• Before cleaning, turn off the power and unplug the unit.
• Be sure the dehumidifier has been securely and correctly installed according to the installation instructions in this manual. Save this manual for possible future use in removing or installing this unit.
• Be sure the dehumidifier is properly grounded. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a three-prong grounding plug for protection against shock hazards.
• Your dehumidifier must be used in a properly grounded wall receptacle. If the wall receptacle you intend to use is not adequately grounded or protected by a time delay fuse or circuit breaker, have a qualified electrician install the proper receptacle. Ensure the receptacle is accessible after the unit installation.
• Be sure the electrical service is adequate for the model you have chosen. This information can be found on the serial plate, which is located on the side of thecabinet and behind the grille.

NOTICE
For accurate fill levels, ensure the bucket is empty before beginning operation.

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 the drain (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.

Timer Button:
Press this button to activate the Timer function. The Timer LED will illuminate indicating timer mode is being set. 0.0 will also appear on the display indicating the number of hours from now until the timer function will initiate.

3 minute compressor operation delay protection
After the unit has stopped, it can not be restarted in the first 3 minutes to protect compressor operation. The unit will restart automatically after 3 minutes.

Auto-Restart
If the unit stops unexpectedly due to power being cut, it will restart with the previous function setting (except bucketless mode) automatically when the power resumes.

Timer Function

• When activating the Timer function, you are setting the time until the unit changes its power state. This means, if the unit is on, activating the timer function will set the time until the unit will turn off. If the unit is off, activating the timer function will set the time until the unit will turn on.
• The time can be set after pressing the timer button then using the up or down buttons. These buttons will change the time in 0.5 hour increments up to 10 hours. After 10 hours, the time will change in 1 hour increments up to 24.
• If an error code appears during this time, the timer function will be cancelled.

NOTICE

• When first using the dehumidifier, operate the unit continuously 24 hours. Make sure the plastic cover on the continuous drain hose outlet is installed properly so there are no leaks.
• This unit is designed to operate in a working environment between 5°C/41°F and 35°C/95°F.
• Make sure the water bucket is positioned correctly so that the unit can operate properly. When the water in the bucket reaches a certain level, please be careful while moving the unit to avoid spilling.

Removing Collected Water
There are three ways to remove collected water:

Emptying the bucket

• When the bucket reaches the set Fill Level, the unit’s 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 thefront 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.

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.

Continuous draining

• Water can be automatically emptied from the unit into a sink, or other type of drain using the included hose.
• To install the hose, remove the drain cap from the rear of the unit and set aside. Insert the included drainhose, or attach a garden hose to the drain outlet. Place the other end of the hose on or near the drain so that water will drain properly.

1. Lift the unit off the bucket and place it on a level surface.
   

2. Lift the bucket using 2 hands and carry to drainage point.
   

3. Pour out all of the water.
   

• When removing the drain hose, some water may remain in the hose or the drain outlet. Be sure this water will not spill by drying the wet area before moving the unit.
  

NOTICE
When using the continuous draining feature, ensure the unit is placed above the sink or drain being used. This will ensure proper draining.

Pump draining (some models)

• Water can be pumped from the unit into a sink or other type of drain by putting the unit in pump mode and attaching the included pump hose. Be sure to install both the inlet and outlet pump hoses as shown in the figures on the right.

• To install the pump hose, remove the plug from the pump drain hole and firmly attach the the included pump hose as shown in Fig. 14.
  

• Initiate pump mode by holding both the up and down arrows for three seconds.

• The pump inlet hose must be placed in the bucket in order to pump the water out of the bucket.

NOTICE
The pump may generate a loud noise for the first 3~5 minutes of operation.

• 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.
