Installation Process
Begin with unboxing and component verification, then carefully select the appropriate installation location – either the supply plenum or return air duct.
Unboxing and Component Check
Carefully unpack the Aprilaire 700 humidifier, ensuring all components are present and undamaged. The package should include the humidifier unit itself, the water panel, mounting hardware (screws, brackets), and potentially adapter/filler plates.
Inspect the unit for any shipping damage, such as dents or cracks. Verify the presence of the control system components if included in your package. A thorough check at this stage prevents delays later.
Compare the contents against the parts list in this manual. Handle all parts with care to avoid damage. Retain the packaging materials for potential returns or warranty claims. Proper component verification is crucial before proceeding with the installation process.
Choosing the Installation Location (Supply Plenum vs. Return Air)
The Aprilaire 700 and 700M models offer flexibility in installation, accommodating either the supply plenum or return air duct. Supply plenum installation delivers slightly cooler, more consistent humidity, while return air installation is often simpler.
Consider ductwork configuration and airflow when deciding. The Model 700 isn’t suitable for horizontal airflow ducts, impacting performance. Ensure adequate space around the chosen location for maintenance access.
Evaluate the proximity to a water supply and drain. Return air installations generally require longer water lines. Carefully assess your HVAC system and home layout to determine the most practical and efficient location for optimal humidifier operation.
Ductwork Considerations & Airflow Requirements
Proper ductwork preparation is crucial for optimal Aprilaire 700 performance. Ensure sufficient space is available for the unit and future maintenance access. Avoid installing on ducts with horizontal airflow, as this significantly reduces efficiency.
The ductwork must be robust enough to support the humidifier’s weight. Reinforcement may be necessary. Verify adequate airflow across the evaporator pad; restricted airflow diminishes humidification capacity.
Consider duct size and shape when planning the installation. Consult the installation manual for specific airflow recommendations. Proper sealing of all connections prevents air leaks and maximizes system efficiency.
Mounting the Humidifier Unit
Securely mounting the Aprilaire 700 is essential for stable operation and longevity. Utilize the provided mounting hardware, ensuring it’s appropriate for the ductwork material. The unit can be installed on either the supply or return plenum, based on your system’s configuration.
Carefully align the humidifier with the duct opening, ensuring a tight seal to prevent air bypass. Use adapter plates, if necessary, to accommodate different duct sizes.
Double-check the unit’s levelness before fully tightening the mounting screws. A level installation promotes even water distribution and optimal performance. Handle with care during mounting to avoid damaging components.
Electrical Connections
Proper electrical connections are vital for safe operation. Always disconnect power before wiring, and follow the detailed wiring diagram provided in the manual.
Wiring Diagram Overview
The Aprilaire 700 wiring diagram illustrates the connections between the humidifier, the HVAC system, and the power source. Carefully review this diagram before commencing any electrical work. It details the necessary wiring for both standard and high-voltage systems, clearly indicating the placement of wires for the transformer, control board, and power supply.
Pay close attention to the color-coding of the wires and ensure correct connections to avoid electrical hazards or system malfunctions. The diagram also specifies the required wire gauge for optimal performance and safety. Refer to the humidifier control safety and installation instructions for detailed wiring guidance. Always prioritize electrical safety by shutting off power at the disconnect switch or service panel before making any connections.
Shutting Off Power & Electrical Safety
Prior to any electrical work on the Aprilaire 700, completely disconnect power at the unit’s disconnect switch or the main service panel. This is a critical safety precaution to prevent electrical shock and potential damage to the humidifier or your HVAC system. Verify the power is off using a non-contact voltage tester before proceeding.
Always adhere to local electrical codes and regulations during installation. If you are uncomfortable working with electrical wiring, consult a qualified HVAC professional. Improper wiring can create a fire hazard or void the warranty. Remember to remove the front panel to access adapter and filler plates with screws, but only after confirming power is safely disconnected.
Connecting the Humidifier to the Power Source
Refer to the wiring diagram (found in the humidifier control safety and installation instructions) for detailed guidance on connecting the Aprilaire 700 to your power source. Ensure all connections are secure and comply with local electrical codes. Typically, this involves connecting the humidifier’s wiring to the appropriate terminals on your HVAC system’s control board.
Double-check the wiring configuration before restoring power. Incorrect wiring can damage the humidifier or your HVAC system. Once connections are verified, carefully restore power at the disconnect switch or service panel. After power restoration, proceed with system checkout procedures to confirm proper operation and functionality of the newly installed humidifier.
Water Supply & Drainage
Proper water line connection and drainage are crucial for Aprilaire 700 operation; options include direct connection and condensate drain installation for efficient performance.
Connecting the Water Supply Line
Establishing a reliable water supply is paramount for your Aprilaire 700 humidifier. Locate a cold water line nearby, ideally within four feet of the unit, to minimize potential issues. A shut-off valve is essential for easy maintenance and water panel replacement.
Use a saddle valve or a tee fitting to tap into the water line; saddle valves are simpler to install, but tee fittings offer a more secure and permanent connection. Ensure the connection is leak-proof using Teflon tape on threaded fittings.
The water supply line should be ½ inch copper or PEX tubing. Avoid using plastic tubing as it may become brittle over time. Properly secure the tubing to prevent kinks or sags, ensuring consistent water flow to the humidifier. Always check for leaks after installation!
Drainage Options and Installation
Proper drainage is crucial to prevent water damage and maintain optimal humidifier function. The Aprilaire 700 offers several drainage options, including a floor drain, a condensate pump, or connection to an existing drain line.
If a floor drain is available, ensure it’s lower than the humidifier’s drain outlet and install a trap to prevent sewer gases from entering your home. A condensate pump is ideal when a floor drain isn’t accessible; select a pump rated for the humidifier’s drainage volume.
Securely connect the drain line using appropriate fittings and slope it downwards to facilitate drainage. Regularly inspect the drain line for clogs or obstructions to ensure proper operation and prevent overflow.
Water Panel Inspection and Maintenance
Regular inspection of the water panel is vital for maintaining humidifier efficiency and preventing scale buildup. The Aprilaire 700 utilizes a disposable water panel that requires periodic replacement, typically every season, depending on water quality.
Visually inspect the panel monthly for mineral deposits or discoloration. Excessive buildup reduces evaporation and airflow. While cleaning is not recommended, monitoring the panel’s condition helps determine replacement frequency.
Always turn off the water supply before removing or replacing the water panel. Follow the manufacturer’s instructions for proper installation of the new panel, ensuring a snug fit. Consistent water panel maintenance ensures clean, healthy humidification.
