FT4BI Series
R-410A, Ultra High Efficiency Heat Pump, 21+ SEER, 12.5+ EER,
9.6 HSPF Residential System 2-3-4 Ton Capacities
The iQ Drive® Heat Pump System features fully variable speed compressor technology and variable speed indoor and outdoor motors. The system provides variable cooling capacity as needed. It operates near the nominal rated capacity at the thermostat set point and modulates as temperature difference between set point and room temperature changes. The system may run at additional 18% capacity to provide rapid cooling. The system has a built-in humidity control that will activate humidier equipment (if supplied), and reduces blower speed if indoor relative humidity is greater than set point (default set at 60%).
WARRANTY
FEATURES and BENEFITS
• iQ Drive: Inverter driven Panasonic rotary compressor which provides fully variable operation.
• R-410A Refrigerant: Environmentally friendly non- ozone depleting refrigerant.
• Designed using galvanized steel: with a polyester urethane coat nish. The 950 hour salt spray nish resists corrosion 50% better than comparable units.
• Copper Tube / Aluminum Fin Coils: Both indoor and outdoor coils are designed to optimize heat transfer, minimize size and cost, and increase durability and reliability.
• Permanently Lubricated Motor: A heavy duty brushless motor for long lasting reliability and quiet operation. Requires no maintenance and is completely protected from rain and snow.
• Compressor Sound Blanket: Engineered to signicantly reduce unwanted compressor noise.
• Swept-Wing Fan Blade: Engineered to provide quiet operation. The specic energy absorbing hub is designed to reduce noise while operating through various frequencies.
• Louvered Condenser Guard: Durable metal guard protects the coil from yard hazards and extreme weather.
• Removable Top Grille Assembly: Allows ease of service from the top without disconnecting fan motor leads.
• High Pressure Switch: Protects against abnormally high system pressures. Auto-reset feature prevents nuisance service visits.
• Low Pressure Switch: Protects against loss of system refrigerant charge.
• Liquid Line Filter Drier: Included with unit, eld installed.
• One Piece Top/Orifice: Designed for maximum airow and quiet operation.
• 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.
• Highest Efficiency with the lowest Sound Levels: Up to 22 SEER with sound ratings of 59-72dB depending upon operating conditions.
– This product offers a 10-year all-parts warranty. – This product offers a 10 year Quality Pledge to replace
the entire unit, if the unit’s major component (heat exchanger or compressor) fails within the rst 10 years of operation, to the original owner. All split system products must be installed with a matched indoor air handler or indoor coil to qualify.
– Consumer product registration required for both 10
year All Parts Warranty and Quality Pledge within a limited period of time after the installation. See current warranty document or visit our consumer web for warranty details.
