Wouldn’t you purge where the process hose connects the manifold set while the knobs on the manifold are closed off to the system. The only way I could see you purging where you did would be to have the hoses disconnected from the system using hoses with ball valves. If the hoses were actually hooked to the system with the process knobs open you would introduce air into the system.
i agree when i saw that guy do that the assumption was its under vacuum and ready for charging so he would have to purge the yellow hose either at the manifold or the valve on the in side to purge all air from hoses. that guy is going upset some new guys in the field when they find out the have a tone of air in the system and now it wont cool lol
I couldn’t figure out how to use this today on a brand new walk in install. Went back to the trusty cps scale. This is the most over engineered croc of shit I’ve ever had in my van. Should just leave it on the roof of my van and drive away
What's the actual benefit? This entire system depends on a technician not actually understanding how to charge a system and relying on this to charge it for him/her. Just learn how to charge an A/C and save your money.
does this work with the older 557s

The entire process just makes no sense.

Need to fix the app issues that happened on the last update guys. The 557s gauges have lost all connectivity to the app and this still isnt fixed !
