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 the 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.

NOTICE

When you remove the unit from the bucket, do not set the unit on any electrical component, 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 it aside. Insert the included drain hose, 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.
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 included pump hose as shown in Fig. 10.
Initiate pump mode by holding both the up and down arrows for three seconds.
The pump inlet hose must be placed in the bucket 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 from flowing.
Place the end of the hose into the drain.
Select the desired humidity setting and fan speed on the unit for the 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 when using the pump draining feature. When the pump draining feature is not being used, remove the pump drain hose from the outlet.
