PERFORMANCE DATA CERTIFIED BY:

DESCRIPTION50JC units are ultra high-efficiency single-packaged variable speed electric cooling, electric heating units that are pre-wiredand pre-charged with Puron® (R-410A) HFC refrigerant. Electric heat is available as a field-installed accessory. The units arefactory tested in the cooling mode. All size 04-06 models use variable speed cooling capacity control.

FEATURESStandard Base Unit• Puron (R-410A) HFC refrigerant• SEERs up to 20.0• Exceeds ASHRAE (American Society of Heating,

Refrigerating, and Air-Conditioning Engineers) 90.1-2016 and IECC* (International Energy Conservation Code) IECC-2015 minimum efficiency requirements

• Rated in accordance with AHRI Standards 210/240• Designed in accordance with Underwriters Laboratories

Std 1995 and listed by UL and UL-Canada• Corrosive resistant composite sloping design; side or

center drain condensate pan. Meets ASHRAE Standard 62

• Cooling operating range from 0°F (-18°C) up to 125°F (52°C)

• Field convertible from vertical to horizontal airflow for slab mounting — no special kits required

• Two-inch disposable return air filters.• Thru-the-bottom power entry capability• Single point two-stage electric connections• 24-volt control circuit protected with resettable circuit

breaker• Direct Drive — EcoBlue™ Technology Indoor fan sys-

tem uses Vane Axial fan design and electronically com-mutated motor

– Shall have inherent automatic-reset thermal overloadprotection

– Shall require no fan/motor belts for operation, adjust-ments, and/or initial fan speed setup.

– Shall be internally protected from electrical phase reversaland loss

– Shall have slow ramp up to speed control capabilities tohelp reduce sound and comfort issues

– Shall be a slide-out design with two screw removal• All sizes have variable speed cooling capacity control

that ranges from 25% up to 105% of normal unit capac-ity

• Totally enclosed variable speed condenser motors with permanently lubricated bearings

• Low-pressure and high-pressure switches• Full perimeter base rail with built-in rigging adapters

and fork truck slotsSystemVu™ controls are standard on each unit to helpfacilitate units' diagnostics, ease of commissioning, controlthe cooling, heating, ventilation operation and much more.Some highlights: • Large full text - multi line display• SB Flash Port for data transfer• Built in i-Vu®, CCN and BACnet†

• Built in electrical phase and compressor reverse rotation protection

• Read refrigerant pressure from display- no gauges required

• Quick LED Status - Run, Alert, Fault• Conventional thermostat or sensor capabilities• Historical component runtime and starts• Supply Air Tempering and Demand Limiting control• Equipment / System Touch Compatibility• Supports linkage on zoning systems using CCN VVT

and i-Vu Open VVT controlsCabinet• Access panels with easy grip handles and NO-STRIP

screw collar• Pre-painted exterior panels and primer-coated interior

panels tested to 500 hours salt spray protection• Tool-less filter access door• Cabinet insulated with foil faced insulation that is

encapsulated/taped throughout the indoor air streamRefrigerant System• TXV refrigerant metering device• Liquid line filter drier• Scroll compressors with internal line-break overload

protection• Copper tube, aluminum fin coils with optional corrosion

resistant coils.• Removable gage line plugs for reading refrigerant pres-

sure with unit panels in placeStandard Limited Parts Warranty• 5-year electric heater parts (field-installed)• 5-year compressor parts• 5-year Ultra Low Leak economizer parts (factory-

installed)• 3-year SystemVu™ controls• 1-year parts
