2. Light
3. UV

5.3 Clean the working bench of LAF with cotton moistened in filtered 70% IPA.
5.4 The airflow and UV should be kept “ON” for 30 minutes before carrying out work under LAF. Check the reading of the Magnehelic gauge; it should be between 10 to 15 pascal when airflow is on.
5.5 During working switch “OFF” the UV light and switch “ON” the tube light
5.6 After working, switch “OFF” the tube light and airflow of LAF.
