@jd's thanks for the advice man, but why not try r32oc for more specific answers to your questions which only you know. Why not try asking a question for us to answer? We may just know it. There are many wise (and old) r32 owners on here. Most of them already know everything they need to so hence why the little amount of questions on thus section. We have 12,000 regular visitors on this site and if you don't ask, you don't get. That is not a constructive post. That doesn't give us advice on what to help you with or how we can be of service. Frankly it's just rude. Please be more constructiv
