Pre - Infusion Function; Cleaning And Maintenance - Trebs Royal Serie Expertenhandbuch

PRE - INFUSION FUNCTION

The Trebs 24110 coffeemaker is equipped with a pre-infusion function to achieve a better quality brew.
The pre-infusion function schedules a short interval in water distribution to allow the dry ground coffee to reach
an optimal state of saturation. This makes sure that the coffee aroma is fully extracted into each cup.
Press and hold the On/Off switch (4) five seconds to switch between the default mode and the pre-infusion mode.
After five seconds the light will start blinking, indicating that the pre-infusion mode has been activated.
Press the On/Off switch (4) once more shortly to begin operation in pre-infusion mode (visible by a blinking On/
Off switch (4))
The device can be switched back to its default mode by pressing the On/Off switch (4) another five seconds. The
default mode is indicated by a steady light on the On/Off switch (4).
The chosen mode remains active until manually switched or the device is unplugged, upon start up the default
mode will be active.

CLEANING AND MAINTENANCE

Proper periodical cleaning and descaling will ensure years of service from the coffee brewer.
Always unplug the device and make sure the device has cooled down before the surface is cleaned.
Use a soft damp cloth without abrasive cleansers to clean the outside/warming pad.
To maintain the working efficiency of the Coffee maker and coffee quality, it is necessary to descale the coffee
maker periodically. The frequency of descaling depends on the quality of the water used and the amount of
mineral built up during usage. Trebs recommends descaling the device every two months.
1. Prepare a descaler mixture of water and descaler, suggested ratio is 4:1. Actual ratio depends on the brand
and concentration of the descaler used.
2. Pour the descaler mixture in the water tank (2) and close the water tank lid (1).
3. Make sure the removable coffee filter funnel (7) is placed correctly in the coffee maker and place the glass jug
(10) in the correct position in the filter holder (3).
4. Start operation by pressing the On/Off switch (4) and allow the coffee maker to run 1 cup of the descaling/
water mixture.
5. After 1 cup, turn the coffee maker off by pressing the On/Off button (4).
6. Allow the coffee maker to cool off for 15 minutes and repeat step 4 – 5 until the water tank (2) is completely
empty.
7. After cleaning, it is important to rinse the device thoroughly by operating the device with clean water at least
three times.
