PERFORMANCE DATA CERTIFIED BY:

DESCRIPTION48TC units are single-packaged electric cooling, gas heating units that are pre-wired and pre-charged with Puron® (R-410A)HFC refrigerant. The units are factory tested in both heating and cooling modes. These units meet the DOE-2018 (Departmentof Energy), ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1-2016, andIECC-2015* (International Energy Conservation Code) minimum efficiency requirements. Models with two-stage cooling andtwo-circuit design (08-16 sizes) come standard with two-speed indoor fan motor Stage Air Volume (SAV™) for U.S. installa-tions. Models with two-stage cooling and one-circuit design does not require two-speed fan motor to meet U.S. minimum effi-ciencies for DOE.

FEATURESStandard Base Unit (United States Models)• Two-stage/two-circuit cooling capacity control on 08-16

models• Two-stage/one-circuit cooling capacity control on 08,

09, and 12 models.• Energy Saving Staged Air Volume (SAV™) two-speed

indoor fan motor on two-circuit (08-16). Required inU.S. installations. Not available or required to meetDOE on 48TC*M models 08, 09, and 12.

connections.Standard Base Unit (Non-United States Models)• All features listed above• IEERs:

—up to 11.8 with standard motor—up to 12.8 with two-speed/VFD indoor fan motor

• Two-stage/one-circuit cooling capacity control (sizes 08to 12)

Cabinet (All)• Access panels with easy grip handles and NO-STRIP

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

panels tested to 500 hours salt spray protection• Fully insulated cabinet• Tool-less filter access door

Refrigerant System (All)• Accutrol† and or TXV refrigerant metering system• Liquid line filter drier• Scroll compressors with internal line-break overload

protection• Copper tube, aluminum fin evaporator coils• Top cover removable gauge line plugs for reading

refrigerant pressure with unit panels in place.• Round Tube/Plate Fin (RTPF) condenser coils on all

model sizes or Novation® all aluminum condenser coilsavailable on sizes 08-14 with two-stage/two-circuit.

Gas Heat (All)• IGC solid-state gas heat exchanger control for on-board

diagnostics, anti-cycle protection, LED error code des-ignation, burner control logic and energy saving indoorfan motor delay

• Gas efficiencies up to 82%• Designed in accordance with ANSI Z21.47 (design and

test standard for gas furnaces) and ANSI Z233.1(National Fuel Gas code relating to appliance installa-tion requirements)

• Induced draft combustion• Redundant gas valve, with up to 2 stages of heating• Flame roll-out safety protector• Solid-state electronic direct spark ignition systemStandard Limited Parts Warranty• 15-year limited on all gas heat exchanger parts -

Stainless Steel• 10-year limited on all gas heat exchanger parts -

Aluminized• 5-year limited on all compressor parts• 5-year parts on Factory Installed Ultra Low Leak
