FS4BF-K(B,C) Series

Extra High Efciency Air Conditioner
16 SEER Residential System
2 - 5 Ton Capacity

The FS4BF-K(B,C) Series air conditioners
offers exceptional performance. The unit, when
combined with our engineered coils or air
handlers, offers a line of quality, 16 SEER split system
cooling equipment.

FEATURES and BENEFITS

• CoreSenseTM Compressor Protection : Control module

actively monitors compressor conditions and will shut the
unit down to prevent damage.

• Copeland Scroll UltraTechTM Compressor: The Ultra

Tech Compressor operates with 2 stages of cooling
capacity 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.

• Compressor Sound Blanket: Engineered to significantly
reduce unwanted compressor noise.

• Swept-Wing Fan Blade: Designed to significantly reduce
unwanted noise.

• 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.

• 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/Orice: Designed for maximum airflow
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.

• Micro-Channel: All aluminum coils in all models which
provides high corrosion resistance.

(1) Operating Voltage Range: 187v min. - 253v max.
(2) HACR Type Circuit Breakers may be used.
(3) Requires 1-1/8” to 7/8” reducer from line to unit.
(4) Use of a 3/4” linset 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.
c) 1 1/8” = 0.8 oz. per additional foot.
