Anyone else add a cast iron compressor pump? Help?

Anyone added a cast iron compressor pump? What did you do for a disconnect switch feed?


I recently purchased a 3hp Cast iron compressor from harbor freight to replace an alum one. This HF compressor does not have a port to feed the disconnect switch. Not sure what I need to do to hook this up

Jay, are you speaking of the line that goes from the tank check valve fitting over to the unloader valve on the pressure switch?
