2.5.5. The nitrogen bottle
Due to safety regulations, BESTnv cannot ship a nitrogen bottle. The bottle of nitrogen therefore has to be
provided by the Purchaser (For specifi cations: see table 2.2). BESTnv will supply a pressure control valve
and plastic tubing. The plastic tubing will be laid and connected to the GENIUS Compact by the Purchaser
prior to the installation visit (see picture 2.5.22 and 2.5.23). You will notice a fi ne tube is connected to the
nitrogen out-connection, this is normal and the tube should not be removed or connected to anything.
Attention: - Nitrogen bottle and regulator have to be installed at a dry and secure place.
In accordance with safety regulations the nitrogen bottle has to be fi xed to the
wall.
- Be very careful when moving the nitrogen bottle! Should the tap be seriously
damaged, due to a fall for example, the bottle could ignite and even explode,
causing serious damage.
BESTnv’s service engineer will check the installation during his installation visit and shall then pressurize
the system. The Purchaser will not pressurize the system without prior permission of BESTnv. The
nitrogen bottle should be installed within 25 m / 82 ft (standard length of tubing) of the GENIUS Compact
sorter.
