OUTDOOR UNIT FEATURES
• 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
• 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.
