Setup Guide
1. Inline Duct Fan and Carbon Filter Assembly
The inline duct fan and carbon filter work together to provide optimal air filtration. Follow these steps for assembly:
- Attach the Carbon Filter: Connect one end of the carbon filter to the intake side of the inline duct fan. Secure it tightly with one of the provided stainless steel clamps.
- Connect Ducting: Attach the flexible ducting to the exhaust side of the inline duct fan. Use another stainless steel clamp to ensure a secure, airtight connection.
- Mounting: Use the included hanging straps to suspend the assembled fan and filter unit within your grow tent or desired ventilation area. Ensure the unit is level and securely fastened.

2. RJ12 Speed Humidity Controller Connection
The RJ12 Speed Humidity Controller allows for precise control over your fan's operation.
- Connect RJ12 Cable: Locate the RJ12 port on the inline duct fan and on the controller. Connect the provided RJ12 cable between these two ports. No additional power cable is needed for the controller as it is powered by the inline fan.
- Power On: Plug the inline fan's power cord into a suitable electrical outlet. The controller display should illuminate, indicating a successful connection.

Operating Instructions
1. Fan Operation
The inline duct fan features an energy-efficient EC motor designed for quiet and powerful performance.
- Airflow: Provides 205 CFM (Cubic Feet Per Minute) of airflow.
- Noise Level: Operates at a low noise level of 26.8 dB.
- Speed Control: The fan speed can be adjusted via the RJ12 controller or a compatible app.

2. RJ12 Speed Humidity Controller Functions
The RJ12 controller offers various modes to manage your environment:
- Manual Mode: Directly set the fan speed from 25% to 100%.
- Time Slot Mode: Schedule specific start and stop times for the fan to operate, along with desired running and standby speeds.
- Cycle Mode: Set the fan to run for a specified duration and then pause for another set duration, repeating the cycle a chosen number of times.
- Environment Mode: Prioritize either temperature or humidity. The fan will automatically adjust its speed to maintain your target environmental parameters.
- CO2 Device Control: The controller includes a switch to manage a connected CO2 device, if applicable.

Maintenance
1. Carbon Filter Maintenance
The carbon filter is crucial for odor control. Regular maintenance ensures its effectiveness and extends its lifespan.
- Pre-filter Cleaning: The pre-filter captures larger particles. It should be removed and cleaned regularly (e.g., weekly or bi-weekly, depending on usage) by washing with warm water and mild soap, then air-dried completely before reinstallation.
- Carbon Filter Replacement: The RC412 activated carbon has a finite lifespan. Replace the carbon filter every 6-12 months, or sooner if odor control effectiveness diminishes. The filter features a reversible flange to potentially double its life by flipping it.

2. Fan and Ducting Cleaning
- Fan Blades: Periodically inspect the fan blades for dust and debris accumulation. Clean gently with a soft cloth or brush. Ensure the fan is completely dry before resuming operation.
- Ducting: Check the flexible ducting for any tears, kinks, or blockages that could impede airflow. Replace damaged ducting as necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan not turning on | No power, loose connection, controller off | Check power outlet, ensure all cables are securely connected, verify controller is on and in an active mode. |
| Poor airflow | Blocked filter, kinked ducting, low fan speed setting | Clean or replace pre-filter, check ducting for obstructions, increase fan speed setting on controller. |
| Persistent odors | Saturated carbon filter | Replace the carbon filter. Ensure proper sealing of all connections. |
| Controller not responding | Loose RJ12 cable, power issue | Ensure RJ12 cable is firmly connected to both fan and controller. Check fan power. |
