the manufacturer, the respective customer service or a similarly qualiﬁed person in order to avoid any hazards.

For health reasons, only ﬁll the water tank with fresh drinking water.
How to avoid injuries and scalds when using the machine.
Do not leave the machine unattended during beverage preparation. This machine can be used by children from the age of 8 years and older and by persons with reduced physical, sensory or mental abilities or who lack experience and knowledge provided they are supervised or have been instructed regarding the safe operation of the machine, and understand the resulting dangers.
Cleaning or servicing of the machine that is normally carried out by the user must not be carried out by children unless they are 8 years old or older and act under supervision.
The machine and its connection cable must be kept out of the reach of children younger than 8 years. Children must not play with the machine.
Never open the lever on the machine during the brewing, rinsing, cleaning or descaling processes. When a process has been completed and the lever is then opened, never hold your ﬁngers under the spout – there is a risk of scalding from remaining hot liquid dripping from the spout! When the brewing process has been completed, slowly open the lever in order to eject the capsule; do not bend over the capsule insertion opening (risk of hot liquid sprays).
Never reach with your ﬁngers into the capsule insertion opening – risk of injury!
Do not use the machine without drip tray and drip grating! Do not overﬁll the water tank. Never lift the machine by its lever.

Evaporate remaining water

With this function, any remaining water in the machine is evaporated and removed. This prevents any residual water freezing in the machine when the machine is transported or stored at temperatures below freezing point.
CAUTION
Extreme temperatures can cause damage to the machine (permitted operating temperature 10 – 45°C).
For this reason the machine
– must be protected against frost,
– must not be used at temperatures below 10°C,
– must not be used at temperatures over 45°C.
Procedure

If necessary, warm up the machine until it reaches room temperature.
Open and close the lever in order to eject any existing capsule.
Take out and empty the water tank.
Ensure that the machine is switched off.

WARNING
Risk of scalding! The evaporation process results in hot steam (up to 120°C) and hot water.
Do not reach under the spout and maintain a safe distance from the spout.

Hold the „small cup“ and the rinsing button depressed at the same time. Now press the on/off button. Evaporation starts and the „large cup“ button ﬂashes green.
After the evaporation process the machine switches off automatically.
Re-insert the empty water tank.
Empty and dry the drip tray and spent capsule container.
Use a dry cloth to wipe the front of the housing.

Frequently Asked Questions

Is the drink dispensing process delayed?

The machine will re-adjust the temperature for the requested drink.

Is the spent capsule container overfull and jammed?

Try to remove the spent capsule container by jogging the container gently to and fro.

Is the drink not hot enough?

Are all buttons ﬂashing at a fast rate?

Switch the machine off and remove the plug from the mains supply. If the problem persists, please inform Customer Service.

Is the drink not dispensed properly?

Do I have to descale the machine if I am using the water ﬁlter?

If the water ﬁlter is regularly changed, no descaling is necessary. Nevertheless, it is possible that mineral deposits occur depending on the water quality and the machine location. For this reason we recommend an annual cleansing/rinsing process using a K-fee® system descaler.

Does the machine suddenly switch off during a period of intensive use?

If the cooling-down period is too short, the machine switches itself off as protection against over- heating. In this case allow the machine to cool down for about 30 minutes before using it again.

Does the machine switch itself off?

The machine switches off automatically if it is unused for more than 5 minutes. Please remember that the machine uses power as long as it is plugged into the mains socket (< 0.5 W).

Do you wish to reset the machine to the factory settings?

The machine will only work with capsules marked with the K-fee® system logo.
