Standard Features

  • Copeland Ultra-Tech Scroll Compressor: State of the art 2 stage compressor is standard equipment.
  • Quiet Operation and Low Vibration: Swept-wing fan blade combined with custom Venturi condenser fan.
  • Compressor Sound Blanket
  • Wire guard coated with Earth Friendly Epoxy and plastic mesh hail guard: A guard that will never rust and protects the units coil from being damaged.
  • Anteater Evaporator Coil: For increased resistance against formicary corrosion, the number one cause of evaporator coil failures.
  • Designed using Galvanized Steel: With a polyester urethane coat finish. The 950 hour salt spray finish is 1.5 mil thick and resists corrosion 50% better than comparable units.
  • Smaller Panels, Great Fit and Finish, Total Seal: Well-designed, quality construction.
  • One Piece Top Pan: With drip edge on top panels whisks away rainwater.
  • Embossed bottom pan: Keeps blower component compartment dry.
  • Permanently Lubricated Condenser Motor: A heavy duty PSC motor for long lasting reliability and quiet operation. Requires no maintenance and is completely protected from rain and snow.
  • Thermostatic Expansion Valves: Factory installed externally equalized thermostatic expansion valves provides precise refrigerant control under varying load conditions.
  • Hi/Low Pressure Switches: Ensure long compressor life.
  • Externally Accessible, High Flow Service Ports: Quick access to refrigeration system.
  • Liquid Line Filter Driers: Factory installed at a convenient location for service.
  • Suction Accumulator: Protection from liquid flood back and future compressor failures.
  • Low voltage Transformer: Includes 5 Amp fuse to protect low voltage circuit.
  • Corrosion-Resistant Drain Pan: Quickly drains away evaporator condensate.
  • ECM Variable Speed Blower Motor: Advanced technology allows the motor to automatically adjust to different static loads. The variable speed motor allows for extra quiet operation and improved air quality.
  • Demand Defrost Standard: Provides additional energy savings in heating by defrosting only when necessary.
  • Three Minute Restart Time Delay: When the unit shuts down, a three minute delay keeps the unit from restarting, eliminating the highest cause for compressor failure.
  • Heavy-Gauge, Full Perimeter Base Rails: Facilitates forklift handling and curb mounting.
  • Convertible Air Delivery: Horizontal or downflow to accommodate rooftop or horizontal applications.
  • Easy Compressor and Control Access: Designed to make servicing easier for the contractor, access panels are provided to all controls and the compressor from the side of the unit.
  • Removable Top Grille Assembly: Allows ease of service to the fan motor.
  • Duct Flanges: Reduce installation costs.
  • Proven, Industry Standard Components: Easier service and availability.
  • SmartLite™ Control Board: Provides extended life to igniters using hot surface ignition technology. Programmed to learn the heat-up characteristics of the igniter, then adapt the ignition time to the characteristics of the furnace so the igniter is energized appropriately.

Optional Features - Factory Installed

  • 2-Stage Gas Heat Operation: Featuring a 2 stage gas valve and 2 speed inducer motor.
  • Choice of Heating Control: Two stage thermostat or single stage heating thermostat with on the control board timing of 5 or 10 minute delay for second stage of heat.

Optional Features - Field Installed

  • Cap duct adapter
  • Low ambient kit
  • LP conversion kit
  • Universal hard start kit
  • Thermostat with backup gas heat capability (outdoor sensor required)
  • Thermostat - outdoor sensor
  • Skirt trim kit
