✔ 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.

✅ 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
⚠ Maximum Allowable Length: The total line set length must not exceed 75 feet per zone to maintain system efficiency and performance.
⚠ Handling Excess Cable: If your installation requires less than 75 feet, coil any excess control cable—do not cut it, as this can compromise system integrity.
