FEATURES and BENEFITS

• CoreSense

Compressor Protection : Control module

actively monitors compressor conditions and will shut the

unit down to prevent damage.

• Copeland Scroll UltraTech

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/Orice – 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 Mufer – 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.
