Service and Maintenance
16.1.2 Carrying Out a Regular Check Routine
:
Measure the milk temperature by means of a precision thermometer.
:
Check the calibration of milk powder at least after each new delivery.
:
Check the calibration of the components:
Deviations of the amount of milk and water:
-- in case of deviations with rising tendency (more than 500 ml are dispensed), carry out
a new calibration.
-- in case of deviations with falling tendency (clearly less than 500 ml are dispensed)
due to milk deposits in the heat exchanger, repeat the circulating cleaning process. If
necessary, use another cleansing agent but do not overdose it!
Carry out cleaning by means of a cleaning sponge or a hose--cleaning pistol. If the
cleaning sponge gets stuck, connect a high--pressure cleaner. Use the high--pressure
cleaner only with cold water and slowly raise pressure.
If these measures do not show any improvement, check whether the milk pump is
running. Insufficient pump pressure may reduce the liquid amount, too.
16.1.3 Shutdown
Before shutdown:
:
Turn the thermostat for minimum operating temperature and the heating thermostat
entirely counter clockwise.
:
Turn the main switch „ON/OFF“ to position „O“ and pull the mains plug to switch the
automatic feeder off.
After decommissioning:
:
The automatic feeder has to be in a dry location.
:
Keep the connections on the control unit closed by means of closing caps.
If not, moisture may penetrate the control unit.
:
Do not leave milk or rinsing water in the system.
Rinsing residues may affect the metal parts after long storage. Therefore, thoroughly
rinse by means of clear water after the last cleaning process and drain off the remaining
water. For that, remove the front cover of the milk pump and wait until the fluid drains
off entirely.
:
Let the water flow out of the heat exchanger. For that, remove the water hose located
between the solenoid water valve and the boiler of the heat exchanger and open the
deaeration screw of the circulation pump -- if available -- in order to make the water run
out.
In case of frost risk:
:
Let the water flow out of the solenoid valves and the pressure reducer.
