Carrier r4h5s36akaaa Heat Pump 3 Ton R-410A

Product Description

The CARRIER r4h5s36akaaa is a 3-ton residential split-system heat pump designed for R-410A refrigerant operation and rated at 15 SEER. It runs on a scroll compressor and ships factory-charged, reducing field refrigerant handling on most installations. A suction line accumulator is factory installed to protect the compressor from liquid slugging. Integrated solid-state controls with time-temperature defrost logic manage heating and cooling cycles automatically. High and low pressure switches are built in for system protection. Licensed HVAC technicians install and service this unit as part of a split-system configuration paired with a compatible air handler or furnace coil.

This unit is suited for residential applications requiring a single-phase split-system heat pump in the 3-ton capacity range. The copper tube and aluminum fin coil handles both heating and cooling loads. Easy-access service valves and external high and low refrigerant service ports are standard on all models, making routine maintenance and refrigerant checks straightforward in the field. The control panel is accessible with only two screws, reducing service time during diagnostic calls.

Compatibility

Designed as an OEM-style replacement or new-installation split-system heat pump for residential applications requiring a 3-ton R-410A outdoor unit paired with a compatible indoor air handler or furnace coil.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA 608 refrigerant-handling certification. Disconnect and lock out all electrical power to the system before servicing or making refrigerant connections. Follow local mechanical codes and manufacturer wiring diagrams when connecting low-voltage control wiring between the outdoor unit and air handler. Do not operate the unit below the minimum outdoor ambient temperature rating or without verifying that indoor airflow meets minimum CFM requirements for the coil.
