DESCRIPTION
This new fan coil line offers the ultimate in application flexibil-
ity. 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
customers with the optimum performance and refrigerant
control required for 13+ systems. Air handlers can be ordered
with a R22 TXV factory installed that can be easily converted
to R410A by changing the bolt-on TXV. Air handlers are also
available 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.
TM
MicroBlue Coated Fins - All air handler coils are treated
TM
with the MicroBlue hydrophilic coating to enhance the
removal of condensate during the refrigeration cycle and
reduce the possibility of water blow-off. The MicroBlue
coating also reduces the growth of germ causing microbes
for a healthier home environment.
Insulated Cabinet - All air handler cabinets are thermally
insulated 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.
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 pre-painted
steel i.e. triangular plates, top plates, horizontal supports etc.
Coil header plates are not painted due to the brazing process
during production. The coil header plates are treated after the
brazing process with a corrosion resistant spray to reduce the
probability of rust.
High Efficiency - 5 ton unit has high efficiency DC motor.
New 4 HK Heat Kit - Installation friendly, easy service, more
robust, unique to new design.
