So .. the performance of the system is sub par ..
I can start it .. and it blows cool .. but not cold ..
perhaps this is all because I have not vacuumed the system
1) for 30 minutes
2) at at least ~ 30 in. Hg
(Mercury or quicksilver[from the Roman god Mercury], metallic chemical element; symbol Hg [Lat. hydrargyrum=liquid silver]; at. no. 80; at. wt. 200.59; m.p. -38.842°C; b.p. 356.58°C; sp. gr. 13.55 at 20°C; valence +1 or +2. Mercury was discovered in antiquity, and was known to the ancient Chinese, Hindus, and Egyptians, but was not recognized as an element. It was used as a medicine by Paracelsus. It was first recognized as a chemical element (in the modern sense) by A. L. Lavoisier about the end of the 18th cent.
[ Sorry about the above but I wanted to verify that Hg was the proper element symbol] - as long as we're all getting
advanced discussion regarding AC, why not !?
And since we're learning things , why not the vacuum
discourse as well ?
vacuum, theoretically, space without matter in it. A perfect vacuum has never been obtained; the best man-made vacuums contain less than 100,000 gas molecules per cc, compared to about 30 billion billion (30?1018) molecules for air at sea level. The most nearly perfect vacuum exists in intergalactic space, where it is estimated that on the average there is less than one molecule per cubic meter. In ancient times the belief that ??nature abhors a vacuum? was held widely and persisted without serious question until the late 16th and early 17th cent., when the experimental observations of Galileo and the Italian physicist Evangelista Torricelli demonstrated its essential fallacy. Torricelli obtained a nearly perfect vacuum (Torricellian vacuum) in his mercury barometer. A common but incorrect belief is that a vacuum causes ??suction.? Actually the apparent suction caused by a vacuum is the pressure of the atmosphere tending to rush in and fill the unoccupied space. There are various methods for producing a vacuum, and several different kinds of vacuum pumps. have been devised for removing the molecules of gas or vapor from a confined space. In the rotary oil-sealed pump a rotor turning in a cylinder allows gas to enter through an inlet valve from a space to be evacuated and then pushes it through an outlet valve into the atmosphere. In the oil or mercury diffusion pump, gas enters the pump through an inlet and is then swept toward an outlet by heavy, fast-moving oil or mercury vapor molecules. The outlet is connected to a rotary pump that expels the gas into the atmosphere. A cryogenic pump removes gas from a container by condensing the gas molecules on an extremely cold surface in the container. An ion pump consists of a chamber containing a source of electrons that are used to bombard gas molecules from a container to be evacuated. Collisions between the electrons and gas molecules ionize the molecules, causing them to be drawn to, and held by, a collector in the pump. The first vacuum pump was invented by the German physicist Otto von Guerricke in 1650. There are many practical applications of vacuums in industry and scientific research, e.g., in vacuum distillation, vacuum processing of food, in devices such as the vacuum tube, vacuum bottle, and barometer, and in research machines.

I observed with my UV pen light and goggles last night that there is trace r134A around the seal area , I can see a ring around the spring, but this could be from the previous UV charge as stuff spilled out when I pulled the connector apart to replace the O-rings -
As others' have posted, the performance of the system is sub-par without the removal of air and water vapor from the closed system -- until I have eliminated the most obvious
methods (vacuuming system as part of the procedure when a part is replaced) I shouldn't presume the system is good.
I haven't done anything at the high side port of the system,
in fact the cap was missing & I have it taped up with electrical tape. Is this bad ? Does it need the special cap to be able to expel at certain times ?
So, I have this old refrigerator pump -- It is more like a 1/2 HP motor belt driving what looks like a air compressor cylinder (they made them like this in the 50's I believe - the newer ones have a more efficient rotary pump) ..
I will play with it and dump tons of time into making fittings to be able to suck the system dry .. because, this must be the last line of defense this system has in not working ! Boy I'm learning alot, don't have much of a life, but just really making headway on making a mess.
