A (0105)FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE HeatingAir ConditioningRDESCRIPTIONT hese cooling and heat pump coils are designed to beinstalled with UPG furnaces and to be matched with UPGcooling and heat pump outdoor units.

2 All coils are availableas sweat-connect models for your convenience and ease Coils - Available in high-capacity models to matchany system and upflow furnace. Models available with factoryinstalled TXV or orifice metering Coils - Available in high-capacity models tomatch any system and any multi-position furnace and airhandler. Selected models available with factory installed TXVor standard orifice metering systems. Selected models alsoavailable from the factory with thicker 3/4 cabinet Duct Coils - Available to match any cooling orheat pump system and horizontal furnace.

3 Field transitionmay be Horizontal Cased Coils - Available to matchmost cooling or heat pump systems and any horizontal gasfurnace or modular air handler. For horizontal applicationonly. Models available with factory installed TXV or orificemetering Cabinet - All evaporator coil cabinets are thermallyinsulated to prevent Clean - All evaporator coils are factory leak-tested, dehydrated, sealed and shipped with a Finish - Coil casings are made of pre-painted pre-treated flat galvanized steel provides a better paint tosteel bond, which resists corrosion and rust Heat Transfer - Using the latest in heat transfertechnology.

4 Staggered rows of rifled copper tubes aremechanically expanded into aluminum fins to provide opti-mum air to surface contact for ample moisture removal aswell as high performance Factory Installed Thermal Expansion Valve -Provides flexibility to match high efficiency applications at alower installed Refrigerant Control - Provides optimum systemperformance and the flexibility to match coils with any effi-ciency level cooling or heat pump to Price Manual for specific model numbers. TXV Kits - Thermal expansion valve kits are available forindoor coils to obtain specific system Drain Pan Kits - A field installed horizontal drainpan kit (1HP0623BK or 1HP0628BK) is available for horizon-tal applications on the multi-position coil.
