Hi all.
I've been to a bottle cooler that was reported as not cooling. The unit is marked up as R600a (66grams), but has had an evaporator repair and a line tap valve.
According to bar owner the last guy had a cylinder that was definitely NOT R600. As most of the older types of these coolers used R134a, I think that is what the system has been charged with.
Is this going to be a future problem? Even if I recover what is in there now (for disposal), and recharge with R600a, are there likely to be any long lasting problems? I'm thinking of compressor and oil.....
Thanks
Graham
