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

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

then screw DRAIN CAP back onto the unit. Place
the other end of the hose in the location you want
the water to go: to a floor drain, a water container,
or through a basement window to the outdoors.
(Pump can lift water up to 15 feet above the unit.)
Check hose for kinks or other obstruction. Make
sure end of hose will not be submerged in water
as this may cause a backflow into the unit and
cause a leak.

4. Reattach the DRAIN CONNECTOR end of
garden hose to the dehumidifier (Fig.4) then
check hose for kinks or obstructions. The position
of the hose at the floor drain must be lower than
DRAIN CONNECTOR.
After cleaning, replace the bucket cover
and slide the bucket into the unit. (Fig.3)
Check the float switch to make sure it is not
obstructed. Proper position of the bucket
and the float switch is required for the
dehumidifier to turn on.

CLEANING FRONT GRILLS AND AIR FILTER
1. Remove front grill by pulling out bottom towards
you (Fig.1). Then hold the top of the grill and
lift up gently to remove grill completely (Fig.2).
2. Pull the bottom of the filter out and lift the filter
out (Fig.3).
5. Keep the DRAIN CAP for future use when
emptying bucket manually.
Note : The filter is extremely flexible.
The removal of the filter will not damage the filter

3. Wash with mild detergent and rinse thoroughly.
Air dry away from direct sunlight.
Float Switch
CAUTION: Do not remove the bucket while
the pump is operating. This will cause the dehumidifier
to stop operating and result in an “E3” error message.
ALSO: The pump drain hose should not be both
under water AND at a height that is above the
dehumidifier. This can cause a “back flow” to the
dehumidifier and cause the dehumidifier to stop
working resulting in an “E3” error message. Following
an “E3”error, the unit must be unplugged and reset
to operate. (See Error Code section of this manual.)
4. Install filter and grill back into unit following
reverse directions listed above.

3. Check to make sure that there is nothing
blocking the connection at the base of the
pump or the bucket.
4. Reinstall the bucket, taking care that it is
installed properly.
5. Check to make sure that the pump drain
hose is not crimped or blocked.
6. Check to make sure that the pump drain
hose is not both under water and sitting at
a height above the dehumidifier – this can
cause a “back flow” of water from the hose

Generally when temperatures drop
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.
