Introduction
CAUTION
Read the entire manual carefully and completely before installing this product. Installation and maintenance
should be completed by qualified personnel. Installation contrary to these guidelines may void warranty.
The benefits of a properly humidified environment are many. They include personal comfort as well as
the preservation of furniture, draperies, carpets, wooden floors and cabinets, paintings, pianos, etc.
Higher humidity levels can also increase the growth-rate of mold, bacteria, viruses, and even dust mites
in the home. Your home can be more comfortable at a warmer temperature with drier air than without
controlling humidity during the humid summer months. Since every degree of temperature change
represents about 3% to 5% of the total cooling costs, each degree warmer you can set the thermostat
can represent a significant annual savings.
During the cooling season, warm, moist air infiltrates the home and must be cooled. When cooled, this air
can still be humid as air conditioners are designed to cool the air, not dehumidify the air. A small amount
of dehumidification may be a benefit of air conditioners, but they actually work harder and longer to cool
the air when the air is moist. Only by using a whole house dehumidifier to reduce the humidity in the entire
home’s air, can a balance between humidity levels, temperature, comfort, and energy costs be optimized.
