6. Operation

6.1 Humidity Control Adjustment

The humidity control is an adjustable switch that closes when the relative humidity of the air in which it is
located rises to the dial set point. It opens when the RH drops 4 to 6% below the set point.

Approximate Humidity Levels Per Setting

“Dry”

20% to 30% Relative Humidity

“Normal”

50% Relative Humidity (Recommended)

“Humid”

80% to 90% Relative Humidity

The dehumidifier will run until the relative humidity (RH) is reduced to the humidity control dial setting.

Quality humidity meters are available from the factory and are recommended to accurately monitor humidity
levels. Contact your dealer or call 1-800-533-7533 to order.

6.2 Blower (Fan) Switch

Turning the blower switch to

“FAN ON”

will cause the unit’s internal blower to run continuously, whether

the unit is dehumidifying or not. This function is desirable if the unit is used for air circulation.

Turning the blower switch to

“FAN AUTO”

will cause the unit’s internal blower to run only while the unit is

dehumidifying.

7. Maintenance

WARNING! NOTE: Do not operate the unit without the filter or with a less effective

filter. The heat exchange coils inside the unit could become clogged and require
disassembly to clean.
