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
RC
2
- 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.
MaxAlloy
TM
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.
