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 cabi-
net, for those special applications where reduced height is
required. No special kits are required to install this deluxe prod-
uct in any position.
TECHNICAL GUIDE
All JCI Unitary Products air handlers and coils use a TXV to pro-
vide our customers with the optimum performance and refriger-
ant 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 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.
TM
MicroBlue
Coated Fins - All air handler coils are treated
TM
with the MicroBlue
hydrophilic coating to enhance the
removal of condensate during the refrigeration cycle and
TM
reduce the possibility of water blow-off. The MicroBlue coat-
ing also reduces the growth of germ causing microbes for a
healthier home environment.
Insulated Cabinet - All air handler cabinets are thermally insu-
lated 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 to achieve 2% or less leakage rate with or with-
out field installed filter at 1.0” water gauge external static pres-
sure.
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 Motor - Designed for efficient, quiet oper-
ation with added indoor comfort control. With the use of a humi-
distat, 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.
ISO 9001
Certified Quality
Management System
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.
Due to continuous product improvement,
specifications are subject to change without notice.

1. Airflow at nominal voltage, bottom return at 0.5 external static pressure, tested without filter installed, dry coil conditions.
2. These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to 0.6” w.c. static pressure.
3. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static.
4. Operation on duct systems with greater than 1.0” w.c. external static pressure is not recommended.
5. Both the COOL and the ADJUST tap must be set to obtain the cooling airflow desired (CFM).
6. The ADJ tap does not affect the HEAT tap setting.
7. Fan only airflow (CFM) = 63% of jumper selected COOL tap and ADJUST tap.
8. Low speed cooling used only with two stage outdoor units. (Speed is preset to 65% of high speed).
9. Dehumidification speed is 85% of jumper selected COOL tap and ADJUST tap.
10. When operating in both heat pump and electric heat modes, the airflow (CFM) will be per HEAT Tap CFM values only.
11. At some settings, LOW COOL and/or LOW HEAT airflow may be lower than what is required to operate an airflow switch on certain
models of electronic air cleaners. Consult the instructions for the electronic air cleaner for further details.
12. Airflow (CFM) indicator light (LED2) flashes once for every 100 CFM (i.e.: 12 Flashes is 1200 CFM) – blinks are approximate +/- 10%.

ACCESSORIES
LIMITATIONS
Refer to Price Manual for specific model numbers where not
shown.
These units must be wired and installed in accordance with all
national and local safety codes.
Voltage limits are as follows:
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.
1Normal Operating

Electric Heaters - 4HK models shown under electrical data
include sequential operation and temperature dual limit
switches for safe, efficient operation. Circuit breakers are pro-
vided where shown.
1.Rated in accordance with ARI Standard 110, utilization range
“A”.
External Insulating Wrap Kit - Provides a vinyl covered ther-
mal insulation wrap, providing additional thermal insulation pro-
tection to prevent sweating in applications where extreme high
humidity is present. Air Handler cover (or wrap) has Velcro
edges for easy installation and access.
Airflow must be within the minimum and maximum limits
approved for electric heat, evaporator coils and outdoor units.

2. Remove humidistat jumper on air handler control board.
3. For heat pump applications - set MODE jumper on air handler control board to the HP position.
4. To change quantity of heat during HP defrost cycle - reverse connections at W1 and W2 on air handler control board.
