Compressor assembly
4.5 Pipes
The
pressure and suction shut-off valves
have graduated inside di-
ameters so that pipes in the common millimeter and inch dimensions can
be used. The pipe will be inserted more or less deep, depending on the
dimension.
The connection diameters of the shut-off valves are designed for maximum
compressor performance.
The actual required pipe cross section must
be matched to the output. The same applies for non-return valves.

ATTENTION
An explosive atmosphere must not be present!
Do not solder as long as the compressor is under pressure.
Superheating can damage the valve. Remove the pipe supports
therefore from the valve for soldering and accordingly cool the
valve body during and after soldering.
Only solder using inert gas to inhibit oxidation products (scale).
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.
