515.16-TG1Y (1095) Advance Information SPLIT SYSTEM HEAT PUMP 10 S ERA 018 thru 060 1.5 thru 5 NOMINAL TONS DESCRIPTION The ERA series heat pumps are designed for use with a variety of YORK evaporator sections to suit any application need. A full line of matching Add-On Coils are available for use with upflow, downflow or horizontal furnaces. Matching Air Handlers are also available for upflow, downflow or horizontal installation to provide a complete system. Electric heat may be installed in air handlers. All units are factory charged to assure easy installation. FEATURES DURABLE CONSTRUCTION - The outdoor unit is constructed of pre-painted steel that offers tough protection against corrosion and resists fading when exposed to sunlight. Drain holes are incorporated into the base pan to permit free drainage of moisture. QUALITY - The black outdoor coil is constructed of copper tube and aluminum fins for durability. Coil guard provides additional protection when installed in a heavy traffic area. PROTECTED COMPRESSOR - The hermetic compressor is internally protected against high pressure and temperature by the simultaneous operation of a high pressure relief valve and temperature sensors which stop the compressor if operating temperatures go too high. Both protectors reset automatically. TIME TEMPERATURE DEFROST CONTROL - Provides defrost including field selectable time periods between cycles (30, 60, 90 minutes). LOW OPERATING SOUND LEVEL - The compressor is mounted on rubber isolators to reduce operating sounds. The slow moving condenser fan keeps air turbulence and sound to a low level. EASY ACCESS - Removable panel affords accessibility to the electrical box. FACTORY TESTED - to verify system operation and control functioning before shipment. FULLY CHARGED AND FACTORY WIRED - to simplify installation and reduce labor costs. Only power supply and control wiring and refrigerant lines must be connected. All models are sweat connect with re-usable service valves. U.L. AND C.U.L. LISTED - approved for outdoor application. ARI CERTIFIED - to comply with ARI standard 240 and 270 for rating air cooled heat pump units. SINGLE PHASE - one (1) year limited parts warranty to original registered owner. Five (5) year warranty for compressor. FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

Cooling MBH based on 80 F entering air temperature, 50% RH, and rated air flow. includes compressor, outdoor fan and indoor blower motor watts. Add-on coils include 365 watts/1000 for blower motor. (Energy Efficiency Ratio) is the total cooling output in BTU s at a 95 F outdoor ambient divided by the total electric power in watthours at those conditions. S (Seasonal Energy Efficiency Ratio) is the total cooling output in BTU s during a normal annual usage period for cooling divided by the total electric power input in watt-hours during the same period. 1 TXV = Thermal Expansion Valve Kit. Must be used with Hard Start Kit Accessory. 2 To meet Florida R=4.2 insulation code requirements, substitute N1FA, N3FA for N2AH, N4AH, G1FC for G3HC AND F1FP FOR F1RP models. All ratings remain the same. 3 P2MP, P2DP, and P2UR furnaces and F1RP air handlers have B.O.D. standard.
