Features and Beneﬁts

• iQ Drive: Inverter driven Samsung rotary compressor provides ﬁve capacities

in modulating operation from a two stage thermostat.

• Interface control board: Two digit LED provides system operation, status

and diagnostic troubleshooting information. Utilizes a NORDYNE-patented

capacity control algorithm to select the optimum system capacity level.

Internal controls monitor system operation to protect the inverter drive

and compressor.

• Cooling operation temperature range: 50 °F to 125 °F.

• Five Minute Restart Time Delay: keeps the unit from restarting, eliminating

the highest cause for compressor failure.

• EXV control: Precise refrigerant superheat control provided by an electronic

expansion valve.

• Suction Accumulator: Protection from liquid ﬂood back and future

compressor failures.

• Compressor and Component Access: Designed to make servicing easier

for the contractor, hinge access panel is provided to all controls and the

compressor.

• High Efﬁciency with low Sound Levels: 20 SEER with sound ratings from 63

to 74 db depending upon operating conditions. Engineered to signiﬁcantly

reduce unwanted noise with compressor sound blanket, variable speed

condenser motor and swept-wing fan blade and discharge mufﬂer.

• 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: Factory installed.

• Micro-Channel Condenser Coils: All aluminum coils that provide high

corrosion resistance and increased heat transfer.

• Anteater Copper Tube (Luvata Uniguard) / Aluminum Fin Indoor Coils:

Indoor coils are designed to optimize heat transfer, and increase durability

and reliability.

• Wire Guard Coated with Earth Friendly Epoxy and Plastic Mesh Hail

Guard: A guard that will never rust and protects the units coil from being

damaged.

• Designed using galvanized steel: with a polyester urethane coat ﬁnish. The

950 hour salt spray ﬁnish resists corrosion 50% better than comparable

units.

• Heavy-Gauge Full Perimeter Base Rails: Facilitates forklift handling and

curb mounting.

• Convertible Air Delivery: Horizontal or downﬂow to accommodate rooftop

or horizontal applications.

• Corrosion-Resistant Drain Pan: Quickly drains away evaporator condensate.

• One Piece Top for Great Fit and Finish, Total Seal: Well designed, quality

construction. Drip edge on top panels whisks away rainwater. Embossed

bottom pan keeps blower component compartment dry.

• SmartStart

Control Board: Provides extended life to igniters using hot

surface ignition technology. Programmed to learn the heat-up characteristics

of the igniter, then adapt the ignition time to the characteristics of the

furnace so the igniter is energized appropriately.

• Hot Surface igniter: Innovative application of an appliance type igniter

with a 20 year history of reliability.

•EnergyEfcientVariableSpeedECMBlower: Advanced motor

technology provides 16 ﬁeld selectable cooling and 8 for heating. Extra

quiet and smooth blower on and off cycles, automatically adjusts to

different static loads.

The iQ Drive gas/electric

packaged system features

modulating compressor

technology and variable speed

indoor and outdoor fan motors.

This system is controlled from a

two stage cooling and heating

thermostat. The system has the

capability of adding up to 18%

of additional cooling above the

rated capacity. The system has

de-humidiﬁcation capabilities

from a capable thermostat or a

duct mounted humidistat. These

packaged gas/electrics are ultra-

high efﬁcient self-contained

heating and cooling units that

can be installed on the roof or on

a slab. The convertible unit design

makes installations simple in all

applications. Units are ETL and

ETLc listed.
