CAUTION:
Only move the water tank up or down vertically. When filling the water tank with
the water tank still installed, ensure not to spill any water on the housing of the
appliance. Always wipe off spilled liquids immediately. Do not use a glass vessel
for purging the system! Due to the local heating up during the purging process,
even heat-resistant glass could crack.
Important: The water hardness is crucial for the frequency of descaling. You deter-
mine the water hardness correctly and descale the appliance in time to avoid
damage and high energy loss due to excessive deposits of lime (see: 'Adjusting
the Water Hardness').
1. Ensure that the water tank is filled with clear, cold water up to the MAX filling
level. You may leave the water tank within the appliance for filling. Remove the
water tank lid, and pour in the water via a jug, ensuring not to spill any water
on the housing of the appliance.
Alternatively, you can fill the water tank by removing the complete water tank
from the rear of the machine. Grasp the water tank at both sides and pull it out
upwards. Ensure that the exterior of the water tank is completely dry, before sli-
ding the water tank vertically down at the back of the machine.
2. Connect the machine to a suitable mains power supply (see: 'Important Safe-
guards for Electrical Appliances'). Press the power button to turn the espresso
machine on. The power button flashes, while the machine is pre-heating the
water system. Wait, until the power button is illuminated continuously.For the
first use or after an elongated period of storage, purge the water system: Place
a heat-resistant bowl made of china or metal (minimum capacity: 1/2 litres) on
the drip tray. Point the steam wand into the bowl.
3. Turn the hot water/steam switch at the right side of the machine clockwise to
start the hot water function. Wait until the water flow stops automatically. The-
reafter turn the hot water/steam switch back to the vertical position. Press the 2
cups button to purge the group head. The appliance will complete this function
automatically.
4. Repeat step 3 until the filling level in the water tank drops to approx. 5 cm. During
this procedure, do not forget to empty the bowl in time.
5. If required, fill the water tank again up to the MAX filling level (see step 1). The
appliance is now ready for extracting espresso.
For removing or installing the water tank, do not tilt the water tank.
