Aprilaire Annual Maintenance For The 500 Humidifier 

This video shows you step by step how to perform the seasonal maintenance on your Aprilaire 500 Bypass Whole Home Humidifier. HVAC.com discusses how to check the water feed tube, the strainer, the drain tube, the drain spud, the orifice, and the water panel. All of these are important parts that ensure your humidifiers performance and efficiency.
This maintenance should be performed once a year, typically before your humidifier season begins so it is ready once you need to use it. Some prefer to do the maintenance right after the humidifier season is complete, it is totally up to your personal preference!
