6. Drainage Options
The Tehanld dehumidifier offers two convenient drainage methods:
6.1 Manual Drainage (Water Tank)
For portable use, moisture collects in the built-in 5.5L (1.6 gal) water tank. When the tank is full, an indicator light will illuminate, and the unit will automatically stop operating to prevent overflow. Carefully remove the tank, empty the collected water, and reinsert it securely to resume operation.
6.2 Continuous Drainage (Drain Hose)
For hands-free, continuous operation, especially in high-humidity areas like basements, connect the included drain hose to the continuous drainage port on the unit. Route the hose to a suitable drain (e.g., floor drain, sink) ensuring it is sloped downwards for gravity drainage. This bypasses the water tank, allowing the unit to operate without interruption.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your dehumidifier.
7.1 Cleaning the Air Filter
The dehumidifier is equipped with a washable, reusable air filter. It is recommended to clean the filter every two weeks or more frequently depending on usage and air quality.
- Unplug the dehumidifier from the power outlet.
- Locate and remove the air filter (typically on the back or side of the unit).
- Wash the filter with warm, soapy water. Rinse thoroughly.
- Allow the filter to air dry completely before reinserting it into the unit. Do not use a dryer or direct heat.
7.2 Cleaning the Water Tank
Clean the water tank periodically to prevent mold and mildew growth. Use a mild detergent and warm water, rinse thoroughly, and dry before replacing.
7.3 Exterior Cleaning
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
