Operation
The GeneralAire 990-13 Water Pad functions as the primary evaporative surface within your humidifier. Once installed, the humidifier's system will automatically draw water onto the pad, and air will pass through it, facilitating the evaporation process and adding humidity to your indoor environment. No direct user interaction with the pad is required during operation.
Maintenance and Replacement
Regular replacement of the water pad is crucial for maintaining your humidifier's efficiency and ensuring optimal humidity output.
- For optimum performance, it is recommended to replace the filter twice per heating season.
- At a minimum, change the water pad annually.
Failure to replace the water pad as recommended can lead to reduced humidification efficiency, increased energy consumption, and potential mineral buildup within the humidifier unit.

Troubleshooting
If you experience reduced humidity output from your GeneralAire humidifier after installing a new water pad, consider the following:
- Incorrect Installation: Ensure the water pad is correctly seated within its housing and that all humidifier components are properly reassembled.
- Water Supply: Verify that the humidifier is receiving an adequate water supply and that the water distribution system is functioning correctly.
- Humidistat Settings: Check your humidistat settings to ensure it is set to an appropriate humidity level for your home.
- Airflow: Confirm that there is proper airflow through the humidifier. Blockages can impede evaporation.
- Pad Condition: If the pad is old or heavily scaled, replace it according to the maintenance schedule.
For persistent issues, consult your GeneralAire humidifier's main instruction manual or contact GeneralAire customer support.
