48XL---A Infinity® 15 SEER Single---Packaged Air Conditioner and Gas Furnace System with Puron® (R---410A) Refrigerant Single Phase 2---5 Nominal Tons (Sizes 24---60) Product Data 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. Variable-Speed Blower motors provide better comfort and energy efficiency. Economical constant airflow which provides improved indoor air quality and more even temperatures from room to room; and reduced indoor noise due to lower air velocity. In addition, you’ll realize improved installation flexibility with 3 different airflow choices for best overall comfort. Easy installation Factory-assembled package is a compact, fully self-contained, combination gas heating/electric cooling unit that is pre-wired, pre-piped, and pre-charged for minimum installation expense. These units are available in a variety of standard and optional heating/cooling size combinations. Units are lightweight and install easily on a rooftop or at ground level. The high tech composite unit base eliminates rust problems associated with ground level applications.

Puron refrigerant 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. IdealHumidityt Technology featuring Infinityr control and Variable-Speed Blower motor and two-stages of cooling and heating provide greater comfort, humidity control, and energy efficiency. Convertible duct configuration Unit is designed for use in either downflow or horizontal applications. Each unit is converted from horizontal to downflow and includes 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. Efficient operation High-efficiency design with SEERs (Seasonal Energy Efficiency Ratio) of up to 15.5 and AFUE (Annual Fuel Utilization Efficiency) ratings as high at 80.1%. 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. 48XLN- units are dedicated Low NOx units designed for -A 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 or any other location where a Low NOx rule exists. Durable, dependable components Compressors have two stages of cooling and are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Vibration isolation provides quiet operation. Compressors have internal high-pressure and overcurrent protection. Monoport inshot burners produce precise air- -gas mixture, -towhich provides for clean and efficient combustion. The large monoport on the inshot (or injection type) burners seldom, if ever, 1

requires cleaning. All gas furnace components are accessible in one compartment. Turbo-tubulart heat exchangers are constructed of 409 stainless 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. Full featured ECM Motor is standard on all 48XL- models. -A Direct-drive, PSC (Permanent Split Capacitor) condenser fan motors are designed...
