4. Water Drainage
The dehumidifier offers two convenient methods for water drainage:
Manual Drainage:
The unit features a 6.5-liter water tank. When the tank is full, an audible alarm will sound, and the unit will automatically shut off to prevent overflow. Simply remove the tank, empty the collected water, and reinsert it to resume operation.
Continuous Drainage:
For continuous operation without the need to frequently empty the water tank, connect the included drainage hose to the designated outlet on the back of the unit. Ensure the hose is properly positioned to drain water into a suitable receptacle or floor drain.
