10. e set point That signal tells the humidifier to energize the electrodes in the canister to generate steam provided the indoor unit blower is on If the blower activation relay is installed a call for humidity will turn on the indoor unit blower It is important to anticipate changes in outdoor temperature and adjust the setting accordingly to avoid excessive condensation when outdoor temperature is low For example with an outdoor temperature of 20 F the correct setting will be 35 If the temperature is expected to fall to 0 F that evening then merely reduce the setting to 25 several hours prior to the temperature change See Table 2 for the recommended settings These settings which are based on years of research represent a compromise between humidity levels that would be most desirable for comfort and humidity levels that are suitable for protection of your home and to avoid condensation on your windows For example a wintertime indoor humidity of 50 may be considered ideal for comfort but unfortunately it probably would result in condensation which can cause damage to your home Observing the recommended humidity levels on your Humidifier Control is an important safeguard Condensation of water on the inside surface of windows in the form of fogging or frost is usually an indication of too much humidity This same condensation can occur in other areas in your home possibly resulting in damage TABLE 2 Outdoor Temperature

17. umidifier delivers humidity in the form of steam to the conditioned space via the HVAC system duct or optional Model 1 854Y Fan Pack The humidifier generates steam by energizing two electrodes that extend into a canister of water Current flowing between the electrodes causes the water to boil creating steam Water is introduced to the humidifier through a fill valve to a fill cup located in the top of the cabinet The fill cup serves as an overflow reservoir and provides an air gap between the humidifier and water source The steam canister is filled from the bottom The canister is seated in a drain cup assembly which includes a drain valve The drain and fill valves work together to maintain water level in the canister to deliver the rated steam capacity based on the electrical conductivity of the water and to temper drain water See Figure 1 for representation of fill and drain system and canister Steam is delivered into the airstream through a dispersion tube mounted in the HVAC system ductwork Openings in the dispersion tube are fitted with tubelets which extend into the center of the tube The design of the dispersion tube and tubelets distribute steam over a wide area in the duct and direct any condensed moisture back into the steam hose FIGURE 1 Fill and Drain System and Canister Steam Outlet Fill
