Evacuating

Danger!

Risk of explosion from welding or soldering work on closed air conditioning system. Risk of poisoning from inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant.

Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been discharged.

Cable for activation of solenoid

WF58.50-T-8330-01A

2

Detach protective caps from the pressure-side testing and filling valve (11) and from the suction-side testing and filling valve (12)

3

Connect pressure and suction line of the air conditioning extraction and recycling unit to the pressure-side testing and filling valve (11) and to the suction-side testing and filling valve (12)

Refer to the operating instructions for the air conditioning extraction and recycling unit.

Ensure that the pressure-side shutoff valve (3) and the suction-side shutoff valve (4) are unscrewed completely.

*WE58.40-Z-1002-22A

4

Evacuate air conditioning using the air conditioning extraction and recycling unit

Evacuate air conditioning circuit up to the maximum attainable vacuum, but for at least one hour.

If moisture has penetrated into the air conditioning circuit, evacuation must be continued for at least 8 hours.

Leak test

5

Switch off air conditioning extraction and recycling unit

Close valves of air conditioning extraction and recycling unit.

Closing the valves prevents the leak test from being distorted by the air conditioning extraction and recycling unit.

*WE58.40-Z-1002-22A

6

Read off vacuum display on the pressure gauge of the air conditioning extraction and recycling unit

Note vacuum pressure value

*WE58.40-Z-1002-22A

7

After waiting for 10 minutes, read off vacuum display on the pressure gauge again

Compare current vacuum value to the recorded vacuum value.

If a drop in vacuum is detectable:

Fill air conditioning without leak test

After filling the air conditioning system, check for leaky areas:

AR83.30-T-1777BAF

Inspect the refrigeration circuit for leaks.

Before repairing leaky area empty air conditioning system:

AR83.30-T-1209-01C

Discharge air conditioning system

Check for leaky areas again after the repair work:

AR83.30-T-1780BAF

Repeat steps 1 to 7.

8

Fill air conditioning system

Evacuate and do not carry out leak test.
