This 25 ft. copper line set is designed to link the MRCOOL DIY 5th Generation Condensers to the MRCOOL DIY 5th Generation 9K, 12K & 18K Air Handlers. These line sets are pre-charged with R-454B refrigerant for added convenience. In Multi-Zone systems, it is essential to use one line set for each indoor unit to guarantee optimal system performance.
Please note that this line set includes a 25′ communication wire. If you are acquiring an MRCOOL DIY 5th Generation E Star mini split system that includes an air handler, a 25 communication wire will be included in the air handler packaging.
