If a drain is available, the unit can continuously drain water by attaching a commercially available hose (with
an internal diameter of 15 mm) to the drain. As the unit does not stop due to the water tank being full, it can
be operated for a long period of time without the need to empty the water tank. If there is power outage during
operation, once power is restored, the unit resumes in the mode it was operating before power outage.
z Commercially available hose (ID 15 mm)
Long enough to reach the drain.
Do not drain water continuously if there is
a possibility that temperature around the
hose could drop to freezing point.
Water inside the hose may freeze and prevent the water
in the tank from flowing out. The water may leak from
the unit and damage surrounding objects.
When draining water continuously or left unattended
for long periods, inspect the unit every two weeks.
When the filter or hose is clogged with foreign materials
or dirt, the dehumidification operation is disabled
and may cause leakage.
Turn off the power switch and unplug the power cord.
Remove the water
Remove the water tank.
Open the drainage outlet.
Use pincers to cut the three
fixing ribs, taking care not to
let them fall into the unit.
Insert the hose into the drainage outlet.
z Make sure the hose is in good condition free of bends and cracks.
z If it is hard to insert the hose, put it in water and then insert it. Do not use oils or lubricants.
z Inspect the hose once every 2 weeks. (Insects or dirt deposits in the hose may cause leakage.)
Position of drainage
Insert hose onto the drainage
outlet from the back.
Attach the commercially available hose (ID 15 mm)
to the continuous drainage outlet of the unit.
Confirm that the hose is
securely attached and
does not leak.
Confirm that the hose
does not show signs of
deterioration such as
cracks or bends.
Attach the tank, and set the end
of the hose into the drain.
If the tank is not reattached, the FULL lamp
remains on and operation is not possible.
