Attachments (e.g. pipe holders, additional units, fastening parts,
etc.) directly to the compressor are not permissible!
Provide adequate clearance for maintenance work.
Ensure adequate compressor ventilation.
Do not use in a corrosive, dusty, damp atmosphere or a com-
bustible environment.
Setup on an even surface or frame with sufficient load-bearing
capacity.
Single compressor preferably on vibration damper.
Compound connection basically rigid.
Damage possible.
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).
Material soldering / welding connection: S235 (JRG2C)
The pipe connections have graduated inside diameters so that pipes with
standard millimetre and inch dimensions can be used.
The connection diameters of the shut-off valves are rated for maximum
compressor output. The actual required pipe cross section must be
matched to the output. The same applies for non-return valves.
