I see a ProCooler there so I'll mention something for the record.

It is shipped with a "FACTORY VACUUM". This is so the internal desiccant in the drier does not absorb water from the ambient air and can then absorb water from your A/C system later! Water will cause your expansion valve to freeze among other things.

You will hear that vacuum suck when you open the drier fitting caps (not the jacket caps).

Thus you should NOT OPEN or install that ProCooler until about 10 minutes before you plan to evacuate your system... or you will just be wasting desiccant capacity and dramatically reducing the drier ability to absorb moisture like its supposed to.

It should be BIG BOLD on the instructions. DO NOT OPEN OR INSTALL UNTIL READY TO EVACUATE.

$300!!!
