DESCRIPTION
These evaporator coils are designed to be installed with UPG fur-
naces or modular air handlers and matched with UPG cooling
and heat pump outdoor units. All coil models are available as
“flex-coil” units without a factory installed metering device. Flex-
coil models allow these coils to be used with R-22 or R-410A for
added flexibility to meet refrigerant system choice. An orifice
metering device or a R-410A TXV should be installed in the field
to meet your system requirements.
FC Models, Full Case Coils - Full cased coils are suitable for
use in upflow or downflow applications.
MC Models, Multi-Position Coils - MC coils have the added
flexibility that allow them to be installed in any position - upflow,
downflow, or horizontal right or left. This coil can be easily
installed with a UPG furnace or modular air handler in any config-
uration.
PC Models, Partial Case Coils - These coils are designed for
installation on top of upflow furnaces. The partial case height on
these coils allows for the flexibility of fabricating the upper portion
of the coil casing in the field. The partial cased coils are for use in
upflow only applications.
UC Models, Uncased Coils - These coils are designed for instal-
lation on top of upflow furnaces, and they are to be used for only
upflow applications. The uncased coils allows field modification of
the furnace duct for the coil installation.
HD Models, Horizontal Duct Coils - Dedicated horizontal, slab
coil available for both cooling and heat pump applications. Field
transition may be required.
FEATURES
Rust-proof plastic drain pans - The vertical and horizontal drain
pans on these coils are made of a fiberglass reinforced thermoset
polymer that will not rust or compromise stability at high tempera-
tures.
Insulated Cabinet - Evaporator coil cabinets are thermally insu-
lated with foil faced insulation to prevent sweating. HD coils use
fiberglass Tuf-Skin® insulation.
Internally Clean - All evaporator coils are factory leak-tested,
dehydrated, sealed and shipped with a holding charge. The suc-
tion and liquid lines are sealed with spun copper fittings with easy
access to attach line set.
Durable Finish Inside and Out - Coil casings are made of pre-
painted steel. Pre-treated flat galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep. All
internal metal parts are made of G90 galvanized steel.
Optimum Heat Transfer - Using the latest in heat transfer tech-
nology, staggered rows of copper tubes are mechanically
expanded into aluminum fins to provide optimum air to surface
contact for ample moisture removal as well as high performance
ratings.
ACCESSORIES
Refer to Price Manual for specific model numbers.
TXV Kits - Thermal expansion valve kits are available for flex-coil
applications, for converting R-22 to R-410A refrigerant, or as a
service replacement. All TXV kits are non-braze. All connections
are bolt-on including the valve assembly and equalizer tube. No
orifice or any other metering device is to be used in conjunction
with the TXV.
Coil Casing Without Coil - Coil casings are available in four
widths that can be installed with the furnace or modular air han-
dler during initial installation. This option is available to allow the
installer the flexibility to add the coil at a later date without duct
modifications.
UVC Germicidal Light - The UVC technology effectively pre-
vents mold, bacteria, and other microorganisms that develop in
air handling systems. The UVC Light Kit provides safe, continu-
ous cleaning while actually saving money by reducing HVAC sys-
tem maintenance and energy consumption.
