[. . . ] 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.

Depending on the installation and furnace manufacturer the coil for this relay could be: · Wired in parallel with the coil of the NO fan relay, typically 24VAC. · Wired in parallel with the common and heating speed tap of the units blower typically 120VAC or 240VAC. · An inductively coupled current sensing relay on the common of the units blower. 5 Mounting Locations 1. This humidifier may be installed on either the supply or return plenum. The supply plenum is the preferred location because of higher evaporative capacity results. When there is insufficient space on the warm air plenum, the unit can be installed on the return duct. It is recommended that when the unit is installed in this location it is supplied with hot water service. If the furnace has an air conditioning coil, be sure the unit does not interfere with coil ends.

To remove the cover from the duct, pull the bottom away and then lift up. 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. 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. Return the evaporator pad and frame assembly to their original position inside the humidifier. Check the distribution tray to ensure that holes are clear of any scale build up. If desired, the distribution tray can be washed with mild detergent and warm water. Replace the distribution tray making sure the snap is hooked over the outside edge of the tray. Turn humidistat off. 8 Troubleshooting Common Questions & Answers Q. This is one of the most common questions from homeowners with new humidifiers. [. . . ] Must be cleaned or replaced when water flow is impeded or humidification is reduced. Evaporator Pad Allows water to evaporate as warm, dry air is drawn through it. Fluid Restrictor Located within the water tubing of the humidifier, it controls the amount of water that flows through the humidifier. Water Distribution Tray Felt wicking allows even distribution of water across surface of evaporator pad. [. . . ]
