Prophylactic Descaling - ECM BARISTA Instruction Manual

Follow the instructions as noted below:
1 Heat up the machine.
2 Put the blind filter into the filter holder.
3 Pour ½ spoon of detergent into the blind filter or put a tablet into the filter holder.
4 Place the filter holder in the group head.
5 Operate the group lever. The blind filter fills 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. In this way, the fats and oils can be discharged
by the infusion cylinder.
8 Repeat points 5-7 several times, until only clear water will be discharged by the infusion cylinder.
9 Rinse the filter holder 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 filter holder and repeat point 10. After this, the group is ready for use.

12 Prophylactic descaling

A regular descaling of the machine is recommended to avoid strong calcification and expensive repairing. 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. At your specialised dealer, you can purchase a descaler (in powder or tablet form)
which is perfectly suited for your machine. Just fill the water tank with fresh water and dissolve the descaler in it.
Then proceed as follows:
1 Heat up the machine until the operative pressure has been reached.
2 Switch off the machine.
3 Empty the boiler, operating the hot water dispensing. Discharge the heat exchanger, operating the group lever.
Then close the hot water dispenser and finish coffee dispensing.
4 Dissolve the descaler in water according to the instructions for use (see above) and pour the solution into the
water tank.
5 Switch on the machine. Thus, the empty boiler will be filled automatically. Afterwards, operate the group lever
until liquid is discharged by the group. The heat exchanger will fill with the descaler solution.
6 Place the filter holder with the blind filter into the group head and operate the group lever 3 times for about 20
seconds. Move the lever into the lower position after every operation. Thus, the expansion valve will be descaled.
7 After this process, let the descaler react for approx. ½ hour.
8 Release the remaining descaler solution by operating the group lever.
9 Switch off the machine and empty the boiler by operating the hot water dispenser. (It is recommended to
unscrew and remove the nozzle of the hot water dispenser so that no dirt can be accumulated inside the nozzle.)
10 Pour fresh water in the water tank.
11 Switch on the machine. The boiler refills automatically with fresh water.
12 Refill water in the water tank.
13 Operate the group lever for 3 times. Move the lever into the lower position after every operation. Thus, the
expansion valve will be rinsed. Then remove the blind filter from the filter holder.
14 Operate the group lever for approx. 60 seconds in order to rinse the heat exchanger.
15 Repeat point 9 – 11 three to five times in order to rinse the boiler.
Important: These descaling instructions are only meant for prophylactic descaling. Please do not descale the machine
if it is already calcified. While descaling the machine, the lime residues can plug several components, like valves, gauge
etc., causing damage to your espresso coffee machine. In this case, please contact your specialised dealer. It is probable
that a professional descaling has to be carried out which requires the disassembling of boiler and tubing.
Damage to persons or to the material, caused by calcification in and at your machine, is not subject to the producer's
liability.
In this case, also the warranty expires. Machines will be only accepted for repair after foregoing technical advice and
written acknowledgement.
