3. Setup
3.1 Unpacking
Carefully remove the dehumidifier and all accessories from the packaging. Retain packaging for future storage or transport.
3.2 Placement
The SF-Dehumidifier is uniquely designed for grow tents. It can be placed outside the grow tent to prevent adding heat that could affect plant growth inside. Ensure the unit is on a stable surface.

3.3 Air Duct Connection
Attach the connecting components onto the dehumidifier's top outlet. Then, connect one end of the air duct to the connecting component and the other end to your grow tent's designated port. This allows dry air to be directed into the tent.

3.4 Humidity Sensor Connection
Connect the temperature/humidity sensor wire to the designated port on the dehumidifier. Place the sensor inside your grow tent, near the plants, for accurate humidity readings. Avoid placing it directly in the path of the air duct outlet.
3.5 Drainage Setup
The dehumidifier offers two drainage methods:
- Water Tank: The unit has a built-in 2.1-liter water tank. When the tank is full, the 'full water' indicator will light up, an alarm will sound, and the unit will automatically stop. Empty the tank and reinsert it to resume operation.
- Continuous Drain: For continuous operation, connect the provided drain pipe to the drainage outlet on the back of the unit. Route the hose to a suitable drain or a larger collection container.
