Installation Tips for Best Results
Plan Your Line Route Carefully
Before installation, measure the total distance and plot the routing to avoid sharp bends that might constrain refrigerant flow or damage insulation.
Protect Tubing at Wall Penetrations
Use wall sleeves or grommets where the tubing passes through walls to prevent insulation abrasion and ensure a neat finish.
Support Long Runs With Proper Clamps
Use HVAC line clamps or brackets to secure the pipe along its length, minimizing vibration and maintaining insulation integrity.
