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 bolt­on 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.

MicroBlue

with the MicroBlue
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 prev ent 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 M otor - 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.
