Some posts frighten me. This is one of them.

The new refrigerants should not be charged in the vapour state (gas). Assuming that this is a new install, of course.

By the age of the poster I would hope that this is a question he has been set by someone on a course he/ she is sitting and that they are not sitting, as we type with gauges in hand staring at at vrv with no refrigerant left. . Lets hope so anyway;)

Had a tradesman trying to teach me how to charge a system when i was an apparentice and it wasn't charging. On closer inspection i had to point out his gauges were connected to the discharge.

Gee that made me feel smart when i told him that.

and that's probably the most minor thing he had done.
