Daikin LS14121230DMSF Dms Flared Lineset 30 in

Product Description

The DAIKIN LS14121230DMSF is a pre-flared refrigerant lineset designed for use with Daikin DMS mini split systems. It consists of insulated copper tubing in a 1/4 inch and 1/2 inch diameter configuration, with 1/2 inch flared connections and an overall length of 30 inches. Pre-flared ends eliminate field flaring, reducing the chance of connection errors during installation. HVAC technicians use this lineset to connect the indoor air handler to the outdoor condensing unit as part of a mini split refrigerant circuit.

This lineset is suited for residential and light commercial mini split installations where the DMS lineset specification is required. The pre-flared fittings are sized for compatibility with Daikin DMS system connection ports. Typical applications include wall-mounted and ceiling cassette mini split systems where a factory-prepared lineset simplifies the refrigerant circuit hookup and reduces labor time on the refrigerant side of the installation.

Key Features

• Pre-flared ends at 1/2 inch diameter for direct connection without field flaring
• Dual-line configuration: 1/4 inch liquid line and 1/2 inch suction line
• 30-inch length suited for short-run or inter-cabinet routing
• Designed to the Daikin DMS lineset specification
• Factory preparation reduces field labor and potential leak points at connections

Compatibility

Designed as a DMS-specification flared lineset for Daikin mini split systems requiring a 1/4 inch by 1/2 inch line configuration with flared connections.

Installation Notes

Installation should be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 requirements. Recover any existing refrigerant charge before disconnecting refrigerant lines, and shut off all power to both the indoor and outdoor units before beginning work. Inspect flare seats on both the lineset and the equipment connections for damage before torquing fittings, and pressure-test the circuit after connection per the equipment manufacturer's commissioning procedure. Do not over-tighten flare fittings, as this can crack the flare seat and cause refrigerant leaks.
