Westinghouse 16 SEER, 9 HSPF FT4BF Technical Literature
TECHNICAL
SPECIFICATIONS
FT4BF-KA/B Series
Extra High Efciency Heat Pump
16 SEER Residential System
2 - 5 Ton Capacity
The FT4BF-KA/B Series of heat pumps offers
exceptional performance as well as environmental
protection. These models, when matched with
our variable speed air handlers or variable speed
equipped gas furnaces, offer a line of high quality heat
pump systems rated up to 16 SEER and 9.0 HSPF.
FEATURES and BENEFITS
• CoreSenseTM Compressor Protection : Control module
actively monitors compressor conditions and will shut the
unit down to prevent damage.
• Copeland Scroll UltraTech
Tech Compressor operates with 2 stages of heating and
cooling capacities to provide superior comfort and
efficiency. Copeland's proven and simple design equates
to years of comfort and reliability for the homeowner with
virtually silent operation.
• Durable, Attractive Cabinet – Designed using
galvanized steel with a polyester urethane finish. The 950
hour salt spray finish is 1.5 mil thick and resists corrosion
50% better than comparable units.
• Composite Base Pan – Absorbs sound and is corrosion
resistant. Composite is also stronger and lighter than steel.
• 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.
• Demand Defrost – Provides additional energy savings in
heating by defrosting only when necessary
• 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.
• Compressor Sound Blanket – Engineered to significantly
reduce unwanted compressor noise.
• Swept-Wing Fan Blade – Designed to significantly reduce
unwanted noise.
• Low Pressure Switch – Loss of charge protection ensures
long compressor life. Auto-reset feature prevents nuisance
service visits.
• High Pressure Switch – Protects against abnormally high
system pressures. Auto-reset feature prevents nuisance
service visits.
• Liquid Line Filter Drier – Included with unit, field installed.
• One Piece Top/Orice – Designed for maximum airflow and
quiet operation.
• Common Suction Service Port – This port allows the
contractor to read the suction pressure in all modes of
operation without removing any panels, saving time and
increasing serviceability.
• 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.
• Suction Accumulator – Protection from liquid flood back
and future compressor failures.
• Hot Gas Mufer – Reduces compressor noise and
vibration.
• 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.

(1) Operating voltage range: 187V minimum - 253 V maximum.
(2) HACR type circuit breakers may be used.
(3) Requires 1-1/8 to 7/8" reducer from unit to lineset.
(4) Use of a 3/4" lineset will result in approximately 2% loss in capacity.
(5) Additional charge for line sets above 15 feet. Values based on suction line as follows with 3/8” liquid line.
a) 3/4” = 0.6 oz per additional foot.
b) 7/8” = 0.7 oz per additional foot.
