Description

Single--Packaged Products with Energy--Saving Features and Puron refrigerant.• 14.0 to 14.3 SEER • Up to 80.4% AFUE • Factory--Installed TXV• Multi--Speed Blower--Standard • Direct Spark Ignition • Low Sound Levels FEATURES/BENEFITSOne--piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance. 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. The most important advantage of Puron refrigerant is that it has not been banned in future air conditioning systems as the traditional refrigerant R--22 has been. Puron refrigerant is in service in over 100,000 systems proving highly reliable, environmentally sound performance. Easy Installation Factory--assembled package is a compact, fully self--contained, combination gas heating/electric cooling unit that is prewired, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard and optional heating/ cooling size combinations 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. Convertible duct configuration Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow with the two standard duct covers. Efficient operation High--efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of 14.0 to 14.3, 12.0 EER, and AFUE (Annual Fuel Utilization Efficiency) ratings as high as 80.4%. Energy--saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. Standard units are furnished with natural gas controls. A low--cost field installed kit for propane conversion is available for all units. 48VLN units are dedicated Low NOx units designed for California installations. These models meet the California maximum oxides of nitrogen (NOx) emissions requirement of 40 nanograms/joule or less as shipped from the factory and MUST be installed in California Air Quality Management Districts where a Low NOx rule exists. Low NOx option is available on single phase models only. 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. Monoport inshot burners produce precise air--to--gas mixture, which provides for clean and efficient combustion. The large monoport on the inshot (or injection type) burners seldom, if ever, requires cleaning. All gas furnace components are accessible in one compartment. Turbo--tubular heat exchangers are constructed of aluminized steel for corrosion resistance and optimum heat transfer for improved efficiency. The tubular design permits hot gases to make multiple passes across the path of the supply air. In addition, dimples located on the heat exchanger walls force the hot gases to stay in close contact with the walls, improving heat transfer. Direct--drive brushless DC blower motor is standard on all 48VL models. Direct--drive PSC condenser--fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40_F (4.4_C) outdoor temperature. Motormasterr II low ambient kit is available as a field--installed accessory. Thermostat controls Time Guardr II anti--short cycle protection circuitry. If a non--corporate thermostat without anti--short cycle protection is used the Time Guard II field--installed anti--short cycle kit is recommended. 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. Copper fin coils and pre--coated fin coils are available from the factory by special order. These coils are recommended in applications where aluminum fins are likely to be damaged due to corrosion. They are ideal for seacoast applications. Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA. Easy to service cabinets provide easy single--panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with or without a mounting pad. Convenient handholds are provided to manipulate the unit on the jobsite. 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. Standard metal duct covers with insulation come with the unit and cover the horizontal duct openings. These can be left in place if the units are converted to downflow. Integrated Gas Control (IGC) board provides safe and efficient control of heating and simplifies trouble--shooting through its built--in diagnostic function. Cabinets are constructed of heavyduty, phosphated, zinc--coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator/heat exchanger compartment 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 62.2.) The sloped drain pan minimizes standing water in the drain. An external drain is provided. Downflow operation is easily provided in the field to allow vertical ductwork connections. The basepan utilizes knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode.
