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 dis- tributed across the width of the pan and through a scientifically designed system of outlets. It flows by gravity over the evaporative media. Dry, hot air is moved through the moisture-laden evaporative media where evaporation takes place. The now-humidified air carries moisture in vapor form throughout the home.

The correct water flow is determined by an orifice in each unit. When the unit is operating, there will be a small, steady stream of water to drain, which flushes away most of the trouble-causing minerals. Do not use the saddle valve to regulate the water flow. It is designed to be completely opened or closed.

The minerals and solid residue not trapped by the replaceable evaporative media are flushed down the drain. The drain also eliminates the problems caused by stagnant water. This is the most effective and least expensive method to dispose of trouble-causing minerals.

Trouble-free performance and minimum maintenance are assured by the design features of the Lennox Healthy Climate Humidifier. All unit housing parts that come in contact with water are non-metal and will never rust or corrode. Neither heat nor water will affect them under normal operating conditions.

The evaporative media, designed especially for uniform, high evapora- tion, and the Scale Control Insert also efficiently trap mineral deposits which are often the cause of damage to working parts in ordinary humidifiers. No “white dust” can be distributed throughout the living quarters. The evaporative media must be in good condition to assure high capacity trouble-free perform- ance. It should be changed annually.

The granular coating in the bottom of the distribution tray is designed to provide equal distribution of water to each of the openings assuring an even flow of water over the evaporative media. Do not clean the mineral scale off the bottom of the water distribution tray at the end of the humidification season. The scale provides an excellent track for the water to follow. This is actually what we try to simulate with the synthetic coating in the bottom of the tray. If the coating is removed, it is not necessary to purchase a new distribution tray. You can accomplish the same uniform performance by applying a small amount of liquid dish soap over the entire lower surface of the water distribu- tion tray. This will allow the water to flow evenly through each of the openings.
