The exact communication-wire specification, drain-hose dimensions, wall-sleeve dimensions and accessory quantities should be confirmed for the ordered kit configuration.
99.9% Pure Copper Refrigerant Tubing
The source page specifies 99.9% pure copper for the refrigerant line set. High-purity copper provides thermal conductivity, corrosion resistance and installation flexibility for compatible mini split and heat-pump applications.
ASTM B280 and C12200 Copper Tubing
ASTM B280 and C12200 are referenced in the source product information for the copper tubing. Buyers requiring project documentation should confirm the exact specification supplied with the ordered product.
1/4 in. Liquid Line and 5/8 in. Suction Line
The line set combines a 1/4 in. liquid line with a 5/8 in. suction line. Verify that the selected HVAC equipment specifically requires these exact refrigerant-line diameters before installation.
Pre-Flared Copper Ends with Nuts
The source page states that both ends of the copper tubing are factory pre-flared and supplied with nuts.
Pre-flared connections can reduce field preparation when the flare geometry and nut sizes match the selected indoor and outdoor equipment.
Installers should inspect each flare before connection and tighten flare nuts according to the HVAC equipment manufacturer's specified torque requirements.

Pre-Flared Connection
Black Rubber Insulation
Black Rubber is the primary insulation configuration shown on this page and in the AC installation-kit family table.
The insulation is designed to provide thermal protection, moisture resistance and installation flexibility around the copper refrigerant tubing.
Listed Temperature Range
The source Black Rubber section lists an operating temperature range of approximately -40°C to 120°C. Confirm the applicable range for the exact insulation thickness and configuration ordered.
Moisture and Condensation Protection
The insulation structure helps reduce water-vapor penetration and surface condensation around cold refrigerant piping.
Flexible Insulation Structure
Flexible Black Rubber insulation can make routing easier around compatible HVAC installation paths while maintaining coverage around the copper tubing.
UV-Resistant Configuration
UV-resistant insulation configurations are referenced on the source page. Final outdoor suitability depends on the exact insulation material, thickness and environmental exposure.

Important Checks Before Installation
Confirm Exact Pipe Sizes
Verify that the selected HVAC equipment specifically requires a 1/4 in. liquid line and 5/8 in. suction line.
Verify Permitted Piping Length
Confirm that the equipment manufacturer permits the proposed 35 ft refrigerant piping route.
Check Maximum Elevation Difference
If the indoor and outdoor units are installed at different elevations, verify the manufacturer's maximum permitted vertical separation.
Check Refrigerant Charge Requirements
Confirm whether the 35 ft installation falls within the equipment's factory refrigerant-charge allowance and follow the manufacturer's charging instructions.
Verify Communication Wire Specification
Confirm that the supplied communication wire cable matches the electrical and communication requirements of the selected mini split system.
Plan Condensate Drain Routing
Route the drain hose with suitable slope and follow the indoor-unit manufacturer's condensate drainage requirements.
Installation Guidelines
Inspect the Pre-Flared Connections
Inspect each copper flare before connection and tighten flare nuts according to the HVAC equipment manufacturer's specified torque.
Avoid Sharp Bends and Kinks
Use appropriate HVAC tube-bending methods and suitable bend radii to reduce the risk of tube deformation or restricted refrigerant flow.
Protect the Insulation
Avoid crushing, cutting or leaving unnecessary gaps in the insulation around bends, supports and wall penetrations.
Use the Wall Sleeve at Penetrations
Use the wall sleeve and decorative cover where the line set passes through the building structure to help protect the tubing and insulation.
Pressure Test and Evacuate Before Startup
Refrigerant piping should be leak-tested, evacuated, charged and commissioned according to the HVAC equipment manufacturer's instructions and applicable local requirements.
