Group Cleaning And Degreasing; Prophilactic Descaling - ECM Manufacture Casa IV Instruction Manual

7.2 Group cleaning and degreasing

A 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 every week.
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 coffee switch. The blind filter fills with water.
6 Operate the coffee switch in intervals of approx. 20 seconds, by the outlet connection will be shown.
7 Repeat point 6 several times until the water released by the outlet connection is clear again.
8 Remove filter holder again, rinse it with fresh water and place it back into the brewing group.
9 Operate the coffee switch. The filter holder is filled with water again. Repead this several times
10 Remove the filter holder and place a cup filter into the filter holder. Now the brewing group is ready for use again.
Caution!
Beware of hot spillings while cleaning the group.

7.3 Prophilactic 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 one sachet of the
descaler in it. Then proceed as follows:
1 Dissolve the descaler in water according to the instructions for use (see above) and pour the solution into the
water tank. Switch on the machine.
2 Release a total minimum of 400-500 ml of water from the group and from the steam/ hot water dispenser. Thus,
the boiler is filled with descaler. Then heat up the machine.
3 Place the filter holder with the blind filter into the group head and operate the coffee switch 3 times for about 20
seconds. Switch off the coffee switch after every operation. Thus, the expansion valve will be descaled.
4 After this process, let the descaler react for approx. ½ hour.
5 Release the remaining descaler solution by operating the coffee switch.
6 Switch off the machine, remove and clean the water tank and fill it with fresh water.
7 Switch on the machine and release approx. 400-500 ml of water from the group and the steam/ hot water valve
(switch pump/ hot water).
8 Repeat this process approx. 2-4 times to make sure that no descaler is left in the boiler.
9 Keep the coffee switch pressed 3 times for approx. 20 seconds, then switch it off again. Thus, the expansion valve
will be descaled. Then remove the blind filter from the filter holder.
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, gauges 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.
Please do not enclose loose parts e. g. filter holder or drip tray when sending in the machine for
repairs / maintenance.
