ATTENTION!
Never fill hot water into the water tank.
Do not fill water into the hot device. Wait until it has cooled down.
Before the first use
1. Before using the coffee machine for the first time, circulate water 2 or 3 times
without coffee, to rinse the appliance (section "Coffee Preparation").
2. Due to the design of the appliance, after the first use, a small amount of water
remains in the water container. Take this into consideration when refilling the
tank with water.
3. The water tank should always be filled
with the amount of water that equals the
volume of the enclosed thermal jug.
The amount of coffee brewed will be the
same as the amount of water poured.
If, accidentally, the water tanks is filled with
an excessive amount of water, the excess
of water will flow through the overflow hose
(a).
Fig. 2
4. Before use, the thermal jug and filter basket with insert should be thoroughly
washed in warm water and a mild cleaning agent, and then rinsed with fresh
water and dried thoroughly after washing.
ATTENTION!
When brewing coffee without filter basket
insert, the paper filter may clog the outlet
opening of the filter basket and may make it
impossible for coffee to flow to the thermal jug.
After washing, the removable insert must be
fitted in the bottom of the filter basket, so that it
is not discarded accidentally when removing
coffee dregs.
Fig. 3
5. Wipe the appliance housing with a moist cloth and wipe dry with a soft cloth.

off and the red heating indicator light goes off.
The coffee is ready to be served.
10.Remove the thermo jug from the bottom plate.
11.Screw the lid onto the thermo jug.
Overheating protection
The appliance is equipped with the overheating protection. If overheating occurs
during dry operation or scaling, it engages and switches the appliance off. When the
cause is removed, the coffee machine may be switched on again in order to restore
its operational readiness, by pressing the RESET button at the rear side of the
appliance.
6 Cleaning
6.1 Safety Instructions for cleaning
•Before cleaning, disconnect the appliance from the power supply.
•Leave the appliance to cool down completely.
•Make sure water does not enter the appliance. Do not immerse the appliance in
water or other liquids during cleaning. Do not clean the appliance with a
pressurized water jet.
•Do not use any sharp or pointed, nor metal implements (knife, fork, etc.). Sharp
or pointed implements may damage the appliance, and when in contact with live
parts, they may cause electric shock.
•For cleaning, do not use any scouring agents that contain solvents nor corrosive
cleaning agents. They may damage the surface.

Cleaning
190184 17 / 24
EN
6.2 Cleaning
ATTENTION!
Always, prior to cleaning, moving or transport of the coffee machine,
empty the water tank.
WARNING!
Risk of burns!
Water in the water tank becomes very hot.
Drain the rest of water from the tank only when the appliance and water
has cooled down enough. To end with, tighten the drain screw.
1. Drain the water remaining in the water
tank with the use of drain screw (b) at the
rear side of the appliance (at the bottom).
2. After each use, clean the thermal jugs and
filter baskets with inserts with warm water
and mild cleaning agent.
3. Rinse the cleaned elements in fresh water
and dry.
Fig. 6
4. Wipe the housing of the appliance with a soft, moist cloth, and dry at the end.
5. Conduct the brewing process as described in section "Coffee Preparation"; do
not use ground coffee if the appliance has not been used for a prolonged time.

Cleaning
18 / 24 190184
EN
Cleaning the thermo jug
Hard water may leave white, mineral deposits inside the thermo jug. Coffee usually
colour the deposits and leave the brownish deposit. To remove these deposits,
follow the below indications:
–prepare a solution of hot water and descaling agent (art. No. 190065);
–leave the solution in the jug for 20 minutes;
–pour the solution out;
–rinse the thermo jug thoroughly several times;
–wipe the exterior of the thermo jug with a soft cloth;
–leave the thermo jug open to dry completely.
6.3 Descaling
NOTE!
To reduce limescale deposits, it is recommended to use filtered water!
CAUTION!
Injury hazard!
Use safety gloves and goggles during descaling!
Depending on the water hardness level in the place of usage, limescale may be
deposited inside of the appliance's elements during the operation of the coffee
machine. In order to maintain the appliance in the best possible condition, and to be
certain that every brewing process yields the best results, the appliance should be
descaled regularly.
If used extensively, in order to remove oils, coffee stains and stubborn deposits the
appliance must be thoroughly cleaned and descaled every two weeks.
1. For thorough cleaning, use commercial agents for cleaning coffee machines
available on the market. Follow the manufacturer’s instructions.
2. The descaling process, as described below, should be performed also when the
preparation of coffee takes longer than usually, the sounds of brewing start to be
more distinct or the coffee machine switches itself off, although there is still
water in the tank (e.g. in the case of very hard water).
3. For descaling the appliance we recommend the tried and proven agent:
Descaling agent Bartscher B15-30 (art. no. 190065).
