The fertilizer/acid tanks and lines
For the setup of the fertilizer/acid tanks and lines, the following components should be installed:
Items of the fertilizer/acid tanks and lines
Component
Specifications
13
Fertilizer/acid stock tank Between 1 and 6 fertilizer/acid solution stock tanks
14
Manual valve (fertilizer)
A manual ball valve on each fertilizer/acid line at the stock tank outlet
15
Fertilizer/acid filter
≤ 130 µm (≥ 120 mesh)
The following aspects should be taken into account:
•
Ensure the stock tanks are of sufficient size for storage of at least one day's consumption.
•
Sufficient space should be available between the fertilizer/acid tanks and the NetaJet™ 4G,
to enable inspection and maintenance operations.
•
For the connection of fertilizer supply lines to the NetaJet™ 4G, use a transparent, chemical-resistant,
reinforced PVC water hose with an internal diameter of 16 mm that will not contract when there is
a vacuum in the system.
•
Use properly sealing stainless steel band clamps for the fertilizer/acid hose connection, type SS 316.
CAUTION
After completion of the hydraulic infrastructure, before the installation of the NetaJet™ 4G, rinse
the hydraulic infrastructure and fertilizer/acid lines and tanks by running water through them in
order to wash away any residues (chips, shavings, sawdust) from the setup work.
Hydraulic infrastructure preparation
The hydraulic infrastructure preparations should be performed according to the mode of the NetaJet™ 4G
to be installed. Before performing the infrastructure installation, see the typical setup for the specific mode
of NetaJet™ 4G to be installed (
).
Required infrastructure proportions*
To enable optimal operation of the NetaJet™ 4G, piping must maintain the following proportions.
*Refer to the typical setup illustration for each mode,
