Safety Precautions Before Installation

Prior to commencing installation, ensure the furnace and any associated electrical components are completely de-energized at the breaker panel. This crucial step prevents electrical shock and ensures a safe working environment. Always verify the power is off with a reliable voltage tester.

Exercise caution when working with water lines; proper connection is vital to avoid leaks and potential water damage. If unfamiliar with plumbing or electrical work, professional installation is strongly advised. Wear appropriate safety glasses and gloves during the process. Review all wiring diagrams carefully before making any connections, and adhere to local electrical codes.

Installation Process

The installation involves securing necessary tools, identifying a suitable location near the furnace, and carefully connecting the humidifier to both water and airflow systems.

Tools Required for Installation

Before commencing the Aprilaire 700 installation, gather essential tools for a smooth process. A screwdriver set – both Phillips and flathead – is crucial for various mounting and connection tasks. You’ll also need adjustable pliers to securely tighten fittings on the water supply line.

A drill with appropriate drill bits is necessary for creating mounting holes, ensuring a stable installation. A level will guarantee the unit is properly aligned. Wire strippers and connectors are vital for safe and effective electrical wiring. Don’t forget a pipe cutter for precise water line adjustments, and Teflon tape to prevent leaks. Finally, safety glasses are paramount for eye protection throughout the installation.

Locating the Ideal Installation Spot

The Aprilaire 700 humidifier is optimally installed within the cold air return ductwork of your forced-air heating system. Choose a location that allows for sufficient space around the unit for maintenance and filter changes. Ensure the chosen spot is accessible for future servicing.

Avoid areas prone to freezing temperatures, as this can damage the humidifier. Proximity to a suitable water supply line is essential to minimize plumbing work. Consider the airflow direction to ensure efficient moisture distribution throughout your home. A straight duct section is preferable, avoiding sharp bends that could restrict airflow. Prioritize a stable, secure mounting surface.

Connecting to the Furnace

Proper connection to your furnace is crucial for the Aprilaire 700’s operation. The humidifier integrates into the cold air return duct, utilizing the furnace’s blower to distribute moisture. Ensure compatibility with your blower and fan coil unit; consult the unit’s specifications for appropriate airflow ranges.

Securely mount the humidifier to the ductwork, ensuring a tight seal to prevent air leaks. The connection should not obstruct airflow significantly. Verify the furnace’s electrical system can support the humidifier’s power requirements. Follow all local codes and regulations during the connection process. Professional installation is always recommended for optimal performance and safety.

Blower and Fan Coil Unit Compatibility

The Aprilaire 700 humidifier functions optimally with a wide range of blower and fan coil units, but verifying compatibility is essential. Ensure your system delivers sufficient static pressure for effective moisture distribution throughout your home. Insufficient airflow can hinder the humidifier’s performance, leading to uneven humidity levels.

Consult your furnace or fan coil unit’s documentation to confirm its airflow capacity meets the Aprilaire 700’s requirements. Improperly matched systems may require adjustments or upgrades. Professional HVAC technicians can assess your existing setup and recommend necessary modifications for seamless integration and efficient operation.

Water Supply Connection

Establishing a reliable water supply is crucial for the Aprilaire 700’s functionality. A direct connection to a cold water line, typically ½ inch in diameter, is required. Ensure the water line is accessible and positioned to facilitate easy connection to the humidifier unit. A shut-off valve should be installed upstream of the humidifier to allow for maintenance and prevent water damage.

Properly sized tubing and fittings are essential to prevent leaks and maintain consistent water flow. Avoid using compression fittings, opting instead for threaded connections with Teflon tape for a watertight seal. Always check for leaks after connecting the water line and before powering on the humidifier.

Connecting to the Water Line

To connect to the water line, first shut off the water supply at the nearest valve. Carefully drill a ½ inch hole into the cold water pipe, ensuring it’s a safe distance from any electrical wiring or other utilities. Install a saddle valve or a tee fitting with a shut-off valve to the cold water line.

Attach the provided tubing from the humidifier to the outlet of the shut-off valve, securing it with appropriate fittings. Double-check all connections for tightness and apply Teflon tape to threaded joints to prevent leaks. Slowly turn the water supply back on and inspect for any drips or signs of water escaping.

Humidifier Unit Mounting

Securely mount the Aprilaire 700 humidifier unit directly to the ductwork, ensuring it’s positioned for optimal airflow and easy access for maintenance. Use self-tapping screws appropriate for the duct material, and verify the unit is level to prevent water pooling.

Confirm sufficient clearance around the unit for filter changes and servicing. The unit should be mounted with the water supply connection facing downwards to minimize potential leaks. Properly support the weight of the humidifier to avoid stressing the ductwork.

Electrical Wiring

Proper electrical connections are crucial; consult the wiring diagram for safe and effective power supply integration, including essential grounding instructions.

Wiring Diagram Overview

Understanding the wiring diagram is paramount for a successful Aprilaire 700 installation. The diagram illustrates the recommended method for detecting furnace operation, ensuring seamless integration with your existing HVAC system.

Maintenance and Care

Regular filter replacement and humidifier unit cleaning are crucial for optimal performance. Winterization procedures should be followed to prevent damage during colder months.

Regular Filter Replacement

Maintaining optimal performance of your Aprilaire 700 humidifier hinges on consistent filter replacement. The frequency depends on your home’s air quality and usage, but generally, filters should be checked monthly during the heating season. A clogged filter restricts airflow, diminishing humidification efficiency and potentially causing system strain.

Aprilaire recommends replacing the evaporative pad annually for peak performance. Inspect the pad for mineral buildup or discoloration, indicating it’s time for a change. Replacement is straightforward; consult the installation manual for detailed instructions. Utilizing genuine Aprilaire replacement filters ensures compatibility and maintains the humidifier’s warranty. Ignoring filter maintenance can lead to reduced humidity levels and increased energy consumption.

Cleaning the Humidifier Unit

Regular cleaning of your Aprilaire 700 humidifier is crucial for preventing mineral buildup and maintaining hygienic operation. Before cleaning, always disconnect the power supply to avoid electrical hazards. The humidifier’s water panel and reservoir should be inspected and cleaned at least annually, or more frequently in areas with hard water.

Use a mild cleaning solution, like vinegar diluted with water, to remove scale and deposits. Avoid abrasive cleaners that could damage the unit’s components. Rinse thoroughly with clean water after cleaning. Inspect the drain line for clogs and flush it with water to ensure proper drainage. A clean humidifier operates more efficiently and delivers healthier air.

Winterization Procedures

Preparing your Aprilaire 700 for the off-season is vital to prevent damage from freezing temperatures and ensure smooth operation next heating season. Before extended periods of non-use, completely drain the humidifier unit and water supply lines. Disconnect the water supply to prevent accidental refills and potential freezing.

Remove the water panel for thorough drying and storage in a clean, dry location. Consider applying a small amount of mineral oil to the panel to prevent drying and cracking. Power off the humidifier at the breaker and ensure all electrical connections are secure. Proper winterization safeguards your investment and extends the humidifier’s lifespan.
