I need to change oil in compressor. Is there anyway to find correct amount of oil. It is one of the large r-502 compressor. Part # is 048259 Taylor parts list Bristol as compressor brand.

hi jim, you need to reclaim the gas, possibly disconect the compressor pour out the oil into a container messure the amount of oil you have taken as an indicationof how much oil is requiered, check with the wholesaler the correct type of oil and the amount requiered < and seal the fridge system whilst you are ready to carry on the job< reconnect the compressor, fit new dryer, pressure test with ofn, whilst vaccing out, suck the oil in, weigh in new gas, run on test, leak test, ok
just a question ? why do you want to change the oil?

[jimsfaust]

System has had leak repair and am changing from R502 to R404. Have new dryer to replace after I flush system and change oil.

Hi jimsfaust,


Have new dryer to replace after I flush system

What are you using to flush the system?

Just interested.

I also wanted to know how did you flush the system... have you cleaned it or just flushed?

[jimsfaust]

R11x flush

[Fri3Oil System]

Isn't it forbidden in the US? Here it is... here companies clean the circuits properly, without releasing any gas to the atmosphere

[jimsfaust]

R11x is a solvent not a refrigerant. It is not R11

[Fri3Oil System]

Ok, I got it now, didnt read the "x"... Anyway, if you used a solvent, you may still have some of that solvent on that circuit. It's better to use the same refrigerant of the installation in order to extract all acids, oils, water, or whatever.
With this method, you can recycle the refrigerant you are using on site, and reuse it afterwards- (not in this case that your are retrofitting the plant, of course)
