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

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 with delivery. The
group cleaning with the ECM cleaning tablets can be carried out every week. The group cleaning powder is a bit more
fat-dissolving and can be used in intervals of two weeks or every week using only half of the packet content.
Follow the instructions as noted below:
1 Heat up the machine.
2 Put the blind filter into the filter holder.
3 Put a cleaning tablet into the filter holder.
4 Place the filter holder in the housing of the group.
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. 1 minute. 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 filter holder and the blind filter with fresh water. Then replace it.
10 Operate the group lever for approx. 1 minute. Then move it back into the lower position.
11 Remove the filter holder 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 to avoid strong calcification and expensive repairs. While
descaling, always take into account the hardness level 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)
perfectly suited for your machine.
Just follow the steps below:
1 Heat up the machine until the operational pressure has been reached.
2 Switch off the machine.
3 Empty the boiler by operating the hot water dispenser. Discharge the heat exchanger by operating the brew
group lever. Then close the hot water dispenser and coffee dispenser.
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. This automatically fills the empty boiler. Afterwards, operate the group lever until liquid
is discharged by the group. The heat exchanger will fill with the descaler solution.
