Westinghouse 16 SEER, 9 HSPF FT4BF Manuel Technique

 Compressor Protection : Control module 

actively monitors compressor conditions and will shut the 

unit down to prevent damage.

Compressor – The Ultra 

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/Orifice – 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 Muffler – 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.

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.
