Functional Steps „Cleaning, Heat Exchanger“ (see chapter 15.2)
Heat exchanger cleaning consists of pre--cleaning, main cleaning and rinsing and has to be
carried out every day. During heat exchanger cleaning, all milk--supplying parts of the auto-
matic feeder (except for the suction hoses) are thoroughly cleaned to prevent creation of
milk deposits or other impurities.
The heat exchanger can also be cleaned automatically (see Menu „Cleaning, Settings“). If
the automatic heat exchanger cleaning is active, automatic mixer cleaning becomes no lon-
ger necessary, as the mixer jar will be cleaned, too.
Turn the program switch to 2 = Rinsing.
Press Arrow Up or Arrow DOwn to select submenu „Clea-
ning, Heat Exchanger“.
Press Arrow Right to move to the next screen.
Press Start/Stop. If the automatic feeder is equipped with a
detergent dosing pump that has been previously selected in
Setup, the display will show:
Enter the detergent amount and press ENTER to confirm the
input.
Pre--cleaning
The automatic feeder starts checking automatically whether
the short electrode is permanently earthed.
The cleaning process is interrupted as soon as a fault message
is displayed. See chapter „Alarms“.
If the short electrode is not earthed, the automatic feeder will
start checking whether the electrodes and the solenoid valves
are tight.
For that, the cleaning valve HE as well as the milk solenoid valve close automatically. The
milk pump starts running simultaneously. The cleaning process is interrupted as soon as a
fault message is displayed. See chapter „Alarms“.
In order to be sure that there is no milk left in the coil of the heat exchanger
anymore, 800 ml of water are delivered automatically into the coil and pumped out via the
mixer outlet valve. Then, the mixer is rinsed by a 500 ml water portion that is subsequently
drained off. The coil is rinsed for 5 seconds by 800 ml of water, i.e. the water in the mixer
jar circulates to the coil and is pumped out immediately afterwards. Now 1 liter of water is
