Allied Air ED1P-48C-1 Downflow Cased Evaporator Coil 4 Ton

Product Description

The ALLIED AIR ED1P-48C-1 is a 4-ton downflow cased evaporator coil designed for residential gas furnace systems. It sits in the supply air plenum below the furnace, absorbing heat from the air stream as refrigerant evaporates through the coil. The cabinet measures 21 inches wide, 19 inches deep, and 20 inches tall, fitting standard 21-inch cabinet furnace platforms. The liquid line connection is 3/8 inches and the vapor line connection is 7/8 inches. A fixed piston metering device is factory-installed, making this a straightforward drop-in for systems where a piston-style expansion device is specified. HVAC technicians working on split-system cooling or heat pump installations will find this coil sized for demanding residential and light commercial loads.

This coil is configured for downflow applications, meaning airflow moves from top to bottom through the coil assembly. It is intended for use with 21-inch cabinet gas furnaces in residential split-system cooling and heat pump setups. The cased design provides a sealed cabinet around the coil, reducing the need for field fabrication of a coil enclosure. The piston metering device is suited for systems where a fixed orifice expansion approach is appropriate for the matched outdoor unit.

Key Features

• 4-ton capacity for high-load residential and light commercial cooling applications
• Downflow orientation matches 21-inch cabinet gas furnace configurations
• Cased design eliminates the need for a field-built coil enclosure
• 3/8-inch liquid line and 7/8-inch vapor line connections for standard refrigerant piping
• Factory-installed piston metering device simplifies system setup
• 21-inch cabinet width fits common residential gas furnace platforms

Compatibility

Designed for use with 21-inch cabinet width gas furnaces in downflow split-system cooling and heat pump installations.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer guidelines. Shut off all electrical power and close the refrigerant service valves before opening the refrigerant circuit. The system must be evacuated to the required vacuum level before charging, and refrigerant handling must comply with EPA Section 608 regulations. Do not exceed the coil connection sizes specified for the liquid and vapor lines.
