Good afternoon Yoreparo community. In this new post I am reviewing a 10 or 12 foot MABE refrigerator with 2 horizontal doors which lost all of the 134-A refrigerant gas, noticing that it has a service valve because it had been repaired before, pressurized with nitrogen at 150 psi and with the help of water, soap a flashlight and a mirror I began to look for the leak through all visible pipes, both next to the compressor, condenser and evaporator, after 30 minutes looking for I could not find anything, perform vacuum with 2 pump stages until it reaches -28 leave it for 30 minutes and did not run the needle, before recharging again add some red oil that is used to see future leaks or stains, refill the r134-A gas as the manufacturer's label says 136 grams, with an amperage of 1.9 as the label says, the refrigerator began to cool again. By discarding I think that it is possible that the leak is through the pipe that is embedded in the sides that is not visible I think it serves to prevent moisture, is what I have read, now well. IF THE LEAK IS THROUGH THE BUILT-IN PIPE, HOW MANY METER OF PIPE IS NECESSARY TO BE DONE BY THE OUTSIDE, WITHOUT LOSING THE MANUFACTURER'S SPECIFICATIONS OR REGARDING THE COOLING GAS CYCLE. ? THANK YOU

Hi. When the leak is in the inner pipe, a condensing grill must be adapted, it is the equipment that brings that outer grill that you can see and then adapt a capillary, when you get it you write to help you.

Hello Admg if the pipe you say is the one that heats the door frame is approximately 5Mt what you should attach back and diameter 3/16 or failing that if you don't get that diameter use 1/4
