This 25 ft. copper line set connects the MRCOOL Condenser to the MR COOL Air Handlers. These Line Sets are Pre-Charged. For Multi-Zone systems, one line set per indoor unit is required to ensure the system will function properly.

This lineset does NOT come with communication wire. However, if you are purchasing a MRCOOL DIY system with an Air Handler, a 25′ communication wire is included in the Air Handler box.
