Maintenance of the filter after use
• The filter has a very high adsorption capacity.
• At the time of an NBC attack and afterwards, do not detach the filter from
the air inlet opening. If the filter has adsorbed NBC substances, proceed
in accordance with the instructions of the Civil Defense Command.
At the end of the emergency situation, the company should be
summoned for a service check and maintenance of the filter.
• If there was no NBC attack, but the filter was attached to the wall nonetheless,
it is possible to detach it from the valve, to close the openings with the
sealing caps, and to arrange for a service check of the system.
Routine storage
• Close the air inlet valve (shock valve) by means of the decorative cover.
• Do not open the filter’s original seal or damage it in any way.
• In order to maintain the proper functioning of the system, perform a
service check once every two years, in accordance with the instructions
of Civil Defense Command.
