DESCRIPTION

These indoor coils are designed to be installed with UPG fur­naces 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. Flex­coil models allow these coils to be used with R-410A or R-22 for
added flexibility to meet refrigerant system choice. A piston or
TXV metering device should be installed in the field to meet
your system requirements.

CF Models, Full Case Coils - Full cased coils are suitable for
use in upflow or downflow applications.

CM Models, Multi-Position Coils - CM 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 con­figuration.

CU Models, Uncased Coils - These coils are designed for
installation on top of upflow furnaces, and they are to be used
for upflow only applications. The uncased coils require field
modification of the furnace duct for the coil installation.

FEATURES

RC2 - Rigid Case Construction interior endoskeleton for struc-

tural support, flush side, and locks in insulation.
Powder-painted - G30 galvanized steel case provide a coated

edge that resists corrosion and rust creep.

MaxAlloy

TM

Coil - Long life aluminum coils built to deliver last-

ing performance, efficiency and reliability.
Quality Construction - Structural components are made of

Aluminum or G90 galvanized steel to prevent corrosion.
Improved Insulation Design - Single piece with no external

screws to reduce thermal transmission paths to prevent sweat­ing. Foil faced insulation for ease of cleaning.

Thermostatic Expansion Valve - Bolt-on TXV provides easy
installation to convert the indoor coil to the required refrigerant
that does not require brazing to replace or install. Some models
are available with factory installed TXVs.

Case Depth - These models have 20.5” casing which provide
ease of attic access and tight applications.

Thermal Plastic Drain Pan

- Positive slope for drainage to

reduce cause for potential mold or contaminates.

FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

ACCESSORIES

Refer to Price Manual for specific model numbers.
TXV Kits - Thermal expansion valve kits are available for flex-

coil applications with R-410A refrigerant. All TXV kits are non­braze. 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.

Partial Case – Available to be used with CU coils in four widths.
This option is intended for upflow applications where height lim­itations in the application prevent the installation of full cased
coils. The partial case design allows the top section of the
indoor coil to be installed in the duct or plenum.

Coil Casing Without Coil - Coil casings are available in four
widths that can be installed with the furnace or modular air han­dler 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 pre­vents mold, bacteria, and other microorganisms that develop in
air handling systems. The UVC Light Kit provides safe, continu­ous cleaning while actually saving money by reducing HVAC
system maintenance and energy consumption.
