Daikin LS38783825 Line Set 3/8 X 7/8 X 3/8 25 Foot

Product Description

The DAIKIN LS38783825 is a pre-manufactured refrigerant line set designed for connecting split-system air conditioning and heat pump equipment. It consists of two copper refrigerant lines: a 3/8-inch liquid line and a 7/8-inch suction line, along with a 3/8-inch line, packaged at a 25-foot run length. This line set provides the refrigerant pathway between the indoor evaporator coil and the outdoor condensing unit. Installation is performed by licensed HVAC technicians as part of a new equipment installation or system replacement job.

This line set is suited for residential and light commercial split-system HVAC installations where a 25-foot line run is appropriate for the equipment layout. The 3/8-inch liquid line and 7/8-inch suction line diameters are matched to specific equipment tonnage requirements, making proper equipment-to-line-set sizing verification essential before installation. It is commonly used in new construction and retrofit applications where the indoor and outdoor units are within a standard distance of each other.

Key Features

• 25-foot length accommodates standard residential split-system installation distances
• 3/8-inch liquid line and 7/8-inch suction line configuration for matched system performance
• Pre-cut and pre-formed copper lines reduce field fabrication time
• Designed for refrigerant system use in split-system AC and heat pump applications

Compatibility

Designed as an OEM-style refrigerant line set for split-system air conditioning and heat pump installations requiring 3/8-inch liquid and 7/8-inch suction line diameters at a 25-foot run length.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification for refrigerant handling. Before connecting the line set, ensure the outdoor disconnect and indoor air handler power are fully de-energized. The system must be evacuated to the equipment manufacturer's specified micron level before charging with refrigerant. Follow all local mechanical codes and manufacturer guidelines for line set support, insulation, and flare or braze connection methods.
