A WARNING Do not disconnect electric power to this appliance without first turning off gas supply. Be sure power to equipment is shut off before maintenance or service. Fig. 1—Model 48KHA,KLA GENERAL Models 48KHA,KLA packaged gas/electric units (Fig. 1) are design certified in accordance with ANSI Z21.47B-1986, ARI Standard 210-81 and ARI Standard 270-84. The units are design certified by the American Gas Association (AGA) for use with natural or propane gases with appropriate controls or orifices. See Table 1 for heating input ratings. Models 48KHA.KLA units are fully self-contained, combination gas-heating/electric-cooling units designed for outdoor installation on either a rooftop or ground-level slab. May be installed directly on wood flooring or on Class A, Class B or Class C roof covering materials. These units are equipped with an energy-saving automatic, intermittent, electric spark ignition system that does not have a continuously burning pilot. All units are manufactured with natural gas controls. Units with number 1 in the 4th digit location of model number in Table 1 meet California oxides of nitrogen (NOx) maximum emission requirements. Units are factory charged with R-22 refrigerant. To install: connect gas supply, air ducts, high- and low-voltage wiring and condensate drain, and install a field-supplied air filter in the return-air ductwork. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

For 3-phase units, the efficiency rating is a product thermal efficiency rating determined under continuous operating conditions, independent of any installed system. All units can be connected into existing duct systems that are properly sized and designed to handle an airflow of 350 to 450 cfm per each 12,000 Btuh of rated cooling capacity. See Table 8 for cooling and heating airflow requirements. NOTE: When installing any accessory item, see Installation Instructions packaged with accessory. IMPORTANT-READ BEFORE INSTALLING 1. This installation must conform with all applicable local and national codes. 2. Power supply (volts, hertz and phase) must correspond to that specified on unit rating plate. 3. Electrical supply provided by utility must be sufficient to handle load imposed by unit. 4. Refer to Fig. 4 for locations of gas inlet, electrical inlets, condensate drain, duct connections, and required clearances before setting unit in place. 5. Locate unit where vent cap will be a minimum of 4 ft from openable windows or doors. 6. Installation must conform with local building codes and with National Fuel Gas Code, NFPA 54-1984/ ANSI Z223.1-1984. IMPORTANT: On some models, the high-voltage ignition cable is not connected t...
