Agreed system will have moisture in the refrigerant, that type is no longer allowed to be sold in France and probably the rest of Europe due to the health risks (freezing, at least he wore gloves) and the release of greenhouse gas. You have to have the system tested and commissioned by a professional and cannot even buy one unless this has been paid for in advance.
Wothout vacuum? forget it, rubish installation!
