PRODUCT DESCRIPTION

MRCOOL 50' Line Set Extension Kit – Extend Your DIY Mini Split System Up to 75 Feet

When your MRCOOL DIY Mini Split System requires installation beyond the standard 25-foot line set, the MRCOOL 50' Line Set Extension Kit provides the perfect hassle-free solution. This kit extends your system’s reach up to 75 feet, ensuring a secure, efficient, and seamless connection between your indoor air handler and outdoor condenser.

Designed for easy installation, this kit includes a 50-foot pre-charged line set, couplers, and an extended 75' MC5 Pro control cable, allowing for a straightforward extension without the need for vacuuming or refrigerant handling.

✔ Key Features & Benefits

50' Pre-Charged Line Set – Adds an additional 50 feet to your current setup, extending the standard 25-foot line set to a total of 75 feet.
No-Vac® Quick Connect Couplers – Includes DIYCOUPLER-38 and DIYCOUPLER-58, ensuring a secure, leak-proof connection between your existing 25' line set and the new extension.
75' MC5 Pro Control Cable – Replaces the standard 25-foot pre-installed cable, providing a continuous power and communication connection between the indoor and outdoor units.
DIY-Friendly Installation – No cutting, brazing, or vacuuming required—simply connect the line sets using the provided couplers and install the pre-measured control cable.
Optimized for Long-Distance Installations – Designed for MRCOOL DIY Mini Split Systems, ensuring reliable performance and efficiency even at extended distances.

✔ Installation Process

1️⃣ Remove the Pre-Attached Cable – Disconnect the existing 25-foot cable from your indoor unit.
2️⃣ Install the 75' MC5 Pro Cable – Replace the shorter cable with the extended 75-foot cable for uninterrupted power and communication.
3️⃣ Connect the Line Sets – Use the included DIYCOUPLER-38 and DIYCOUPLER-58 to securely attach the 50-foot extension to your existing 25-foot line set, bringing the total length to 75 feet.

✔ Important Considerations
