Setup, Compatibility & Care
To ensure a successful installation, confirm that your mini-split unit requires a 1/4 inch (6.35 mm) high-pressure line and a 3/8 inch (9.53 mm) low-pressure line. When handling the lines, avoid sharp bends or kinks that could compromise the integrity of the copper tubing.
- Measure the distance between your indoor and outdoor units carefully to ensure the 16-foot length is sufficient.
- Ensure all flare connections are tightened according to manufacturer torque specifications to prevent refrigerant leaks.
- Keep the ends of the lines sealed until the final connection point to prevent debris or moisture from entering the refrigerant circuit.
- Periodically inspect the exterior insulation during routine HVAC maintenance for signs of degradation or physical damage.
