Good job 👍
Thx for the video!
Nice job..i am the one subcsriber in your channel..
Is all the refrigerant out or closed off at the king valves? My system has 36 lbs of R134, and I'd like to know if I need to recover my refrigerant first?
merci
How to drain freon properly? I want to run it at 75# only due to sw vooling water high temp(saudi +33c). I have suct=5.0bars. As per freon 407c table I want to drain down to 4.0 bars. What is the correct way to drain it to the atmosphere? My condenser doesn't have drain point at its top, so I can't even deairate it.
How much discharge pressure
I think the discharge pressure is too high because now you are facing the summer so first of all clean the condensers and check the discharge pressure. suction pressure depends on discharge pressure and room temperature.
You can do this if you want. You can recover with the suction side and you can also recover with the liquid line. If you don't have a recovery machine, try releasing some gas.
@ACRWorldsl disch pressure= 19.5b at 50% capasity, with a briliant clean cooling line and condenser as well. Suction = 5.4 bars. I guess they wanted to run 75% capasity, but with our cooling condition it is impossible, so I planning to drain the freon down to 3.9-4.0(yes 3.6 is perfect one but I want to keep couple of degrees C on evaporator as an insurance to not let if freeze)
@ACRWorldsl that is my question) the condenser doesn't have any drain cock, so I think to manualy open safety valve(of course after freon accumulated in condenser and got cooled). May be there is enother way how to drain the freon from the compressor?
