Operating your dehumidifier

Control

Your dehumidifier has a control panel containing an indicator and two controls — Auto Shut-Off, Fan Speed, and Humidistat.

Auto Shut-Off ---This lamp glows when the bucket is full or is missing.

Fan Speed --- This controls the speed of the airflow.

Humidistat --- This controls the moisture in the room.

Unit operation

1. Turn the Humidistat to Off. Plug the power supply cord into an electrical outlet.

2. The Humidistat can be set anywhere between Off and Max for normal operation.

If you need more dehumidification, turn the Humidistat toward Max. If you need less dehumidification, turn the Humidistat toward Off.

3. Turn the Humidistat to Off to stop the unit.

4. If you want to control the speed of air flow, turn the Fan Speed toward Low or High.

NOTE: The Fan and compressor will not operate for about two minutes to protect the compressor when you turn the unit off and immediately back on.

De-icer control (invisible)

The Defrost Control senses frost build-up on the evaporator coil and automatically shuts off the compressor. The fan continues to run, drawing air across the coil, and melting the frost. When the coil is defrosted, the compressor automatically restarts, and dehumidifying resumes.

NOTE: Do not operate the dehumidifier at temperature below 65°F (18°C.) If your dehumidifier runs when the temperature and humidity conditions of room are low, frost can form on its evaporator coil. This interferes with proper operation. Therefore, dehumidifying performance may be reduced.
