Functions of the Cleaning Key
For that, the circulation valve to the HE as well as the milk solenoid valve close automati-
cally while the milk pump runs. The cleaning process is interrupted as soon as the display
shows the fault message „Milk/circulation valve“.
Prerinsing
During prerinsing the display shows:
In order to be sure that there is no remaining milk in the coil of the heat exchanger
anymore, 800 ml of water are automatically delivered into the coil and pumped out via the
mixer outlet valve. The mixer is then rinsed with a 500 ml water portion that is subsequently
drained off. The coil is rinsed for 5 seconds with 500 ml of water, i.e. the water in the mixer
jar circulates to the coil and is pumped out immediately afterwards. Now 800 ml of water
are delivered once again into the mixer jar via the coil and are drained off again via the mi-
xer outlet valve. Finally the mixer jar is rinsed with a 500 ml water portion that is subse-
quently pumped out.
Main rinsing
During the main rinsing process, 1,3 liters of water and
some detergent (in case the automatic feeder is equipped with
a detergent pump that has been activated in Setup) are delive-
red into the mixer jar. The water starts circulating. The
display shows:
Time starts running backwards from 10 to 0 minutes. Press
Start/Stop to cut off the cleaning process at any time.
After 10 minutes have lapsed, the liquid in the mixer jar is
pumped out via the mixer outlet valve.
Afterrinsing
In order to be sure that there is no detergent in the coil of the heat exchanger anymore, after-
rinsing starts running. 800 ml of water are automatically delivered from the coil into the
mixer jar and are then pumped out via the mixer outlet valve. The mixer is then rinsed with
a 500 ml water portion that is subsequently drained off. The coil is rinsed for 5 seconds with
500 ml of water, i.e. the water in the mixer jar circulates to the coil and is pumped out im-
mediately afterwards. Now 800 ml of water are delivered once again from the coil into the
mixer jar and are drained off again via the mixer outlet valve. Finally the mixer jar is rinsed
with a 500 ml water portion. This water too is subsequently pumped out.
During afterrinsing the display shows:
Electrodes and valves are checked automatically. 1,5 liters of
water are delivered into the mixer jar where they are stirred
for 20 seconds. After that, they are drained off via the mixer
outlet valve. This process should remove all residual foam
inside the mixer jar.
