It is important to follow the specific instructions provided by the manufacturer, as different models may require unique tools or components. Always review the installation guide in full before beginning the process.
Selecting the Installation Location
For HVAC-integrated systems, the air scrubber should be installed as close to the HVAC unit as possible, typically in the return air duct. This ensures that the scrubber treats the air before it enters the HVAC system. For standalone units, place the scrubber in the center of the room or an area with high air pollution levels.
Ensure the installation location is free of obstructions and allows for easy access to the unit for maintenance and filter changes. Proper airflow is crucial for the scrubber’s effectiveness.
Clearing the Area
Remove any debris, tools, or objects from the installation site to create a clean and safe working environment. This reduces the risk of accidents and ensures that the installation process can proceed smoothly.
Step-by-Step Air Scrubber Installation Process
The installation process involves several critical steps, including securing the unit, connecting it to the HVAC system (if applicable), and sealing any gaps to prevent air leaks.
Step 1: Turn Off Power
If the air scrubber is being integrated into an existing HVAC system, it is essential to turn off the power to the HVAC unit before beginning the installation. This step helps prevent electrical accidents and ensures a safe working environment.
Step 2: Position and Mount the Air Scrubber
For HVAC installations, position the air scrubber near the return air duct. Use mounting brackets or hardware provided by the manufacturer to secure the unit. For standalone units, place the scrubber in a central location with good airflow.
Ensure the unit is stable and properly supported. Use a level to confirm that it is mounted straight and will not tip during operation.
Step 3: Connect to the HVAC System
If the air scrubber is part of an HVAC system, attach it to the return air duct using screws or brackets. Seal any gaps with duct tape or sealing material to prevent air leaks. This step is crucial for maintaining system efficiency and ensuring that all air passes through the scrubber.
Some models may include a UV light, which should be installed near the air handler. This light helps break down organic pollutants and microorganisms.
Step 4: Install Filters
Follow the manufacturer’s instructions for installing filters. HEPA filters must be placed correctly to ensure optimal air purification. Some models may also require the installation of additional filters, such as activated carbon filters for odor control.
Make a note of the recommended filter replacement schedule, as regular maintenance is essential for continued performance.
Step 5: Secure All Connections
Double-check all connections to ensure they are secure and properly sealed. Any gaps or loose fittings can reduce the scrubber’s effectiveness and lead to inefficiencies in the system.
Final Checks and Testing
Once the air scrubber is installed, it is important to perform a series of final checks to ensure that it is operating correctly.
Power On and Test
Connect the unit to a power source and turn it on. Observe whether it powers up without any issues and whether air flows through the system as expected. If the unit is integrated with an HVAC system, power on the entire system and check for normal operation.
Verify Airflow and Efficiency
Listen for any unusual noises or vibrations that may indicate a problem. The unit should operate quietly and efficiently. Use an airflow meter or visual inspection to confirm that air is being drawn into the scrubber and distributed evenly throughout the space.
Seal Gaps and Recheck
Inspect the installation site for any gaps or leaks that may have been missed during the initial setup. Use duct tape or sealing material to close any openings and recheck the airflow for consistency.
Manufacturer’s Guidelines
