Installation Tips for Optimal Performance
Measure & Plan Line Path Before Installation
Confirm the total distance and routing path between indoor and outdoor units to ensure the 35 ft line set and accessories fit without sharp bends or excessive stretching.
Protect Lines at Wall Penetrations
Use the included wall pipe cover to protect copper lines as they pass through walls, preventing insulation damage and ensuring a professional, clean finish.
Secure Lines with Proper Supports
Install clamps, straps, or HVAC mounting brackets along long line runs to reduce vibration, prevent sagging, and protect insulation integrity.
