SETTING UP YOUR DEHUMIDIFIER  
CHOOSING THE PROPER LOCATION  
* Place the dehumidifier on a level floor  
strong enough to support the unit with a  
full bucket of water  
* For best performance, allow at least  
12-18 inches of air space on all sides of  
the unit for good air circulation  
DEFROST OPERATION  
WARNING  
- The dehumidifier has a built-in defrost control  
that senses frost buildup on the evaporator coils  
- During defrosting, the compressor will  
automatically turn off; the fan will continue  
running to defrost the coils until a majority of  
the frost has melted.  
To reduce the risk of fire, electric shock or injury to persons, read the important  
SAFETY INSTRUCTIONS found on page 3 before operating this appliance.  
* Use the dehumidifier:  
-
in the basement to help prevent moisture  
damage.  
AUTOMATIC SHUTOFF  
-
When the bucket is full, or when the bucket is not  
in the proper position, the bucket full light will  
turn on and the unit automatically shuts off  
The bucket must be placed in the proper position  
for the dehumidifier to work. The light will stay  
on and the dehumidifier will not run if the bucket  
is not in the proper position.  
- in the kitchen, laundry room, bathroom,  
and spa/exercise areas that have excessive  
moisture  
- to prevent moisture damage anywhere  
books or valuables are stored  
-
- during construction or remodeling to  
reduce drying time for drywall and paint  
- The dehumidifier will shut off once the desired  
humidity setting has been reached.

Pump setting button is selected when using the  
automatic pump feature with included 18 ft. hose  
To select the pump as your water removal option,  
press the pump button (4). When the pump  
indicator (13) is on, the pump will automatically  
remove the water in the bucket only when the  
bucket is full. The pump light must be on at all time  
to use this function. It will only turn on for a period  
of 30 seconds to remove the water. The pump will  
turn off after 30 seconds and not turn on again until  
the bucket is full again. It is normal for a small  
amount of water to remain in the bucket after the  
pump has operated; this is to protect the pump.  
The pump button should be off at all times except  
when the user chooses this as their option to remove  
collected water (See Page 7, Option 3). The pump  
option should only be selected when there is a ¼”  
hose properly installed in the pump drain location.  
If the pump button is pressed when using other  
disposal options, E3 (Error message – See page 10)  
will be displayed. If other disposal options are  
needed, push the pump button again to turn off the  
pump function.  
Dehumidifier pint capacity is defined as how  
much moisture it can draw out of the air in a  
24 hour period in 80 degrees F and 60%  
Relative Humidity. Once humidity begins to  
drop from 60%, the amount of moisture in  
the air begins to fall, which will result in less  
water in your bucket.

humidity level and fan speed is adjusted for optimum  
comfort (50%) with no manual adjustment needed.  
If a humidity adjustment arrow (15) or fan speed  
button (2) is pressed while in auto mode, the unit  
will switch to humidity mode automatically.  
* Humidity Mode  
To set desired humidity level when not in auto mode,  
push setting button (3) until humidity indicator  
(10) is lit. The humidity levels will adjust in increments  
of 5% beginning at a low of 35% and reaching a  
maximum of 70%. Humidity will show in the display  
when adjusting humidity level. To adjust humidity  
level up or down, press humidity adjustment  
arrows (15) until desired humidity level is reached.  
* Cycle Run Time  
To set the unit into continuous mode, push setting  
button (3) until continuous indicator (12) is lit.  
Continuous mode will run the compressor and fan  
continuously until it is powered off or until another  
setting is inputted. When continuous mode is  
programmed, “Co” will be displayed. Fan speed  
can be adjusted in this mode.  
3. Select Your Fan Speed  
By pressing fan speed button (2), fan speed will  
change. The indicator (8) of selected fan speed  
will light (High or Low). In Auto Mode, fan speed  
will adjust the fan speed automatically depending  
how close the room humidity is to 50%. For example,  
if the room is 70%, the unit will need to pull in air  
quickly, so it will turn on high. Once the room  
reaches 55%, the unit will slow the amount of air  
flow and turn the fan on low. Fan Speed can be  
adjusted in all settings except for auto mode.  
To set Cycle Run Time, push setting button (3)  
until cycle run time indicator (11) is lit. In this  
setting, the unit will run for either 3, 6, or 12 hours,  
then shut off for 3, 6, or 12 hours, then turn on

outside during colder seasons,  
humidity levels drop causing the  
amount of moisture in the air to be  
minimal. This will result in the unit  
not drawing as much water as it does  
during warmer seasons.
