Setup
Unpacking
- Carefully remove the dehumidifier from its packaging.
- Remove all packing materials, including any tape or protective films.
- Inspect the unit for any shipping damage. If damaged, do not operate and contact customer support.
Placement
Place the dehumidifier on a firm, level surface in the area where moisture removal is desired. Ensure there is at least 8 inches (20 cm) of space around the unit for proper airflow.
Power Connection
Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the specifications of the unit.
Drainage Methods
Your Zafro dehumidifier offers two convenient drainage options:
- Manual Drain (Water Tank): The unit collects water in its internal 0.53-gallon water tank. When the tank is full, the dehumidifier will automatically stop operating and an indicator will light up. Empty the tank by carefully pulling it out, discarding the water, and reinserting it until it clicks into place.
- Continuous Drain (Drain Hose): For continuous operation without needing to empty the tank, attach the included 3.3-foot drain hose to the continuous drain port on the back of the unit. Route the hose to a floor drain or a suitable receptacle, ensuring the hose is sloped downwards to allow gravity drainage.

This image illustrates the two methods for water drainage: the manual drain method, which involves emptying the internal water tank, and the continuous drain method, which uses a hose connected to a drain outlet for uninterrupted operation.
Operating Instructions
The dehumidifier features an intelligent operation panel for easy control.
