[. . . ] Since every degree of temperature setback represents about 3% of your heating costs, this can possibly represent a significant annual savings. During the heating season, cold air is brought into the home and heated. When heated, this air dries out and greatly increases its capacity to hold more moisture. By using a humidifier, a source of water is provided to satisfy this increased moisture holding capability, rather than having it drawn from our body surface and the surrounding hygroscopic furnishings in the home. 1 Specifications To improve the efficiency of your humidifier, and to reduce the possibility of a health hazard, it is recommended that you take the following precautions: · Follow the manufacturer's recommended cleaning and maintenance instructions.

The necessity to clean your humidifier is substantially the result of impurities coming in through your water supply, which feeds the humidifier. Other household dust, containing biological and microbial contaminants, finds its way into the air handling system and ultimately, the humidifier. The humidifier is not the source of these impurities. To enjoy the benefits of a properly humidified environment, periodic cleaning is necessary to control both water and household impurities. Bacteria or fungi may appear on the water surface, the sides, or bottom of your humidifier. A crusty deposit or scale may also appear and is composed of minerals that have settled out of the water. Annual cleaning is required for the efficient and safe operation of this humidifier. Fully loosen the thumb screw at the bottom of the unit cover. The screw will remain attached to the cover. To remove the cover from the duct, pull the bottom away and then lift up. Remove the water distribution tray, located above the evaporator pad. It is held in place by a snap that must be lifted to pull out the tray. Pull the evaporator pad and frame assembly away from the duct, being careful not to disturb the drain connection. Remove the old evaporator pad and discard. Inspect the interior of the humidifier and remove any mineral deposits and accumulation from the frame assembly and drain tray. Remove the new evaporator pad from the plastic bag and insert into the frame assembly, with the black spot facing up. Ensure that no part of the evaporator pad is outside of the frame. Return the evaporator pad and frame assembly to their original position inside the humidifier.

Water Distribution Tray Felt wicking allows even distribution of water across surface of evaporator pad. As mineral deposits build up, the tray will effectively channel the water through the evaporator pad. [. . . ]
