The compressed air line system is connected at the
compressed air supply of the screw compressor
( - 1 - Fig. 10).
For this you should use a flexible connection
(e.g. compressed air hose, compensator).
Europe-Version: EN10226 R 2 1/2
(DIN 2999 – R 2 1/2)
USA / CANADA-Version: 2 1/2“ – 8 NPT
Warning
When connecting the compressor on the
mains side to the compressed air system
available at the customerʻs end, check the
operating temperatures and operating
pressures required and examine the
required connecting flange or the
connection thread for proper type, size and
functioning.
In the case of connections by means of
connecting hoses, take appropriate
measures to prevent whipping of the loose
end in the event that the hose connection
tears off (see Fig. 11).
6.3 Cooling water connection
(only Lxx W – water-cooled units)
Warning
If open cooling towers are used in the
cooling water circuit, it is possible for
legionella (Legionella pneumophila) and
other bacteria to grow and spread. The
growth and spread of bacteria must be
prevented by corresponding service and
water treatment methods.
Important
During danger of frost or extended periods of
standstill of the screw compressor unit, the cooling
water must be drained.
Maintenance and repair work must be carried out
carefully.
Dismantled bundles of pipes have to be checked
for integrity before being reinstalled. In the case of
even the slightest damage, replace the pipe bundle.
Always use new seals when carrying out assembly
work.
Note
When operating water-cooled screw compressor units,
the following must be taken into account:
• As a result of leakage in oil/water coolers, some oil
may get into the cooling water circuit.
• Cooling water must not be drained in an
uncontrolled manner into public sewage systems.
Uncontrolled overflowing of the oil separation
reservoir into public sewage systems must be ruled
out.
Strictly observe the relevant waste water regulations.
