- Simple installation.
- Single-zone: One outdoor unit connects to one indoor unit to control comfort in a single space.
- Sleek, compact design.
- Up and down swing-mode: The indoor unit can move air up and down throughout the room using horizontal vanes, similar to an oscillating fan.
- Vane settings: Allows for air flow direction control.
Outdoor Unit Features
- Blue Fin Coating: An anti-corrosion treatment applied to the aluminum fins of the heat exchanger to protect against corrosion from salt, sulfur, and other airborne contaminants, especially in coastal and industrial areas.
- Continuous operation: Supports 24-hour continuous operation in cooling mode.
- Fast restart.
- High pressure protection.
- High pressure/temperature protection.
- INVERTER-driven compressor: Generates precise capacity to maintain a set temperature point.
- Low ambient cooling: Provides 100% capacity down to 0°F.
- Pre-charged refrigerant: Units from 12k-30k BTU/h come pre-charged for ease of installation. 24k-30k BTU/h units are pre-charged for a maximum line length of 225 feet. 12k-18k BTU/h units are pre-charged for up to 165 feet of line length. Units 36,000 BTU/h and above may require additional refrigerant charges.
- Seacoast protection: Standard in 2022 production, featuring a robust anti-corrosion system with phosphate and acrylic-enamel coated external panels, epoxy resin-coated fan motor support, separator assembly valve beds, and Blue Fin treatment for the heat exchanger coil. These components are rated for 2,000 hours of durability under ASTM B117 testing standards for longevity in corrosive coastal environments.
- Superior energy and operational efficiency.
