5. Drainage Options
Your dehumidifier offers two methods for water removal: manual tank emptying or continuous drainage.

Figure 5.1: Comparison of the two drainage methods: a dehumidifier with its 1.7L manual water tank removed for emptying, and another unit connected to a 3.4 ft hose for continuous auto drainage.
5.1 Manual Drainage (Water Tank)

Figure 5.2: Image illustrating the Full Water Protection feature, where the dehumidifier emits a beep and automatically shuts off when the water tank is full, preventing overflow.
- The dehumidifier has a 0.52-gallon (2L) water tank.
- When the tank is full, the unit will automatically shut off, and the "Water Full" indicator light will flash.
- Carefully pull out the water tank using its handle.
- Empty the collected water.
- Reinsert the water tank firmly into the unit. The dehumidifier will resume operation.
5.2 Continuous Drainage
- For continuous operation without manual emptying, use the included 1.4-meter (4.6 ft) drain hose.
- Locate the drain port on the back of the dehumidifier.
- Connect one end of the drain hose to the port.
- Route the other end of the hose to a suitable drain (e.g., floor drain, sink) ensuring it is sloped downwards to allow gravity drainage.
- Ensure the hose is not kinked or blocked.
- If the included hose is not long enough, a standard garden hose can be used as an alternative.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your dehumidifier.
