These can be left in place if the units are converted to downflow. Standard horizontal metal duct covers with insulation come with the unit and cover the horizontal duct openings. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. The basepan with integrated drain pan provides easy ground level installation with mounting pad. Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA.Įasy to service cabinets provide easy 3-panel accessibility to serviceable components during maintenance and installation. The outdoor coil is internally mounted on the top tier of the unit. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. Indoor and Outdoor coils are computer-designed for optimum heat transfer and efficiency. High Pressure Switch provides added reliability for the compressor. Refrigerant service connections make checking operating pressures easier. Each unit leaves the factory with a full refrigerant charge. Liquid filter driers are used to promote clean, unrestricted operation. Refrigerant system is designed to provide dependability. If a non-corporate thermostat without anti-short cycle protection is used the Time Guard® II field-installed anti-short cycle kit is recommended. Time Guard® II anti-short cycle protection circuitry. Motormaster® II low ambient kit is available as a field-installed accessory. In addition, dimples located on the heat exchanger walls force the hot gases to stay in close contact with the walls, improving heat transfer.ĭirect-drive PSC (Permanent Split Capacitor) condenser-fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40☏ (4.4☌) outdoor temperature. The tubular design permits hot gases to make multiple passes across the path of the supply air. Turbo-tubular™ heat exchangers are constructed of aluminized steel for corrosion resistance and optimum heat transfer for improved efficiency. All gas furnace components are accessible in one compartment. The large monoport on the inshot (or injection type) burners seldom, if ever, requires cleaning. Monoport inshot burners produce precise air-to-gas mixture, which provides for clean and efficient combustion. Can be installed in air quality management districts with a 40 ng/J NOx emissions requirement. Low NOx units are designed for California installations and meet 40 ng/J NOx emissions. A low-cost field installed kit for propane conversion is available for all units. Standard units are furnished with natural gas controls. Energy-saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. High-efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of 14.0, 11.5 EER, and AFUE (Annual Fuel Utilization Efficiency) ratings up to 81.0%. The basepan seals on the bottom openings to ensure a positive seal in the vertical airflow mode. Downflow operation is provided in the field to allow vertical ductwork connections. Each unit is converted from horizontal to downflow and includes two horizontal duct covers. Unit is designed for use in either downflow or horizontal applications. On the outside metal base rails provide added stability as well as easier handling and rigging. 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. The high tech composite base eliminates rust problems associated with ground level applications. Units are lightweight and install easily on a rooftop or at ground level. 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. Puron® refrigerant is in service in millions of systems proving highly reliable and is non-ozone depleting.įactory-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. 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 is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron® is Carrier’s unique refrigerant designed to be environmentally balanced. One-piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance.
