256819-YTG-J-1208 DESCRIPTION The Affinity Air Handler line offers the ultimate in comfort, sound and application flexibility. The Affinity models utilize a whisper quiet variable speed motor that provides humidity control and the lowest operating cost in the industry. The AVY air handler is shipped ready to be installed in all positions, upflow, downflow, horizontal left or right, with minor adjustments. The SVY 48 & 60 models are upflow only models designed into a shorter cabinet, for those special applications where reduced height is required. No special kits are required to install this deluxe product in any position. All JCI Unitary Products air handlers and coils use a TXV to provide our customers with the optimum performance and refrigerant control required for 13 + Seer systems. Air handlers can be ordered with either a R-22 or R-410A TXV factory installed. Air handlers are also available with “Flex-coils” without a factory installed metering device, where for added flexibility, a R-22 or R-410A TXV 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 bolt- on 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. MicroBlueTM Coated Fins - All air handler coils are treated with the MicroBlueTM hydrophilic coating to enhance the removal of condensate during the refrigeration cycle and reduce the possibility of water blow-off. The MicroBlueTM coating also reduces the growth of germ causing microbes for a healthier home environment. Insulated Cabinet - All air handler cabinets are thermally insulated with 1” foil faced insulation (R-4.2) to prevent sweating. For applications in extreme humidity conditions an optional, field installed, external insulating wrap kit is also available. Factory - Sealed to achieve 2% or less leakage rate with or without field installed filter at 1.0” water gauge external static pressure. 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 G90 galvanized. New 4 HK Heat Kit -Installation friendly, easy service, more robust, unique to new design. ECM Variable Speed Motor - Designed for efficient, quiet operation with added indoor comfort control. With the use of a humidistat, the motor will monitor the humidity in the home and automatically keep the desired humidity level in both winter and summer seasons. The ECM motor utilizes only 24% of the energy used by standard blower motors to reduce your overall heating and cooling costs. ClimaTrak Comfort Settings - Installers can set an operating cycle for the ECM motor that works best in a particular climate. Homeowners benefit from an operating cycle that maximizes their indoor comfort level regardless of whether they live in a dry, temperate, or humid climate.
