[JB987]

Thanks for finding relevant Q and A we used to guide our decision to have a back up system on hand Jon. Couldn't find it on Q and A forum... finally saw it on PDF And thanks for reminding others of the importance of flowing T8 and 10. Our back up system was mounted with primary compressor so both were inspected at same time. Still hate the vagaries of language when it comes to rules and interpretation and amazed at how many interpretations people can make from the same statement...
