In addition to tools, you will also require some essential materials․ These include wiring for electrical connections, water tubing for the water supply and drain lines, pipe clamps, and possibly some sheet metal screws or foil tape for securing the humidifier to the ductwork․ A voltage tester is highly recommended to ensure safe electrical connections․
Having all these tools and materials readily available will save time and prevent interruptions during the installation process, ensuring a smoother and more efficient experience․
Installation Options and Placement
Selecting the correct location for your Aprilaire 700 humidifier is crucial; Consider supply versus return placement and proximity to cooling coils to optimize performance and prevent potential issues․
Choosing the Optimal Location: Supply vs․ Return
The Aprilaire 700 humidifier can be installed on either the supply or return duct of your HVAC system․ The choice depends on your specific setup and preferences․ Installing on the supply duct allows humidified air to be directly distributed throughout the home․ This method typically requires a bypass duct connection․
Return duct installation draws air from the return side, humidifies it, and then introduces it into the supply side․ Consider the available space and accessibility when making your decision․ Ensure proper airflow and avoid obstructions for optimal humidifier performance․ Careful planning is key for efficient humidification․
Installation Near Cooling Coils
When installing the Aprilaire 700 in relation to cooling coils, it is crucial to position the humidifier correctly to prevent potential issues․ The recommended approach is to install the humidifier before the cooling coils in the warm air plenum․ This placement ensures that the humidified air is properly conditioned before reaching the cooling system․
Avoid installing the humidifier after the cooling coils, as this can lead to condensation and reduced efficiency; Proper placement in relation to the cooling coils is critical for maintaining optimal performance and preventing damage to your HVAC system․ Always consult the installation manual for specific diagrams and instructions․
Electrical Connections
This section details the electrical wiring for the Aprilaire 700, including the wiring diagram, transformer information, and proper connection to a power source, ensuring safe and efficient operation․
Wiring Diagram and Transformer Information
Understanding the wiring diagram is crucial for a successful Aprilaire 700 installation․ The diagram illustrates the proper connections between the humidifier, the HVAC system, and the power source․ The Aprilaire 700 typically includes a transformer to step down the voltage to a safe level for the humidifier’s operation․
It’s essential to identify the primary and secondary circuits of the transformer and avoid improper wiring․ The wiring instructions on the humidifier control should be reviewed․ Incorrect wiring can damage the humidifier or the HVAC system․ Refer to the provided diagrams for safe and effective electrical connections․
Connecting to Power Source
Connecting the Aprilaire 700 to a power source requires careful attention to detail to ensure safe and reliable operation․ The humidifier typically uses a low-voltage transformer, and the wiring must comply with local electrical codes․ Before making any electrical connections, turn off the power to the HVAC system at the breaker box․
Identify the appropriate terminals on the transformer and connect the wires according to the wiring diagram․ Ensure that all connections are secure and properly insulated․ Use wire connectors or caps to prevent accidental shorts or loose connections․ Once the wiring is complete, restore power to the HVAC system and verify the humidifier receives power․
Plumbing Installation
Proper plumbing is crucial for the Aprilaire 700’s operation․ This involves connecting a water supply and setting up a drain line to manage excess water․ Follow these steps for a successful plumbing installation․
Water Supply Connection (Hot or Cold)
Connecting the Aprilaire 700 to a water supply is a key step․ You have the option to use either a hot or cold water line, depending on your preference and local water conditions․ Ensure the water supply is turned off before beginning any plumbing work․
Use a saddle valve or a suitable fitting to tap into the chosen water line․ Connect the humidifier’s water inlet to this fitting, ensuring a tight, leak-free connection․ Follow the manufacturer’s instructions for the specific type of connection required․ Regardless of your selection, regularly inspect the connection for leaks․
Drain Line Setup
Proper drain line setup is crucial for the Aprilaire 700 to function correctly, preventing water damage and ensuring efficient operation․ The drain line carries away excess water from the humidifier․ Select a suitable location for the drain, ideally a floor drain or a utility sink, ensuring the drain line has a continuous downward slope for gravity to work․
Connect the drain line securely to the humidifier’s drain fitting․ Use appropriate tubing and fittings to create a reliable, leak-proof connection․ Avoid sharp bends or kinks in the drain line, as these can restrict water flow and cause backups․ Secure the drain line to prevent accidental disconnections․
Final Checks and Operation
After installation, leveling the humidifier is vital․ Then comes testing to ensure proper functionality․ Troubleshooting common issues completes the process, guaranteeing optimal performance and a comfortable home environment․
Leveling the Humidifier
Ensuring your Aprilaire 700 humidifier is perfectly level is crucial for optimal performance․ An unlevel unit can lead to uneven water distribution, potentially causing mineral buildup and reducing the humidifier’s efficiency․ Use a level to check the unit’s horizontal alignment on the duct․
Adjust the mounting brackets as needed until the bubble on the level is centered․ A level humidifier ensures that water flows evenly across the water panel, maximizing evaporation and humidity output․ Double-check the leveling after securing all mounting screws to guarantee stability and prevent future issues․ This small step significantly contributes to the humidifier’s longevity and effectiveness in maintaining healthy humidity levels in your home․
A properly leveled unit also prevents water leakage and ensures quiet operation, ultimately enhancing your overall comfort․
Testing and Troubleshooting
After installation, thoroughly test the Aprilaire 700 to ensure proper operation․ Turn on the furnace and humidifier, verifying that water flows to the distribution tray and the fan is running smoothly․ Check for any leaks around the water connections and drain line․ If the humidifier doesn’t activate, examine the wiring and humidistat settings․
Consult the wiring diagram to confirm correct connections․ If water isn’t flowing, inspect the water supply valve and solenoid valve for obstructions․ Listen for any unusual noises, which could indicate a mechanical issue․ Refer to the Aprilaire 700 installation manual for detailed troubleshooting steps and error codes․ Resolving any issues promptly ensures efficient and reliable humidity control for your home․
Remember to regularly inspect the humidifier’s performance to maintain optimal indoor air quality․
