Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your VENTS-US TT 150 inline fan. Follow these steps carefully:

- Step 1: Drill the fan mounting plate. Securely drill the fan mounting plate onto a flat, stable surface where the fan will be installed. Ensure the surface can support the fan's weight.
- Step 2: Install the removable body. Once the mounting plate is fixed, carefully insert the fan's removable body (which contains the motor and impeller) into the installed mounting plate.
- Step 3: Lock the removable body. Secure the removable body by engaging the clamps or latches on the side of the fan casing. Ensure they are firmly closed to prevent movement.
- Step 4: Secure the latches. Use screws to further secure the latches, providing a robust and stable connection between the fan body and the mounting plate.
After mounting, connect the fan to your ducting using appropriate clamps or tape to ensure a secure and airtight airflow path. Ensure all electrical connections are made by a qualified professional and comply with local electrical codes.
Operating Instructions
The VENTS-US TT 150 fan is equipped with a simple two-speed control for easy operation.
- Speed Control Switch: Locate the toggle switch on the fan's casing. This switch allows you to select between two operational speeds:
- High Speed: Provides maximum airflow (252 CFM) for situations requiring rapid ventilation.
- Low Speed: Offers reduced airflow (167 CFM) for quieter operation and less intensive ventilation needs.
- Off: Position the switch to the center to turn the fan off.
- Power Connection: Ensure the fan is properly connected to a power source (119.99 Volts AC) before operation.

- Disassembly for Cleaning: To clean the fan, first disconnect it from the power supply. Unlatch and remove the central motor and impeller assembly from the fan casing. This allows for easy access to internal components.
- Cleaning Impeller and Casing: Use a soft cloth, brush, or vacuum cleaner to remove dust and debris from the impeller blades and the interior of the fan casing. For stubborn dirt, a damp cloth with mild detergent can be used, ensuring all parts are completely dry before reassembly.
- Reassembly: Once clean and dry, carefully reinsert the motor and impeller assembly into the casing, ensuring it aligns correctly. Secure the latches firmly.
- Frequency: The frequency of cleaning depends on the operating environment. In dusty or high-particulate environments, more frequent cleaning may be necessary to maintain optimal airflow and prevent motor strain.
