Adp HE35148A170A000076 Uncased Evaporator Coil 3.5-4 Ton

Product Description

The ADP HE35148A170A000076 is an uncased slab evaporator coil rated for 3.5 to 4 ton residential and light commercial air conditioning and heat pump systems. It delivers 48,000 BTU/h of cooling capacity at 1,600 CFM and is charged for use with R-410A refrigerant. The coil features a copper slab construction with a high-efficiency lanced fin design and a factory-installed piston metering device (size 76). The cabinet is galvanized steel. Multi-position orientation allows flexible installation in a range of air handler configurations. Licensed HVAC technicians perform installation and refrigerant handling on this type of component.

This coil is designed for multi-position installation in residential and light commercial split-system air conditioners and heat pumps using R-410A. With a width of 17 inches, a depth of 19.5 inches, and a height of 21 inches, it fits standard uncased coil applications where the installing contractor supplies or reuses an existing cabinet. Refrigerant line connections are 7/8 inch (suction) and 3/8 inch (liquid), using copper connections suitable for brazing on both copper and aluminum slab models. The piston metering device uses an externally accessible body, making piston changeout or field TXV conversion straightforward.

Key Features

• High-efficiency lanced fin design for improved heat transfer
• Copper slab construction with copper refrigerant connections for easy brazing
• Piston size 76 with externally accessible body for simple piston swap or TXV field kit installation
• Air pressure tested at 500 psi and helium leak tested; sealed with rubber plugs and charged with dry nitrogen for shipping integrity
• Microban antimicrobial additive in the UV-resistant, high-temperature engineered polymer drain pan to inhibit mold and mildew growth
• Dual 3/4 inch FPT condensate drains on front-left and front-right of drain pan for flexible condensate routing
• Patented low water retention drain pan design reduces standing water

Compatibility

Designed for use in R-410A split-system air conditioners and heat pumps. Compatible with both AC and heat pump applications per manufacturer documentation. Threaded expansion valves are available factory installed or as a field-installed kit for systems requiring TXV metering.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-410A refrigerant under applicable EPA Section 608 requirements. Shut down and lock out the system power and close refrigerant service valves before connecting or disconnecting the coil. Refrigerant connections are copper and intended for brazing; follow standard brazing procedures and purge lines with dry nitrogen during the process to prevent internal oxidation. Verify condensate drain routing and trap sizing comply with local mechanical codes before startup.
