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.

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.
