back spacing for mini-split outdoor unit
I’m about to install my new concealed duct minisplit (Senville). The wall bracket they sold me does not provide the specified distance from the wall; manual says minimum 30cm/11.8″, whereas if I install it with the bracket as-is, it will be about 10″. This includes an extra 1.5″ I get from mounting the bracket to a ledger board, which in turn is on battens on the wall. By default, the space you’d get on a flat wall would be more like 8″. I called their tech support as was told to just ignore the spec in the manual, that it was more about having access for maintenance than airflow reasons. So I guess my question is, really? Should I just install it with 10″ spacing, or should I use some spacers and extra long bolts to get the unit the specified 11.8″ spacing?
