Features/Benefits (cont)All units are designed with a singlecontinuous top piece to eliminateany possible leaking at the seamsor gasketing, which tends to deter-iorate over time and shift duringrigging procedures.Low-voltage wiring connectionsare easily made due to the termi-nal board which is convenientlylocated for quick simple access.Field-installed accessory electricheaters are available in a wide rangeof capacities. Single-point wiring kitmakes installation simple.Downflow-only option is shippedfrom factory for vertical ductwork con-nection and requires no conversion.Optional base rail provides holesfor rigging and forklifts as well asan elevated mounting frame that givesadditional structural support to hori-zontal installations.ServiceabilityStandardized components arefound in all safety devices, outdoor-fanmotors, and control boards. Thisallows for greater inventory control,familiarity, and fewer stocked parts.Easily accessible refrigerantaccess ports on all discharge, suc-tion, and liquid lines permit easy andaccurate measurements.Model number nomenclatureARI* capacitiesCOOLING AND HEATING CAPACITIES AND EFFICIENCIESUNIT50HX NOMINALTONS STANDARDCFMNET COOLING†CAPACITIESAT 95 F (Btuh) SEER†NET HEATING†CAPACITIESAt 47 F (Btuh)COP†At 47 F(Btuh)NET HEATING†CAPACITIESAt 17 F(Btuh)COP†At 17 F(Btuh) HSPFSOUNDRATINGS**(Bels)024 2 800 23,400 12.0 23,800 3.2 12,400 1.8 6.9 7.8030 2 1 ⁄2 1000 28,600 12.0 28,200 3.2 15,400 1.9 7.1 7.8036 3 1200 35,000 12.0 33,000 3.2 18,000 1.9 7.0 8.0042 31 ⁄2 1400 41,500 12.0 40,000 3.3 21,000 1.9 7.0 8.0048 4 1600 47,500 12.0 44,000 3.5 23,600 2.0 7.0 8.2060 5 1800 57,000 11.0 57,000 3.5 31,800 2.0 7.2 8.2LEGENDBels — Sound Levels (1 bel = 10 decibels)COP — Coefficient of PerformanceDOE — Department of EnergyHSPF — Heating Seasonal Performance FactorSEER — Seasonal Energy Efficiency Ratio*Air Conditioning & Refrigeration Institute.†Rated in accordance with ARI Standard 210/240, latest revision and/or U.S. Government DOE test procedures.**Rated in accordance with ARI Standard 270, latest revision.3
