Precautions:

1. When removing the compressor, store it in the same position as it is mounted in the vehicle.

Failure to do so may cause lubricant to enter the low pressure chamber and cause compressor
damage.

2. Allow components stored in cool areas to warm to area temperatures before removing seals.

This prevents condensation from forming inside A/C components.
