Is the pure green one that runs out of the power chord the only wire that needs to be connected to the base for it to be grounded? If so can I remove the green and yellow one
yes, so it seems.

The yellow green wire grounded the termostat.... since you don't have it anymore it's kind of obvious that it isn't needed

left a black and white wire hanging
they are live (I mean one of them is) so it isn't the best idea to keep it that way

that's how my one is, the black one is steel made to take higher pressure.

Poland, thanks for your help, I'll disconnect the two hanging wires and the green yellow wire.

Crna, cool, doesn't look like a standard size so I might need to do a homemade compression fitting.

Most of those small made in China water coolers use a small low HP compressor with metric tubing sizes.

Low HP? How much pressure do you think it will get to?

Low Horsepower. The pressure will be the same because it runs the same Freon and temperatures as a fridge. It will just take a long time. Some of those are using 60 watt motors instead of ~300 watt motors of a fridge. They can take up to 5X longer to pump up the same size chamber as a fridge. Most fridges are in the 1/4 to 1/3 HP size. Most water coolers for home use are much smaller. Does the compressor list a power rating in either Watts or HP?

It doesn't say on the compressor but I looked up the model number.

1/20th HP.. Makes my small nailer 1/3HP shop compressor look huge. This is way smaller than a refrigerator.

A low temp is normal for a fridge or water cooler compressor. It expects low inlet pressure. A high temp is normally used for air conditioners and applications where the cold side is much warmer than a fridge or water cooler. If you cascade that off a shop compressor keep the inlet pressure below about 50 PSI.

I'll keep it at about 30 psi. There isn't that much flow out the output so I think a little help from the shop compressor will be very helpful.
