Ultra High Efﬁciency Air Conditioner 20 SEER Residential System 2-5 Ton Capacities

The iQ Drive® air conditioner 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 air handler has de- humidiﬁcation capabilities from the thermostat or duct mounted humidistat.

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.

- System Control: Utilizes a NORDYNE patented capacity control algorithm to

select the optimum system capacity level.

- System Protection: Internal controls monitor system operation to protect the

inverter drive and compressor.

- Cooling operating temperature range: 50 °F to 125 °F.

- Five Minute Restart Time Delay: When the unit shuts down, a delay keeps the

unit from restarting, eliminating the highest cause for compressor failure.

• Compressor and Component Access: Designed to make servicing easier for the contractor, hinge access panels are provided to all controls and the compressor.

• High Efﬁciency with the low Sound Levels: 20 SEER with sound ratings of 59-73 depending upon operating conditions.

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

• Variable Speed Condenser Motor and Swept-Wing Fan Blade: A heavy duty brushless DC motor for long lasting reliability and engineered to provide quiet operation. Requires no maintenance and is completely protected from rain and snow.

• 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.

• 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: Included with unit, ﬁeld installed.

• Micro-Channel Coils: All-Aluminum coils are designed to optimize heat transfer,

and increase durability and reliability.

• Louvered Condenser Guard: Durable metal guard protects the coil from yard hazards and extreme weather.

• Composite Base Pan: Absorbs sound and is corrosion resistant. Composite pan is also stronger and lighter than steel.

• Corrosion Resistance: Designed using galvanized steel with a polyester urethane coat ﬁnish. The 950 hour salt spray ﬁnish resists corrosion 50% better than comparable units.

• One Piece Top/Oriﬁce: Designed for maximum airﬂow and quiet operation.

• Removable Top Grille Assembly: Allows ease of service from the top without

disconnecting fan motor leads.
