Detailed Description: System Inspection: Shut down the AHU safely and opened the access panels. Inspected the filter frame and housing for any dust accumulation, debris, or damage. Filter Removal: Carefully extracted the old, saturated air filters (Pre-filters / Secondary filters) to prevent dust and particulate matter from dispersing into the unit. Cleaning & Sanitization: Thoroughly cleaned the filter rack and surrounding chamber surfaces to remove residual dirt before installing the new units. New Filter Installation: Installed the new set of filters ensuring the correct airflow direction (following the directional arrows marked on the filter frames). Verified tight sealing along all edges and gaskets to prevent air bypass. System Testing: Secured all access doors and restarted the AHU. Checked differential pressure readings across the new filter bank to confirm proper installation, balanced airflow, and baseline operational parameters. Result: The unit is operating efficiently with improved static pressure, optimal airflow, and enhanced indoor air quality (IAQ).
