When installing line sets
When installing your MRCOOL system, handle refrigerant lines carefully to ensure optimal performance and prevent damage.
Prepare Components: Ensure all necessary components, including the line set, outdoor condenser unit, and indoor air handler, are ready for installation.
Bending the Copper Lines: Maintain a minimum 4-inch bend radius and use smooth curves instead of sharp angles to protect the lines and ensure proper refrigerant flow.
Avoid Repeated Bending: Bending copper lines more than three times can harden and weaken them, increasing the risk of breakage. Handle with care and minimize adjustments.
Connect Flared Ends: Attach the 1/4" and 3/8" flared ends of the line set to the corresponding ports on the outdoor condenser unit and indoor air handler, ensuring a secure and leak-free connection.
Secure and Protect: Properly secure the line set along its path and protect it from potential damage, ensuring optimal performance and longevity.
Professional Charging: As the line set is not pre-charged, have a certified HVAC professional charge the system with the appropriate refrigerant to meet your specific requirements
For best results, use gradual bends and consult a licensed professional or our support team if needed. MRCOOL DIRECT 615-553-8118
