DESCRIPTION

These cooling and heat pump coils are designed to be installed with UPG furnaces and to be matched with UPG cooling and heat pump outdoor units. All coils are available as sweat-connect models for your convenience and ease of matching.

Upflow Coils - Available in high-capacity models to match any system and upflow furnace. Models available with factory installed TXV or orifice metering system.

Multi-Position Coils - Available in high-capacity models to match any system and any multi-position furnace and air handler. Models available with factory installed TXV or orifice metering system.

Horizontal Duct Coils - Available to match any cooling or heat pump system and horizontal furnace. Field transition may be required.

Dedicated Horizontal Cased Coils - Available to match most cooling or heat pump systems and any horizontal gas furnace or modular air handler. For horizontal application only. Models available with factory installed TXV or orifice metering system.

FEATURES

Insulated Cabinet - All evaporator coil cabinets are thermally insulated to prevent sweating.

Internally Clean - All evaporator coils are factory leaktested, dehydrated, sealed and shipped with a holding charge.

Durable Finish - Coil casings are made of pre-painted steel. The pre-treated flat galvanized steel provides a better paint to steel bond, which resists corrosion and rust creep.

Optimum Heat Transfer - Using the latest in heat transfer technology, staggered rows of rifled copper tubes are mechanically expanded into aluminum fins to provide optimum air to surface contact for ample moisture removal as well as high performance ratings.

Optional Factory Installed Thermal Expansion Valve -

Provides flexibility to match high efficiency applications at a lower installed cost.

Yorkmate Refrigerant Control - Provides optimum system performance and the flexibility to match coils with any efficiency level cooling or heat pump system.

ACCESSORIES

Refer to Price Manual for specific model numbers.

TXV Kits - Thermal expansion valve kits are available for indoor coils to obtain specific system performance.

Horizontal Drain Pan Kits - A field installed horizontal drain pan kit (1HP0623BK or 1HP0628BK) is available for horizontal applications on the multi-position coil. The full cased multiposition coil is also available with a factory installed horizontal drain pan option.

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