I am working on a LG Multi V Mini 4 ton condensing unit that is connected to three fan coil units. Today we moved the condensing unit four feet and now the condenser cannot communicate with the fan coil units. We added about 4 feet of com line to the existing line and soldered the tap. I understand that the factory wants me to run a new wire to the first fan coil, but that cannot happen without destructive work to the residence. this is a very expensive home in the Bahamas that we installed one year ago without any issues.

Please I am at the end of my friggen rope, can anyone assist?

Thanks Greatly!
