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.
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.
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.
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.
2-5 Dryness Control The Dryness Control regulates the amount of moisture in the room. T urn the control knob clockwise for more drying. T urn the control knob counterclockwise for less drying. Turn the control knob to “Dry” to maintain average humidity conditions.
2-6 2. Use front and back handles to lift bucket. Sickness Hazard Do not drink water collected in water bucket. Doing so can result in sickness.
