buttons for 3 seconds until the 
bucketless icon appears on the 
display. 
2.  Ensure the dehumidifier is on flat 
level ground (free of debris).
3.  Make sure the hose for bucketless 
mode does not rise above the 
connection point on the unit.
4.  Attempting to change the unit into 
bucketless mode while it is sitting 
on the bucket will have no effect.
To remove the unit from bucketless 
mode, place the unit back on the 
bucket.
