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.
The SHP 48 & 60 models are upflow only models designed
into a shorter cabinet than the AHP version, for those special
applications where reduced height is required.
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 co nvert the air
handler to the required refrigerant. The UPG TXV is a true
bolt-on which does not require brazing to replace or install.
MicroBlue
with the MicroBlue
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.

ACCESSORIES
Refer to Price Manual for specific model numbers.
TXV Kits - TXV kits are available for “Flex-coil” applications
and converting R22 to R410A or as a service replacement.
All kits are bolt-on and require no brazing to install.
Non-Combustible Bases - A combustible floor base accessory is available, if required by local codes, when the air handler is installed in the downflow position on a combustible
material.
Electric Heaters - 4HK models shown under electrical data
include sequential operation and temperature dual limit
switches for safe, efficient operation. Circuit breakers are provided where shown.
External Insulating Wrap Kit - Provides a vinyl covered
thermal insulation wrap, providing additional thermal insulation protection to prevent sweating in applications where
extreme high humidity is present. Air Handler cover (or wrap)
has Velcro edges for easy installation and access.
