8 Maintenance
Regular maintenance is to be performed with use in an operation prone to explosion. Defective parts and
components are to be replaced. Only replacement parts approved by the pump manufacturers are to be
used.
The operator alone is responsible for the performance of monitoring procedures, maintenance
and inspections. The procedures used are to be documented in written form.
So that with easily inflammable gases no potentially explosive gas-air mixtures can arise, the compressor
must be sufficiently flushed with inert gas before the opening of the compressor as well as before the
reconnection after the opening of the compressor.
