1 TECHNICAL GUIDE SINGLE PIECE STANDARD ECM AIR HANDLERS FOR USE WITH SPLIT-SYSTEM COOLING & HEAT PUMPS MODELS: AHE18 THRU 60* DESCRIPTION The Air Handler line offers the ultimate in comfort, sound and application flexibility. The air handler is shipped ready to be installed in upflow, horizontal left or right position, with minor adjustments. No special kits are required to install this deluxe product. All JCI Unitary Products air handlers and coils use a TXV to provide our customers with the optimum performance and refrigerant control. Air handlers are shipped with Flex-coils without a factory installed metering device. For added flexibility, an R-22 or R-410A TXV or orifice can be field installed to meet your refrigerant choice. FEATURE Thermal Expansion Valve - Provides the ultimate refrigerant control required for today s high efficient product. The UPG bolton TXV provides easy installation to convert the air handler to the required refrigerant, which is a true bolt-on design that does not require brazing to replace or install. Insulated Cabinet - All air handler cabinets are thermally insulated with 3/4 foil faced insulation to prevent sweating. Factory Sealed - Achieves 2% or less total airflow leakage rate at duct blaster field test conditions for system airflow verification. Durable Finish Inside and Out - Air handler casings are made of pre-painted galvanized steel which provides a better paint to steel bond that resists corrosion and rust creep. All internal coil sheet metal parts are made of G60 galvanized or prepainted G30 galvanized. Filters - All models have internal filter racks provided for use with 1 thick standard size filters. Electric Heat Kits - New 6HK series of field installed electric heat kits are available for installation friendly and easy service applications. These 6HK kits are unique to these new models. High Efficiency Blowers - All models use high efficiency brushless DC motors to provide cooling SEER rating enhancement. Due to continuous product improvement, specifications are subject to change without notice. Visit us on the web at: Additional rating information can be found at: ISO 9001 Certified Quality Management System WARRANTY Standard 5-year limited parts warranty. Extended 10-year limited parts warranty when product is registered online within 90 days of purchase for replacement or closing for new home construction.
