For best results, position a Simplicity dehumidifier with at least 8 inches of clearance from other objects in a room with a temperature between 42 and 95 degrees. The dehumidifier should also be close enough to an electrical outlet so that the use of an extension cord is not necessary.
Dehumidifiers draw air through the machine and over coils filled with cooled refrigerant. The temperature of the air is lowered and moisture is removed as condensation, which is collected in a reservoir for disposal. This process requires unimpeded airflow and an air temperature within a certain range for optimal results.
