I'm sure this has been posted before, but I was curious. What is the main reason the supplier wants you to install a filter drier inside next to the evap coil. Icp zip ties the drier on the condenser outside next to the valves, this seems backwards to me? Why wouldn't they put the drier with the indoor coil? Can't you install the drier next to which ever coil you want but still have the flow going the correct way, and have it still work properly?
