Four-Way Convertible Design

The Rheem Select 3 Ton Air Handler offers a versatile four-way convertible configuration. Depending on the approved application, it can support upflow, downflow, horizontal-left, or horizontal-right installation.

This multiposition design provides installation flexibility while the compact 17.5-inch cabinet helps the unit fit within qualifying residential HVAC spaces. The final orientation must follow the applicable product instructions and drainage requirements.

Aluminum Indoor N-Coil

The indoor N-Coil is constructed with aluminum fins bonded to internally grooved aluminum tubing. This aluminum design supports dependable heat transfer and provides improved corrosion resistance in qualifying indoor environments.

The factory-installed thermal expansion valve regulates refrigerant flow in compatible R-454B cooling and heat pump systems. Final system efficiency and performance depend on the complete approved equipment combination.

Integrated Refrigerant Detection System

The Rheem Select 3 Ton Air Handler includes the PlusOne® Refrigerant Detection System™, which combines an A2L sensor and mitigation board in an integrated design.

If excess refrigerant is detected, the system is designed to pause outdoor unit operation as part of its mitigation response. The integrated configuration also supports simplified wiring and compatibility with qualifying 24V thermostat applications.

Optional Electric Heater Kits

Compatible field-installed auxiliary electric heater kits are available separately. These kits can provide supplemental electric heat and may include circuit breakers that meet applicable UL and cUL service-disconnect requirements.

The correct heater kit must be selected according to the air handler model, electrical service, heating requirements, circuit protection, and applicable local codes.

Verify Equipment Compatibility

The Rheem Select 3 Ton Air Handler must be properly matched with a compatible outdoor air conditioner or heat pump, thermostat, refrigerant line set, electrical components, and optional heat kit.

Do not select an air handler based only on nominal tonnage or cabinet width. A qualified HVAC professional should verify the approved equipment combination, available AHRI rating, refrigerant requirements, airflow settings, voltage, and installation orientation before ordering.

Professional Installation Required

Installation must be performed by a qualified HVAC professional according to manufacturer instructions and applicable regulations. The installer should verify electrical service, refrigerant connections, condensate drainage, airflow configuration, A2L sensor operation, thermostat compatibility, and complete system performance.
