Removing Manifold Gauge Set

When A/C system has been charged with a specified amount of refrigerant, remove manifold gauge set as follows:
1. Close low pressure-side valve of manifold gauge set. (The high pressure-side valve is closed continuously during the process of charging.)
2. Close refrigerant container valve.
3. Stop engine.
4. Using shop rag, remove charging hoses from service valves. This operation must be performed rapidly.

WARNING: High pressure-side is naturally under high pressure.
So, care must be used to protect your eyes and skin.

5. Put caps on service valves.
