FAN 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 the relative humidity reaches or exceeds 5% of the Desired Humidity setting.

DRYNESS CONTROL: Controls the amount of moisture in the room. Set the control to the normal setting to maintain average humidity conditions. Adjust the control to a higher or lower setting for more or less drying.

When the dehumidifier is first installed, the customer may wish to set the Dryness Control to the DRYER setting to remove extra moisture from furnishings, as well as the room air.

When the humidistat senses the desired hu- midity level has been reached, the control cycles off the compressor and fan motor. On electronic control models, 30 minutes after the unit cycles off at the desired relative humidity, the compressor and fan will be cycled back

on. If the relative humidity has not increased, the unit will only run for 3 minutes. There is a 3 minute minimum “on” or “off” time used to protect the compressor that requires at least 3 minutes of run time or off time before the compressor stops or restarts.

The reason for the compressor to be turned on 30 minutes after it cycles off is that when the unit cycles off, heat from the condenser and fan motor rises up toward the control. This higher temperature lowers the relative humidity around the humidistat and the unit will not run even if the relative humidity in the room is rising. This assures the room relative humidity is properly monitored. The unit will not cycle off and on when set to continuous run.

ADJUST/EMPTY BUCKET LIGHT: When this light is “ON,” it indicates that the unit is not running (see “Setting The Controls, Types 1, 2, or 3 on Pages 2-4 and 2-5). Look for the following conditions:

The bucket is full: Empty the bucket and replace it in the dehumidifier.

The bucket is not correctly installed in the unit: Remove and replace the bucket in the unit so that it fits all the way in. Make sure the light is off, or the dehumidifier will not run.
