DESCRIPTION The AHV Air Handler line offers the ultimate in comfort, sound and application flexibility. This unit may be used for upflow, downflow, horizontal right, or horizontal left applications. No special kits are required to install this deluxe product.036-21047-001 Rev. A (4/00) Air handlers are shipped with “Flex-coils” without a factory installed metering device. Flex coil models allow these coils to be used with R-22 or R-410A for added flexibility to meet refrigerant choices. An orifice metering device or a R-410A TXV should be installed in the field to meet your system requirements. TECHNICAL GUIDE SINGLE PIECE ECM AIR HANDLERS FOR USE WITH SPLIT-SYSTEM AIR CONDITIONERS & HEAT PUMPS MODELS: AHV18 THRU 60 Thermostatic 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. Rust-proof Plastic Drain Pans - The vertical and horizontal drain pans in these units are made of a fiberglass reinforced thermoset polymer that will not rust or compromise stability at high temperatures. 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 leakage 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 steel. Filters - All models have internal filter racks provided for use with 1” thick standard size filters. Electric Heat Kits - The 6HK series of field installed electric heat kits are available for installation friendly and easy service applications. These 6HK kits have heat capacities from 2 kW to 25 kW to meet the application requirements. ECM Variable Speed Motor - Designed for efficient, quiet operation with added indoor comfort control. With the use of a humidistat, the system 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. The climate comfort system allows dealer to customize comfort settings based on regional location. ISO 9001 Certified Quality Management System Communications - These models may be connected as part of a communications system using a 4-wire connection bus. Due to continuous product improvement, specifications are subject to change without notice.
