INDOOR UNIT FEATURES
• Auto fan speed mode: Automatic adjustment of fan speed
• Easy-to-clean, washable filter
• Filter status indicator
• Ideal PCA Spaces: Ideal for larger retail stores, classrooms, and restaurants
• Knock-out for outside-air intake
• Light commercial: Units with this icon are suitable for light commercial applications such as small offices, restaurants, and retail.
• Multi-Airflow settings: Airflow settings for high and low ceiling applications
• Multiple control options, including the comfort app for remote access, third-party interfaces, and both wired and wireless controllers
• Suspends from ceiling for quick and easy installation
• Up and down swing-mode: An indoor unit with this capability can move air up and down throughout the room like an oscillating fan using the horizontal
vanes.
OUTDOOR UNIT FEATURES
• Blue Fin Coating: An anti-corrosion treatment applied to the aluminum fins of the heat exchanger of the outdoor unit to protect against corrosion caused
by salt, sulfur, and other airborne contaminants, especially in coastal and industrial areas.
• Continuous operation: 24-hour continuous operation (cooling mode)
• Fast restart
• High pressure protection
• INVERTER-driven compressor: An inverter-driven compressor generates the precise capacity needed to maintain a temperature set point.
• Low ambient cooling: Low ambient cooling down to -40°F providing 100% capacity (with wind baffles)
• Pre-charged refrigerant: 12k -30k BTU/h come pre-charged for ease of installation. 24k – 30k BTU/h are pre-charged to maximum line length of 225
feet. 12k – 18k BTU/h are pre-charged for up to 165 feet of line length. For units with a capacity of 36,000 BTU/h and above, additional refrigerant
charges will be required.
• Seacoast protection: Seacoast Protection, made standard in the 2022 production, features a robust anti-corrosion system with phosphate and acrylic-
enamel coated external panels, epoxy resin-coated fan motor support and 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, ensuring longevity in corrosive coastal
environments.
• Superior energy and operational efficiency
