7.2 Work to be carried out
In order to guarantee optimum operational reliability and service life of the compressor,
we recommend
carrying out servicing and inspection work at regular intervals:
Oil change:
- not mandatory for factory-produced series systems.
- for field installations or when operating near the application limit: for the first time after 100
to 200 operating hours, then approx. every 3 years or 10,000 - 12,000 operating hours.
Dispose of used oil according to the regulations; observe national regulations.
Annual checks: Oil level, leak tightness, running noises, pressures, temperatures, function of
auxiliary devices such as oil sump heater, pressure switch.
Only use genuine GEA Bock spare parts!

7.5 Decommissioning
7| Maintenance
Close the shut-off valves on the compressor. CO
2
does not need to be recycled and can therefore
be blown off into the environment. It is essential to ensure good ventilation or conduct the CO
2
into
the outdoors to avoid danger of suffocation. When releasing CO
2
, avoid a fast drop in pressure to
prevent oil from exiting with it. If the compressor is unpressurized, remove the piping on the pressure-
and suction-side (e.g. dismantling of the shut-off valve, etc.) and remove the compressor using an
appropriate hoist. Dispose of the oil inside in accordance with the applicable national regulations.
When decommissioning the compressor (eg. for service or replacement of the compressor) larger
amounts of CO
2
in the oil can be set free. If the decompression of the compressor is not sufficient
enough, closed shut-off valves may lead to intolerable excessive pressure. For this reason the
suction side (LP) and the high pressure side (HP) of the compressor have to be secured by
decompression valves.
