2-1 PRODUCT OPERA TION THEOR Y OF OPERA TION WHA T IS HUMIDITY? Humidity is defined as the amount of water va- por in the air and is measured as a percentage of the amount of water vapor the air can hold at a given temperature. When the amount of water vapor exceeds 100%, the moisture can no longer remain suspended in the air , usually resulting i[...]

2-2 OPERA TING CHARACTERISTICS When a dehumidifier begins its run cycle, a partial frosting of the evaporator can be ob - served. This temporary frosting is limited by the operating conditions of the unit. In all cases, the frost should completely disappear within 10 to 15 minutes. In cool dry conditions, (65 ° F or lower tempera- tures, and rela[...]

2-3 F AN SPEED: Controls the fan operation, as follows: High: For faster moisture removal Low: For slower moisture removal Auto Fan Speed (Electronic Models): Automatically sets the fan speed based on the relative humidity of the room. Low speed is used when the relative humidity is within 5% of the Desired Humidity setting. High speed is used when[...]

2-4 Electrical Shock Hazard Plug into a grounded 3 prong outlet. Do not remove ground prong. Do not use an adapter . Do not use an extension cord. Failure to follow these instructions can result in death, fire, or electrical shock.
