Allied Air 1.911483 Evaporator Coil 2.5-3 Ton Downflow

Product Description

The ALLIED AIR 1.911483 is a cased evaporator coil rated for 2.5 to 3 ton nominal cooling capacity, designed for downflow air handler and furnace applications. It ships fully enclosed in a cased enclosure, reducing field fabrication time and protecting the coil assembly during installation. The liquid line connection measures 3/8 inches and the suction line measures 7/8 inches, matching common residential split-system refrigerant line sets. This coil carries no integrated heating capacity and is intended to work in combination with a matched condensing unit and air handler or furnace. Licensed HVAC technicians are the typical installing trade for this component.

This evaporator coil is suited for residential split-system cooling installations where a downflow configuration is required. Downflow systems move conditioned air downward through the cabinet, making this coil appropriate for attic-mount or closet-style air handlers and downflow furnace configurations. The cased enclosure allows for direct installation into the system without additional sheet metal fabrication at the coil cabinet. Nominal capacity of 2.5 to 3 tons makes it a common fit for mid-size residential cooling loads.

Key Features

• Nominal cooling capacity of 2.5 to 3 tons for mid-size residential applications
• Downflow air configuration for compatibility with downflow furnaces and air handlers
• Cased enclosure eliminates the need for field-built coil cabinets
• 3/8-inch liquid line and 7/8-inch suction line connections for standard residential line sets
• No integrated heating capacity — pure cooling coil designed for split-system pairing

Compatibility

Designed as an OEM-style replacement or new-installation evaporator coil for residential downflow split-system cooling applications with a 2.5 to 3 ton nominal capacity requirement.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and manufacturer guidelines. Disconnect and lock out power to the air handler or furnace before beginning coil installation. Shut off refrigerant flow and recover any system charge per EPA Section 608 requirements before disconnecting line sets. Verify refrigerant line sizing, coil orientation, and drain pan positioning before completing the installation and recharging the system.
