Resumen del manual
These versatile units are available in three distinct variations: (1) fan units without coil, electric heater, or controls; (2) fan-coii units without electric heater or controls, and (3) heating/cooling fan-coil units with electric heater and controls. Fan-coii units are available in four nominal coil sizes—042, 048, 060, and 062. Fan-Coil units with electric heaters, and the accessory heat packages for field-installation into the fan-coil units without heaters and the fan units, are available in heating sizes ranging from 7.5 to 30KW. Fan units are available in two sizes—003 and 004. Accessory electric heat packages and 510B Coils are available for field-installation to convert these fan units into conventional electric furnaces, fan-coil units, or heating/cooling fan-coii units. FEATURES WRAPAROUND FULLY INSULATED CABINET—One-piece heavy-duty steel construction helps eliminate casing noise. Fully insulated interior provides both thermal and acoustic isolation. The cabinet exterior is finished with an attractive silver sage enamel. SPECIAL DESIGN FEATURES—Application versatility of all units is enhanced by the spacesaving compact size and the installation flexibility of either upflow or downflow mounting attitudes. The downflow application requires accessory condensate drain pan kit P/N 306230-213 or-214. Refrigerant and condensate connections are provided on the front of fan-coil units for ease of installation. Separate access panels for the coil section and blower/control section on the cabinet front make these units totally serviceable from the front. A third front access panel provides easy access to the permanent-type air filter furnished with each unit. DIRECT-DRIVE MULTISPEED, PSC, BLOWER MOTORS have been carefully selected to minimize energy consumption while providing the airflow to meet the requirements of a wide variety of applications. A Molex connector simplifies speed changes. Blower and motor assembly is resiliency mounted to minimize vibration, and slides out for easy servicing. COMPUTER-DESIGNED INDOOR COILS provide for optimum heat transfer and cooling and/or heat pump heating efficiency. Flare refrigerant connections enable quick leak-proof connections, using our precharged refrigerant tubing sets. The accessory 510B Coils that are used with the fan units are the same coils provided in the fan-coil units. All coils have a condensate drain pan and contain a holding charge of R-22 refrigerant. CHECK-FLO-RATER—All coils have a Check-Flo-Rater for efficient and dependable refrigerant metering, and to eliminate the potential service requirements of other metering devices. Located external to the unit, the Check-Flo-Rater is readily accessible for piston changeout or maintenance. For added system reliability, all coils have a liquid-line strainer to help maintain clean, unrestricted operation. ELECTRIC HEAT PACKAGES are available either as factory-installed in the heating/cooling fan-coil units or as a field-installed accessory for the fan units and fan-coil units. The application flexibility of these heaters is increased with the availability of single- and three-phase power supply options. The 10-, 15-, and 20-KW single-phase optional heaters are available with or without circuit breakers for internal circuit protection. Sequencer control is used for incremental energizing and deenergizing of the heater elements. Field-installation of a heater into a unit has been made extremely easy—simply slide in the heater, secure with three screws, and plug-in three leads for blower motor control.
