just a tish NE of central ND | Heck. I'm just SO happy you are someone what WANTS to learn. Seems now day that a lot of people don't care to learn this kind of stuff anymore. The valves are double seating valves. Meaning they have a seat screwed all the way in. or all the say out. Crack them part way open to service the system. This opens the service ports.. Back them all the way out to close the system from leaking after servicing (to the atmosphere).. You can see them screwing outward/ inward when you turn them. Screw them all the way in to isolate the system from the compressor. That way you can remove the compressor(take bolted plate off the back of compressor) and leave the lines blocked off with those valves..
Never never, never never NEVER hook the refrigeration charging can up to the high side of the service valves or it can and will explode and kill you...... if the can starts getting warm instead of cold you are going to have a he77 of an accident.
Even leaving Freon cans on a car seat with the sun shining in on them can make them explode. I forgot some on the back seat one time and it put a can shaped dent on the roof of a galaxy 500 ford about 3/4ths a inch high right through the headliner and cost me some window repairs... |
