You need a vacuum pump to pump out the system before you charge it.
The charge has to be dead on or the system wont work, you'll need a regular gauge setup to charge it the refills don't work very well.
On mine the spread on the pressure is less than 10lbs pressure or the compressor wont start (Too low charge) or stalls (Too high charge.)
Cheers.
