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.

Coated Fins - All air handler coils are treated

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

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 - 4HK models shown under electrical data include sequential operation and temperature dual limit switches for safe, efficient oper ation. Circuit breakers are provided where shown.

External Insulating Wrap Kit - Provides a vinyl covered thermal insulation wrap, providing additional thermal insulation protection to prevent sweating in applications where extreme high humidity is present. Air Handler cover (or wrap) has Velcro edges for easy installation and access.

S1-1JV0117 S1-1JV0121 S1-1JV0124 S1-1JV0224 (SV* models only)

Humidstat - S1-2HU16700124 Control when used with ECM variable speed models will moni-

tor humidity level in both winter and summer seasons. Adjusts blower speed and airflow provided to maintain desired humidity levels.

LIMITATIONS

These units must be wired and installed in accordance with all national and local safety codes.

Voltage limits are as follows:

Air Handler Voltage Voltage code

208/230-1-60 06 187-253

1.Rated in accordance with ARI Standard 110, utilization range “A”.

Airflow must be within the minimum and maximum limits approved for electric heat, evaporator coils and outdoor units.

* Optional dehumidification humidistat switch contacts open on humidity rise.

NOTES:

1. “Y/Y2” Terminal on air handler control board must be connected for full CFM and applications requiring 60 second blower off delay for SEER enhancement.

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.
