Position Your Dehumidifier

For best results, operate your dehumidifiers in an enclosed area. Close all doors and windows. Place your dehumidifier away from obstructions, and keep it away from anything that could block airflow into and out of the dehumidifier.

Plug in Electrical Cord

IMPORTANT
Please let the dehumidifier stand upright for 24 hours before initial plugging in

The dehumidifier needs to be plugged into a properly grounded 120 volt outlet rated for at least 16 amps. Uncoil the power cord and plug it firmly into a suitable outlet.

Note : When the dehumidifier is first plugged into AC power, the control panel display will light up for a second, which is part of the dehumidifier’s self-diagnosis procedure and no user intervention is required.

Understand the Control Panel

The control panel on the dehumidifier has an LCD screen and 4 buttons. Press the POWER Button to turn the dehumidifier on. The LCD screen will light up and display the readout as below.

Understand the Control Panel

What is on the LCD Screen?

Big Font Digital Number (43 RH% on the above illustration) is humidity percentage reading the inlet air that the dehumidifier detects which is similar to the room humidity level. When you are pressing the ↑ or ↓ button to set a desired humidity percentage value, the big font digital number will turn to display the setting value and flash.

Small Font Digital Number (34 °F on the above illustration) is temperature reading of the inlet air which is similar to the room temperature. However, if the timer function is being set or has been activated, the small font digital number will turn to display the timer setting value for time remaining.

Running Icon ：Running icon flickers typically because the compressor has not kicked in. It usually happens 1) when the dehumidifier is under the 3-minute compressor delay status; 2) when the dehumidifier is programmed to delay-start (AUTO ONTIMER).

Wet Controller Icon: Wet Controller Icon flickers when the room humidity level (inlet humidity reading) is 3% lower than the set humidity.

When you see the “wet controller” icon illuminating while setting up, it typically means the set humidity level is not 3% lower than the inlet humidity reading. Please make sure the set humidity value is at least 3% (10% recommended) lower than the inlet humidity reading.
In Humidistat Mode, if you see “wet controller” icon illuminating after running the dehumidifier for a while, it means the dehumidifier has got the room humidity downtotheset point and the dehumidifier enters into standby mode.

Defrosting Icon: The dehumidifier begins to defrost when the frost has accumulated on the interior of the dehumidifier. When the dehumidifier is defrosting, the fan is running, but the compressor is not, the defrost icon is flashing. The dehumidifying function will cease until the frost has melted. When defrosting is complete, the defrosting Icon will disappear and the dehumidifier begins to dehumidify

Note: The frequent defrost process indicates that the room temperature is too cold. Therefore, if the room temperature is lower than 60°F, please consider adding heat to promote proper drying.

Fan Icon: The fan icon illuminates when the fan is running

Water Droplets Icon: The water droplets icon illuminates when the compressor kicksin, which means the dehumidifier is dehumidifying. When the compressor delays to start duet the 3-minutes delay system, this icon flickers.

Caution: Water tank must place in right position, other wise will cause the water full alarm.

Timer Icon: Timer icon illuminates when the timer function is enabled.

Note:
- The dehumidifier with a humidistat will stop and start automatically to maintain room humidity level within a range of ±3% of the set point.
  For example, if the set humidity is 50%
- when the inlet humidity level the dehumidifier detects is 47%, 3% lower than the set humidity, the dehumidifier will automatically stop and enter into “wet controller” mode.
- when the inlet humidity level the dehumidifier detects raises to 53%, 3% higher than set humidity, it will automatically restart.
- However, if the set humidity level is equal to or lower than 30, the dehumidifier will enter CONTINUOUS MODE where the dehumidifier will run continuously.
Turn the dehumidifier off
Press the Power Switch to turn the dehumidifier off. Note: To protect the compressor, the fan will continue to operate for 5 seconds after the dehumidifier has shut off. So please do not disconnect the power cord to force the dehumidifier to stop. Always use the power button.

Continuous Drain by Gravity

Water can be automatically be emptied into a floor drain by attaching the included drain hose.

To Achieve Continuous Drain by Gravity:

Remove the plastic cover from the continuous drain outlet;
Attach one end of the drain hose to the drain outlet;
Direct the other end of the drain hose down to a suitable drainage facility, like a floor drain.

Note

Make sure the connection is tight and there is no leaking.
Be sure to run the water hose sloping downward to let the water flow out smoothly. No kinks or bent.
If the condensation water would be drained out to an external container via the hose, be sure NOT to submerge the other end of the hose into the drained out water.
It is recommended to use a short hose. If the drain hose is too long, water may not drain completely, which can lead to stagnant water and mildew build up inside the hose.
When the continuous drain feature is not being used, remove the drain hose from the outlet andplacethe drain outlet cover back.
