II. Operating Instructions

Your new Lennox Healthy Climate Humidifier is controlled by a manual humidistat installed either in the living area or in the cold air return. It is important to anticipate a drop in temperature and reduce the setting accordingly to avoid excessive condensation. For example, with an outside temperature of 20° the correct setting will be 35% relative humidity. If the temperature is expected to fall to 0° that evening, then reduce the setting to 25% several hours prior to the temperature change.

Be sure to keep fireplace dampers closed when not in use. They provide an excellent escape route for heat, as well as humidity.

The humidistat can be used to determine the relative humidity in your home during the winter. Turn the dial to the lower setting then reverse the dial direc- tion slowly until a “click” is heard. At this point, read the relative humidity on the dial. This will be very close to the actual relative humidity in your home.

To check the humidifier operation, set the humidistat above the click point, make sure that the water saddle valve is open and that there is electricity to the unit. The furnace blower motor must be operating for the humidifier to function. After the humidifier has operated for several minutes and water is entering the unit and coming out at the drain, reduce the humidistat setting below the click point and the unit should automatically shut off. Now, set the humidistat dial at the recommended inside relative humidity, depending on the outside tempera- ture. Follow the suggested settings prior to a drop in the outside temperature.

III. Effect of Water Characteristics

Your humidifier will operate effectively using either hard or mechanically softened water.

Any type of water (hard, soft, hot, or cold) is acceptable for use with the WB2 or WP2 drain-type humidifiers. Hot supply water, 140° maximum, is rec- ommended for all heat pump applications. The use of hot supply water will also increase the unit’s capacity in other applications.
