Adp S42R155 Heat Pump Evaporator Coil 42000 Btu/h 5 Ton

Product Description

The ADP S42R155 is a cased evaporator service coil designed for residential and light-commercial air conditioner and heat pump systems. Rated at 42000 BTU/h with a 1400 CFM airflow capacity, this coil handles R-22 and R-410A refrigerants and ships ready for TXV or piston metering device configurations. The high-efficiency lanced fin design maximizes heat transfer surface area while keeping static pressure manageable. Licensed HVAC technicians performing system replacements or service upgrades install this coil as an OEM-style drop-in solution. A Microban antimicrobial additive in the drain pan inhibits mold and mildew growth, and the UV-resistant engineered polymer drain pan is rated to 450 degrees F.

This coil is suited for right-hand upflow installations in residential split-system heat pump and air conditioning applications. The copper refrigerant connections support easy brazing on both copper and aluminum slab models, and non-captive refrigerant lines with long stubs simplify field connections. Dual 3/4 inch FPT condensate drains are located on the front-left and front-right sides of the drain pan, providing flexible condensate piping options. The copper distributor tube assembly uses brass-to-brass threads, making TXV service straightforward in the field. Compatible with Ruud system applications as indicated by the part designation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and manufacturer guidelines. Shut off all electrical power to the air handler and disconnect refrigerant circuits before removing the existing coil. Follow EPA Section 608 requirements for refrigerant recovery prior to opening the system. Verify drain pan pitch and condensate line slope before returning the system to service.
