The humidifier operates in conjunction with the furnace blower motor. When the humidifier control calls for humidity and the blower motor is operating, water flows to the distribution tray located at the top of the humidifier. The water is uniformly distributed across the width of the tray and through a scientifically designed system of outlets. It flows by gravity over the humidifier pad. Dry, hot air is moved through the moisture-laden humidifier pad 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 humidifier. When the humidifier 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 humidifier pad 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 humidifier. All humidifier housing parts that come in contact with water are non-metal (except for the valve and humidifier pad) and will never rust or corrode. Neither heat nor water will affect them under normal operating conditions.

The humidifier pad, designed especially for uniform, high evaporation, 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 humidifier pad must be in good condition to assure high capacity trouble-free performance. It should be changed annually.

Older design water distribution trays have a granular coating in the bottom of the distribution tray to provide equal distribution of water to each of the openings assuring an even flow over the humidifier pad. Do

not clean the mineral scale off the bottom of the water distribution tray at the end of the humidification season. If the granular 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 dishwashing soap over the entire inside surface of the water distribution tray. This will allow the water to flow evenly through each of the openings, provided the humidifier is level, in order to achieve maximum capacity.

The current distribution tray which incorporates a synthetic fabric liner that replaces the granular coating, is designed to deliver water uniformly over the entire top surface of the humidifier pad, provided it is mounted level. It is normal for some mineral deposits to form in the distribution tray as it dries out between humidification cycles. These deposits can actually help distribute water in the tray, but if they form enough to block the openings, they should be removed as described in the “Periodic Preventative Maintenance” section of this manual.
