Maintenance
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.
7.3 Spare part recommendation / accessories
Available spare parts and accessories can be found on our compressor selection tool under
vap.bock.de
as well as at
bockshop.bock.de
.
Only use genuine Bock spare parts!

7.5 Decommissioning
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 appro
-
priate 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.
For operation with CO
2
the following oil types are necessary:
compressor version
ML(P)
and
S(P):
BOCK
lub E85
compressor version
SH(P):
BOCK C170E
DANGER
Compressors with the designation P in the marking (e.g.
HGX46/345 S
P
40 CO
2
T) are equipped with an LSPM motor.
After opening the compressor, there is a danger for people with
pacemakers or similar devices as well as metallic implants due to
a considerable magnetic field. A minimum distance of 50 cm from
the compressor motor must be maintained.
Cards with magnetic stripes (e.g. credit cards), mobile phones or
wristwatches can also be damaged.
Electrical voltage by induction! The motor must not be turned
when the terminal box is open.
As long as the compressor is closed, no magnetic field emanates
from it.
