DESCRIPTION
This fan coil line offers the ultimate in application flexibility. The
AHP (non-variable speed motor) models can be ordered upflow
only or as multi-position. The multi-position model can be
installed in downflow, upflow, horizontal right or left without the
need for additional field installed kits.
All UPG air handlers and coils utilize a TXV to provide our cus-
tomers with the optimum performance and refrigerant control
required for 13+ SEER systems. Air handlers can be ordered
with R410A TXV factory installed. Air handlers are also avail-
able with "Flex-coils" without a factory installed metering device.
For added flexibility, an R22 or R410A TXV 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 1" foil faced insulation (R-4.2) to prevent sweating.
For applications in extreme humidity conditions an optional,
field installed, external insulating wrap kit is also available.
Factory - Sealed to achieve 2% or less leakage rate with or
without field installed filter at 1.0" water gauge external static
pressure.
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 G90 galvanized.
High Efficiency - 5 ton unit has high efficiency DC motor.
4 HK Heat Kit - Installation friendly, easy service, more robust,
unique to new design.
