How a Dehumidifier Works

The dehumidifier removes moisture from the air by passing the moist air over a cold dehumidifying coil. The moisture condenses out of the air on this
coil and then drains from the coil into a bucket. A dehumidifier reduces the relative humidity of the surrounding air two ways. The removal of moisture
from the air (as just described) reduces its humidity. The relative humidity of the air is further reduced by heating as the dry air is discharged over
the condenser and out the front. The air is actually heated several degrees in this process. It is normal for the surrounding air to slightly increase in
temperature as the dehumidifier operates.

Before Calling for Service

Perform these simple checks
Condition – Unit is not working
• Is the dehumidifier connected to a live and correct voltage electrical supply?
• Is there a blown fuse or tripped circuit breaker? (Check the outlet with another appliance).
• Is the Power Switch pushed to the "I" position?
• Is the water container (if used) full and requires emptying?
• Is the water lever plastic float freely handing inside bucket (if bucket is used), or hangs freely in air (if no bucket)?
Condition – Moisture removal seems insufficient
• Are the dehumidifier's vents and air filter clear of obstructions and dirt?
• Does the location selected present sufficient airflow around the unit?
