Rheem air handlers serve as the backbone of many air distribution systems throughout the world. When you wire a Rheem air handler according to manufacturer specifications and local codes, expect years of dependable service backed by over 70 years of manufacturing experience. You can install and wire Rheem air handlers in attics and crawlspaces, closets, utility rooms, garages and basements. Once wired and complete, your Rheem air handler can host standard air conditioners, heat pumps and geothermal units. It also can host electric heat elements and control humidification and indoor air quality, such as filtration and make-up air (air brought into a building through ventilating).
Things You'll Need
- Wire strippers
Connect one hot leg from your electrical service panel to the L1 terminal in your Rheem air handler. Inside the control box, locate the contactor by finding a square, dark plastic object with two screw terminals marked L1 and L2.
Connect the second hot leg from your electrical service panel to the L2 terminal in your Rheem air handler. Tighten both L1 and L2 securely, being careful not to strip the threads.
Connect the ground wire from your electrical service panel to the ground lug inside your Rheem air handler. Inside the control box locate the ground lug near the contactor by finding a square, cast aluminum block with a green screw terminal. Tighten the ground securely.
Connect your thermostat wires to the Rheem air handler's main circuit board. Color coding and terminal designation will depend on your specific thermostat, the heating and cooling system installed, such as heat pump, geothermal and electric heat. Common thermostat designations include "R" for power to the thermostat, "W" for the heating system, "Y" for the cooling system, and "G" for indoor fan control.
