Compressor assembly
4.5 Pipes
Pipes and system components must be clean and dry inside and free of scale, swarf and layers of
rust and phosphate. Only use air-tight parts.
Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being
cracked and broken by severe vibrations.
Ensure a proper oil return.
Keep pressure losses to an absolute minimum.
4.4 Pipe connections
The
pipe connections
have stepped internal diameters so that pipes with
standard millimetre and inch dimensions can be used.
The connection diameters of the shut-off valves are designed for maximum
compressor output.
The required pipe cross-section must be
matched
to the capacity. The same applies for non-return valves.

ATTENTION! Poor lubrication can damage the compressor.
Respect the stated values.

ATTENTION! Overheating can damage the valve.
Remove the pipe supports from the valve for soldering.
Only solder using inert gas to inhibit oxidation products (scale).
