ECHELONTM
SERIES
SPLIT SYSTEM
AIR CONDITIONERS
DESCRIPTION
The Echelon™ Series AC21 variable capacity air conditioners are the outdoor section of a high efficiency communicating cooling system. They are designed as part of a matched system using an AVV air handler or variable speed communicating furnace with a CM coil. Both the matched CM coil and AVV air handler have factory mounted EEVs. The CM coils with factory mounted EEVs can also be matched with the variable speed MVC modular air handlers.

• Superior Coil Protection – An easily removable two-piece steel extruded louver coil guard protects the tube-in-fin coil from debris and physical damage while making access for coil cleaning quick and simple.
• Environmentally Friendly Refrigerant – The next generation refrigerant R-410A delivers environmentally friendly performance with zero ozone depletion.
• Durable Finish – A high quality powder paint finish rated at 1000 hrs. salt spray provides the ultimate protection from corrosion and harmful UV rays, ensuring a long-lasting, high quality appearance.
• Charge View™ – A built-in touch screen instantly displays the system overall condition, including the system pressures and refrigerant charge without the need to attach additional gauges or sensors.
• WhisperDrive™ System – Features a combination of engineered, sound-neutralizing attributes such as a swept-wing fan blade, composite base pan, multi-density compressor cloak and variable capacity operation to reduce sound levels to that of a mere conversation.
• ECM Fan Motor – Dynamically adjusts speed in sync with the compressor demand to keep heat exchange in balance while minimizing power consumption and sound.
• Swept Wing Fan – A design adapted from aerospace engineering provides whisper-quiet operation by allowing air to flow smoothly and efficiently across the fan surface and edges.
• Composite Base Pan – The strong and durable composite base pan is corrosion resistant while adding strength, absorbing sound, and reducing vibration.
• High-Efficiency Outdoor Coil – An aluminum fin and copper tube outdoor coil provide easy cleaning, low restriction to airflow and efficient heat exchange.
• Factory Installed Filter Drier – The liquid line filter drier removes debris and moisture which can be harmful to the system.
• Climate Connect™ – provides pre-configured operating profiles the installing contractor can select during set-up to fine tune the system’s operation for either Humid, Dry, or Normal climates. Additional fine-tune adjustments are always available to provide a custom comfort solution.
• Easy Service Access – A large electrical box cover, independent Charge View access, and a swing open electrical box provide superior full corner access to the inside of the unit for maintenance or service.
• System Protection – Each system contains high and low pressure transducers which constantly monitor system performance and can alert the consumer or contractor system concerns or alerts.
• EEV Controls – All indoor coils, whether in the cased CM coil or in the AVV air handler, have factory installed EEVs (Electronic Expansion Valves).
• Communications Capable – Requiring only 3 thermostat wires between the outdoor and indoor units, the communicating system provides self-commissioning on start-up as well as the ability to check system status at the outdoor unit, thermostat, or remotely using the designated App.
• Variable Capacity Inverter Controlled Scroll Compressor – Constantly monitors and dynamically adjusts system capacity in precise increments as necessary to closely meet the comfort demands of the conditioned space.
• Advanced System Control – The proprietary wi-fi Hx™ thermostat interface is an integral part of this innovative system design. Using the Consumer App, consumers can monitor and adjust their system from anywhere in the world using a smart device. Contractors can use the Service App (with homeowner permission), to monitor the system remotely and make adjustments as needed. The system can be configured to provide alerts for emerging issues as well as items that require immediate attention.
• Premium System Warranty* – Limited lifetime compressor warranty when registered online within 90 days of installation.
• Agency Listed – Safety certified by CSA to UL 1995 / CSA 22.2. Performance certified to ANSI/AHRI Standard 210/240 in accordance with the Unitary Small Equipment certification program.
