Daikin LS14381230DMSF Flared Lineset 30 Foot Dms

Product Description

The DAIKIN LS14381230DMSF is a pre-flared refrigerant lineset designed for DMS mini split system installations. The set includes three lines: a 1/4-inch liquid line, a 3/8-inch suction line, and a 1/2-inch line, running 30 feet in length. Pre-flared ends eliminate the need for field flaring, reducing installation time and the risk of refrigerant leaks at fittings. Licensed HVAC technicians working on ductless split systems are the primary installers of this lineset.

This lineset is suited for residential and light commercial ductless mini split applications where a 30-foot run between the indoor air handler and outdoor condensing unit is required. The DMS designation indicates compatibility with Daikin DMS series mini split systems. The three-line configuration supports systems requiring a separate liquid line, suction line, and additional refrigerant or communication line. Typical installations involve routing the lineset through walls, ceilings, or line-hide conduit.

Key Features

• Pre-flared ends for leak-resistant connections without field flaring
• 1/4-inch liquid line, 3/8-inch suction line, and 1/2-inch third line in a single set
• 30-foot length suits standard residential and light commercial mini split runs
• DMS-specific configuration for Daikin DMS series ductless systems
• Three-line set simplifies ordering and installation for DMS applications

Compatibility

Designed as an OEM-style lineset for Daikin DMS series mini split systems requiring a three-line flared configuration. Confirm system line diameter and length requirements before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician with EPA Section 608 certification. Power down and disconnect the mini split system completely before connecting or disconnecting any refrigerant lines. Do not over-tighten flare fittings, as this can crack the flare and cause refrigerant leaks. Route the lineset through appropriate conduit or line-hide channel and follow all applicable local mechanical codes.
