4. Setup
- Unpacking: Carefully remove the dehumidifier from its packaging. Retain the packaging for future storage or transport.
- Positioning: Place the unit on a firm, level surface in the area where dehumidification is needed. Ensure there is at least 8 inches (20 cm) of space around the unit for proper airflow. Do not place it against a wall or furniture that could obstruct the air intake or exhaust.
- Initial Standby: If the unit has been tilted or inverted during transport, allow it to stand upright for a minimum of 24 hours before plugging it in. This allows the refrigerant to stabilize.
- Drainage Setup:
- Manual Drainage (Water Tank): Ensure the water tank is correctly inserted into the unit. The unit will automatically stop operating when the tank is full and indicate a 'Full Tank' alert.
- Continuous Drainage (Drain Hose): For continuous operation without emptying the tank, connect the provided 6.56-foot drain hose to the drainage port on the back of the unit. Ensure the hose is sloped downwards to allow gravity drainage into a suitable floor drain or larger container. Avoid kinks or blockages in the hose.
- Power Connection: Plug the power cord into a grounded electrical outlet.
