    • The RLAF i.e. “Reverse Laminar Air Flow” is switched “ON” by pressing button on the panel 15-20 minutes before the dispensing activity starts.
    • Wait until the pressure differential across the HEPA filter comes within the limit.
    • If any abnormal noise or problem in instrument is observed then inform the engineering department for its repairing.
    • After achieving required differential pressure of gauge then allow for further dispensing activity.
    • Fill the differential pressure at start of shift as per Annexure – I.
    • After completion of activity switch off the RLAF and mains electric supply.
    • Remove the powder present. Affix the “TO BE CLEANED” label duly filled and signed.
