first week on hvac jobsite: accidentally set the manifold to 500 psi

started my first real hvac gig last monday, thought i had the gauges set right on my yellow jacket manifold for a simple r-410a recharge. turns out i bumped it to 500 psi and the line started hissing like a pissed off cat, had to shut everything down quick before it blew. boss just laughed and said happens to everyone, but i felt like a total idiot in front of the crew. watched a video from hvac school on youtube to double check my steps tonight, bryan orr explains it way better than my training manual. anyone got tips for not screwing up basic evacuations as a newbie? im using a ridgid pump but still getting moisture issues sometimes. dont wanna be the guy holding up the whole install.

proud of you for catching it quick, thats how you learn without a real disaster. stick with it, first year is all about those little wins building up.
