Efficient operation High--efficiency design with SEERs (Seasonal Energy Efficiency Ratio) of up to 13.5. Puron Environmentally Sound Refrigerant is Carrier’s unique refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron refrigerant is in service in millions of systems, proving highly reliable, environmentally sound performance. Easy Installation Factory--assembled package is a compact, fully self--contained, heat pump unit that is prewired, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard capacity ranges with voltage options to meet residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications. Innovative Unit Base Design On the inside a high--tech composite material will not rust and incorporates a sloped drain pan which improves drainage and helps inhibit mold, algae and bacterial growth. On the outside metal base rails provide added stability as well as easier handling and rigging. Durable, dependable components Compressors are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection. ECM Motor is standard on all 50EZ--A models. Direct--drive, PSC (Permanent Split Capacitor) condenser--fan motors are designed to help reduce energy consumption and provide for cooling operation down to 40_F (4.4_C) outdoor temperature. MotormasterR II low ambient kit is available as a field installed accessory. Thermostat controls designed to work as a system with Carrier’s small packaged product. Thermostatic Expansion Valve -- A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency. Refrigerant system is designed to provide dependability. Liquid filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier. High and Low Pressure Switches provide added reliability for the compressor. Indoor and Outdoor coils are computer--designed for optimum heat transfer and efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit. Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 74dBA. Easy to service cabinets provide easy 3--panel accessibility to serviceable components during maintenance and installation. The base with integrated drain pan provides easy ground level installation with a mounting pad. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy. Convertible duct configuration Unit is designed for use in either downflow or horizontal applications. Each unit is converted from horizontal to downflow and includes two horizontal duct covers. Downflow operation is provided in the field to allow vertical ductwork connections. The basepan seals on the bottom openings to ensure a positive seal in the vertical airflow mode. 1 Cabinets are constructed of heavyduty, phosphated, zinc--coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator and electric heater compartments are insulated with cleanable semi--rigid insulation board, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped drain pan minimizes standing water in the drain. An external drain is provided. Short--Cycling protection for the compressor is incorporated into our defrost control board ensuring a five minute delay (+/--2 minutes) before restarting compressor after shutdown for any reason.

(51 mm) condensate trap must be field supplied. Ductwork — Secure downflow discharge ductwork to roof curb. For horizontal discharge applications, attach ductwork to unit with flanges. To convert a unit to downflow discharge — Units are equipped with factory--installed inserts in the downflow openings. Removal of the inserts is similar to removing an electrical knock--out. Units installed in horizontal discharge orientation do not require duct covers. Maximum cooling airflow — To minimize the possibility of condensate blow--off from the evaporator, airflow through the units should not exceed 450 cfm per ton. Minimum cooling airflow — Minimum cooling airflow is 350 cfm per ton in cooling mode. Airflow can be lower in certain modes when humidity removal is an issue. Minimum ambient cooling operation temperature — All standard units have a minimum ambient cooling operating temperature of 40_F (4.4_C). With accessory low ambient temperature kit, units can operate at temperatures down to 0_F (17.8_C). Maximum operating outdoor air temperature for cooling is 125_F (51.7_C).

On units with crankcase heater, heater is also energized. Cooling — With the thermostat in the cooling position, the thermostat makes circuit “R” to “O”. This energizes the reversing valve solenoid (RVS) and places the unit in standby condition for cooling. As the space temperature rises, the thermostat closes circuit “R” to “Y”. A circuit is made to contactor (C), starting the compressor (COMP) and outdoor--fan motor (OFM). Circuit “R” to “G” is made at the same time and starts the indoor--fan motor (IFM). When the thermostat is satisfied, contacts open, deenergizing C. The COMP and OFM stop, and the IFM stops after the preselected time delay. On the loss of the thermostat call for cooling, 24 V is removed from both the “Y1/Y” and “G” terminals (provided the fan switch is in the “AUTO” position) de--energizing the compressor contactor and opening the contacts supplying power to compressor/OFM. After a 90--second delay, the IFM shuts off. If the thermostat fan selector switch is in the “ON” position, the IFM will run continuously. Heating — On a call for heat, thermostat makes circuits “R” to “Y) and “R” to “G”. A circuit is made to C, starting COMP and OFM. Circuit “R” to “G” also is completed, energizing IFR and starting IFM after the selected time delay. Should room temperature continue to fall, circuit “R” to “W” is made through second--stage thermostat. If optional electric heat package is used, a relay is energized, bringing on first bank of supplemental electric heat. When thermostat is satisfied, contacts open, deenergizing contactor and relay; motors and heaters deenergize. Defrost — Defrost board (DB) is a time and temperature control, which includes a field--selectable time period (dip switch 1 and 2 on the board) between checks for defrost (30, 60, 90, or 120 minutes). Electronic timer and defrost cycle start only when contactor is energized and defrost thermostat (DFT) is closed. The defrost board is also equipped with a third dip switch for selecting Quiet Shift operation. The Quiet Shift operation turns compressor off at defrost initiation and termination. Unit is factory shipped with quiet shift turned off. Defrost mode is identical to cooling mode, except outdoor fan motor stops and a bank of optional electric heat turns on to warm air supplying the conditioned space. NOTE: 1. Compressor time delay occurs through the defrost control board. 2. Defrost control board has built in 5 minute compressor delay; once the compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed. 34 Packaged Heat Pumps HVAC Guide Specifications Size Range: 2 to 5 Tons, Nominal Cooling Carrier Model Number: 50EZ--A Part 1General SYSTEM DESCRIPTION Outdoor, packaged, air--to--air heat pump unit utilizing a hermetic scroll compressor for cooling duty and optional electric heating.
