The Basics of Janitrol Air Handler Wiring Diagrams

The installation and maintenance of an air-conditioning system is highly specialized work, and it requires a clear understanding of how to read wiring diagrams. A wiring diagram, also known as a schematic, specifies the points of connection between various components inside a system, and provides a clear understanding of how the parts are connected. Knowing how to read a wiring diagram can make all the difference when it comes to completing any project correctly and safely.

Janitrol is a leading manufacturer of heating, ventilating, and air conditioning systems for residential and commercial applications. When installing a Janitrol air-conditioning system, it is critical to understand and follow the product's wiring diagram. In this article, we will explore the basics of Janitrol air handler wiring diagrams, and highlight a few key areas to consider when connecting different components.

Identifying Component Endpoints and Connectors

Before starting to connect the wiring diagram, a technician must first identify all component endpoints. These are the connection points that the wires attach to in order to complete the circuit. Once these are identified, any existing terminal blocks and connectors can be connected by referencing the diagram as a guide. If any matching terminals or connectors cannot be identified, they should be replaced with new ones before proceeding.

Ensuring Correct Voltage Is Applied

Incorrect voltage can cause severe damage to the air-conditioning unit and its components. Before connecting any components it is important to check that the specified voltage is provided to the unit. The diagram should clearly indicate which wire must be grounded and which must be energized. It is also essential to check the maximum current draw the unit can withstand, and ensure that it is not exceeded.

Understanding Electrical Symbols

A wiring diagram should use standard electrical symbols to represent each various component, including the resistors, capacitors, relays, transformers, etc. Understanding these symbols is essential when reading a Janitrol air handler wiring diagram. Typically to identify the various components in a circuit, several lines will be drawn to form a series or parallel connection.

Double-checking Connections

Once all the connections have been made, it is essential to double-check them. This includes ensuring that all components and wires are properly connected, as well as ensuring that all circuits are running at optimal voltage. By checking the connections regularly, any faults or incorrect wiring can quickly be identified and repaired.

Following these basic steps, a technician can successfully identify and install a Janitrol air handler wiring diagram. By being familiar with the diagrams, the technician can safely and accurately complete any job.
