DESCRIPTION
This fan coil line offers the ultimate in application flexibility. The
AHR (non-variable speed motor) models are shipped as upflow
models, that can be installed in upflow, horizontal right or left
without the need for additional field installed kits.
All JCI Unitary Products air handlers and coils use a TXV to pro-
vide our customers with the optimum performance and refriger-
ant control. Air handlers are shipped with "Flex-coils" without a
factory installed metering 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
control 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 brazing to replace or install.
Insulated Cabinet - All air handler cabinets are thermally insu-
lated 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 verifica-
tion.
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 - New 6HK series of field installed electric
heat kits are available for installation friendly and easy service
applications. These 6HK kits are unique to these new models.
