Description
Rheem 4 Ton Air Conditioner Split System: RA16AY48AJ2NA + RB2TY4824STANMJB10
This system pairs the Rheem RA16AY48AJ2NA air conditioner from the Endeavor Line Classic Plus Series with the RB2TY4824STANMJB10 air handler. It is an AHRI-matched combination (AHRI reference 217168523), which means the efficiency numbers below were certified for these two exact models working together. It provides central cooling, and the air handler can take an electric heat strip if you want electric heat from the same system.

Electric heat
This air handler ships with a factory-installed 10 kW electric heater, so no separate heat strip is needed.
Sizing and installation
Size the system from a room-by-room load calculation (ACCA Manual J) rather than square footage alone. Climate, insulation, windows and duct condition all change the load, and an oversized system short-cycles and leaves humidity behind.
The outdoor unit and air handler each need their own electrical circuit sized to the rating plate. The refrigerant line set, thermostat, condensate drain, pad and installation materials are sold separately. Because R-454B is a mildly flammable (A2L) refrigerant, installation and service require a licensed HVAC technician using A2L-rated tools and the manufacturer's procedures, which also keeps the warranty in force.
Common questions
Is this a matched system?
Yes. AHRI certificate 217168523 covers the RA16AY48AJ2NA with the RB2TY4824STANMJB10.
Does it come with a heat strip?
Yes. The air handler has a factory-installed 10 kW heater.
Can I reuse my old refrigerant lines?
Sometimes. Line sizes must match the outdoor unit and the lines must be clean, leak-free and compatible with R-454B. Your installer should inspect them and flush or replace them as needed.
