Prophylactic Descaling - Profitec Pro 500 Bedienungsanleitung

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 or powder into the filter holder.
4 Place the filter holder in the housing of the group.
5 Operate the brew group lever. The blind filter will fill with water.
6 Let the detergent react, moving the brew 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 through the infusion cylinder.
8 Repeat points 5-7 several times, until only clear water is discharged through the infusion cylinder.
9 Rinse the filter holder and the blind filter with fresh water. Then replace it.
10 Operate the brew 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 brew group.

7.3 Prophylactic descaling

A regular descaling of the machine is recommended in order to avoid strong 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 specialised dealer. 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 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 and pour the solution into the water tank.
5 Switch on the machine. This automatically fills the empty boiler. Afterwards, operate the brew group
lever until liquid is discharged by the group. The heat exchanger will fill up with the descaler solution.
6 Place the filter holder with the blind filter into the housing of the group and operate the brew group lever 3
times for about 20 seconds each time. Move the lever into the lower position after every operation. This
descales the expansion valve.
7 After this process, let the descaler react according to the manufacturer's instructions.
8 Release the remaining descaler solution by operating the brew 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 accumulate inside the
nozzle.)
10 Pour fresh water into the water tank.
11 Switch on the machine. The boiler automatically refills with fresh water.
12 Refill the water tank with water.
13 Operate the brew group lever 3 times. Move the lever into the lower position after every operation. This
rinses the expansion valve. Then remove the blind filter from the filter holder.
14 Operate the brew group lever for approx. 60 seconds in order to rinse the heat exchanger.
15 Repeat points 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
certain components, such as valves, gauges etc., causing damage to your espresso coffee
machine. In this case, please contact your specialised dealer. It is likely 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 on your machine, is not
subject to the manufacturer's liability.
In this case the warranty expires as well. Machines will only be accepted for repair after
previous technical advice and written acknowledgement has been given.
Please do not enclose loose parts e. g. filter holder or drip tray when sending the machine in
for repairs / maintenance.
