Hi everybody, I'm new to the forum. I was wondering if anybody new where I can get step by step instructions about how to purge, evacuate and recharge my 5ton RUDD heat pump. I had a line leak, and lost all my freon. I got my EPA cert. to buy freon. I have everything I need to do the job, but I don't want to miss any critical steps. If anyone can help, please let me know.
