TECHNICAL

SPECIFICATIONS

• 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 signicantly

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.

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%).

FEATURES and BENEFITS

– 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.
