DESCRIPTION
This fan coil line offers the ultimate in application flexibility. This
unit may be used for upflow, downflow, horizontal right, or
horizontal left applications.
All JCI Unitary Products air handlers and coils can use a TXV to
provide our customers with the optimum performance and
refrigerant control. Single piece air handlers are available with
“Flex-coils” (without a factory installed metering device). For
added flexibility, an R-22 or R-410A TXV or piston must be field
installed to meet the requirement of the desired refrigerant.
Some coil models available with factory installed TXV.
FEATURES
RC2-Rigid Case Construction interior endoskeleton for
structural support, smooth side, and locks in insulation.
Powder-painted -G30 galvanized steel case provide a coated
edge that resists corrosion and rust creep.
MaxAlloyTM Coil - Long life aluminum coils built to deliver
lasting performance, efficiency and reliability.
Quality Construction - Structural components are made of
Aluminum or G90 galvanized steel to prevent corrosion.
Improved Insulation Design - Single piece with no external
screws to reduce thermal transmission paths to prevent
sweating. Foil faced insulation for ease of cleaning.
Thermostatic Expansion Valve - The accessory chatleff style
TXV provides easy installation to convert the indoor coil to the
required refrigerant that does not require brazing to replace or
install. Some models are available with factory installed TXV.
Case Depth -These models have 20.5” casing which provide
ease of attic access and tight applications.
Thermoset Drain Pan - Low retention and positive slope for
drainage to reduce potential mold or contaminants.
Factory Sealed - Achieves 2% or less total airflow leakage rate
at duct leakage test conditions in positive and negative
pressure for system airflow verification.
Enhanced Filter Rack -All models have integrated internal
filter racks provided for use with 1” thick standard size filters.
Electric Heat Kits -6HK series of field installed electric heat
kits are available for installation-friendly and easy service
applications.
Blowers - All models use direct-drive, variable speed ECM
motors.

ACCESSORIES
Refer to Price Manual for specific model numbers where not
shown.
TXV Kits - Air handlers are shipped with “Flex-coils” without a
factory installed metering device. For added flexibility, an R-22
or R-410A TXV or piston can be field installed to meet your
refrigerant choice. All TXV kits are chatleff style and require no
brazing to install. Some models are available with a factory
installed TXV.
Electric Heaters - 6HK models shown under electrical data
include sequential operation and temperature dual limit
switches for safe, efficient operation. Service disconnects are
provided where shown.
Combustible Floor Base Accessory - If an electric heat
accessory which is rated for greater than zero clearance to
combustible surfaces is installed in these air handlers in the
downflow operating positions on a combustible floor, one of the
following combustible floor base accessory models is required:
S1-1FB1917, S1-1FB1921, S1-1FB1924.
Breaker Moisture Seal Accessory - A clear circuit breaker
moisture barrier seals the breakers from humidity and dust. The
flexibility of the clear cover allows circuit breakers to be turned
ON or OFF without removing the cover. The cover firmly
attaches to the access panel around the circuit breakers with
the use of double backed adhesive tape. To ensure that
moisture or dust does not contaminate circuit breakers, an S1-
02435672000, Circuit Breaker, Cover Seal may be ordered.
Thermostat - Compatible thermostat controls are available
through accessory sourcing. For optimum performance, these
outdoor units are fully compatible with our York touch screen
thermostat with proprietary (patent-pending) hexagon interface.
For more information, see the thermostat section of the Product
Equipment Catalog.

TYPICAL THERMOSTAT CONNECTION
*Optional dehumidification humidistat switch contacts open on humidity rise.
NOTES:
1. “Y/Y2” Thermostat wire must be connected for full CFM and applications requiring 60 second blower off delay for SEER enhancement.
2. Move HUM STAT jumper on air handler control board to YES position if humidistat is used.
3. For heat pump applications - set AC/HP jumper on air handler control board to the HP position.

Dry coil conditions only, tested without filters.
For optimal performance, external static pressures of 0.2" to 0.5" are recommended. Heating applications tested at 0.50” w.c. esp.Above 0.5" CFM is reduced by
2% per 0.1" increase in static.
2. The ADJ tap does not affect the HEAT tap setting.
Low speed cooling used only with two stage outdoor units. Speed is preset to 65% of high speed.
Dehumidification speed is 85% of jumper selected COOL tap and ADJUST tap.
When operating in both heat pump and electric heat modes, the airflow (CFM) will be per HEAT tap CFM values only.
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.
Airflow (CFM) indicator light (LED2) flashes once for every 100 CFM (i.e.: 12 flashes is 1200 CFM) - blinks are approximate +/- 10% of actual CFM.
