Drainage Options
Your Smiandi dehumidifier offers two convenient methods for water removal:
1. Manual Drainage (Water Tank)
- The unit is equipped with a 2-liter (0.53 Gallon) removable water tank.
- When the tank is full, the dehumidifier will automatically shut off, and an indicator light/alert will notify you.
- Carefully pull out the water tank, empty the collected water, and reinsert it securely. The unit will resume operation.
2. Continuous Drainage (Drain Hose)
- For continuous, hands-free operation, connect the included 3.28 ft (1 meter) drain hose to the continuous drainage outlet on the back of the unit.
- Ensure the hose is sloped downwards to allow gravity to drain the water into a suitable floor drain or large container.
- Do not allow the hose to be kinked or blocked, as this will prevent proper drainage.
