I have a Trane Mini split unit with no charging chart. I have tried to get one with no success. Guys, I need to know if these units charge similarly to regular R-22 units. I have charged a Mini-split by Mitsubishi before that acted differently than a regular R22 unit. I think that the liquid line and suction lines both were cold and the pressures were strange, but I charged as specified and she purred like a kitten.
Anyway, please let me know if I should just charge as usual. I know there are no rules of thumb on this site, but we all know what make these things tick and I have a computer server room in need of some backup with this little unit. Thanks
