Adp HG36A36A155A0004R Uncased A-coil 15.5in Lh R-454B Txv

Product Description

The ADVANCED DISTRIBUTOR PRODUCTS HG36A36A155A0004R is an uncased A-coil designed for split-system air conditioning and heat pump applications. Built for left-hand (LH) orientation, it features a B width of 15.5 inches and a height of 23 inches, making it suitable for residential and light commercial air handler installations. The coil ships with an R-454B thermostatic expansion valve (TXV) and an RDS kit, providing the hardware needed for a compliant, low-global-warming-potential refrigerant installation. Licensed HVAC technicians handle installation as part of new system builds or coil replacements in existing ductwork configurations.

This uncased A-coil is intended for installations where the coil is housed within an existing air handler cabinet or field-fabricated enclosure. Its left-hand orientation suits specific unit configurations where the suction and liquid line connections must exit from the left side. The included R-454B TXV is matched to the coil for proper refrigerant metering with A2L refrigerant systems. Per the raw product data, this coil is noted as compatible with Allied 2.5 and 3 ton 7AC units, making it a direct-fit option for those systems.

Key Features

• Left-hand (LH) orientation for compatible air handler cabinet configurations
• B width of 15.5 inches fits standard residential coil cabinet openings
• 23-inch height suits typical upflow and horizontal system installations
• Includes R-454B TXV for proper refrigerant metering with A2L refrigerant
• RDS kit included for a complete, ready-to-install coil assembly

Compatibility

Compatible with Allied 2.5 and 3 ton 7AC units per product data. The uncased design requires a field-supplied or existing cabinet enclosure for installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R-454B is a mildly flammable refrigerant class requiring specific handling precautions and compliant equipment. Shut down and lock out the entire system, including the air handler and outdoor unit, before removing or installing the coil. Verify the cabinet orientation and drain pan position before securing the coil, and confirm all refrigerant connections are leak-tested after installation per local mechanical codes. Follow all applicable EPA Section 608 regulations and manufacturer guidelines when working with R-454B refrigerant systems.
