2 All coil models areavailable as flex-coil units without a factory installed meteringdevice. Flex-coil models allow These coils to be used with R-410A or R-22 for added flexibility to meet refrigerant systemchoice. A piston or TXV metering device should be installed inthe field to meet your system Models, Full Case coils - Full cased coils are suitable foruse in upflow or downflow Models, Multi-Position coils - CM coils have the addedflexibility that allow them to be installed in any position - upflow,downflow, or horizontal (right or left). This coil can be easilyinstalled with a UPG furnace or modular air handler in Models, Uncased coils - These coils are designed forinstallation on top of upflow furnaces, and they are to be usedfor upflow only applications.

3 The uncased coils require fieldmodification of the furnace duct for the coil installation. FEATURESRC2 - Rigid Case Construction interior endoskeleton forstructural support, flush side, and locks in insulation. Powder-painted - G30 galvanized steel case provide a coatededge that resists corrosion and rust creep. MaxAlloyTM Coil - Long life aluminum coils built to deliverlasting performance, efficiency and reliability. Quality Construction - Structural components are made ofAluminum or G90 galvanized steel to prevent corrosion. Improved Insulation Design - Single piece with no externalscrews to reduce thermal transmission paths to preventsweating.

4 Foil faced insulation for ease of Expansion Valve - Bolt-on TXV provides easyinstallation to convert the indoor coil to the required refrigerantthat does not require brazing to replace or install. Some modelsare available with factory installed TXVs. Case Depth - These models have casing which provideease of attic access and tight applications. Thermoset Drain Pan - Positive slope for drainage to reducecause for potential mold or to Price Manual for specific model Kits - Thermal expansion valve kits are available for flex-coil applications with R-410A refrigerant. All TXV kits are non-braze.

5 All connections are bolt-on including the valve assemblyand equalizer tube. No orifice or any other metering device is tobe used in conjunction with the Case Available to be used with CU coils in four option is intended for upflow applications where heightlimitations in the application prevent the installation of full casedcoils. The partial case design allows the top section of theindoor coil to be installed in the duct or plenum. Coil Casing Without Coil - Coil casings are available in fourwidths that can be installed with the furnace or modular airhandler during initial installation.

6 This option is available to allowthe installer the flexibility to add the coil at a later date withoutduct Germicidal Light - The UVC technology effectivelyprevents mold, bacteria, and other microorganisms thatdevelop in air handling systems. The UVC Light Kit providessafe, continuous cleaning while actually saving money byreducing HVAC system maintenance and energy Controls Unitary ProductsLIST OF SECTIONSDESCRIPTION .. 1 FEATURES .. 1 ACCESSORIES .. 1 NOMENCLATURE .. 2 DIMENSIONS CF .. 3 DIMENSIONS CM .. 3 DIMENSIONS CU .. 4 COOLING CAPACITY - UPFLOW N TYPE COIL (COIL ONLY).
