This air handler line offers the ultimate in application flexibility. The AHX (high efficiency motor) models can only be ordered as multi-position. These multi-position model can be installed in downflow, upflow, horizontal right or left except AHX60 two piece model, which is ordered as upflow or horizontal right unit and has to be disengaged, repositioned and reassembled for horizontal left or downflow applications.

All UPG air handlers and coils utilize a field installed TXV to provide our customers with the optimum performance and refrigerant control required for 13 SEER split systems. All air handlers are available with “Flex-coils” without a factory installed metering device. For added flexibility, an R22 or R410A TXV can be field installed to meet your refrigerant choice.

• Thermal Expansion Valve - Provides the ultimate refrigerant control required for today’s high efficient product. The UPG field installed bolt-on TXV provides the added flexibility to convert the air handler to the required refrigerant. The UPG TXV is a true bolt-on which does not require brazing to replace or install.
• 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 - 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 G90 galvanized.
• High Efficiency Blowers - All models use high efficiency brushless DC motors to provide cooling SEER rating enhancement.
  4 HK Heat Kit - Installation friendly, easy service, more robust, unique to new design.
• Filters - All models have an internal filter rack provided except for the AHX60 which requires an external filter rack.

*Must be installed on or after May 1st, 2009, and registered online within 90 days of installation. Otherwise, the warranty reverts to the standard warranty as published in the product warranty certificate.
