Troubleshooting
IF LOW AIR VELOCITY
Step 1.
Check prefilter media; replace or clean as necessary.
Step 2.
Adjust SSSC clockwise for higher blower output.
Step 3.
Check power supply for proper voltage, amperage, and distribution frequency.
Step 4.
Replace HEPA filter if the air velocity remains low.
IF HIGH AIR VELOCITY
Adjust SSSC counterclockwise for lower blower output.
NON-LAMINAR FLOW AND/OR EXCESSIVE CONTAMINATION
Step 1.
Ensure that no large obstructions are upstream of airflow pattern.
Step 2.
Determine that no other air-moving devices are operating in or around cleanroom which disrupt room’s airflow pattern.
Step 3.
Check air velocity and, if low, conduct the “Low Air Velocity” procedure outlined above.
Step 4.
Conduct smoke and photometer test on HEPA filter. Seal or replace HEPA filter as necessary.
