Removing Electric Air-Conditioning Compressor

→ Avoid contact with refrigerant.

→ Wear personal protective gear.

→ Observe the safety regulations for working on air-conditioned vehicles and dealing with refrigerant.

→ Observe the safety regulations for extraction and filling systems.

→ Observe the instructions for repairing air conditioning systems and storing spare parts.

1. Open the holding clamp on the low-pressure refrigerant line in the engine compartment.
   1. 1.1. Unscrew M6 fastening nut -1-  .
   2. 1.2. Open the holding clamp -2-  and bend it up carefully.

   CAUTION: Escaping residual air

   • Risk of eye injuries

   → Wear protective goggles.

   NOTE: Opened refrigerant system for repairs.

   • Risk of moisture getting into the refrigerant system.
   • Risk of contaminating the refrigerant circuit.
   • Risk of saturation and irreparable damage to desiccator.
   • Irreparable damage to the desiccator can damage the compressor and evaporator.

   → After opening the refrigerant circuit, close off the lines/connections immediately using suitable stoppers.

   → The desiccator must be replaced if the air humidity is high and if the refrigerant circuit is left open for a long time.

2. Unscrew M8 fastening screw -3-  on the low-pressure refrigerant line -4-  and pull off the line. Close off the lines immediately using suitable stoppers.
