Brew Group Cleaning And Degreasing; Prophylactic Descaling - ECM Technika IV Bedienungsanleitung

Cleaning as necessary:
Clean the steam and hot water valve after every use.
Clean the body when the machine is switched off and cold.
Depending on usage, please refresh the boiler water every 2 – 3 weeks by operating the pump switch and extracting
about 0.8L of hot water from the steam wand.
Use a soft, damp cloth for cleaning.
Never use abrasive or chloric detergents!
Empty the water drip tray regularly and do not wait until it is full.

7.2 Brew group cleaning and degreasing

A brew group cleaner (in powder or tablet form) is available at your specialised dealer. With this detergent, you can
clean and degrease the group very easily. The cleaning is carried out using the blind filter included in delivery. The
group cleaning with our tablets can be carried out after approx. 150 cups.
Follow the instructions as noted below:
1 Heat up the machine.
2 Put the blind filter into the portafilter.
3 Pour ½ spoon of detergent into the blind filter or put a tablet into the portafilter.
4 Place the portafilter in the group head.
5 Operate the group lever. The blind filter will fill with water.
6 Let the detergent react, moving the group lever into the middle position. (Do not move it into the lower position.)
7 Move the lever into the lower position after approx. 40 seconds. This way, the fats and oils can be discharged by
the infusion cylinder.
8 Repeat points 5-7 several times, until only clear water is discharged by the infusion cylinder.
9 Rinse the portafilter and the blind filter with fresh water. Then replace it.
10 Operate the group lever for approx. one minute. Then move it back into the lower position.
11 Remove the portafilter and repeat point 10. After this, the brew group is ready for use.
Caution!
Beware of hot sprayings while cleaning the group.

7.3 Prophylactic descaling

To avoid damages due to lime residues, a prophylactic, regular descaling may be required. If you
operate your machine with a direct water connection, contact your specialised dealer before
undertaking this measure. For machines with water tank use, follow our descaling instructions.
Doing so will protect your machine against expensive repairs.
An already calcified machine may only be descaled by your specialised dealer because a partial
disassembling of the boiler and the tubing will be necessary in order to prevent the system from being
blocked by lime residues. A late descaling can cause substantial damage to the machine.
A regular descaling of the machine is recommended in order to avoid calcification and expensive repairs. While
descaling, always take into account the hardness degree of the water. It is very important to use a sparing descaler
which does not affect the metal. You can purchase a descaler in powder or tablet form perfectly suited for your
machine at your specialty dealer. Just fill the water tank with fresh water and dissolve one bag of the descaler in it.
Then proceed as follows:
1 Heat up the machine until the operating pressure has been reached (1.0-1.2 bar).
2 Switch the machine off.
3 Empty the boiler by operating the hot water dispenser. Then close the hot water dispenser again.
4 Mix the descaler with water according to the instructions and put it into the water tank.
5 Switch the machine on. Thus, the empty boiler is automatically filled with descaling liquid.
