This is the first of a three part series on service valves and installing the gauges.
As the students start to learn the refrigeration cycle one of their tasks is to install the gauges onto a refrigeration system. Before they can do the task they need to understand how the gauge works, how the service valve is constructed and the three positions of the service valve. Backseated, Frontseated & Cracked.
I do not like the way this video turned out and it is the first in a three part series so it needs to be posted so the video that follows: "Installing the Gauges on an AC System with Low Loss Fittings" makes sense. I will redo in a class next week and re-post.
