IAQ equipment supported: Customers can add sections with sorbent ventilation technology (SVT) and/or IAQ features to Rebel Applied. Integrated SVT filters adsorb CO2, volatile organic compounds, and other contaminants. When applied in combination with ASHRAE’s IAQ procedure, SVT safely cleans indoor air and also reduces outside ventilation by up to 80%. UV lights and photocatalytic oxidation panels (PCOs) are used in the IAQ section to kill or capture bacteria in the airstream.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Does not share replacement parts with other models.

Additional features: Rebel Applied transforms rooftop systems with high-performance inverter compressors, configurable cabinetry, and IAQ features. Inverter compressors provide precise temperature and humidity control with class-leading part-load efficiencies that meet and exceed most rebate thresholds. Ultra-low-leakage thermally broken cabinetry saves operating costs and provides application flexibility by reducing the equipment footprint up to 37% over legacy models and eliminating transition curbs. Cabinet configurability also provides the space to add IAQ features in a single packaged solution.

Warranty information: One-year standard warranty with optional extended warranties on compressor, parts, fans, gas heat exchanger, and labor.

Special installation requirements: Units must be lifted onto the roof and spreader bars used to allow proper weight distribution. See the installation, operation, and maintenance (IOM) manual for proper lift requirements.
