5. MAINTENANCE
WARNING
All repair and maintenance work in the cabinet should be done by qualified technical staff
with knowledge about the maintenance procedures required by the cabinet.
Before starting any maintenance work or dismantling the cabinet, the area should be wiped
down with formaldehyde (
Annex A5.3
). Once this has been done, disconnect the cabinet
from the power socket.
In general, a regular control of the proper working of all cabinet components should be done
once a year.
5.1. MAINTENANCE TABLE
The frequencies determined for each operation, and in particular with regard to changing
filters, which appear on the Maintenance Table below are indicative values recommended for
normal cabinet service. Very severe work conditions may reduce the time intervals shown on
the Table.
TEST REGULARITY
Downflow filters integrity Test ( Annex A9.1 )
Minimum once a year or after
filter changes
Exhaust filters integrity Test ( Annex A9.2 )
Downflow air velocity test ( Annex A9.3 )
Set point alarm downflow air velocity test ( Annex A9.3.1 )
Inflow air velocity Test (Annex A9.4)
Set point alarm inflow air velocity test ( Annex A9.4.1 )
Smoke test ( Annex A9.5 )
Light test ( Annex A9.6 )
Recommended during the
start up of the cabinet
Noise level Test ( Annex A9.7 )
5.2. ABSOLUTE FILTERS
The average life of HEPA filters in these cabinets is 4000/5000 hours.
After this time, the propelled airflow falls because of the increased loss of load of the filter as
it is a mechanical filtering, although this does not mean that filtering efficacy is reduced.
When it reaches the minimum flows valued by the probes, the microprocessor activates
visual and acoustic alarms.
WARNING
Do not replace absolute filters or directly handle fans in MSCs without having first wiped the
area down with formaldehyde or another de-contaminating product. Opening the cabinet
without taking the proper precautions can endanger your health. We recommend it is carried
out by staff especially trained for this work.
When using formaldehyde the laws in force in each country must be followed.
