The 9k 12k & 18k BTU MrCool DIY Ductless Split System Line Set is designed exclusively for use with MrCool DIY ductless mini splits that have a 9k, 12k, or 18k air handler. This line set will not function with any other MrCool products or any existing third-party ductless mini split products. Attempting to use this product with a non-approved system will void warranty protection for both this line set and the non-approved product.

Since it is meant for a do-it-yourself product, the 9k 12k & 18k BTU MrCool DIY Ductless Split System Line Set is user-friendly and easy to install. It comes pre-charged and sealed from the factory with the correct amount of R-410A refrigerant. It features Quick Connect fittings, so that it can plug in easily to both the air handler and the condenser without losing charge or being exposed to environmental contaminants. To make the seal complete, all you need are a few wrenches and a hex key.

The 9k 12k & 18k BTU MrCool DIY Ductless Split System Line Set features a 1/4 inch liquid line and a 1/2 inch suction line. It weighs approximately 10 lbs. It is currently available in 16 and 25 foot increments. Should you need less length for your installation, simply bundle the excess into a loose coil and store it near the condenser.
