The ONLY reason a system requires gas added or total re-gas is because gas has leaked out and once that refrigerant
leaks out air (along with moisture) can and does contaminate the system. This being new it could have been in a zero gas pressure situation with a leak for some time.
The tech should have located and repaired the leak, replacing the filter dryer and evacuated the system before adding refrigerant to suction gauge pressure.
Not following this correct procedure won't necessarily prevent the system from running but can greatly reduce its longevity and
power efficiency.
If you are going to risk adding car air-con grade R134a refrigerant, at least avoid any cans that have any additives at all, regardless of how 'you bute' the wrap on the can says it is!

Pete what do you recommend he do? Maybe you do not understand the
mechanic does not speak
English. And maybe a experienced tech is 1000 miles away. I have run
training classes down island where mechanics make only ten dollars a day. Your
advice is like telling him to shoot himself in the foot and he will feel better.
When we get a report back confirming system is performing well and no
leaks Dehydration in a few months might be a good idea but defiantly not a replacement of filter dryer. Risking a solder to line is old
school for suspect moisture.
