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 -
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 -
with 3/4" foil faced insulation to prevent sweating.
Factory Sealed -
duct blaster field test conditions for system airflow verification.
Durable Finish Inside and Out -
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 -
thick standard size filters.
Electric Heat Kits -
available for installation friendly and easy service applications.
