Empting the water tank
When the water tank is full or has not been positioned
well, the 'water full'
indicator will light up and the unit will shut off automati-
cally.
To move the water tank, pull it out squarely from the unit
by using the attached
handle. After empting the water tank, place the water tank
into space.
Make sure it is properly positioned, in order for the 'water
full' indicator to go out
and your dehumidifier is operational.
Continuous drainage
When the dehumidifier is operated at very high humidity
levels, the water tank
will require more frequent drainage. In this situation, it
may be more convenient
to set the unit up for continuous drainage with the fol-
lowing procedures:
1. Remove the water tank.
2. Position the spout as shown in the diagram.
* The unit will not operate without the water tank, unless
the spout is properly
positioned.
3. Place one end of an appropriately sized drain pipe over
the spout.
4. Place the other end of the pipe in a drain, ensuring it is
not kinked or coiled.
5. Ensure the water will always drain away freely and the
hose will remain in
place.
6. In very cold weather, precautions must be taken to pre-
vent the drain pipe
from 'Water full' cutout.
