Features and Benefits

• Two-Stage Scroll Compressor: Provides two speeds (high and low) for cooling and heating, ensuring more precise temperature control, lower humidity, and greater efficiency compared to single-stage compressors.
• 7mm Condenser Copper Coil: Requires less refrigerant, resulting in a smaller and lighter footprint while enhancing reliability.
• Inverted Reversing Valve: Facilitates faster heat transfer with gravity assist shifting and reduced joint stress for increased reliability.
• PlusOne® Expanded Valve Space: Offers 3 in. – 4 in. – 5 in. service valve space, providing a minimum working area of 27 square inches for easier access during maintenance.
• PlusOne® Triple Service Access: Features a 15-inch wide access panel with two fasteners and removable corner and individual louver panels, making repairs faster and easier.
• PlusOne® Refrigerant Detection System™: An integrated, patented system with an A2L sensor and mitigation board for easier commissioning, simplified wiring, and system protection that pauses operation if excess refrigerant is detected.
• Designing for Sustainability with Low GWP: Utilizes R-454B refrigerant, which has a significantly lower Global Warming Potential (GWP) than previous refrigerants, aligning with environmental protection goals and delivering energy-efficient comfort.

General Data and Electrical Specifications

Electrical Data:

Notes: Refrigerant charge is sufficient for 15 ft. of refrigerant lines. For longer line set requirements, consult installation instructions. HACR type circuit breaker or fuse is recommended. Refer to National Electrical Code for wire, fuse, and disconnect size requirements.

Accessories

*Bi-flow kits are required when installing a liquid line solenoid on a heat pump.

Weighted Sound Power Level (dBA)

Note: Tested in accordance with AHRI Standard 270-08.

Clearances

Proper clearances are essential for optimal performance and serviceability. The following minimum clearances are recommended:

• Service Access: 24 inches (609.6 mm)
• Side Clearance: 6 inches (152.4 mm)
• Top Clearance: 12 inches (304.8 mm)
• Front Clearance: 24 inches (609.6 mm) recommended, 6 inches (152.4 mm) minimum.
• Overall Unit Clearance: Allow 60 inches (1524 mm) of clearance around the unit.

Important: When installing multiple units in an alcove, roof well, or partially enclosed area, ensure adequate ventilation to prevent re-circulation of discharge air.

Refrigerant Line Size Information

This section provides detailed guidelines for selecting appropriate refrigerant line sizes based on unit capacity, equivalent length, and maximum vertical separation. These tables are crucial for ensuring optimal system performance and efficiency. They cover various combinations of liquid and suction line sizes for different unit tonnages and equivalent lengths up to 250 feet (76 meters).

Note: Light grey shaded areas in the original tables indicate conditions considered "long line" and may require specific accessories. Consult the Long Line Set Guide for details. Avoid using suction line traps in the suction riser as they can increase pressure drop.
