5.0 Procedure
5.1 Repairing or cleaning of the HEPA filter shall not be carried out.
5.2 Replacement of Fresh Air Filter, Pre Filter Micro Vee filter and cartridge filter will be under following circumstances
5.2.1 Whenever any puncture is observed in the filter element during its inspection, replace the Filter in the respective location with the same specification of filter.
5.2.2 Whenever the filter frame found destructed from its original shape, replace the filter.
5.2.3 Whenever filter elements get permanently chocked due to accumulation of abnormal dust or fiber particles on the filter and that can not be removed by cleaning of filter as per the filter cleaning procedure, then replace the filters.
5.2.4 If the differential pressure of the respective area or Filters are fluctuated from the its Specified limit which may raise doubt regarding the performance of filter then check it visually. If the filter condition found unsatisfactory then replace it.
5.3 Replacement of HEPA Filter.
5.3.1 Whenever HEPA filter integrity test results found not within the limits of the acceptance criteria of HVAC validation Protocol.
5.3.2 Ensure the following points during replacement of filter.
5.3.2.1 During Replacement of HEPA filters due to above said criteria, same shall be replaced with proper change control procedure.
5.3.2.2 The filter replacement to be done when only the respective activity of area or equipment in stop condition.
5.3.2.3 Dispose off the damaged filter, as per SOP No-ER/088-00.of Disposal procedure of engineering waste.
5.3.2.4 Make the necessary entry in filter replacement record.
5.3.2.5 Perform the test of respective filters and areas as SOP for HVAC Validation.
5.3.3 Procedure for UV Lights
5.3.3.1 Removing:
5.3.3.1.1.1 Switch off the mains of UV tube.
5.3.3.1.1.2 Remove UV tube by opening the threaded plug provided at the end of system.
5.3.3.1.2 Slowly pull of the UV tube and disconnect the electrical wires.
5.3.3.1.3 Keep UV tube at the safe area.
5.3.3.2 Fixing:
5.3.3.2.1 Connect the electrical wires to new UV tube.
5.3.3.2.1.1 Slowly insert the UV tube inside the jacket system and direct it to get fixed inside the holder.
5.3.3.2.1.2 Plug the system by closing the thread.
5.3.3.3 Frequency
5.3.3.3.1 Once after 7500 Hrs or when lamp damaged.
