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 refrig-

erant choices. An orifice metering device or a R-410A TXV

should be installed in the field to meet your system require-

ments.

FEATURES

Thermostatic Expansion Valve - Provides the ultimate refrig-

erant 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 insu-

lated 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 oper-

ation 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.

TYPICAL APPLICATIONS

ACCESSORIES

Refer to Price Manual for specific model numbers where not

shown.

TXV Kits - TXV kits are available for “Flex-coil” applications and

converting R-22 to R-410A or as a service replacement. All kits

are bolt-on and require no brazing to install.

Electric Heaters - 6HK models shown under electrical data

include sequential operation and temperature dual limit

switches for safe, efficient operation. Circuit breakers are pro-

vided where shown.

LIMITATIONS

These units must be wired and installed in accordance with all

national and local safety codes.

Voltage limits are as follows:

Airflow must be within the minimum and maximum limits

approved for electric heat, evaporator coils and outdoor units.
