• Superior Coil Protection - A stamped, decorative metal coil guard completely protects the coil from debris and other damaging material.
• Isolated Compressor Compartment - A molded composite bulkhead isolates the compressor and refrigeration components from the rest of the unit, reducing sound and vibration.
• Protected Compressor - The compressor is safeguarded against abnormal pressures and temperatures by an internal pressure relief valve, an internal temperature sensor, and factory high and low pressure system controls.  A factory installed liquid line filter-drier further protects the compressor.
• Environmentally Friendly Refrigerant – The next generation refrigerant R-410A delivers environmentally friendly performance with zero ozone depletion.
• Durable Finish – An automotive quality finish provides the ultimate protection from harmful UV rays and rust creep, ensuring a long-lasting, high quality appearance.  A powder-paint topcoat is applied over a baked-on primer using a galvanized, zinc coated steel base material.  The result is a finish that has been proven in testing to provide 33% greater durability than conventional powder-coat finishes.
• Lower Installed Cost - Designed to provide enhanced installability by featuring a slide-down control compartment that allows easy access to control components, along with angled service valves to reduce overall installation time and cost.
• Low RPM Fan Motor – Helps to reduce airflow noise.
  Low Operating Sound Levels - A fan design boasting technology adapted from aeronautic and defense engineering provides for whisper-quiet operation by allowing air to flow smoothly and efficiently across the fan tips.
• Filter-Drier - A factory installed, solid core liquid line filter-drier removes harmful debris and moisture from the system.
• Easy Service Access - A full end, full service access panel with handle makes for easy entry to internal components.
• Composite Base – The strong and durable composite base pan provides added strength while resisting rust and corrosion, as well as reducing sound and vibration.
• WhisperDrive™ System - Features combination of swept-wing fan, composite base pan, isolated compressor compartment and two-stage compressor to reduce overall sound to a mere whisper.
• Communications Capable – Requiring only a simple 4-wire installation, the communicating capability enables the use of the Touch Screen.
• Communicating Control - allowing real time visibility of system operation and the use of diagnostic features, while still maintaining the ability to function with a traditional thermostat.
