Customer Q&A with Product Specialists
Mark J.
from IN asked:
I need a 50-foot recharged line for a 9,000 BTU MRCOOL unit.
The MRCOOL 50 Foot R-454B Lineset for 18K BTU 5th Gen DIY Series Mini-Splits with Pro Cable is designed for 18,000 BTU units and uses R-454B refrigerant, making it unsuitable for a 9,000 BTU MRCOOL unit.
For a 9,000 BTU MRCOOL system requiring a 50-foot pre-charged lineset compatible with the DIY series, the MRCOOL DIY 5th Gen 50 Ft. Pre-Charged Quick Connect Line Set with DIY Pro Cable (DIY50-1438C-O) is a suitable option. This lineset features 1/4-inch liquid and 3/8-inch suction lines, is pre-charged with R-454B refrigerant, and is compatible with MRCOOL DIY 5th Gen 6K, 9K, and 12K BTU indoor units. Please confirm your unit's refrigerant type before purchasing, as this is specifically for the new refrigerant.
