Friedrich T42250 Insulated Refrigeration Line Set

Product Description

The FRIEDRICH T42250 is an insulated refrigeration line set designed for use with Friedrich 18,000 BTU ductless mini-split indoor units. The line set is constructed from copper and provides the refrigerant pathway between the indoor air handler and the outdoor condensing unit. Pre-insulated copper line sets reduce heat gain and condensation on suction lines, helping the system maintain proper refrigerant state throughout the circuit. Installation is performed by a licensed HVAC technician as part of a ductless system commissioning or replacement service. At 15 pounds, the set is manageable for a single technician during rough-in work.

This line set is intended for residential and light commercial ductless split applications where an 18,000 BTU Friedrich indoor unit is being installed or serviced. It is packaged as a single unit and is sold individually. The copper construction is compatible with standard refrigerants used in Friedrich ductless systems. The package dimensions of 34 inches height, 45 inches depth, and 34 inches width reflect the coiled or bundled form factor as shipped, which is typical for pre-insulated line set assemblies intended for field routing and bending to fit the installation layout.

Key Features

• Matched to Friedrich 18,000 BTU ductless indoor unit applications
• Single-piece set simplifies procurement for new installs and replacements
• Package weight of 15 pounds supports single-technician handling during installation

Compatibility

Designed for use with Friedrich 18,000 BTU ductless indoor units as specified by the manufacturer.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with applicable mechanical codes and the equipment manufacturer guidelines. Recover and reclaim any residual refrigerant from an existing system before disconnecting line sets, per EPA Section 608 requirements. Route and bend the copper lines carefully to avoid kinking, which can restrict refrigerant flow and reduce system performance. Verify all flare or braze connections are leak-free before recharging the system.
