CARE AND MAINTENANCE
Removing the collected water
1. Pull out the bucket a little.
There are two ways to remove collected water.
1. Use the bucket
When the bucket is full, the unit will automatically stop
running, and the Full indicator light will flash.
Slowly pull out the bucket. Grip the left and right handles
securely, and carefully pull out straight so water does
not spill. Do not put the tank on the floor because the
bottom of the bucket is uneven. Otherwise the bucket
will fall and cause the water to spill.
Throw away the water and replace the bucket. The
bucket must be in place and securely seated for the
dehumidifier to operate.
Fig.5
2. Hold both sides of the bucket
with even strength, and pull it
out from the unit.
The machine will re-start when the bucket is restored
in its correct position.

When you remove the bucket, do not touch any parts
inside of the unit. Doing so may damage the product.
Be sure to push the bucket gently all the way into the
unit. Banging the bucket against anything or failing to
push it in securely may cause the unit not to operate.
