your new humidifier can do for you, and what you should do to receive maximum benefits from it. This booklet is intended to answer these questions. The humidifier operates in conjunction with the furnace blower motor. When the humidistat calls for humidity and the blower motor is operating, water flows to the distribution pan located at the top of the unit. The water is uniformly distributed across the width of the pan and through a scientifically designed system of outlets.
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.
IV. Annual Maintenance For best performance, we recommend that you replace the evaporative media in your humidifier annually. • Call the installer of your humidifier. This information is often found on your equipment. V. Annual Summer Shutdown FOR THE SUMMER HUMIDIFIER SHUTDOWN, SIMPLY TURN THE HUMIDISTAT CONTROL TO THE “OFF” SETTING AND CLOSE THE DAMPER IN THE WB2-12 AND WB2-17 MODELS. VI.
