prior to first use

Before using the coffee machine for the first time, proceed as follows: Carefully unpack your coffee machine and remove all packaging material and possible promotional stickers. Keep the packaging (plastic bags and cardboard) out of reach of children. After unpacking the appliance, carefully check it for external damage that may have occurred during transport.
Place the coffee machine on a flat, stable and heat-resistant surface. It is best to clean the interior of the new coffee machine prior to using it for the first time. Clean the appliance as described in section CLEANING AND MAINTENANCE. Then fill the water reservoir with cold water up to the 1.25L mark and allow the appliance to make two or three runs without coffee. The appliance will not function when switching it on with an empty water reservoir, the indicator led at the On/Off button will flash.

making coffee

Check that the voltage stated on the information plate matches the voltage used in your region. Place the coffee machine on a flat, stable and heat- resistant surface. Insert the plugin an earthed wall socket.

Raise the cover of the water reservoir and – using the glass jug – fill the reservoir with cold water to the required level (0.25L to 1.25L = 2 to 10 cups). Do not fill the reservoir above the 1.25 mark. Place the cover back on the reservoir.
Remove the filter holder from the appliance. You do this by first removing the cover and then rotating the filter holder counter-clockwise by the handle. Place a paper coffee filter (size 1 x 4) of which the edges have been folded back in the filter holder. This prevents the filter bag from folding inwards and closing. Add the required coffee (extra-fine grind) and softly shake it to flatten out the coffee. For 10 cups, according to taste, you can use 5 to 6 measuring spoons of coffee, or 6 grams of coffee per cup.
Fasten the filter holder in the appliance again, making sure it is properly positioned, and then close it with the cover.
Place the glass jug on the hot plate.
Warning: Ensure the water outlet, filter holder and glass jug are properly positioned before you start making coffee, so that no hot water can be released while making coffee. The water outlet must be placed firmly on the riser tube in the centre of the water reservoir and the filter holder must be properly secured. Do not remove the water outlet, filter holder and/or glass jug while making coffee. This could result in personal injury and/or damage to the appliance.
Open the coffee strength controller by turning it clockwise. Adjust the coffee strength controller in accordance with the volume of water in the water reservoir. See section Controlling the coffee strength for more information.
Switch on the appliance by pressing the On/Off button. The indicator led lights up and the coffee will be made. The hot plate under the glass jug is now switched on automatically.
Once the filter process has been completed, you must turn the coffee strength controller count-clockwise to the drip stop indication ( ). Remove the glass jug from the hot plate and pour the coffee.
Attention: When the water reservoir is empty, there can still be water in the filter. The filtering process is only completed once all the water has passed the filter.
Coffee tastes best immediately after it has been made, so do not wait too long before serving. The glass jug can immediately be placed back on the hot plate or you can pour the coffee into a thermos jug.

controlling the coffee strength

This coffee machine comes with a coffee strength controller. By means of this controller, you determine how fast the water flows through the coffee (extra- fine grind), which affects the strength of the coffee. When making a small amount of coffee, you must select a low flow speed, so that the coffee has sufficient time to acquire taste. Contrary, in the case of a large amount of coffee, the flow speed should be higher. Adjust the coffee strength controller in accordance with the volume of water in the water reservoir, between 1.25L and 0.25L.
Attention: When you turn the coffee strength controller to a lower position than 0.25L, you are activating the drip stop
Warning: When setting the coffee strength too low in relation to the amount of water, the coffee filter could overflow.

pause

If you want to interrupt the coffee making process, in order to pour a few cups for example, you must press the On/Off button to switch off the coffee machine temporarily. Turn the coffee strength controller to the drip stop ( ) position to prevent the appliance from continuing to drip. You can resume the coffee making process by pressing the On/Off button once more, after which the indicator led lights up. The coffee strength controller must be turned to the required strength again. If there is insufficient water in the water reservoir, no coffee can be made and the indicator led at the On/Off button starts to flash.

switching off

After use, always switch off the appliance by pressing the On/Off button. The indicator led switches off.
If you do not switch off the appliance after making coffee, the appliance will keep the coffee warm for about 40 minutes. After these 40 minutes the coffee machine switches off automatically. Then remove the plug from the socket.
Attention: After making coffee, do not forget to turn the coffee strength controller to the drip stop ( ) position, to prevent the appliance from continuing to drip.
Allow the appliance to cool down properly and then remove the paper filter bag, throw it away and clean the filter holder. You must also remove any residual water in the water reservoir to prevent scaling. This is done as follows: Make sure the appliance is off and has fully cooled down, remove the plug from the socket, remove the water outlet, filter holder and glass jug from the appliance and then hold the appliance upside down above the sink. Then place back all components correctly in the appliance.

clock and timer function

To have the coffee machine brew coffee automatically at the required time, you must set the clock to the current time.

By means of the Hour and Minute buttons you are able to set the current time (24 hour display).
Press the Auto or On/Off button to confirm the time. The word CLOCK in the screen stops flashing, the time has been set.
Press the Auto button twice in quick succession, the word TIMER starts to flash in the screen.
By means of the Hour and Minute buttons you can set the time at which the coffee machine should start making coffee (24 hour display).
Press the Auto button to confirm the time. The word TIMER in the screen stops flashing, the time has been set. After 5 seconds the current time is shown in the screen again. When you hold down the Auto button, you are able to see the set time for the timer.
Press the Auto button once more, the indicator led lights up. The timer function is switched on and the coffee machine will now make coffee at the time set by you. Once the set time has been reached, the indicator led switches off and the indicator led at the On/Off button lights up.

If you want to switch off the timer function after setting it, press the Auto button once more, after which the indicator led switches off and the timer function has been switched off. You can adjust the set time by following the above-mentioned steps again.

cleaning and maintenance

Regularly clean the coffee machine. This is not only beneficial for the life span of the appliance, it also ensures optimum use of the appliance and, of course, good-tasting coffee.

Cleaning should involve the following:

Prior to cleaning, always check that the coffee machine is switched off, and cooled down and that the plug has been removed from the socket.
Remove all separate components from the appliance. Remove the filter holder by first removing the cover and then loosening the filter holder anti-clockwise.
After each use, clean all separate components in hot water and a mild washing-up liquid. Then rinse thoroughly with hot water and wipe dry.
Regularly clean the outside of the appliance and the hot plate with a slightly damp cloth and then wipe it dry with a dry cloth
Place back all components correctly in the appliance.

de-scaling

Regularly de-scale your coffee machine. The de-scaling intervals depend on the hardness of the mains water and the frequency at which the coffee machine is being used. Due to scaling, the heating element can become obstructed. This causes overheating, as a result of which the coffee machine is switched off automatically as a safety precaution and will no longer function. The coffee recommend de-scaling the appliance after making coffee 60 times. You can de- scale the coffee machine with a special de-scaling agent for coffee machine or with kitchen-grade vinegar. If you use a special de-scaling agent for coffee machines, you must observe the instructions on the packaging of this agent.

When using kitchen-grade vinegar, proceed as follows:

Switch off the appliance by pressing the On/Off button. Remove the plug from the socket and remove all separate components.
To remove any remaining water, hold the appliance upside down above the sink.
Place an empty filter bag in the filter holder and place all separate components back in the appliance. Fill the water reservoir with clean, cold water and cold kitchen-grade vinegar up to the 1.25L mark. The water and kitchen-grade vinegar ratio should be 4:1.
Switch on the appliance by pressing the On/Off button. Press down the On/Off button for approximately 3 seconds, the icon
will flash on the display. Press the On/Off button again to start the de- scaling process.
The de-scaling process has been completed when the water reservoir and coffee filter are empty. Empty the glass jug and remove the filter bag from the filter holder. Repeat steps 1 and 2 to allow any remaining water to run out of the water reservoir and place all separate components back in the appliance.
After de-scaling, allow a full reservoir of cold water to flow through the appliance at least 3 times, to remove all de-scaling liquid and vinegar residues and thus prevent a sour taste in the coffee.

Caution! If the coffee machine has not been used for some time, e.g. due to vacation, it is recommended to remove and clean all separate components. Then place the cleaned separate components back in their place and allow the coffee machine to make one run with clean water. In this way you will prevent a possible foreign taste.
