Installation
Instructions
Positioning the Unit
The dehumidifier should be placed in the area where dehumidification is desired most.
Adjacent rooms in which dehumidification is also desired should allow adequate
airflow in and out of the space containing the dehumidifier.
• Do not use outdoors.
• This dehumidifer is intended for
indoor residential applications
only. This dehumidifier should
not be used for commercial or
industrial applications.
• Place the dehumidifier on a smooth,
level floor strong enough to support
the unit with a full bucket of water.
• Allow at least 8” of air space on all
sides of the unit for air circulation
(at least 16” for air outlet).
• Place the unit in an area where
the temperature will not fall below
41°F (5°C). The coils can become
covered with frost at at lower
temperatures, which may reduce
performance.
• Place the unit away from any
clothes dryer, heater or radiator.
• Close all doors, windows, and
other openings to the outdoors in
the room.

NOTICE
While operating on continuous and Max
modes, the humidity setpoint cannot be
adjusted manually.
Mode Button:
Press this button to change the mode of the
dehumidifier between Set mode, Max mode,
and Continuous run mode.
Set – The dehumidifier runsuntil the humidity
setpoint has been reached. The dehumidifier
will begin running once the humidity rises
above the setpoint again.
Max – The dehumidifier will run continuously
on High Fan.
Continuous – The dehumidifier will run
continuously and the fan speed can be
changed in this operating mode.
Bucketless mode:
Bucketless mode allows you to run the
unit without the bucket in place. The
included drain hose or a garden hose
must be attached and sloped towards
the drain for proper bucketless mode
operation. Figure 8 shows a proper slope
while figure 9 shows an improper slope.
The drain must be located below the
dehumidifier. For best drain performance,
we recommend the end of the drain hose
be 4 inches below the hose connection.
To activate bucketless mode, the following
steps must be completed within three
minutes of plugging the dehumidifier in.
1. Press and hold the up and fill level
buttons for 3 seconds until the
bucketless icon appears on the display.
2. Ensure the dehumidifier is on a flat
level surface (free of debris).
3. Make sure the hose for Bucketless
mode is sloped down to thedrain
(see fig. 8) and does not rise above
the connection point (see fig. 9).
To remove the unit from bucketless
mode, place the unit back on the bucket.

display will show P2 regardless of power status.
• Using proper lifting techniques, remove the unit from
the bucket. Be aware, some residual water may spill
from the bottom of the unit while not on the bucket.
• Using two hands, grab the bucket handle and carry
it to the desired drainage point. Pouring from a front
corner of the bucket (the bucket window is on the
front side), empty the bucket. If pouring from the
back of the bucket, some water may spill from the
relief holes.
• Return the bucket to the desired operating location
and place the unit back on the bucket. Be sure the
unit is aligned properly. Fig. 10
Fig. 11
NOTICE
• When you remove the unit from the bucket do not
set the unit on any electrical components as the
bottom may be wet.
• Do not set the unit on an uneven surface after
removing it from the bucket.
• Ensure the unit is seated properly after returning it
to the bucket.
• If the unit is removed from the bucket during
operation, the display will show the error code Eb
and cease operation until returned to the bucket
or changed to bucketless mode.

the wet area before moving the unit.

Page 15 
Operating
Instructions
• Make sure the hose is secure so there are no leaks.
• Direct the hose toward the drain, making sure that there are no kinks that will stop
the water flowing.
• Place the end of the hose into the drain.
• Select the desired humidity setting and fan speed on the unit for pump draining
to start.
• When operating in Bucketless mode the pump cannot be used.
NOTICE
The pump operation light blinks when a failure occurs. Please turn off the unit and
disconnect the power cord. Check the following items:
• Cleaning the pump filter:
- Clean the pump filter following the instructions below.
• Check if the drain hose is clean and free of debris.
• Empty the water from the bucket.
• Check the hose connection and the bucket for proper fitment. If the error
persists, contact Customer Service.
NOTICE
If routing the drain hose outdoors, do not operate when the outdoor temperature
is at or below 32°F (0°C) as the water will freeze, blocking the hose and causing
the unit to stop.
Make sure to empty the bucket at least once a week a week when using the pump
draining feature. When the pump draining feature is not being used, remove the
pump drain hose from the outlet.
