Service and Maintenance of the Automatic Calf Feeder
open the de- -aeration 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.
Remove the water inside the stainless steel coil of the heat exchanger by means of
compressed air (1 bar). For that, put the nozzle for compressed air before the milk valve
and select submenu „Diagnosis" in main menu „Hand Functions". Move to menu „Milk
valve, open?" and keep the Enter key pressed until just air comes out of the water resp.
milk outlet.
Commissioning the automatic calf feeder once again:
When commissioning the feeder again, check whether there is enough water in the heat
exchanger.
Proceed as for first commissioning.
Fill the boiler of the heat exchanger with water.
- - You do not need to top up the boiler regularly in case some calves are fed with milk
that has been diluted with water or when mixer- - or HE cleaning has been activated.
In case calves are only fed with milk, top up the boiler of the heat exchanger with
water approx. every 3 months. Proceed as for first commissioning (refer to chapter
5.2, page 24, „Installing the Automatic Calf Feeder, Filling the Boiler of the Heat
Exchanger with Water").
