Get rid of crawl space moisture: step-by-step guide to installing an aprilaire dehumidifier

Excess moisture in your crawl space can lead to a myriad of problems, including mold growth, wood rot, and musty odors. An Aprilaire dehumidifier is an effective solution to control humidity levels and improve the health and comfort of your home. This comprehensive guide will provide step-by-step instructions on how to install an Aprilaire dehumidifier in your crawl space, ensuring optimal performance and lasting benefits.

Materials Required

• Aprilaire dehumidifier
• Ductwork (flexible or rigid)
• Duct connectors
• Duct tape
• Electrical wire
• Electrical connectors
• Voltage tester
• Drill
• Screwdriver
• Level
• Safety glasses

Safety Precautions

Before starting any installation work, it is crucial to follow these safety precautions:

• Wear safety glasses to protect your eyes from debris.
• Ensure the electrical power is turned off at the main breaker panel.
• Use a voltage tester to verify that the power is indeed off before touching any electrical wires.

Step 1: Choose an Installation Location

Select a location in the crawl space that is central and has sufficient space for the dehumidifier. Avoid placing the unit near heat sources or areas with excessive moisture.

Step 2: Mount the Dehumidifier

Level the dehumidifier using shims or a level. Secure it to the floor joists or subfloor using screws or bolts.

Step 3: Connect the Ductwork

Attach the ductwork to the inlet and outlet openings of the dehumidifier. Use duct connectors and duct tape to ensure a secure and airtight connection.

Step 4: Run the Electrical Wiring

Run electrical wire from the electrical panel to the dehumidifier. Connect the wire to the electrical terminals of the dehumidifier according to the manufacturer’s instructions.

Step 5: Test the Electrical Connections

Turn on the electrical power at the main breaker panel. Use a voltage tester to verify that the dehumidifier is receiving power.

Step 6: Install the Condensate Drain

Connect a condensate drain hose to the drain outlet of the dehumidifier. Route the hose to a suitable drain location, such as a sump pump or a floor drain.

Step 7: Level the Dehumidifier

Once the dehumidifier is connected, level it again to ensure proper drainage.

Troubleshooting Common Issues

• Dehumidifier not working: Check the electrical connections, power supply, and condensate drain for any issues.
• Insufficient dehumidification: Ensure the dehumidifier is sized appropriately for the crawl space and that the ductwork is not obstructed.
• Excessive noise: Check if the dehumidifier is level and that the ductwork is properly installed.
