Continuous drainage
When dehumidifying, water can be stored in the water tank or
continuously discharged through a PVC tube (not included).
Before draining the water continuously, please remove the water tank
and connect a drain tube to the drain hole. Then replace the water
tank. The drainage tube should be placed lower than the drainage hole
to allow water to drain.
When the drain tube is not installed, water will drain directly into the
water tank. When the water tank is full, the screen will display "E4"
then the device will stop. At this point the tank should be emptied.
Notes
If you plan not to use your device for a long time, we advise you to
unplug it from the mains.
Before the 1st use of the device, please remove the water tank and
connect the water pipe into the drainage hole. Make sure the water line
is pointing vertically downward.
