DESCRIPTION

The AHV 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.

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.

FEATURES

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 Sp eed 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.

Communications - These models may be connected as part of
a communications system using a 4-wire connection bus.
