So I picked up an r50 mini for my 13 year old son for nothing and I need 914world quality information to get it all perfect. I am used to very small communities... There are so many mini groups... Anyone know of a group that's as useful as 914world? Tall order, I know.

Modern condensers are not flushable or repairable.
The aluminum has gotten so thin as to definitely have a finite lifespan. 15 years ago, I didn't see fatigue failures in condensers or lines. Now, they just flat wear out... Most aftermarket condensers have 30% fewer cooling tubes. I try to go OEM if I can, and the cost is not ridiculous. One benefit to most new condensers is they house the drier package. Moments after line connection I pull a vacuum. Don't pull the plugs on the new condenser until you're ready to connect. The new condenser should be pressurized slightly with nitrogen. Exposing the new drier to ambient humidity will destroy it in 6 hours. Exposing the PAG oil in the system to ambient humidity is BAD as well. For a condenser replacement I wopuld normally add 1.5 ounces of PAG46 oil;. |
