4.3 Connecting the pipelines
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
NOTICE
!
!
Potential chemical reactions due to air penetra-
tion!
Proceed swiftly and keep shut-off valves closed
until evacuation.
4.3.1
Pipe connections
The pipe connections are suitable for pipes in all com-
mon dimensions in millimetres and inches. Brazed con-
nections have stepped diameters. The pipe will im-
merge more or less depending on its dimensions. If ne-
cessary, the bushing may even be cut at the end with
the largest diameter.
4.3.2
Shut-off valves
During operation: Only operate the shut-off valves
either fully opened or fully closed.
• Remove the protective cap.
• First loosen the packing gland with ¼ turn to the left.
• Then open or close the valve spindle.

• After that, retighten the packing gland and screw the
protective cap on again.
Any installation position and flow direction can be
chosen.
CAUTION
Depending on the operation mode, the shut-off
valves may become very cold or very hot.
Risk of burning or frostbite!
Wear suitable protective equipment!
NOTICE
!
!
Do not overheat the shut-off valves!
Cool the valve body during and after the brazing
operation.
Maximum brazing temperature 700°C!
When turning or mounting shut-off valves:
NOTICE
!
!
Risk of damage to the compressor.
Tighten screws crosswise in at least 2 steps to
the prescribed tightening torque.
Test tightness before commissioning!

Pipelines
Use only pipelines and system components which are
• clean and dry inside (free from slag, swarf, rust and
phosphate coatings) and
• which are delivered with an air-tight seal.
