Maintenance - Profitec Pro 300 Bedienungsanleitung

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. Do not use a descaling agent containing sulfamidic acid
(also known as amidosulfonic acid). This acid is 6x stronger than citric acid an can affect the materials.
Please contact your supplier, as they will be able to recommend a proper descaling agent.
We recommend to descale the two boilers independently from each other.
Please proceed as follows:
1 Turn the machine on by switching the metal switch upwards. The coffee boiler is now being heated to the
preset temperature (reg. PID-display).
2 Mix the descaling powder with water according to the instructions and pour it into the tank.
3 Turn the coffee switch to the upper position and release about 400 ml water through the brew group. The
coffee boiler is now filled with descaling liquid.
4 Now clamp the portafilter with blind filter into the brew group and operate the coffee switch for about 20
seconds. Repeat this step twice and let the descaling liquid soak for about ½ hr.
5 Turn the steam boiler on.
6 After the steam pressure has been reached, turn the machine off and empty the water out of the steam
boiler by way of the hot water dispenser.
7 Turn the machine on, the steam boiler as well. The empty steam boiler is now being filled with descaling
liquid.
8 The machine heats both boilers to the preset temperature. Let the descaling liquid soak for about ½ hr.
after the operating pressure has been reached.
9 Unclamp the portafilter and empty the remaining descaler through the brew group by activating the
coffee switch.
10 Turn the machine off and empty out the steam boiler by activating the hot water release.
11 Empty out the water tank, rinse it thoroughly, fill with fresh water and place it back into the machine.
12 Turn on the coffee and steam boiler. This automatically fills the steam boiler with fresh water. When this
boiler is full, activate the coffee switch in order to fill the coffee boiler with fresh water until about 500 ml
water has been discharged through the brew group.
13 Refill the water tank.
14 Clamp the portafilter with blind filter back into the brew group and activate the coffee switch 3 times for
about 20 seconds. Then, often activate the coffee switch until the entire system has been flushed. Now
remove the blind filter from the portafilter.
15 Activate the coffee switch and flush fresh water through the brew group for about 60 seconds.
16 Turn the machine off and empty out the steam boiler by activating the hot water release. To refill the
boiler with fresh water, you have to switch the machine on again.
17 Repeat the flushing at a minimum of 5 times in order to flush both boilers.
18 Flush both boilers until clear, neutral smelling water comes out of both the brew group and the hot water
release.
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, such as 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 boilers 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. portafilter or drip tray when sending in the machine for
repairs / maintenance.
