GeneralAire 1042LH Legacy Humidifier Instruction Manual

1. Produkt överview

The GeneralAire 1042LH Legacy Humidifier is a furnace-mounted, bypass-type humidifier designed to introduce moisture into your home's air. It operates by dispersing water evenly across a vapor pad. A portion of the heated air from your furnace passes through this water-soaked pad, absorbing moisture before being distributed throughout your living space. This process helps maintain optimal humidity levels for improved comfort and air quality.

The GeneralAire 1042LH operates manually via the included duct-mounted humidistat. Once installed and connected, the humidifier will activate when the humidistat senses that the humidity level in your home is below the set point and the furnace fan is operating.

4.1 Inställning av hygrostat

1. Locate the manual-control duct mount humidistat.
2. Turn the dial to your desired humidity level. A common starting point is 35-40% relative humidity.
3. Monitor your home's humidity and adjust the humidistat as needed for comfort.
4. During extremely cold weather, it may be necessary to lower the humidistat setting to prevent condensation on windows.

When the humidistat calls for humidity, water flows to the distribution tray at the top of the humidifier, saturating the humidifier pad. As warm air from the furnace passes through the wet pad, it picks up moisture and distributes it throughout your home.
