Given how incredibly expensive a compressor failure is to clean up and get out of the airconditioning system, I'd make double sure that thing didn't operate till I was ready to charge the system. The simplest way to do that, short of not installing it, is to not (I said NOT) to connect the clutch connector to the electrical system. That will let the pulley freewheel without engaging the compressor.
