You should keep the dryer sealed up with the plugs it comes with until your ready to assemble the whole system after getting you're hoses set. The dessicant in it will absorb any moisture in the air and become saturated, then it can't do it's job for your system charge. Mine came with a 2 piece bracket and hose clamps that can be used to mount in various places. When the system is charged, you watch the sight glass on the top of the dryer for bubbles. When they stop wait 5-10 seconds and then stop charging, it's full. It should be evacuated for an hour with an AC vacuum pump before charging. If your compressor comes with the PAG oil in it you should only add 1 more ounce to the system. R134a cans are available with PAG oil in it. 1 can of that and then straight R134a. If taking it to a shop then they "should" know, but remind the Tech because I'm sure they've never done one of these before. All the cars they work on have a label that tells them how much refrigerant and oil to put in the system.
