13.11.4 Putting the air conditioner into

operation

To prevent compressor damage on machines with an

air conditioner, the air conditioner should be put back

into operation after an extended standstill period.

This putting into operation ensures that the oil is dis-

tributed accordingly in the air conditioner.

- Start the diesel engine and let it run at idle

speed.

- Switch the air conditioner on.

- Set the temperature controller (1) to the lowest

1

temperature.

- Let machine run in idle speed for about 5-

125

10 minutes.

29685

The air conditioner can now be operated again as

usual.

86828

13.11.5 Precautions for protecting the air con-

ditioner during extended standstill periods -

DOMINATOR 130 with York compressor

- In the cold season, switch on the cab heater and

3

heat up the cab to around +21 °C.

On combines with air conditioner without heater,

possibly use an electric heater or similar to raise

the cab temperature to +21 °C.

2

- Operate the air conditioner for five to ten minutes.

1

- Shut off the air conditioner and switch off the

engine.

- Close the compressor service valves (1 and 2).

Screw on the caps (3) tightly.

- Ensure that the blade-type fuse (4) in the current-

126

carrying line to the electro-magnetic clutch of the

19297

compressor is definitely removed.

Running the compressor with the service valves

closed will result in damage to the compressor.

5

- Now fit the cap (5) so no water can penetrate into

the compressor.

Note: The blade-type fuse is located between the

4

engine and the grain tank.

- Do not weld any components of the refrig-

erant circuit and or in the immediate

vicinity of any parts of the refrigerant

circuit.

- Maximum ambient temperature for refrig-

erant is 80 °C.

- Check the moisture saturation at the

receiver/dryer (1).

The moisture saturation of the receiver/dryer is

1

exceeded when the blue ball in the sight glass has

turned pink, or the orange ball has become colourless.

- If necessary, change refrigerant.

- If required, replace filter receiver drier (1).
