OPERATING INSTRUCTIONS
CONTROLS
LOCATION
Be sure to set up the dehumidier on a level oor, with at least 8” (20 cm) of clearance on the sides and
back and 15” (40 cm) on top. The unit is designed to be used within a temperature range of 41°F (5°C) -
95°F (35°C). It should be close enough for a properly grounded 3-prong outlet for the cord to easily reach.
a. Power: Turns the dehumidier on and off.
b. Filter: The check lter feature is a reminder to clean the Air Filter for more efcient operation. The
Filter light will illuminate after 250 hours of operation. To reset after cleaning the lter, press the Filter
button and the light will go off.
c. Cont.: Press to activate the continuous dehumidifying operation.
d. Fan
• Press the FAN button to select either HIGH or NORMAL fan speed.
• Set on HIGH for maximum humidity removal. Set to NORMAL when humidity has been
reduced or when quieter operation is preferred.
e. Timer (Timer Set Control)
• If the unit is on, pressing the Timer button once will start the Auto-Off stop program, and the
Off indicator light above the timer button will be lit. Pushing the Timer button again within 5
seconds will switch to the Auto-On start function, and the On indicator will be lit.
• If the unit is off, pushing Timer will start the Auto-On start feature, and pushing it again within 5
seconds will switch it to the Auto-Off stop feature.
• Press or hold the UP or DOWN button to set the Auto time in 0.5 hour increments, up to 10
hours, then at 1 hour increments up to 24 hours. The control will count down the time remaining
until starting or stopping.

• Turning the unit ON or OFF at any time or adjusting the timer setting to 0.0 will cancel the Auto
Start/Stop timer program.
• If the P2 code occurs, the Auto Start/Stop program will be cancelled.
f. + and - (Humidity Set Control Buttons): The humidity level can be set within a range of 35% RH
(Relative Humidity) to 85% RH in 5% increments. The lower the set % is, the drier the air will be.
g. Indicator Lights
• Filter – Filter needs to be cleaned
• Full (Bucket full light) – Empty water bucket
• Cont. - Continuous dehumidifying light
• On (Timer on light) – Auto On/Start set.
• Off (Timer off light) – Auto Off/Stop set
• Turbo - High fan light
• Normal - Low fan light
• Auto Defrost - Auto defrost on
h. LED Display: Displays the relative humidity level for the room (±5%) within a range of 30%-90%.
While setting, displays the set level for humidity between 35%-85%, or the auto start/stop time
(0~24), along with error or protection codes.
Error Codes
• AS: Humidity Sensor error
• ES: Temperature sensor error.
• EC: Refrigerant leakage (on models with this feature)
Protection Code
• P2: Water bucket full or incorrectly
installed.
NOTE: If the display shows one of the above codes turn off and unplug the unit, and check for any
obstructions or empty the water tray, then restart. If code is still present, turn off again and unplug,
and contact customer service or service technician for assistance.
SMART FUNCTIONS
• Auto Shut Off: When the water “Full” indicator light turns on or the humidity setting is reached, the
unit will be shut off automatically.
• Delayed Start: When the unit has stopped or power is interrupted, it will not restart 3 minutes to
protect the cooling system. The dehumidier will automatically start after 3 minutes have passed.
• Auto Defrost: When frost builds up on the evaporator coils, the compressor will cycle off and the fan
will continue to run until the frost melts.
• Auto-Restart: If the power is lost or cut, the unit will restart with the previous function setting
automatically when the power resumes.
DRAINING WATER
There are two ways to remove water
collected while the dehumidier is
running.
1. Manually empty the water bucket:
When the bucket is full, remove
from the back of the unit and
empty.

2. Continuous Draining: Water can be drained automatically into a oor drain by
attaching the threaded female end of a 5/16” I.D. water hose (sold separately)
to the drain hose adaptor located in the water bucket. Remove the plastic
cover from the drain outlet on the back of the unit and set aside. Remove the
water bucket and insert the drain hose through the drain outlet. Securely press
the drain hose of the adaptor into the connector on the front of the unit. Tighten
the adaptor securely with the included two screws (located in the bucket).
Drain Hose
Adaptor A
Make sure the connection is tight and there is no leak. Attach the water hose and run it to the oor
drain or a suitable drainage facility, making sure that it is lower than the drain outlet of the unit. The
water hose should slope downward to allow the water to ow out smoothly.
NOTE: When the continuous drain feature is not being used, remove the drain hose from the
outlet and put the plastic cover back onto the drain outlet.

CARE AND MAINTENANCE
WARNING: Turn the dehumidier off and remove the plug from the wall outlet before maintenance or
cleaning.
• DO NOT use ammable liquids or chemicals to clean the unit.
• DO NOT immerse in or spray with water to clean.
• DO NOT operate the unit if the power cord is damaged.
• The water bucket should be cleaned every few weeks or as needed. DO NOT leave water in the

CLEAN THE AIR FILTERS
Clean the air lter with water at least once every 30 days, or as needed. The lter can be taken out by
removing the water bucket and pulling the lter down from behind the grill.
CAUTION: DO NOT operate the dehumidier without the lter as dirt, dust and lint will clog it and
reduce performance.
STORAGE
To store the dehumidier for long periods, turn off and unplug the unit, then allow it to sit for one day
before emptying the water bucket or removing drain hose to ensure complete water drainage. Wipe down
the exterior of the unit, and clean the water bucket and lter. Wrap the cord up with the power cord band
on the rear of the unit. Cover with a plastic bag, and store upright in a dry, well-ventilated place.
