FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
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 use a TXV to provide our
customers with the optimum performance and refrigerant control. Air
handlers are shipped with “Flex-coils” without a factory installed meter-
ing device. For added flexibility, an R-22 or R-410A TXV or orifice can
be field installed to meet your refrigerant choice.
FEATURES
Thermal Expansion Valve - Provides the ultimate refrigerant con-
trol required for today’s high efficient product. The UPG bolt-on TXV
provides the added flexibility to convert the air handler to the required
refrigerant. The UPG TXV is a true bolt-on which does not require braz-
ing to replace or install.
Insulated Cabinet - All air handler cabinets are thermally insulated
with 3/4” foil faced insulation to prevent sweating.
Factory Sealed - Achieves 2% or less total airflow leakage rate at
duct blaster field test conditions for system airflow verification.
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 G60 galvanized or prepainted G30 galvanized.
Filters - All models have 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.
