Compressed Air Supply - Graco 2K device EcoMix 2000 User Information

should be connected to appliances and the earth by soldering, welding or stable screw fittings. Do not
use chains. When making connections or during repair work, in particular to pipelines, ensure that the
conductive path is not interrupted by non-conductive parts.
The grounding connection must be tested for correct working conditions
by a qualified engineer.
−
Grounding points on the appliances are appropriately marked:
Portable, conductive vessels or appliances that can be electrically charged must also be grounded
This is usually achieved by means of a flexible connection, secured e.g. by a clip.
−
Do not use chains.

COMPRESSED AIR LINE
When a compressed air line needs to be installed, it must have a gradient of 3 to 5 mm per meter
down to the compressed air tank or the moisture trap. When a branch line has to be installed from an
existing compressed air line, it should connect above the line axis.
When installing curved metal airlines, they should be selected
with a bend radius on the tube axis not smaller than 2.5x the
outside diameter of the line.
- Plastic lines in locations with an explosion hazard must have a
conducting resistance to earth of < 10
