Air Conditioning (AC) System, General Instructions: General

Any leakage must be repaired immediately in order to prevent moisture entering the system.

Ensure the work area is kept dry and clean. Moisture and dirt will reduce the efficiency of the air conditioning (A/C) system.

Store compressor oil in a sealed container (compressor oil absorbs water).

When working on A/C systems, for example when replacing components, open ends must always be plugged immediately after undoing pipe or hose connections. When installing new components, leave the protective plugs in the holes until the component is actually needed. If dirt may have entered any component it must be inspected and cleaned.

If the car has been damaged in a collision it is important that every component in the system is inspected. Special attention must be paid to brazed joints. Cracked or deformed components must not be repaired.
