An air handler is an important part of your HVAC system. It is responsible for circulating the air in your home, and is responsible for the heating and cooling of your home. If you’re planning on installing a 15KW air handler, then you will require a wiring diagram. In this article, we will discuss the 15KW air handler wiring diagram, so that you can understand it better and install it with ease.
What is a 15KW Air Handler?
A 15KW air handler is an HVAC system that can provide up to 15,000 watts of power. It is used to circulate air around your home and is usually installed in large homes or commercial buildings. The 15KW air handler is designed to handle more air and to heat or cool your home more efficiently than smaller units.
Wiring Diagram for 15KW Air Handler
A wiring diagram is a detailed schematic that shows the wiring connections of an electrical system. When installing a 15KW air handler, it is important to follow the wiring diagram to ensure everything is connected correctly. Below is a wiring diagram for the 15KW air handler:
| Wiring Connection | Wire Color | Terminal Location |
|---|---|---|
| Power Supply | Black | L1 |
| Power Supply | White | L2 |
| Ground | Green/Yellow | GRND |
| Transformer | Black | TR1 |
| Transformer | White | TR2 |
| Circuit Board | Red | R |
| Circuit Board | Blue | C |
| Heating Element | Orange | W1 |
| Fan Motor | Black | L1 |
| Fan Motor | Blue | L2 |
Power Supply Connections
The power supply connections are the first connections that should be made. The black wire should be connected to terminal L1, and the white wire should be connected to terminal L2. It is important to ensure that the power supply is connected correctly, as this can be dangerous if done incorrectly.
Once the power supply is connected, the next step is to connect the ground wire. The ground wire is usually green or green/yellow and should be connected to the GRND terminal.
Transformer Connections
The transformer connections are the next connections that should be made. The black wire should be connected to terminal TR1, and the white wire should be connected to terminal TR2. The transformer is responsible for converting the voltage from the power supply to the voltage required by the circuit board.
Circuit Board Connections
The circuit board connections are the next connections that should be made. The red wire should be connected to terminal R, and the blue wire should be connected to terminal C. The circuit board is responsible for controlling the fan motor and heating element.
Heating Element and Fan Motor Connections
Finally, the heating element and fan motor connections should be made. The orange wire should be connected to terminal W1, and the black wire should be connected to terminal L1. The blue wire should be connected to terminal L2. The heating element is responsible for heating the air, and the fan motor is responsible for circulating the air around your home.
