Rheem Select 4 Ton 14.3 SEER2 Heat Pump Condenser

WP14AY48AJ2NA Rheem Select 4 Ton Heat Pump

WP14AY48AJ2NA is a Rheem Select outdoor heat pump condenser engineered to deliver dependable cooling and heating for compatible residential split systems. Its nominal 4 ton capacity makes it suitable for properties that require substantial year-round comfort, subject to a professional HVAC load calculation. This outdoor unit combines two-stage operation, durable construction and modern R-454B refrigerant technology.

Unlike a straight-cool air conditioner, this heat pump can reverse the refrigeration cycle to provide both cooling during warm weather and heating during cooler conditions. That makes it an excellent option for an all-electric HVAC system when paired with the correct indoor air handler, controls and approved accessories.

Efficient Two-Stage Comfort

The WP14AY48AJ2NA features a two-stage scroll compressor that can operate at lower or higher capacity according to the demand placed on the system. Low-stage operation can help maintain steadier indoor temperatures, improve humidity control and reduce unnecessary cycling during periods of moderate demand. High-stage operation provides additional capacity when outdoor conditions become more demanding.

With the specified matched indoor equipment, this model achieves 14.3 SEER2, 9.0 EER2 and 7.5 HSPF2. Actual efficiency and capacity depend on the complete AHRI-rated system combination, duct design, airflow, thermostat configuration and installation quality. The condenser alone does not establish the final efficiency rating of the complete HVAC system.

4 Ton Heating and Cooling Capacity

The WP14AY48AJ2NA has a nominal capacity designation of 48,000 BTU per hour. Rheem lists approximately 45,500 BTU per hour of total cooling capacity when matched with the specified H2TY4821STANN air handler under published rating conditions. Heating performance is approximately 44,000 BTU per hour at 47°F and 27,500 BTU per hour at 17°F with that published combination.

Equipment tonnage should never be selected using square footage alone. Climate, insulation, window area, ceiling height, air leakage and ductwork all affect the required capacity. A qualified HVAC professional should complete a Manual J load calculation and verify the approved indoor equipment match before ordering.

R-454B Refrigerant Technology

This Rheem heat pump uses R-454B, a lower-global-warming-potential refrigerant introduced for newer residential HVAC equipment. Because R-454B is classified as an A2L refrigerant, the system must be installed and serviced using appropriate procedures, tools and safety requirements. Every indoor and outdoor component must be approved for R-454B operation.

The WP14AY48AJ2NA is factory supplied with approximately 115 ounces of refrigerant. Final refrigerant adjustments depend on the installed line-set length and Rheem’s charging instructions. The system also incorporates Rheem’s PlusOne Refrigerant Detection System design to support the required refrigerant monitoring and mitigation functions when used with compatible indoor equipment.

Durable and Service-Friendly Construction

A fully louvered steel cabinet helps protect the outdoor coil from weather exposure and common yard hazards. Rheem’s expanded valve area provides additional working space around important service connections, while the inverted reversing valve is designed to support reliable heat-pump operation. The outdoor fan assembly moves approximately 4,096 CFM under listed conditions.

The WP14AY48AJ2NA measures approximately 35.17 inches high, 33.66 inches wide and 33.66 inches deep. Its listed operating weight is approximately 253 pounds, and its published sound level is 74 dB. These specifications should be considered when preparing the equipment pad, service clearances and outdoor installation location.

Electrical and Refrigerant Connections

This condenser requires a 208/230-volt, single-phase, 60 Hz electrical supply. Rheem lists a minimum circuit ampacity of 27 amps and maximum overcurrent protection of 45 amps. Electrical conductors, disconnects and protective devices must be selected and installed according to the manufacturer’s instructions and applicable electrical codes.

The listed refrigerant connections are 3/8 inch for the liquid line and 7/8 inch for the suction line. Existing line sets must be evaluated for correct diameter, condition, cleanliness and refrigerant compatibility. Never assume an older line set can be reused without inspection and preparation by a licensed technician.

Required Matching Components

The WP14AY48AJ2NA is the outdoor section only. It does not include an indoor air handler, electric heat kit, thermostat, refrigerant line set, equipment pad or installation materials unless those items are specifically shown in the selected package. A compatible air handler and approved metering components are required to create a complete heat pump system.

An optional electric heat kit may provide supplemental or emergency heat when outdoor temperatures are low. The appropriate heat-kit capacity depends on the property’s heating load, electrical service and compatible air-handler model. Always confirm the complete system match before purchase.

Professional Installation Recommended

The WP14AY48AJ2NA must be installed by a qualified HVAC professional familiar with R-454B equipment. Proper evacuation, airflow adjustment, charging, drainage, electrical wiring and system commissioning are essential for safe and reliable performance. Professional installation also helps protect equipment life and warranty eligibility.
