To shut off your Aprilaire humidifier, simply adjust its control dial to the "Off" position, ensuring the solenoid valve is fully disengaged to prevent unwanted operation.
Step-by-Step Guide to Shutting Down Your Humidifier
Properly shutting off your Aprilaire humidifier is crucial for seasonal maintenance, energy saving, and preventing unnecessary water usage when humidification is not needed. Follow these steps to ensure it is completely turned off:
- Locate the Humidifier Control Dial: This dial is typically found on the humidifier unit itself or on a wall-mounted control (humidistat) near your thermostat.
- Turn to the "Off" Position: Rotate the control dial setting to the marked “Off” position. This is the initial step to disable the unit.
- Calibrate the "Off" Point (Advanced Check):
- Slowly turn the dial clockwise from the "Off" position until you hear the solenoid valve on the humidifier "click on." This click indicates the valve has opened, allowing water to flow.
- Next, slowly turn the dial counter-clockwise from this point until you hear the solenoid valve "click off." This ensures the valve is fully closed and no water will flow to the humidifier. This position represents the true, complete "Off" point for your system.
- Confirm Power Status (Optional): For complete peace of mind, you can also switch off the dedicated power supply to the humidifier at your furnace or electrical panel, especially when preparing for extended periods of non-use.
Why Shut Off Your Humidifier?
There are several reasons why you might need to turn off your Aprilaire humidifier:
- Seasonal Changes: As temperatures rise and natural humidity increases in spring and summer, operating a humidifier becomes unnecessary and can even lead to excess moisture issues in your home.
- Maintenance: Before performing any maintenance, such as cleaning or replacing the water panel (filter), the humidifier should always be turned off to ensure safety and prevent water leaks.
- Troubleshooting: If you are experiencing issues with your humidifier, turning it off can be the first step in diagnosing the problem.
- Preventing Over-Humidification: In climates or seasons where the indoor humidity is already sufficient, keeping the humidifier off helps avoid potential problems like mold, mildew, or condensation on windows.
Verifying Your Humidifier is Off
The "click off" method described in step 3 above is the most reliable way to confirm that the humidifier's water supply (controlled by the solenoid valve) is completely disengaged. This precise adjustment ensures that the system isn't inadvertently drawing water or attempting to operate when you intend it to be dormant.
Essential Tips for Humidifier Maintenance
Turning off your humidifier often coincides with preparing it for storage or seasonal shutdown. Here’s a quick maintenance checklist:
| Task | Description | Frequency (Approx.) |
|---|---|---|
| Replace Water Panel (Filter) | A clean water panel is crucial for efficient operation and air quality. Install a new one at the start of each heating season or when shutting down for the summer. | Annually |
| Clean the Humidifier Unit | Remove mineral deposits and debris from the humidifier tray, distribution tray, and drain tube. Use a mild soap and water solution or vinegar for stubborn buildup. | Annually |
| Check Water Line & Drain | Inspect the water supply line for leaks and ensure the drain line is clear and free of obstructions to prevent overflow. | Annually |
| Turn Off Water Supply | Locate the saddle valve on your cold water line and turn it clockwise to close off the water supply to the humidifier, especially for extended shutdowns. | Seasonally |
| Turn Off Power | Switch off the dedicated power to the humidifier at the furnace control board or electrical panel to fully disable the unit and prevent accidental startup. | Seasonally |
When to Turn It Off for the Season
Most homeowners turn off their Aprilaire humidifiers around late spring or early summer, typically when outdoor temperatures consistently stay above 60°F (15°C) and indoor humidity levels remain comfortable without assistance. Monitor your indoor humidity with a hygrometer; if it's consistently above 40-50% relative humidity, it's a good time to shut down your humidifier for the season.
